03CEA05334437846FDE0B5ECAD4EF80D.taxon	diagnosis	Diagnosis Specimens of S. aumatlapalli sp. nov. examined from the CNIN were found intermixed with S. favilla sp. nov. and S. penguinifera (Dyar, 1910). The absence of a dark red outlining around the white patterning of the forewing apex and hindwing underside separates this species from S. favilla; additional more subtle differences of the hindwing underside also separate the two: notably, the longitudinal, medial white band is continuous in S. aumatlapalli (see right arrow, Fig. 1 b), but interrupted at the postmedian in S. favilla (see right arrow, Fig. 7 b). Stamnodes aumatlapalli sp. nov. is more strongly marked above and bears a slightly darker orange-yellow ground colour than S. penguinifera. The hindwing underside is markedly different from that of S. penguinifera and can be easily identified by the curved, transverse, medial white band near the posterior inner margin of the hindwing underside that angles distad toward the tornus (see left arrow, Fig. 1 b). The same band is straight, thicker, and angles basad in S. penguinifera (see left arrow, Fig. 3 b). When viewed in conjunction with the longitudinal, medial white band, S. penguinifera appears to have a large Y-shaped mark in the center of the hindwing underside; such is absent in S. aumatlapalli. The number, shape, and orientation of cornuti on the vesica immediately separates S. aumatlapalli sp. nov. from S. penguinifera and S. favilla sp. nov. The vesica of S. aumatlapalli bears an echinate field of several dozen small cornuti over much of its surface (Fig. 41 b), while S. favilla has a dense spinose cluster of approximately nine cornuti of varying size that are much larger and more heavily sclerotized than S. aumatlapalli (Fig. 46 b), and S. penguinifera has dozens of cornuti in a dense cluster (Fig. 43 b). Female genitalia of S. aumatlapalli are similar to those of S. penguinifera and S. favilla in size, shape, and signum attributes. While S. aumatlapalli and S. favilla appear to consistently have a laterally sclerotized area of the corpus bursae; such appears to be absent in studied preparations of S. penguinifera. Stamnodes aumatlapalli sp. nov. appears to be most closely related to S. cannonaria (Schaus, 1927). The latter is known only from the Guatemalan volcanic highlands. The Isthmus of Tehuantepec represents a significant biogeographic boundary, dividing the Trans-Mexican Volcanic Belt, Northern Oaxacan Highlands, and Sierra Madre del Sur from the volcanic highlands of Guatemala. Stamnodes aumatlapalli can be separated from S. cannonaria by the presence of an oblique patch of ground colour within the black apical area of the forewing (this may be variable), and subtle differences of the hindwing underside that include a fine, dark grey outline around the white patterning and a lighter grey patch colour. Stamnodes cannonaria has a darker, nearly black, patch colour. Although the male genitalia of both species are similar, there are notable differences. The acuminate lateral processes of the juxta in S. aumatlapalli appear to be thinner and more widely separated, spanning the width of the vinculum, whereas those of S. cannonaria are roughly twice as thick, about one-quarter longer, and not as wide as the vinculum. In addition, the small cornuti on the vesica of S. aumatlapalli appear to be about one-half to one-third the size of those of S. cannonaria; however, only one male specimen (TAM- 2021 - 104) of S. cannonaria was available for genitalic study.	en	Matson, Tanner A.

03CEA05334437846FDE0B5ECAD4EF80D.taxon	etymology	Etymology The specific epithet aumatlapalli is derived from the Latin word for gold, ‘ aurum ’, represented by the double vowel ‘ au’, and the Aztecan Nahuatl root ‘ mātlapalli ’, meaning ‘ wings’. When these two parts are combined, they form the name ‘ golden wings’. The name is a noun in apposition. See Remarks section for further explanation of this name.	en	Matson, Tanner A.

03CEA05334437846FDE0B5ECAD4EF80D.taxon	distribution	Distribution (Fig. 74) Mexico: Stamnodes aumatlapalli sp. nov. is primarily an inhabitant of the pine-oak woodlands of the Sierra Madre Oriental and Trans-Mexican Volcanic Belt; its distribution in the Sierra Madre Oriental appears to be primarily southern, corresponding to the Hidalgoan subprovince (Morrone 2020). An unusual observation was recorded from Zacatecas on iNaturalist (Observation: 1804430); this moth may be misrecorded. The arid region where this individual was observed is far removed from the typical habitat of S. aumatlapalli and until a second observation can be confirmed, this record will be considered suspect and omitted from range maps and discussion.	en	Matson, Tanner A.

03CEA05334437846FDE0B5ECAD4EF80D.taxon	biology_ecology	Biology Stamnodes aumatlapalli sp. nov. was collected with S. ferropulvisa sp. nov. in Santiago de Anaya, Hidalgo. The immature stages remain unknown, but from knowledge of visually similar Stamnodes, it is predicted this species will likely be hosted by local mints (Lamiaceae). Adults are likely bi- or multivoltine as adult collections span much of the year: February, June, July, September, and October.	en	Matson, Tanner A.

03CEA05334437846FDE0B5ECAD4EF80D.taxon	discussion	Remarks This species was described as part of a project undertaken by Mr Isaac Russell’s 2019 – 2020 eighth-grade science class from Topeka, Kansas. With COVID- 19 disrupting educational classrooms, Mr Russell contacted me to assist with a proposed adaptation to his curriculum that would keep his students engaged and learning while they were isolated in their homes. A working group of interested students received lectures on topics such as evolutionary biology, systematics, biodiversity, Mexican biogeography, and the process of describing new species. Students were then given the opportunity to select the name for this new taxon as long as it alluded to the morphology of this species or was related to its country of origin, Mexico. Mr Russell’s eighth-grade science class enthusiastically proposed the new species name, Stamnodes aumatlapalli sp. nov.; its etymology speaks to both morphology and native language and culture.	en	Matson, Tanner A.

03CEA053344F7848FD80B56BA805FE1A.taxon	diagnosis	Diagnostic remarks Stamnodes penguinifera is less strongly marked and with a lighter orange ground colour than S. favilla sp. nov. and S. aumatlapalli sp. nov. The hindwing underside is markedly different from that of aforementioned taxa and can be easily identified by the straight, thick, transverse, medial, white band that angles basad toward the inner margin (see left arrow, Fig. 3 b). Stamnodes penguinifera appears to have a large Y-shaped mark in the center of the hindwing underside (Fig. 3 b) that is absent in S. aumatlapalli (Fig. 1 b) and S. favilla (Fig. 7 b). This species also lacks the dark red perimeter that surrounds the white patterning of the forewing underside apex and hindwing underside of S. favilla. The number, shape, and orientation of cornuti on the vesica may also separate S. penguinifera from visually similar Stamnodes. The vesica of S. penguinifera has dozens of cornuti in a dense cluster (Fig. 43 b), while S. aumatlapalli sp. nov. bears an echinate field of several dozen small cornuti (Fig. 41 b), and S. favilla sp. nov. (Fig. 46 b) has a dense cluster of approximately nine cornuti of varying size that are much larger and more heavily sclerotized than those of S. aumatlapalli. The female genitalia of S. favilla and S. aumatlapalli are very much like S. penguinifera in size, shape, and signum attributes; however, examined material of S. penguinifera lacks an asymmetric lateral sclerotization of the corpus bursae found in the other two species. Redescription Dyar’s original description of S. penguinifera did not describe genitalic morphology. To his description, the following genitalic redescription and associated images are supplemented: MALE GENITALIA (Fig. 43). Uncus long, slender, and tapering. Subscaphium well developed. Juxta wide and broadly U-shaped with posterolateral, long, curved, acuminate-conical processes. Inner surface of valva with two hair tufts: smaller tuft arising basally from digitate tubercle; second, larger, more laterally widened tuft residing in slight depression and extending to subapical area of valva. Costal sclerite terminating just short of apex. Vesica bearing dozens of spinose cornuti in dense cluster. FEMALE GENITALIA (Fig. 62). Ovipositor short. Anterior apophysis two-thirds length of posterior apophysis. Ductus bursae short and narrow with prominent sclerite flattened on ventral surface and dorsolaterally rolled toward median. Corpus bursae ovoid (very much like that of S. favilla sp. nov. and S. aumatlapalli sp. nov. but without the posterolateral sclerotization of corpus bursae) with circular and depressed signum bearing minute papillae; signum situated at anterior third of corpus bursae.	en	Matson, Tanner A.

03CEA053344E784BFD33B5DDAE4DFA7F.taxon	diagnosis	Diagnosis Stamnodes clara sp. nov. is phenotypically most similar to S. carota sp. nov. and S. favilla sp. nov.; however, the latter species inhabits the Sierra Madre Oriental and is believed to be allopatric. Additionally, the white patterning of the forewing underside apex and hindwing underside are outlined with dark red scales in S. favilla, while in S. clara, the white patterning of the same areas are outlined in dark grey. The ground colour of S. clara also appears to be given more toward orange-yellow than the deeper orange ground colour of both S. favilla and S. carota. In S. carota sp. nov. the transverse medial white band of the hindwing underside is larger and more complete than in S. clara sp. nov. (see left arrows, Figs 4 b, 6 b). However, the number and arrangement of cornuti on the vesica appears to be especially diagnostic: S. clara has a tight cluster of approximately four large cornuti (Fig. 44 b), while S. carota contains a patch of 16 – 20 cornuti of greatly varying size (Fig. 45 b).	en	Matson, Tanner A.

03CEA053344E784BFD33B5DDAE4DFA7F.taxon	discussion	Remarks I have identified a possible second individual whose wing pattern deviates from the holotype of S. clara sp. nov. that I cautiously consider a conspecific. This specimen is currently housed at the EMEC (voucher: EMEC 1748437) and its illustration can be found in Fig. 5. The most significant difference can be found in the white areas of the hindwing underside, which are notably more pronounced in the basal area. Further, the male juxta appears to be larger and the uncus more swollen at the base. Nevertheless, when considering other characteristics, this individual closely aligns with my understanding of S. clara. However, due to the limited availability of additional specimens of S. clara, defining meaningful species variation remains intractable.	en	Matson, Tanner A.

03CEA053344D784DFDCAB247A8CAFAAD.taxon	diagnosis	Diagnosis The diagnosis of Stamnodes carota sp. nov. should be considered provisional due to limited records of its visually similar – and likely sympatric – congener, S. clara sp. nov. The ground colour of S. carota appears to be darker orange than S. clara, and the transverse medial white band of the hindwing underside is larger and more complete. However, it appears the most diagnostic feature can be found in the male genitalia. The vesica of S. carota contains a patch of 16 – 20 cornuti of varying size, whereas S. clara has a tight cluster of approximately four spinose cornuti. Stamnodes carota sp. nov. is also phenotypically similar to S. favilla sp. nov.; however, the two species appear to be allopatric, with S. carota inhabiting the Sierra Madre Occidental and S. favilla inhabiting the Sierra Madre Oriental. The white patterning of the forewing underside apex and hindwing underside are outlined with dark red scales in S. favilla, while in S. carota, the white patterning of the same areas are outlined in dark grey.	en	Matson, Tanner A.

03CEA053344B784FFDCAB137AFCBF9E0.taxon	diagnosis	Diagnosis Individuals of S. favilla sp. nov. may be confused with S. carota sp. nov., S. clara sp. nov., S. aumatlapalli sp. nov., and S. penguinifera. The dark red outlining of the white patterning of the forewing underside apex and hindwing underside distinguish S. favilla from the previous species. While Stamnodes favilla is phenotypically most similar to S. carota and S. clara, these species are allopatric – S. carota and S. clara inhabit the Sierra Madre Occidental while S. favilla inhabits the Sierra Madre Oriental. The number, shape, and orientation of cornuti on the vesica are diagnostic. The vesica of S. aumatlapalli sp. nov. bears an echinate field of several dozen small cornuti (Fig. 41 b); while S. favilla sp. nov. (Fig. 46 b) has a dense cluster of approximately nine spinose cornuti of varying size that are much larger and more heavily sclerotized than those of S. aumatlapalli; and S. penguinifera has dozens of spinose cornuti in a dense cluster (Fig. 43 b). The female genitalia of S. favilla sp. nov. are very much like S. penguinifera in size, shape, and signum attributes; however, S. favilla has a posterior, asymmetric lateral sclerotization of the corpus bursae not found in examined material of S. penguinifera. The female genitalia cannot easily be distinguished from those of S. aumatlapalli sp. nov.	en	Matson, Tanner A.

03CEA05334577853FDC7B247AE29FC27.taxon	diagnosis	Diagnosis Stamnodes matrona sp. nov. is not easily confused with other Stamnodes, but as this species is likely sympatric with S. favilla sp. nov., a brief diagnosis with respect to the latter is warranted. While S. favilla has a dark red outlining of the white patterning of the forewing underside apex and hindwing underside, such is absent in S. matrona. Furthermore, the male phallus altogether lacks cornuti, which should separate this species from S. favilla and all other similar species.	en	Matson, Tanner A.

03CEA05334547852FDB0B50EA963F9A3.taxon	biology_ecology	Biology Stamnodes fergusoni is univoltine with a peak autumn flight from September through October and a single generation with mature caterpillars from October into November. Over most of this species’ range, the pupa is believed to overwinter and remain in diapause until the following fall. Larvae (Fig. 93) are hosted by Salvia L. (Lamiaceae) and were reared to maturity on rock sage (Salvia pinguifolia (Fernald) Wooton & Standl.) in Arizona and New Mexico (Matson & Wagner 2020). Matson & Wagner (2020) also suggested this species may feed on shrubby blue sage (Salvia ballotiflora Benth.) in south Texas and Coahuila where S. pinguifolia is absent.

03CEA05334527858FDC5B632A8C4FA9D.taxon	diagnosis	Diagnosis Stamnodes disrupta sp. nov. may be confused with S. fervefactaria, S. fergusoni, S. mariachi sp. nov. and S. erupta sp. nov. The bright, white reticulate pattern of the underside of the hindwing and apex of the forewing stand in contrast to the more off-white to cream colour of the same areas in S. fervefactaria. Additionally, the lead grey patches on the hindwing underside are finely bounded by a thin dark grey edge in S. fervefactaria and S. fergusoni that is mostly absent in S. disrupta. Stamnodes disrupta is known from the northern Sierra Madre Occidental in the states of Sonora and Chihuahua, while visually similar sister species S. erupta is known from the vicinity of Mexico City. While the hindwing underside of S. disrupta bears a white, transverse medial band that gradually curves toward the tornus (see left arrow, Fig. 14 b), the same band in S. erupta is straighter as it angles toward the tornus (see left arrow, Fig. 16 b). The angle of this band affects the shape of the large lead-coloured patch near the tornus; in S. disrupta, this patch is more subovate, while in S. erupta, it is more triangulate. The basal inner margin of S. disrupta also appears to have more white scales along the inner edge of the large grey basal patch of the same area in S. mariachi and S. erupta (see right arrows, Figs 14 b, 15 b, 16 b). Stamnodes disrupta may also be separated from S. mariachi by the presence of a checkered forewing fringe and oblique white patch in apical area of forewing underside. Male genitalia readily separate S. disrupta sp. nov. (Fig. 49) from S. fergusoni (Matson & Wagner 2020: fig. 7). Stamnodes fergusoni has a juxta that bears posterolateral conical processes and its vesica has a large echinate patch of cornuti; these characters are absent in S. disrupta. However, the male genitalia of S. disrupta, S. fervefactaria, S. mariachi sp. nov., and S. erupta sp. nov. are exceedingly similar with only subtle differences. While the uncus of S. disrupta (Fig. 49 a) and S. fervefactaria is broadly swollen medially, that of S. mariachi (Fig. 50 a) and S. erupta (Fig. 51 a) tapers only slightly along its length and lacks an apparent medial swelling. The shield-like juxta of S. disrupta is larger, and more pronounced on its distal surface than in S. mariachi.	en	Matson, Tanner A.

03CEA05334527858FDC5B632A8C4FA9D.taxon	etymology	Etymology The species name disrupta is derived from the Latin word ‘ disrumpere ’, meaning ‘ to shatter’ or ‘ to break apart’. It alludes to the broken, white, hindwing underside pattern of this moth. The phonetic similarity with visually similar S. erupta sp. nov. is intentional to reinforce the close relationship between these two species.	en	Matson, Tanner A.

The bright, white reticulate pattern of the underside of the hindwing and apex of the forewing stand in contrast to the more off-white to cream colour of the same areas in S. fervefactaria. Stamnodes mariachi can be separated from all aforementioned species by the absence of a checkered forewing fringe and absence of an oblique white patch in the apical area of the forewing underside. Additionally, the black apical area of the forewing that broadly extends all the way down the outer margin to the tornus appears to be diagnostic. Male genitalia readily separate S. mariachi sp. nov. (Fig. 50) from S. fergusoni (Matson & Wagner 2020: fig. 7). Stamnodes fergusoni has a juxta that bears posterolateral conical processes and its vesica has a large echinate patch of cornuti; these characters are absent in S. mariachi.

Eight miles west of a different village – El Palmito, Durango – matches the mentioned elevation of 6400 ft, suggesting confusion in either the recorded elevation or the precise locality due to villages with identical names.

The bright, white reticulate pattern of the underside of the hindwing and apex of the forewing stand in contrast to the more off-white to cream colour of the same areas in S. fervefactaria. Additionally, the lead grey patches on the hindwing underside are finely bounded by a thin dark grey edge in S. fervefactaria and S. fergusoni that is absent in S. erupta. Stamnodes erupta is known from the vicinity of Mexico City, while Stamnodes disrupta is so far only known from the northern Sierra Madre Occidental in the states of Sonora and Chihuahua. While the hindwing underside of S. erupta bears a straight, white, transverse medial band that angles toward the tornus (see left arrow, Fig. 16 b), the same band in S. disrupta gradually curves toward the tornus (see left arrow, Fig. 14 b). The angle of this band affects the shape of the large lead-coloured patch near the tornus; in S. erupta, it is more triangulate, while in S. disrupta, it is more subovate. Additionally, the basal inner margin of S. erupta lacks the white scaling along the inner edge of the large grey patch of the same area found in S. disrupta (see right arrows, Figs 14 b, 16 b). Stamnodes erupta can be separated from S. mariachi by the presence of a checkered forewing fringe and oblique white patch in apical area of forewing underside. Male genitalia readily separate S. erupta sp. nov. (Fig. 51) from S. fergusoni (Matson & Wagner 2020: fig. 7). Stamnodes fergusoni has a juxta that bears posterolateral conical processes and its vesica has a large echinate patch of cornuti; these characters are absent in S. erupta. However, the male genitalia of S. disrupta sp. nov., S. fervefactaria, S. erupta, and S. mariachi sp. nov. are exceedingly similar with only subtle differences. While the uncus of S. disrupta (Fig. 49 a) and S. fervefactaria is broadly swollen medially, that of S. mariachi (Fig. 50 a) and S. erupta (Fig. 51 a) tapers only slightly along its length and is not noticeably swollen medially.	en	Matson, Tanner A.

03CEA05334657865FDCBB7DCAE29FC6E.taxon	etymology	Etymology The species name erupta was inspired by the moth’s striking colouration, which to an imaginative eye, may resemble the explosive eruption of a volcano. It is derived from the Latin verb ‘ erumpere ’, meaning ‘ to break out’ or ‘ to burst forth’.	en	Matson, Tanner A.

03CEA053346D786DFDCCB56BA8FAFD7B.taxon	diagnosis	Diagnosis Stamnodes saltillo sp. nov. is outwardly unmistakable from congeners. This species may resemble S. marmorata of the USA, as both share a striking checkered fringe and a hindwing underside heavily patched and striated with white upon a mostly black and red-brown base colouring. Whereas much of the brown scaling radiates over the veins in S. marmorata, it is only subtly so in S. saltillo. Though I only had access to a few S. saltillo individuals, the intraspecific colour variation of S. marmorata appears to be much greater than the relatively consistent colouring of S. saltillo. These two species do not overlap in distribution.	en	Matson, Tanner A. (2023): A review of Mexican Stamnodes (Lepidoptera: Geometridae) with the description of 16 new species.

03CEA053346D786DFDCCB56BA8FAFD7B.taxon	discussion	Remarks Preliminary phylogenetic analyses place S. saltillo sp. nov. sister to the Purshia - feeding S. marmorata (Matson & Wagner in prep.); however, both are nested among many Cercocarpus - feeding species and thus Cercocarpus Kunth (Rosaceae) should also be considered a potential host. A single paratype (USNMENT 01771222) from Cerro Potosí was labeled as from the state of San Luis Potosí, despite Cerro Potosí most often referring to a high mountain in Nuevo León. The high elevation given on the specimen label also suggests this individual was collected from Cerro Potosí in Nuevo León and not the state of San Luis Potosí. As such, Nuevo León is given in the Type material section in brackets and the estimated GPS coordinates are also based on a Nuevo León locality.	en	Matson, Tanner A.

03CEA05334777873FDFEB0F2A869FCE5.taxon	discussion	Remarks During my review of this species, I came across individuals from the Sierra Madre Occidental that were located as far north and west as western Durango, which was surprising as I had previously considered S. patamon to be exclusive to the Sierra Madre del Sur. However, after examining the male genitalia of these individuals from Durango, I regard them as the same species. A population that resembles S. patamon (S. nr patamon in Fig. 95) also extends into the northernmost areas of the Sierra Madre Oriental. Vitor Becker collected individuals in Gómez Farías, Tamaulipas, in May of 1997, and in Cerro Potosí, Nuevo León, in June of 1997. Unfortunately, I could only examine photographs of this material sent to me by Becker, as all but one specimen are held in his collection in Brazil, where regulations often prohibit biological material from leaving the country. However, one individual (Fig. 23) from Becker’s collection in Cerro Potosí is deposited at the USNM and has been barcoded. This specimen appears somewhat aberrant compared to most of the rest of Becker’s series and may represent yet another questionable entity. The COI barcode (BOLD Process ID: LNAUY 180 - 19) was found to be 3.5 % (pairwise) different from Oaxacan S. patamon. Although S. patamon from Durango, Guerrero, Oaxaca, and the putative S. nr patamon individuals from Nuevo León and Tamaulipas bear a subapical white patch on the forewing, this feature is lacking in the sequenced individual. The sequenced individual also has an overall lighter cream ground colour, and the medial transverse white patch on the hindwing underside appears straighter than the more arcing norm for S. patamon. Unfortunately, the sequenced individual is female, so I could not compare its genitalia to the entirely male series of S. patamon available for this study, nor to the putative individuals of S. nr patamon from Nuevo León and Tamaulipas in Becker’s collection in Brazil. For now, the sequenced individual will be regarded as the sole representative of a potentially undescribed species that warrants further investigation. In the Discussion and Figs 94 and 95, it is listed as Stamnodes sp. (? undescribed).	en	Matson, Tanner A.

03CEA05334747874FDC6B613A92FFE7E.taxon	diagnosis	Diagnosis In dorsal view, S. catarina sp. nov. could be confused with sympatric S. patamon or S. churro sp. nov.; however, the hindwing underside pattern and male genitalia unambiguously separate these taxa. The hindwing underside of S. catarina is lightly striated with dark brown to black scales and bears an ill-defined black discal spot (Fig. 26 b). In S. patamon, the hindwing underside is striated with dark brown and burgundy scales surrounding several large, ill-defined, all-white patches (Fig. 24 b), and in S. churro, the hindwing underside is cream coloured and speckled with light brown scales throughout (scales modestly darker in basal half of wing) (Fig. 27 b). The pale ground colour of S. catarina has a grey cast, while that of S. churro is tanner, and S. patamon given more toward yellow-cream. Stamnodes catarina sp. nov. is immediately distinguished from S. churro sp. nov. by its large spatulate uncus (Fig. 53 a) – the uncus of S. churro is small and triangulate (Fig. 54 a). Among numerous other differences, S. catarina can be separated from S. patamon by its juxta that bears a dense tuft of approximately 100 erect setae on its distal surface (Fig. 53 a). Stamnodes patamon only has a few spinose setae arising from the surface of the juxta, and bears large, sickle-shaped sclerotized ribbons on the inner face of valva (Fig. 55 a) that are absent in S. catarina. The vesica of S. catarina bears approximately eight large spinose cornuti, linearly decreasing in size (Fig. 53 b); while the vesica of S. churro has a large, central, echinate patch of several hundred small cornuti opposite of two, large, apical spinose cornuti (Fig. 54 b); and the vesica of S. patamon bears a single, large, spinose cornutus adjacent to a large patch of several hundred filamentous cornuti (Fig. 55 b). With male dissection, these species cannot be confused.	en	Matson, Tanner A. (2023): A review of Mexican Stamnodes (Lepidoptera: Geometridae) with the description of 16 new species.

The large spatulate uncus of S. catarina sp. nov. can be used to diagnose this species from S. churro sp. nov. without dissection. A brush may be used to remove caudal abdominal scales to reveal the large spatulate uncus. Likewise, the small triangulate uncus of S. churro can rarely be seen using this method.	en	Matson, Tanner A.

03CEA05334727877FDCDB640AE29F85B.taxon	diagnosis	Diagnosis In dorsal view, S. churro sp. nov. may be confused with sympatric S. patamon or S. catarina sp. nov., fortunately, the hindwing underside pattern and male genitalia unambiguously separate these taxa. The hindwing underside of S. churro is cream-coloured and speckled with light brown scales throughout (scales modestly darker in basal half of wing) (Fig. 27 b). In S. patamon, the hindwing underside is striated with dark brown and burgundy scales surrounding several large, ill-defined, all-white patches (Fig. 24 b), and in S. catarina, the hindwing underside is lightly striated with dark brown to black scales and bears an ill-defined black discal spot (Fig. 26 b). The uncus is small and triangulate in S. churro sp. nov. (Fig. 54 a) and large and spatulate in S. catarina sp. nov. (Fig. 53 a) and S. patamon (Fig. 55 a). Among numerous other differences, the vesica bears a large, central, echinate patch of several hundred small cornuti, and two, large, apical spinose cornuti in S. churro (Fig. 54 b); about eight large spinose cornuti linearly decreasing in size in S. catarina (Fig. 53 b); and a single, large, spinose cornutus adjacent to a large patch of several hundred filamentous cornuti in S. patamon (Fig. 55 b). With dissection, males of these species cannot be confused.	en	Matson, Tanner A. (2023): A review of Mexican Stamnodes (Lepidoptera: Geometridae) with the description of 16 new species.

03CEA05334727877FDCDB640AE29F85B.taxon	etymology	Etymology The specific epithet, churro, is named after the popular, fried dough dessert of Mexico and elsewhere. This name was proposed by a passionate group of fourth-grade students from Mrs Stephanie Ball’s 2021 – 2022 science class in Alexandria, Virginia. The diagnostic cream-coloured hindwing underside, generously speckled with light brown scales, was reminiscent of the colour and texture of the iconic dessert for which this moth is now named. The name is a noun in apposition.	en	Matson, Tanner A. (2023): A review of Mexican Stamnodes (Lepidoptera: Geometridae) with the description of 16 new species.

03CEA05334707878FDEDB56BAEEDFDC8.taxon	diagnosis	Diagnosis At the CNIN, Stamnodes ferropulvisa sp. nov. was sorted with S. agapetica, but it can be easily distinguished from the latter by its lighter ground colour which leans more toward a cream shade rather than orange-brown. Moreover, S. ferropulvisa lacks a strong transverse medial band on the hindwing underside, which is present in S. agapetica. Stamnodes ferropulvisa is also visually similar and presumably closely related to S. calcarea sp. nov. While both species share a tan to cream ground colour, the forewing underside apical area and hindwing underside of S. ferropulvisa is given much more toward rusty-brown than the lighter beige colour found in examined material of S. calcarea. Additionally, S. calcarea has an apparent pale, medial, transverse band on the hindwing underside that is absent or inconspicuous in S. ferropulvisa. Male genitalia of these species are quite similar, but the posterior juxtal processes of S. calcarea are more rounded apically and less deeply cleft between (see arrow, Fig. 57 a), while the same processes of S. ferropulvisa are apically pointed and deeply cleft between (see arrow, Fig. 56 a). Stamnodes ferropulvisa sp. nov. is somewhat reminiscent of S. ululata (Fig. 28), a California (USA) endemic. Both share a creamy upperside and a much darker, rust-coloured, forewing-underside, apical area and hindwing underside. Stamnodes ferropulvisa is noticeably smaller than S. ululata and lacks the bipectinate male antennae, but more importantly these species are allopatric.	en	Matson, Tanner A.

03CEA05334707878FDEDB56BAEEDFDC8.taxon	biology_ecology	Biology The flight of Stamnodes ferropulvisa sp. nov. is at least partially synchronous with S. aumatlapalli sp. nov. at the type locality in Hidalgo, and synchronous with S. saltillo sp. nov. and S. favilla sp. nov. at the type locality in Coahuila. The immature stages of this taxon remain unknown, but with new phylogenetic information and an expanded knowledge of Stamnodini life history (Matson & Wagner in prep.), the discovery of this caterpillar should be relatively easy to auger. A preliminary phylogeny of Stamnodini (Matson & Wagner in prep.) places S. ferropulvisa sister to S. formosata and deep within a clade of Cercocarpus specialists. Local Cercocarpus from the collection localities of S. ferropulvisa will likely host the larva. Likewise, the larva is likely to be stout, green to brown in colour, with 4 – 5 deep creases per segment, and abundantly salted with white excrescences. Adults may be bi- or multivoltine as confirmed records are from April through June and September. Presumably, larvae follow the adult flight in the same manner as close relatives.	en	Matson, Tanner A.

03CEA053347E787BFDC7B613AF2FF942.taxon	diagnosis	Diagnosis Stamnodes calcarea sp. nov. is visually similar and presumably closely related to S. ferropulvisa sp. nov. While both species share a tan to cream ground colour, the forewing underside apical area and hindwing underside of S. ferropulvisa is given much more toward rusty brown than the lighter beige colour found in the four specimens of S. calcarea available for examination. Additionally, S. calcarea has an apparent pale medial transverse band on the hindwing underside that is absent or inconspicuous in S. ferropulvisa. Male genitalia of these species are exceedingly similar; however, the posterior juxtal processes of S. calcarea are more rounded apically and less deeply cleft between (see arrow, Fig. 57 a), while the same processes of S. ferropulvisa are apically pointed and deeply cleft between (see arrow, Fig. 56 a). Though both species share a single spinose cornutus and an opposite echinate field of many smaller cornuti, the smaller cornuti of S. calcarea are generally half the length of those of S. ferropulvisa.	en	Matson, Tanner A.

Based on the predicted host of this moth, the dry bajada habitat where the GPS coordinates from the type specimens’ labels plot does not seem like a suitable location. Additionally, the elevation of 1810 m on the label does not match the elevation of 1140 m where the GPS coordinates on the label plot. Given this incongruence, it is likely that the labeled elevation is correct, and the given GPS coordinates should be considered only as a very rough regional approximation.	en	Matson, Tanner A.

03CEA053347D787AFDE5B284AF84F965.taxon	discussion	Taxonomic act Stamnodes similis syn. nov. is newly regarded as a synonym of S. ululata. In the original description of S. similis, Wright describes this taxon as most closely resembling S. apollo and makes no mention of S. ululata. It is unlikely Wright compared the holotype female of S. ululata to his S. similis material, for had he done so, at the very least he would have had to mention their uncanny similarity. COI barcodes and genitalic preparations of S. similis specimens at the USNM are identical to those of S. ululata. Doug Ferguson in Furniss et al. (1988) entertained this taxonomic change but did not make an explicit call for synonymy.	en	Matson, Tanner A.

03CEA053347D787AFDE5B284AF84F965.taxon	diagnosis	Diagnostic remarks Stamnodes ululata is one of only a few species of Stamnodes known to be sexually dimorphic. The male antennae are bipectinate with ciliated rami; those of the female are filiform. In males, the forewing apex, costa, and costomedial subquadrangular patch are darkened with brown-grey scales, while in females, these areas are much lighter and given towards clay. The female hindwing underside is also nearly immaculate, and only occasionally shows a very slight, medial, transverse colour transition.	en	Matson, Tanner A.

While S. seiferti extends from the northern Sierra Madre Occidental to central Arizona, northern New Mexico, and the Trans-Pecos region of Texas (USA), all known specimens of S. tenebrosa are from the mountainous Northern Oaxaca Highlands and Oaxaca’s Sierra Madre del Sur. Stamnodes seiferti is lighter in colour and slightly smaller than S. tenebrosa, and while sharing many of the same pattern elements, S. seiferti can be differentiated by the absence of a pale, arcing, medial, transverse band on a darkened hindwing upperside; in S. seiferti, the hindwing upperside is lighter, given toward dull yellow, and lacking a defined transverse band. Male genitalia are exceedingly similar; however, the laterodistal shoulders of the shield-shaped juxta are acuminate or pointed in S. seiferti and more rounded in S. tenebrosa, and although some cornuti are increasingly tiny and difficult to visualize, S. seiferti appears to have around 7 – 8 spinose cornuti, while Stamnodes tenebrosa appears to have around 5 – 6.	en	Matson, Tanner A.

03CEA05334077800FDDEB56BAE29FA70.taxon	diagnosis	Diagnosis Stamnodes tenebrosa sp. nov. is very similar to S. seiferti (Fig. 34), but so far as known the two species are allopatric. Known specimens of S. tenebrosa are from the mountainous Northern Oaxaca Highlands and Oaxaca’s Sierra Madre del Sur, while S. seiferti is a northern Sierra Madre Occidental entity that extends into central Arizona, northern New Mexico, and the Trans-Pecos region of Texas. Stamnodes tenebrosa is darker and slightly larger than S. seiferti, and while sharing many of the same pattern elements, S. tenebrosa can be differentiated by its pale, arcing, medial, transverse band on the darkened hindwing upperside; in S. seiferti, the hindwing upperside is lighter, given toward dull yellow, and lacks a well-differentiated transverse band. Male genitalia are exceedingly close to those of S. seiferti; a notable difference is the rounded laterodistal shoulders of the shield-shaped juxta in S. tenebrosa and more pointed or acuminate shoulders in S. seiferti. Stamnodes tenebrosa also appears to have around 5 – 6 spinose cornuti while S. seiferti has around 7 – 8; however, some of the cornuti are increasingly tiny and difficult to visualize and these counts should be considered with caution.	en	Matson, Tanner A.

Larvae directly follow the adult flight and feed on new growth in the early spring. David L. Wagner and I recently collected the first larval record of Stamnodes reckseckeri in southern California from white sage, Salvia apiana (Lamiaceae). The larva is to our eyes indistinguishable from sister species S. affiliata, and worse, the two are sympatric, synchronic, and share Salvia as a host. So far as known, molecular identification will be required to disambiguate the immature stages of these related taxa. Although our single record was from white sage, it is possible that S. reckseckeri also feeds on black sage (Salvia mellifera) and other woody Salvia, as does S. affiliata.	en	Matson, Tanner A.

03CEA05334047805FDFCB342A956F814.taxon	discussion	Taxonomic act Stamnodes artemis is regarded as a new synonym of S. agapetica. Dyar’s original description of S. agapetica is weakly informative, but the types of S. artemis match in fine detail the holotype of S. agapetica. Genetic evidence further supports this new synonymy; a COI barcoded individual (BOLD Process ID: LNAUY 473 - 19; GenBank OP 898460) collected at 9000 ft in Hidalgo shows only a subtle genetic barcode divergence (~ 1 %) from Arizona’s S. artemis. Although neither the holotype nor topotypical specimens of S. agapetica have been sequenced, the sequenced specimen from Hidalgo appears to be representative – Hidalgo and the type locality of Zacualpan are quite close. Rindge (1958) was probably unaware of S. agapetica when he described S. artemis, as it was classified in Coenocalpe Hübner and no prior work had consolidated the many Stamnodes species that were at that time spread across a few disparate genera.	en	Matson, Tanner A.

03CEA05334027804FD9CB56BA882FA5D.taxon	diagnosis	Diagnostic remarks In the USA, this taxon may be difficult to distinguish from closely related congeners, especially at the northern end of its range in California. In Mexico, however, this species cannot be confused with other members of the genus.	en	Matson, Tanner A.

03CEA05334027804FD9CB56BA882FA5D.taxon	distribution	Distribution Mexico: Stamnodes albiapicata is found in the chaparral associations, canyons, and Pacific coastal scrub communities of Baja California. Records extend well into the Baja California Desert as far south as El Rosario. So far as known, no moths have been taken from Sonora, though it is recorded a short distance away in Pima Co., Arizona (USA). USA: Stamnodes albiapicata ranges from Southern California to just south of the Bay Area, and east to central Arizona.	en	Matson, Tanner A.

03CEA05334027804FD9CB56BA882FA5D.taxon	biology_ecology	Biology There is a single winter flight from December through February with a few individuals persisting into March. Larvae directly follow the adult flight and are found on new foliage in the spring. McFarland (1965) lists various hydrophylloid Boraginaceae as the hosts of this species, including Phacelia Juss., Pholistoma Lilja, and Nemophila Nutt. David L. Wagner and I have collected larvae (Fig. 90) from both Phacelia and Pholistoma in California. Additional unpublished life history details and larval illustrations are forthcoming (Matson & Wagner in prep.).	en	Matson, Tanner A.
