187787BA43522B3E40B3FA290F1DF823.taxon	discussion	Comments. Prionopelta mocsaryi Forel, 1907, was excluded from this revision. It was described from a specimen putatively from Paraguay but it is actually a mislabeled specimen of Prionopelta opaca Emery, 1897, a Melanesian species (Wilson 1958; Brown 1960). Prionopelta mocsaryi is currently a junior synonym of P. opaca (Bolton 2020). We confirmed the synonymy through the examination of images of the relevant types at AntWeb. org. Workers and queens of the Neotropical species always have a well-impressed metanotal groove and 11 or 12 antennomeres, while some Old World species can have the metanotal groove indistinct, and fewer than 11 antennomeres (Brown 1960; Arias-Penna 2008; Fernández et al. 2019). The worker caste shares a small body size; punctulate, punctate or foveolate sculpturing that is more conspicuous on the head dorsum; erect setae; abundant pubescence; a small genal tooth; and a reduced compound eye. The carinate surface of each tooth-like clypeal seta is clearly noticeable in the images available for the specimen ANTWEB 1008581 in AntWeb. org. A detailed morphological description of the larvae was provided by Wheeler & Wheeler (1952), based on five larvae and two “ semipupae ” from Colombia. The authors identified the specimens as P. punctulata, but we suspect they were misidentified and could have been specimens of Prionopelta antillana. We were not able to locate these specimens.	en	Ladino, Natalia, Feitosa, Rodrigo M.

187787BA435D2B2F40B3F8D10ECFFAE3.taxon	discussion	Comments. The limits between P. antillana and P. amabilis have been one of the main taxonomic problems of the genus in the Neotropics, given their morphological similarity and sympatric distribution. South American specimens of P. amabilis have been historically considered probable morphological variations of P. antillana. In Central America, material corresponding to our new species P. dubia sp. n. has been routinely misidentified as P. amabilis or P. antillana. Here, the differences among the species are finally clarified, mainly in terms of density of pubescence and sculpturing, shape of clypeus, comparative length between the median and basal tooth of the mandible, and convergence of the subpetiolar process margins. In P. amabilis, the pubescence is sparse, the sculpture is shallow, the anterior clypeal margin is slightly projecting medially (somewhat triangular), the median tooth of the mandible is distinctly shorter than the basal tooth, and the margins of the subpetiolar process are parallel or subparallel. Prionopelta dubia sp. n has dense pubescence, the sculpture is shallow, the anterior clypeal margin is evenly rounded, the lengths of the median and basal teeth of mandible are similar, and the margins of the subpetiolar process are subparallel or parallel. Prionopelta antillana has the anterior clypeal margin slightly projecting medially, the median tooth of the mandible is distinctly shorter than the basal tooth, and the margins of the subpetiolar process are apically convergent. Natural history. The species is mainly known from litter samples collected in tropical forests; reported at elevations of 50 – 960 m. They nest in rotting logs and colonies may have large numbers of workers. Hölldobler & Wilson (1986) and Hölldobler et al. (1992) observed captive colonies collected during the dry season in well-developed secondary rainforest of Costa Rica. In the 1986 study, the authors censused and excavated colonies, observed the behavior of the ants and conducted a “ cafeteria ” experiment to study dietary choice, which consisted in offering living arthropods from leaf litter and rotting wood from the sites nearby original Prionopelta nests to the captive ants. Two large colonies were carefully excavated. The total population of the first colony was: one queen swollen with eggs, 709 workers, between 100 and 200 eggs, 82 larvae and 126 pupae; with the emergence of alate queens from the cocoons two days after the capture of the colony. The second population counted: a dealate queen, 282 workers, 100 eggs, 76 larvae and 264 pupae. Authors considered that the colonies are both monogynous and polydomous, discrete and kept apart by nestmate recognition. Cafeteria trials suggested a preference for campodeid diplurans as prey. The authors offered land snails, isopods, spiders, ricinuleans, mites, phalangids, pseudoscorpions, geophilomorph centipedes, millipedes, pauropods, campodeid and japygid diplurans, lepismatid and machilid thysanurans, entomobryomorph collembolans, kalotermitid and nasutermitine termite nymphs and workers, zorapteran nymphs and adults, hemipteran, tettigonid, earwig and gryllid nymphs as well as larvae and adults of ants and beetles. Prionopelta amabilis was capable of kill most of the groups cited above in two or three minutes, only ignoring the snails, spiders, phalangids, ricinuleans and millipedes. They affirm that the species has a rudimentary but well-marked division of labor based on age, correlated in turn with early rise in ovarian development and a decline as the workers turn increasingly to foraging. Also, the authors divided the workers in three classes based in age and the increasing of body pigmentation: light callow, medium callow and fully pigmented. Additionally, they provided interesting notes regarding grooming, trophallaxis, trophic eggs, brood care, alarm and what is called the phenomena of “ wall-papering ” and “ foot-dragging ”. The grooming among workers and self-grooming was less frequent than from workers to queen. No evidence of adult transport nor trophallaxis was found. Workers can have well-developed eggs and older workers frequently offered eggs to the queen, with no report of she feeding from any other manner. Workers were observed segregating eggs, small larvae, large larvae and pupae into separate piles; complementarily to this, the authors observed a “ wallpapering ” phenomenon, where they inferred that cocoon layers present in the walls of the galleries housing pupae served to keep them from growing to moist, contrary to the galleries occupied by the queen, eggs, larvae and resting group of workers. Workers rapidly responded to air currents and sudden illumination with a body vibration, also observed in the first approach to the queen and sometimes between workers, but the authors did not find any alarm pheromone. Nevertheless, when the workers were placed in a strange surface, they observed that the ant extended the legs backwards and dragged the tarsi for short intervals. This “ foot-dragging ” phenomenon was thought to be probably associated with trail laying or home range. In the 1992 study, the “ foot-dragging ” phenomenon was further explored. One large colony was collected, containing two queens with active ovaries and filled spermatheca, more than 500 workers and many larvae and pupae. Complementing the behavior associated with the phenomenon described above, a rapid vertical shaking of the body performed by the workers was frequently observed. Observations of the ants’ behavior as well as histology of front, middle and hindlegs were made, and the findings suggested that P. amabilis employ recruitment communication, somewhat associated with the “ foot-dragging ” phenomenon and the body shaking. The authors reported the presence of basitarsal glands in the hindlegs of workers and queens of the species, and demonstrate that their secretions are employed during recruitment to food sources and to new nesting sites; this is made during the perform of mechanical signals cited above, which apparently stimulates the nestmates to follow the trail. Prionopelta amabilis workers have been seen “ walking under the fungus garden of Apterostigma sp., in the ground under a large rotten log ” (Lívia Pires do Prado pers. comm., # LPP _ 303).

187787BA43452B2240B3FA0D0EF8F8B3.taxon	discussion	Comments. Forel (1909) presented the first key for the identification of the Neotropical species of Prionopelta. In this key, P. marthae and P. punctulata subsp. antillana appear in the same couplet, with some ambiguous characteristics separating both species. Almost 50 years after its description, P. marthae was considered a junior synonym of Typhlomyrmex rogenhoferi Mayr, 1862 (Brown 1953), based on a Typhlomyrmex specimen mislabeled as syntype of P. marthae located in the collection of William M. Wheeler (MCZ). In consequence, the species was excluded from the key provided by Brown (1960). Later, the species was recognized as a member of Prionopelta, close related to P. antillana, and was transferred to this genus by Brown (1965). The examination of type specimens revealed that the bottom specimen mounted on the pin that holds syntypes of P. marthae deposited at NHMB belongs to the myrmicine genus Solenopsis. Also, the “ cotype ” specimen deposited in MCZ under the code MCZ-ENT 00020384 belongs to the ectatommine genus Typhlomyrmex. Initially, subtle differences seemed to separate P. antillana and P. marthae, according to the original descriptions and among specimens accumulated in scientific collections, specifically regarding the head dorsum sculpturing, the shape of the subpetiolar process and the width of the first gastral segment. In fact, type specimens of P. marthae and P. antillana show morphological differences (CASENT 0102526, CASENT 0902630, CASENT 0102529 and MCZENT 20385). However, both forms are highly overlapped in their wide distribution, and the morphology follows a continuous variation that blurs the limits between the species. This was supported by the analysis of the measurements that showed a very close relationship between the individuals, in terms of variation and discrimination of groups (Fig. 36 A, B). Still, we saw that some specimens of São Paulo, Paraná and Santa Catarina, Brazil, show a denser sculpturing on the head dorsum and different degrees of convergence between the margins of the subpetiolar process, features not considered in the statistical analysis. Considering the statements above, we synonymized P. marthae with P. antillana. Also, we believe that P. antillana still may harbor a complex of cryptic species difficult to resolve with morphology alone. Dr. James Wetterer (pers. comm.) made a great effort to illuminate the geographic spread of P. antillana. The following account is based on Dr. Wetterer’s notes on published and unpublished records of the species: “ P. antillana is a tiny ant with records from the West Indies, South America, Central America and subtropical central Florida […] I have collected the species at 48 sites on the West Indian Islands of Grenada (2), Guadeloupe (2), Martinique (5), Montserrat (4), Nevis (8), St. Kitts (8), St. Lucia (3), St. Vincent (8), and Trinidad (8). The islands of Grenada, Montserrat, Nevis, St. Kitts and St. Lucia have not reported the presence of the species so far […]. There is a difficulty in the distinction of P. antillana and P. amabilis, and then a probability of misidentification between both species in the records […]. Although Brown (1960) considered that the species was introduced to the Lesser Antilles, recent collecting have much filled the distributional gap. The current distribution of P. antillana is now understood considering the natural spread through short-distance island-hopping. ” Part of the specimen records cited by Dr. Wetterer were confirmed in our work, and some of the unconfirmed ones follow the distribution of the species presented here (Fig. 35 B). Nevertheless, our work only considers material examined directly by us or through high resolution images. Forel (1893) provided the description of a male specimen said to be P. punctulata collected at St. Vincent by Mons. H. H. Smith, as well as field annotations from the latter author. As insightfully noted by Dr. Flavia Esteves (pers. comm.) and in line with the distributions recognized here for P. punctulata and P. antillana, the male described by Forel actually belongs to P. antillana. Natural history. The species is mainly known from pitfall traps and leaf litter samples collected in tropical forests. It is reported at elevations of 200 - 1010 m. Field annotations provided by Mons. H. H. Smith of specimens from St. Vincent under the name of P. punctulata are presented in Forel (1893). We summarize this information as follows: somewhat common and sluggish ants, generally found in shady and damp places, sharing the substrate with other ants. Differences between workers and queens do not seem to be very obvious. Deyrup et al. (2000) reported that the species may be introduced from the Lesser Antilles or Central America to the state of Florida, USA, where it is “ common in rotten wood in parts of Marion and Sumter County ”. The following account is based on the detailed observations of Deyrup et al. (2016) about the presence of P. antillana in Florida: the worker caste of the species is small and cryptic, collected in soil, under low evergreen scrub oaks, in mesic hammocks, sand pine scrub and leaf litter samples; known from a 2004 expedition near the Big Scrub Campground in Ocala National Forest and during the Florida ant survey. This species is the unique record of the genus in the United States, probably imported to Marion County from West Indies, it spread slowly ever since, and eventually should occupy southern Florida. The city of Silver Spring and a botanical garden located there might be the entering site for the introduction of the species, since famous films supposedly set in the tropics were filmed there, like 1930 s Tarzan movies with Johnny Wissmuller, in which aquatic adventures in Silver Springs are jarringly intermixed with odd footage from Africa and elsewhere. Perhaps tropical plants were brought for some scenes. These last statements about the origin of the species introduction in Florida were also noticed by Dr. Andrea Lucky (pers. comm.) and discussed.

The name refers to the authors’ doubts regarding the identity of this species in several stages of this work, and its historical misinterpretation in scientific collections and repositories, where the individuals have been mainly confused with P. amabilis. From Latin dubium = doubt.	en	Ladino, Natalia, Feitosa, Rodrigo M. (2020): Taxonomic revision of the genus Prionopelta Mayr, 1866 (Formicidae: Amblyoponinae) for the Neotropical region.

187787BA43482B2440B3F8A80884FACF.taxon	discussion	Comments. Besides its diagnostic characters, the species is recognized by its abundant pilosity. This species is commonly confused with P. amabilis. This may be related to the fact that the holotype of P. amabilis had not been photographed nor deposited in an open database of images. These issues were resolved at the end of 2019. Despite a thorough description of P. amabilis by Borgmeier (1949), Prionopelta comprises ants with subtle differences among its species, and consequently, the probability of misinterpretation is greater. Here, we were able to establish the true identify of P. amabilis and to recognize differences between it and P. dubia. Prionopelta dubia and P. amabilis are broadly sympatric. They are similar in being shallowly punctate on the head dorsum and having a broad subpetiolar process. Prionopelta dubia has more closely-spaced puncta, the clypeus is evenly rounded, and the basal and median tooth of mandible tend to be similar in length. Prionopelta amabilis has more widely-spaced puncta, the clypeus slightly projecting medially, and the basal tooth of the mandible is distinctly larger than the median tooth. In Central America and some localities of Peru, Ecuador and Bolivia, P. dubia may be more conspicuously pubescent and posterior portions of the head may be more infuscated. These traits are gradually less visible in specimens occurring through southern Central American countries and almost imperceptible in the specimens from the remaining countries of South America. Natural history. The species is mainly known from litter samples collected in tropical forests. It is reported at elevations of 50 – 1500 m. Longino (unpublished notes available on AntWeb. org) observed pleometrotic colony founding, with pairs of queens in small chambers under rotting bark. Field notes by Lívia Pires do Prado and Rogério Rosa da Silva (# LPP _ 304), suggest that workers move very slowly and that the colonies inhabit fallen logs with a high degree of decomposition.

187787BA434E2B1A40B3FA61088AFF4F.taxon	etymology	Etymology. The species is named in honor of Maria Escolástica da Conceição Nazaré, also known as “ Mãe Menininha do Gantois ”, a descendant of the Nigerian Yoruba royalty enslaved in Brazil, and one of the most prominent Brazilian iyalorixá (spiritual leader of the Afro-Brazilian religion Candomblé). The species name is a recognition to the Afro-Brazilian religions and community, and to the state of Bahia, from where P. menininha is mainly known. The specific epithet is a Portuguese noun in apposition, indeclinable in accordance to articles 31.2.1 and 31.2.3 of the International Code of Zoological Nomenclature.	en	Ladino, Natalia, Feitosa, Rodrigo M.

187787BA434E2B1A40B3FA61088AFF4F.taxon	discussion	Comments. This species can be confused with P. punctulata and P. tapatia because of the presence of eleven antennomeres. However, morphological features allow the separation of these three species. Prionopelta punctulata has the clypeus strongly projecting medially and the subpetiolar process with margins apically convergent, in contrast to P. menininha. It can be distinguished from P. tapatia mainly by the obtuse posteroventral angle of the subpetiolar process, acute in P. tapatia. Also, P. menininha has the petiolar node and the first gastral segment wider and longer than P. tapatia. Finally, so far, P. tapatia is a species endemic to Mexico. Natural history. Most specimens are known from pitfall and soil samples collected in dry forest areas. Additional material examined (5 specimens). BRAZIL: Bahia: Itaberaba, Faz.

187787BA43702B1840B3FEDC0DB3FB09.taxon	discussion	Comments. This species can be confused with P. modesta since both have a dense foveolate sculpturing on the head dorsum and twelve antennomeres. Comparatively, P. modesta comprises larger ants, with interspaces between fovea of the lateral portion of frons moderately spaced and posterior margin of the subpetiolar process clearly concave. Prionopelta minuta groups smaller ants, with nearly confluent foveolate sculpturing and posterior margin of the subpetiolar process straighter. The last feature mentioned for P. minuta is useful to separate the species from other Neotropical members of the genus, as well as the body length of workers, always lesser than 1.40 mm. Most of the specimens known so far for P. minuta come from the Amazon rainforests of the Brazilian states of Rondônia and Amazonas. The transitional areas between these forests and the Brazilian savanna (Cerrado) are extremely fire-sensitive, and anthropogenic activities related with deforestation for crop and livestock establishment as well as global warming have shown negative effects on their biodiversity (Pivello 2009; Shlisky et al. 2009; Silveira et al. 2013). Intriguingly, the species has been recorded in the lowlands of the central and meridional Brazilian Amazon and in the western slopes of the Andean mountain range, Colombia. Although we cannot presently discard the possibility that this species is widely distributed in the western Amazon realm, further collection records are required to confirm the disjunct distribution of P. minuta. Natural history. The species is mainly known from leaf litter and dead wood samples collected in well preserved forests; reported at elevations of 152 - 1430 m.

187787BA43722B1C40B3FB110E8EFE37.taxon	discussion	Comments. The species was commonly considered as the only Neotropical Prionopelta with dense sculpturing on the head dorsum, giving the appearance of an opaque integument. Although this trait can be currently used to separate P. modesta from the other species occurring in Central America, the densest and deepest sculpturing on head dorsum of all the Neotropical species described in this work belongs to P. minuta, from which P. modesta can be separated by the larger body size and the concave posterior margin of the subpetiolar process. Prionopelta modesta is mostly distributed through Central America. Hence, the isolated records of the species in Guyana and Colombia are unexpected. We have examined a considerable number of Prionopelta specimens from Panama and Venezuela and we were not able to recognize any P. modesta individuals in these samples. At the same time, the P. modesta specimens from Guyana and Colombia, examined here, fit with the species diagnosis. Thus, further collection records would be useful to better understand the distribution pattern of the species. Natural history. The species is mainly known from litter and dead wood samples collected in tropical forests; reported at elevations of 50 - 1840 m. According to observations available in Brown (1960) about several colonies of P. modesta collected at Pueblo Nuevo, Veracruz, Mexico, colonies appear to be split into sections and occupy bits of rotting wood or bark in the leaf litter. The individuals found in these fragments (workers or workers and larvae) could indicate a low level of organization or that the ants could be more or less nomadic. In a “ cafeteria ” experiment, several live and dead arthropods were offered, but, overall, just a timid response on the workers’ part was observed, with individuals mostly recoiling violently when their antennae came into contact with the potential prey. On the other hand, some specimens were capable of biting, hanging onto, and stinging into immobility somewhat large arthropods. Still, based on these observations, the usual prey may include small centipedes or symphylans, but further examination of nests needs to be done to determine what Prionopelta feeds upon. Additional material examined (56 specimens). COLOMBIA: Meta: Transecto Sumapaz, 3.8666667 - 74.416664, 1120 m, 09. viii. 1981, T. van der Hammen col., SUM 29, CASENT 0260467 (1 worker) [PSWC].

187787BA43762B1040B3FE390D7AFA07.taxon	discussion	Comments. The species is easily distinguished from other Neotropical Prionopelta by its diagnostic characteristics. Prior to this study, Prionopelta punctulata was the only Neotropical species of the genus with 11 antennomeres. Here, we described two new species with the same antennal count. Prionopelta punctulata can be easily separated from P. menininha and P. tapatia by the very marked medial projection of the anterior clypeal margin, the finer sculpture of the head dorsum, and the margins of the subpetiolar process converging apically. The description of the genus is based on the characteristics of the queen, collected in southern Brazil (Paraná) and described by Mayr (1866) as P. punctulata (Fig. 29). The first worker was found in Santa Catarina, and after its description, the specimen was associated with the P. punctulata queen by Mayr (1887). Forel (1909) considered the worker to be a distinct species, which he named Prionopelta mayri. Prionopelta bruchi, from Argentina, was subsequently described by Santschi (1923). Brown (1960) synonymized these last two names under P. punctulata arguing that the differences between them were negligible, probably due to a different viewing angle, interpretation, and allometric variation. We concur with Brown’s synonymy. The distribution of Prionopelta punctulata is mostly centered in southern Brazil and northwestern Argentina. However, there are a few isolated records in the Brazilian central state of Goiás, in Bahia and Piauí in the northeast (Jory & Feitosa, 2020). However, the most peculiar record for the species is from the Central Amazon, in northern Brazil. Despite these isolated records, the specimens from all series can be perfectly recognized as P. punctulata. Natural history. Little is known of its biology. The species is mainly known from litter samples collected in tropical forests; reported at elevations of 170 - 876 m. Additional material examined (286 s pecimens).

187787BA437A2B1740B3FA260EDFF823.taxon	discussion	Comments. Among the Neotropical Prionopelta with eleven antennomeres, this species is different from P. punctulata by the shape of clypeus and the basal margins of mandibles and from P. menininha by the presence of a discrete projection of the cuticle in the posteroventral angle of the subpetiolar process. One worker showed ocellar vestiges. Natural history. The species is mainly known from leaf litter samples collected in disturbed areas, at elevations greater than 900 m.
