Key to the species of Litoleptis View in CoL in Japan

1. First flagellomere sharpened to be like a needle at apex ( Fig. 5 View FIGURE 5 a). Female spermathecal duct accessory gland originates at base of spermatheca ( Fig. 5 View FIGURE 5 b). Male gonostylus with forcep-like extension hollowed dorsally and bifid unevenly at apex ( Fig. 5 View FIGURE 5 c). Aedeagus deeply notched at apex ( Fig. 5 View FIGURE 5 c). Lateral ejaculatory process absent ( Fig. 5 View FIGURE 5 c)..................................................................... L. japonica View in CoL 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 View FIGURE 9 b). Sperm sac widened and forked at anterior end ( Fig. 9 View FIGURE 9 b)................................................................... L. izuensis View in CoL n. sp.

4. Ejaculatory apodeme more than one-fourth as long as length of gonocoxite ( Fig. 8 View FIGURE 8 b)...... L. himukaensis View in CoL 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 View FIGURE 6 b). Posteromedial margin in ventral surface of gonocoxite bear less than four bristles ( Fig. 6 View FIGURE 6 c)..................................................... L. kiiensis View in CoL n. sp.
