Key to the species of the genus Dolicholobosa (males)

1. Lateral lobes of tenth abdominal tergite spine-shaped with apices subacute; cerci with a carina on dorso-internal margin separately, inner margins near apical part slightly expanded and truncate; apices rounded; subapical part of genitalia dorsal surface with a depressed and long process which bent backwards and downwards, apical area slightly broadening with tip obtuse; ventral surface rectangular expanded laterally, of which apices truncate and with numerous sclerotized denticles ( Fig. 2 )............................................................................................ D. complanatis

- Lateral lobes of tenth abdominal tergite triangular with apices rounded; without other characteristics as above............ 2

2. Epiproct long, lateral edges of two-thirds base fused with tenth abdominal tergite; cerci slightly incurved, cylindrical at twothirds base, inner margins of third apical area concave, narrowing; apices subacute; the middle of genitalia dorsal surface with a tongue-shaped process, compressed, directed backwards, narrowing, apex rounded; lateral margins of ventral surface expanded, apical part faintly protruding backwards and bifurcated, pointing laterally, tapering, with apices rounded ( Fig. 1 )................................................................................... D. bisofurcula sp. nov.

- Epiproct short, indistinct; without other characteristics as listed above........................................... 3

3. Cerci cylindrical at two-thirds base, third apical area of inner margins slightly expanded inwards and compressed, slightly bent interio-dorsally; apices rounded; genitalia with a dorsal carinae which dorsal margin slightly convex at subapical part, apical area spine-shaped with apex acute, directed downwards; lateral margins of ventral surface sinuate, narrowing, apex subacute ( Wang, Li & Shi, 2019: Fig. 2 )..................................................................... D. acuta

- Cerci cylindrical, third apical area of dorsal surface slightly concave and faintly upcurved; apices rounded; genitalia with a dorsal carinae which dorsal margin slightly convex at the middle, apical area spine-shaped with apex subacute; lateral margin of ventral surface expanded, apical part feebly extended backwards forming depressed lateral lobes, slightly incurved, apices rounded, area between basal part of lateral lobes with a cluster of setae ( Fig. 3 )........................... D. rotundata
