Diagnosis. This species is very similar to C. fortunatus but differs in having a narrower arista-like stylus ( Fig. 81 View FIGURES 77–91 ) and narrower fore tibia ( Fig. 84 View FIGURES 77–91 ).
Description. Male. Wing length 2.9–3.3 mm. Similar to C. fortunatus except as noted: Head: Arista-like stylus ( Fig. 81 View FIGURES 77–91 ) with smaller narrower apical lamella, with only about apical half of article 2 thickened. Legs: Foreleg ( Fig. 84 View FIGURES 77–91 ): Tibia not as strongly swollen, subequal to or slightly less than width of fore femur. Tarsomere 3 with apex slightly less broadened, with shorter dorsal microsetulae.
Female. Wing length 3.1–3.3 mm.
Distribution and seasonal occurrence. This species appears restricted to the Appalachian Mountains from Nova Scotia south to North Carolina ( Fig. 94 View FIGURE 94 ), occurring at higher elevations in the southern Appalachians. Adults have been collected in July and August.
Etymology. The specific epithet is from the Greek leptos (thin, slender) + fortunatus , in reference to this species being similar to C. fortunatus but having a thinner arista-like stylus and fore tibia.
