Smicridea (Smicridea) prorigera

This and S. (S.) ruginasa, new species, are very closely related. The lack of the digitiform process on basal clasper segment, the narrowly pointed ventral process of the tenth tergum, and pointed apical clasper segment of S. (S.) prorigera are distinctive.

ADULT.—Length of forewing 5.5–6 mm. Color fuscous; forewing fuscous with 2 pairs of white spots (the remnants of the typical two cross-bands). Male abdomen with 2 pairs of large internal sacs, each 1½ limes as long as its segment. Male genitalia: Ninth segment nearly vertical anteriorly. Tenth tergite short, upturned, rounded dorsally, with a ventrolateral projection, pointed in lateral aspect; apex drawn out into a mesally directed hook in dorsal aspect. Clasper short; basal segment broad, with scattered, long, large setae; apical segment pointed and curved mesoventrad in both lateral and dorsal aspects. Phallus tubular, apex inflated; with a pair of elongate dorsolateral sclerites, mesoventrally produced into a narrow process beneath tip, with complex internal sclerites.
