Comprehensive Description

Smicridea (Smicridea) anaticula

This is a very distinctive new species probably most closely related to the new species S.amplispina. Both species agree in having a modified spine(s) at the inner apex of the basal clasper segment and having the apical clasper segment rather strongly modified. However the nature of the modification of the apical segment is very different in the two species. The very short, angled, and pointed apical segment in S. anaticula is unique within the genus.

ADULT.—Length of forewing, 5 mm. Color fuscous, some specimens with white hair anteromesally on head and on outer face of basal tarsal segments of midleg; forewing uniformly fuscous. Abdomen with two pairs of reticulate internal sacs. Male genitalia: Ninth segment with anterior margin truncate. Tenth tergite in lateral aspect with tip erect; in dorsal aspect tapering to a slightly produced apicomesal lobe. Clasper long, basal segment parallel-sided, apex on inner face bearing a spinelike seta; apical segment very short, sharply angled mesad tapering to a point. Aedeagus tubular, curving directly from base; apex membranous, dorsal surface slightly thickened; inner sclerite threadlike, slightly sclerotized, apex recurved ventrally.
