03CF652B381DFFA4FF5BBF10FE58A5EC.taxon	discussion	Remarks. The coloration of Ennya species is usually yellowish green, but also varies from brown, orange, yellow, white or black; with black patches or bands, the central carina contrasting black (Figs. 1 C – D) or concolorous with the pronotum. Some species present remarkable sexual dimorphism in coloration and shape of dorsal process with females frequently lighter and with a higher dorsal process than males. The shape of the dorsal process is likely the most important character to distinguish species, although the elevation may vary within the same species. Species with a trapezoidal dorsal process present an anterior and posterior vertex (Fig. 1 A), and the shape can vary independently of each vertex from rounded to triangular. The orientation (forwards, upwards or backwards) of the dorsal process apex (or anterior vertex in trapezoidal process) may be used to delimit species. Currently, E. colombiana Sakakibara, 1996 a is the only known species that lacks a dorsal process. The pronotum reaches nearly to, or slightly beyond, the forewings tips except for E. allkukiru sp. nov., in which the pronotum barely reaches the apex of the third apical cell (Fig. 2 B). The metopidium, in frontal view, is usually rounded except for E. lamariela sp. nov. which is sub-quadrate (Fig. 7 A).

03CF652B381CFFA0FF5BBAACFAECA474.taxon	discussion	Remarks. This is the first known species of the genus Ennya in which the apex of the pronotum does not surpass the apex of the forewing third apical cell. The apex of the pronotum in Ennya usually reaches or slightly surpasses the apex of the forewing. Ennya allkukiru sp. nov. is most similar to E. conica (Fairmaire, 1846) by the triangular acute dorsal process with transversal carinae and the concolorous median carina. However, the pronotum of E. allkukiru sp. nov. does not reach the forewing apex and the posterior margin of the dorsal process is not continuous with the posterior margin of the dorsal process, forming an obtuse angle. E. allkukiru sp. nov. differs from E. sobria (Walker, 1851) and E. dorsalis (Fairmaire, 1846) in having the median carina concolorous rather than black, and from E. scaramozzinoi Creão-Duarte & Sakakibara, 1994 in having the apex of the dorsal process not directed upwards but backwards. The acute triangular dorsal process of E. allkukiru sp. nov. differs from those of E. andina (Sakakibara, 1996 a), E. conspersa, E. pacifica (Fairmaire, 1846), E. bordoni Sakakibara 1996 a, E. notata, E. nutans, E. lamariela sp. nov., E. ecuadoriensis, E. gibbera reinst. comb., and E. maculicornis (Fairmaire, 1846) in being distinctly acute rather than blunt.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

The head and pronotum were accidentally separated from the body during genitalia dissection, then glued together using Shellac Gel. Natural history. Ennya allkukiru sp. nov. inhabits the remnants of Oriental Montane Forest of the North Andes, in a zone fragmented by livestock pastures (Fig. 9 B). The specimen was found solitary perched on the branch of an undetermined plant 170 cm above the ground. Species of Ennya are subsocial (Godoy et al. 2006) but solitary adults can be found on a variety of plants, perhaps searching for acceptable hosts.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

03CF652B3818FFAEFF5BBEA0FD0AA26E.taxon	discussion	Comments: Ennya chlorizans and E. nebulosa were transferred to Gelastogonia Kirkaldy 1904 by Funkhouser (1951), and then both were synonymized under E. chrysura by Metcalf & Wade (1965). More recently, Sakakibara (1996 a) considered E. chlorizans and E. nebulosa as junior synonyms of E. rufomaculata but the latter does not belong to the genus Ennya (see below). Ennya chlorizans and E. nebulosa do not belong to Gelastogonia because they lack reticulated pronotal carinae (Sakakibara, 1996 a). Ennya chlorizans and E. nebulosa are the same species, their primary types representing opposite genders, which may explain the color variation and the small differences in pronotal shape. Such sexual dimorphism has been observed in additional material examined. Moreover, both type specimens were collected in the same location and Ennya chlorizans and E. nebulosa were described in the same manuscript. Following the principle of the first revisor (International Code of Zoological Nomenlature Art. 24.2), we select E. chlorizans to have precedence. Ennya chlorizans is easily recognizable by the pronotum having the dorsal process trapezoidal, longer than high, with the anterior margin concave with an acute triangular vertex slightly directed backwards, and the posterior margin rounded. It is most similar to E. chrysura but can be distinguished by the uniformly concave anterior margin of the dorsal process which is also not as elevated. This species is sexually dimorphic in coloration and the shape of the pronotum. Females are mainly yellow with a discontinuous black band and black spots while males are predominantly black. The anterior margin of the dorsal process in females is more concave than in males.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

03CF652B3817FFAEFF5BBD74FB89A5E8.taxon	discussion	Comments: Ennya conspersa was synonymized with E. dorsalis by Funkhouser (1927) but later revalidated by Sakakibara (1996 a). Ennya conspersa differs from E. dorsalis in having a blunt dorsal process with the central carina concolorous to the pronotum, compared to acute and contrastingly black, respectively, in the latter. The pronotal shape of E. conspersa resembles that of E. notata (Figs. 4 D – E) and the coloration is the only remarkable difference. The pattern of coloration in both species seems to be conserved in the paralectotypes. Stål (1869) agreed they are very similar and only differ in the coloration and the dorsal process of E. notata Stål being inclined slightly forward compared to sub-perpendicular in E. conspersa Stål. However, this last difference is not very distinctive. According to the specimen labels, the type locality of both species is “ Bogotá ” but in the 19 th century that city served as a place for shipping specimens to Europe, so it is unknown if the specimens were collected at the same place (Forero 2006). Further study of additional type material and other specimens of these species is needed to clarify their status. Sakakibara (1996 a: Figs. 7 and 8) examined two specimens of opposite genders that he identified as E. conspersa. However, they differ distinctly from the type of E. conspersa in lacking a dorsal process and likely represent a species not yet described. Those individuals are clearly different from E. conspersa.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

Sakakibara (1996 a) revalidated the species, arguing that the type localities of both are too distant from each other for them to be considered the same species. The specimen that Sakakibara (1996 a) illustrated and identified as E. ecuadorensis likely is misidentified due to the differences in the shape of the dorsal process, which is larger and inclined forwards in Sakakibara’s specimen. Ennya ecuadorensis resembles E. conspersa but differs in the uniform fuscous coloration, thinner dorsal process, slightly more produced humeral angles and amber forewings.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

03CF652B3814FFA8FF5BBB51FE60A61E.taxon	discussion	Remarks. This is the first known species of the genus Ennya in which the shape of the metopidium in frontal view is sub-quadrate; the other species exhibit a rounded shape. Ennya lamariela sp. nov. is most similar to E. andina with the triangular dorsal process being short, blunt and directed upwards. However, the pronotum of E. lamariela sp. nov. has a second elevation not produced next to the dorsal process while, in E. andina, after the dorsal process the pronotum descends gradually to the apex. Ennya lamariela sp. nov. differs from E. pacifica, E. bordoni, E. notata, E. nutans, and E. gibbera reinst. comb. in having the anterior margin of the dorsal process not sub-perpendicular but oblique. The triangular dorsal process directed upwards in E. lamariela sp. nov. separates it from E. ecuadoriensis, E. conspersa, and E. maculicornis, which all have a dorsal process that is directed forward. The blunt dorsal process of E. lamariela sp. nov. distinguishes it from E. sobria, E. conica, E. dorsalis, E. scaramozzinoi, and E. allkukiru sp. nov., which all have an acute dorsal process. Lastly, E. lamariela sp. nov. differs from E. colombiana by the presence of a dorsal process, and from E. chrysura, E. funkhouseri, and E. chlorizans in having the dorsal process triangular instead of trapezoidal.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

Seven females ZSFQ-i 11333: 11340 and three males ZSFQ-i 11341: 11343 with the same data as holotype. Additional material. Six nymphs at different stages with the same data as holotype ZSFQi 11344: 11349. Notes. Holotype and paratypes minuten-mounted, in excellent state of preservation. Holotype and one female paratype with dissected abdomens placed in vials with glycerol pinned with specimens. Natural history. Ennya lamariela sp. nov. inhabits the remnants of the mature forest of Occidental Foothill Forest of Northern Andes, in a zone extremely fragmented by banana (Musa × paradisiaca L.) monoculture and livestock (Figs. 9 C – D). Adult specimens and nymphs at different stages were found in an aggregation on the low branches at 150 cm above the ground of an undetermined species of Caesalpinioideae D. C. (Fabaceae). However, egg masses or scars were not found. The proportion of nymphs was higher than adults, as was females over males. Species of the genus Ennya in the Andes are usually found around 2,000 m (Flórez-V et al. 2015), so this record is one of the lowest known altitudes.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

03CF652B3811FFA8FF5BBB4CFED4A4D5.taxon	discussion	Comments: Ennya notata was synonymized with E. dorsalis by Funkhouser (1927, 1951), Goding (1929), transferred to the genus Gelastogonia and included Oxygonia accuminata Buckton, 1903 as junior synonym, and lastly the species status was revalidated by Sakakibara (1996 a) and transferred O. accuminata to synonymy under E. conica. The type locality is ambiguous (see comments under E. conspersa). Ennya notata differs from E. dorsalis in having a blunt dorsal process and the central carina concolorous to the pronotum instead of acute and black respectively. It closely resembles E. conspersa (check the comments of E. conspersa).	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

03CF652B3810FFA9FF5BBEA0FBFDA180.taxon	discussion	Comments: Ennya nutans was considered a synonym of E. conica by Funkhouser (1927, 1951). However, this species is significantly different: E. nutans has a blunt dorsal process directed forward while the dorsal process of E. conica is acute and directed upward. Ennya nutans resembles E. maculicornis in having an oblique dorsal process, but that process is considerably more slender in E. maculicornis than in E. nutans.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

03CF652B3810FFA9FF5BBCCEFDD0A7CD.taxon	discussion	Comments: Ennya sobria differs from all its congeners except for E. dorsalis in having a spine-like dorsal process, orange coloration and black central carina. Ennya sobria was considered a synonym of Ennya dorsalis for a long time until Sakakibara (1996 a) reviewed the types and revalidated the species; however, he did not provide any comments. Also, we could not find differences in the original description of E. dorsalis (Fairmaire, 1846). The localities reported for this species, including the type locality “ Quito ”, are not precise (Goding 1929). However, this species definitively is not found in Quito and we suggest somewhere around Papallacta could be the type locality due to its proximity to Quito (~ 50 km east). Also it has been reported from Colombia (McKamey 1998). This species is subsocial, with adults and nymphs at different stages found together, in groups of ten to 20 individuals on the same host plant.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

03CF652B3810FFB6FF5BB85BFE59A3D6.taxon	discussion	Comments: Sakakibara (1996 a) considered that C. fasciata belonged to the genus Ennya, but the complete absence of a dorsal process and the postocular lobe being sub-quadrate places it into the genus Creonus. This species is closely similar to Creonus lloydi (Funkhouser, 1914), with some discrete differences that possibly represent intraspecific variation but probably not. A revision of Creonus is needed, because there are other species (Flórez-V et al. 2015).	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.

03CF652B380FFFB6FF5BBF7DFEF7A5D6.taxon	discussion	Comments: This species was formerly described in the genus Heliria Stål, 1867 and then transferred to Telamona Fitch, 1851 (Funkhouser 1927). Later, Goding moved it to Gelastogonia (1929) and lastly it was referred to Ennya by Metcalf & Wade (1965). It does not belong to the genus Ennya based on the pronotum not concealing the forewings and the absence of carination. Instead, it presents the diagnostic characteristics of the subfamily Centronodinae Deitz, 1975 based the scutellum being concealed medially and forewing vein M with more than three branches reaching the margin (Dietrich et al. 2001). However, the species does not have reticulate venation which is frequently present in Centronodinae. It is placed in the genus Centronodus Funkhouser, 1930 based on the produced suprahumeral angles (Barreira & Sakakibara 2001). Metcalf & Wade (1965) only reported the species from Brazil, although Funkhouser (1951) also reported it from Ecuador.	en	Montalvo-Salazar, Jorge L., López-García, Margarita M.
