Coccopsilis pectinata sp. nov.

Diagnosis. This new species shows all the characters we regard as typical of Coccopsilis . A structure specific to C. pectinata is the gonostylus, which in its ventral aspect is more than twice as long as wide, nearly parallel-sided, and equipped with a long, comb-shaped claw that occupies about two thirds of the gonostylar length. Since all the spines forming the comb are equally long, its edge is straight rather than rounded ( Fig. 4 , ↓ 3). Females and preimaginal stages of this species are unknown.

Other male characters. Body size 1.3 mm. Head. Eye bridge 1 ommatidium long at vertex. Antenna longer than body, as long as wing. 12 flagellomeres; apical flagellomere long, composed of two bodies; circumfila on flagellomeres 1–11. Neck of fourth flagellomere 1.7 times as long as node ( Fig. 5 ). Palpus slightly shorter than head height, 4 setose, subcylindrical segments, apical segment longest of all. Thorax. Pronotum with 0–1 seta; anepisternum with 1 seta; anepimeron with 0–2 setae. Wing. Length / width ratio 3.3. Legs. Foreleg: femur slightly longer than tibia, tibia 0.8 times as long as T 2. Genitalia ( Fig. 4 ). Gonocoxal synsclerite: processes slightly bent, apices curved ventrally; dorsoposterior portions broad, somewhat angular, only slightly prolonged posteriorly. Aedeagal apodeme about as long as parameres, slender, moderately sclerotized with membranous apex. Parameres of speciesspecific outline as illustrated, including a slightly notched apex (↓ 4).

Etymology. The Latin adjective pectinata means pectinate or ̒with a comb’, with reference to the gonostylar claw whose size and shape are characteristic of this species.
