Ennya sobria ( Walker, 1851) ( Figs. 1C–D , 10A )

Material examined: Holotype female (DEI Hemimetabola # 100324) Hille limbispina Breddin (SDEI) . Additional material: Two females (ZSFQ-i11661:11662) and one male (ZSFQ-i12390) from ECUADOR: Napo: Papallacta, Guango Lodge .

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 (1996a) 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.
