Type-species: Ernocornutia catopta Razowski, 1988 .
The original characterization of the genus ( Razowski, 1988) is confirmed by the present material. All known species are externally very similar, and examination of the genitalia is required for accurate identification.
Male. All species are characterized by a slender uncus, variably expanded terminally; broad, hairy socii; and a rather short gnathos with the terminal plate strongly reduced (usually very small or undifferentiated), and the termination of each arm of the gnathos in the form of a large plate or process, partially or nearly entirely minutely spined. The vinculum is complete, usually slender. The valva is slender with a well developed costa, often with a few long bristles; the distal part of the valva beyond the sacculus is short in a majority of species; the disc is hairy; the pulvinus is not developed; the sacculus is long, broad basally, and with a ventral concavity and a terminal lobe or process in many species; the end of the free termination of the sacculus bears a patch of short spines or bristles (except in E. firna ). The transtilla is simple, usually weakly sclerotized, with broader lateral portions; and the juxta is small or moderately small. The aedeagus is more or less broad, rather short, and membranous dorsoposteriorly in some species; the coecum penis is rather short; and the cornuti are in the form of a pair of short funnel-shaped sclerites and/or a group of minute thorns.
Female. The papillae anales are moderately slender, with large proximal portions; the apophyses are slen- der and short; the sterigma is rounded proximally, but occasionally is concave, with broad lateral parts, and often with a small fold on each side of the ostium; the distal part of the sterigma is membranous. The antrum is broad and rather weakly sclerotized, except for the ventromedian portion; the remaining parts of the ductus bursae are variable, broad, or at least in part slender, with one or two coils; the accessory bursa originates at the proximal part of the antrum; the ductus seminalis extends from the distal portion of the corpus bursae; and there is no signum or other sclerites.
Biology and distribution. The genus probably is restricted to higher elevation forests of Ecuador, Colombia, and Peru (undetermined species). In Ecuador, it occurs in the uppermost zone of the cloud forest and subparamo, from 3100 to 3650 m elevation. The genus occurs in both the West and East Cordillera, but no species is recorded from both mountain chains. Species collected in the East Cordillera are Ernocornutia paracatopta , E. termasiana , E. sangayana , and E. firna ; species found in the West Cordillera include E. pilaloana , E. pululahuana , and E. chiribogana .
