Smicridea (Smicridea) nigricans Flint 1991

Smicridea (Smicridea) nigricans

This is another species closely related to S. (S.) curvipenis, new species, and S. (S.) grandisaccata, new species, by the derived character of the presence of apicolatcral plates on the phallus. From the latter species it may be recognized by its smaller size, and the structure of the phallus which is straight and bears differently formed internal sclerites.

ADULT.—Length of forewing, 3.5 mm. Color uniformly fuscous, forewing uniformly fuscous, with apical third angled sharply mesad Male abdomen with 2 pairs of very large internal sacs, each 1–1½ times length of its segment. Male genitalia: Ninth segment with anterior margin slightly convex. Tenth tergite elongate, tip upturned in lateral aspect, tapering regularly to a narrow apex in dorsal aspect. Clasper with basal segment long, parallel-sided, barely attaining apex of tenth tergum; apical segment straight, tapering to a blunt point. Phallus long, slender, phallotheca straight, enlarged slightly apicad; apex with mesally sclerotized ventral and dorsal lips, with a large, ovoid lateral plate, displaced laterad as seen in dorsal aspect; internal sclerite long, slender, apical section curved ventrad and divided into right and left rami as seen in dorsal aspect.
