Smicridea (Smicridea) microsaccata Flint 1991

Smicridea (Smicridea) microsaccata

This species is perhaps most closely related to S. (S.) curvipenis, new species, on the basis of reduction in size of the abdominal pheromone sacs. The terminal pair are half the size of those of S. (S.) curvipenis, but the anterior pair are wholly lost. In addition the tenth tergum is upturned apically, more like that of S. (S.) grandisaccata, new species, but the broad tip of the apical clasper segment is unique to S. (S.) microsaccata.

ADULT.—Length of forewing, 9 mm. Color in alcohol, uniformly dark brown. Male abdomen with a pair of minute and easily overlooked pheromone sacs between segments 7 and 8; lacking anteromost pair of sacs. Male genitalia: Ninth segment with anterior margin slightly and broadly produced centrally. Tenth tergum produced dorsad basally; tergite elongate, tip slightly upturned in lateral aspect; apex produced in dorsal aspect. Clasper long, parallel-sided, basal segment surpassing tip of tenth tergite; apical segment short, tip truncate in posteroventral aspect Phallus tubular, long, phallotheca slightly curved; apex with lightly sclerotized, mesal surfaces dorsally and ventrally, with a large, ovoid, lateral plate which is displaced laterad as seen in dorsal aspect

MATERIAL.—Holotype, male: COLOMBIA. DPTO. ANTIOQUIA: Urrao, 2000–2500 m, 18 Mar 1984, U. Matthias. USNM Type.
