Litoleptis

Key to the species of Litoleptis in Japan 1. First flagellomere sharpened to be like a needle at apex (Fig. 5 a). Female spermathecal duct accessory gland originates at base of spermatheca (Fig. 5 b). Male gonostylus with forcep-like extension hollowed dorsally and bifid unevenly at apex (Fig. 5 c). Aedeagus deeply notched at apex (Fig. 5 c). Lateral ejaculatory process absent (Fig. 5 c)..................................................................... L. japonica n. sp. - First flagellomere stylate, tapering toward apex. Female spermathecal duct accessory gland originates in middle of genital chamber and spermatheca. Male gonostylus with extension apically, of which tip not bifurcated. Aedeagus without notch at apex. Lateral ejaculatory process present........................................ 2 2. Lateral ejaculatory process round-shaped, without elongation (Fig. 9 b). Sperm sac widened and forked at anterior end (Fig. 9 b)................................................................... L. izuensis n. sp. - Lateral ejaculatory process elongated transversely (e.g. Fig. 5 b).

Ejaculatory apodeme more than one-fourth as long as length of gonocoxite (Fig. 8 b)...... L. himukaensis n. sp. - Ejaculatory apodeme more than one-fourth as long as length of gonocoxite.............................. 5 5. First flagellomere with distinctive depression at basal one-third to two-thirds of dorsal margin and enlarged at apex. Spermatheca conical-shaped in female (Fig. 6 b). Posteromedial margin in ventral surface of gonocoxite bear less than four bristles (Fig. 6 c).....................................................
