Leucotrichia Mosely (See also p. 120) KEY TO MALES OF NEARCTIC SPECIES 1. Ninth segment with a pair of long, sclerotized spurs and long styles, fig. 915 notosa n. sp. Ninth segment without long, project- ing spurs and styles, fig. 916 2 2. Eighth sternite with lateral margin forming long, triangular lobes, fig. 917 sarita n. sp. Eighth sternite without lateral lobes but with a pair of pointed lobes situated ventrad, figs. 916, 918. ... 3 3. Seventh sternite with an apico-mesal, short process; aedeagus with a long, dorsal loop extending over its base, fig. 918 limpia n. sp. Seventh sternite with no short process but instead with an apico-mesal brush of dark setae; aedeagus with a pair of short, dorsal processes not produced into a loop, fig. 916 pictipes (Banks) Leucotrichia notosa new species The long, lateral styles of the ninth seg- ment distinguish this species from all others in the genus, as pointed out in the preceding key. Male.—Length 4 mm. Color mottled light and dark shades of gray, the legs con- spicuously banded, essentially similar in this characteristic to pictipes. General structure typical for the genus. Seventh segment with- out a mesal projection. Eighth segment with the tergite reduced to a narrow triangular. Please note that these images
