Smicridea (Smicridea) calopa Flint 1974

Smicridea (S.) calopa

This species is probably most closely related to the preceding species, S. turrialbana, new species. It is easily recognized by the rather simple ventrolateral processes of the aedeagus which bear a number of small teeth.

The female vagina presents certain diagnostic characters, most noticeably the rather complex hooklike folds capping the apex and the anteromesal excision of the lateral supports.

ADULT.—Length of forewing 4.5 mm. Color in alcohol brown; mostly denuded but indications are compatible with typical pattern (cf. Figure 20). Male genitalia: Ninth segment with anterior margin produced into a broad shallow lobe. Tenth tergite in lateral aspect narrow, elongate, tip produced into a dorsal point; in dorsal aspect with lateral margin slightly produced basad, apex pointed. Clasper with basal segment long, slightly inflated subapically; apical segment with tip produced into a point. Aedeagus enlarged basally, open apically; apicoventrally produced into a pair of elongate, rather irregular processes bearing a number of lateral points; with a pair of internal spines; middorsally with a membranous appendage. Female genitalia: Ninth segment produced anterolaterally. Vagina with central sclerite shield-shaped with a heart-shaped opening; lateral supports V-shaped, inner margin with a deep excision anteromesally, margins smooth, apex of each arm produced into a hooked lobe and a complex of sclerotized folds.

IMMATURE STAGES.—Unknown.

MATERIAL.—Holotype, male: MEXICO, VERACRUZ, Rió Tacolopan, route 180, km 551, 25–26 July 1966, Flint and Ortiz. USNM Type 72698. Paratypes: Same data, 2 1 .

BIOLOGY.—The adults were attracted to an ultraviolet light placed beside a clear, gravel-bottomed, spring-fed stream, 1–2 meters wide.
