Smicridea (Smicridea) conjuncta

This species appears to link S. (S.) brevuncata Flint to the two following new species, S. (S.) prorigera and S. (S.) ruginasa. It is like S. (S.) breviuncata in lacking the ventrolateral hook from the tenth tergite, but does have a slight development of the ventral margin in the area of the hook. It has a short, broad clasper similar to all these species with no other modifications. The tip of the phallus still clearly shows the same sclerites as do S. (S.) prorigera and S. (S.) ruginosa: the strong dorsolateral sclerites, the mesoventral area, dorsal lobe developed and lightly sclerotized, as well as internal sclerotization. In S. (S.) brevuncata only the dorsolateral sclerites are well developed; all other parts are membranous and unrecognisable.

ADULT.—Length of forewing, 6 mm. Color grayish-fuscous, front of head with paler hair, forewing grayish-fuscous, apical fringe with paler hair. Male abdomen with internal sacs, each slightly longer than its segment. Male genitalia: Ninth segment slightly sinuous, and a bit oblique anteriorly. Tenth tergite elongate, narrow in lateral aspect, with ventrolateral margin slightly produced; in dorsal aspect with lobes rounded, darkened mesally. Clasper short; basal segment broad, with scattered, long, large setae; apical segment curved mesad, tapering to a blunt point. Phallus tubular, apex inflated; with a pair of elongate dorsolateral sclerites; apicoventral surface enlarged and produced, with dorsal margin narrowly produced; internal sclerites complex.

MATERIAL.—Holotype, male: COLOMBIA. DPTO. ANTIOQUIA: Quebrada La Iguaná, 17 km NW Medellin [road to San Jerónimo], 14–15 Feb 1983, O.S. Flint, Jr. USNM Type.
