Diagnosis. Males of Habrocestum imilchang are most similar to the males of H. albopunctatum Wesolowska & van Harten 2002 , as both share a thin, long and slightly bent embolus, but can be distinguished from the latter species by the smooth and rounded anterior lobe of the tegulum (vs. cone shaped in H. albopuctatum ), and a cheliceral retromargin with a serrated tooth (vs. bifurcated tooth in H. albopunctatum ) (compare Figure 2E–F View Figure 2 with Wesołowska & van Harten 2002, figs. 5–10).
Description. Male (holotype, Figure 2A–C, G View Figure 2 , colouration in alcohol): carapace, clypeus and chelicerae brown; labium, endites, sternum, legs dark brown; eye field black; opisthosoma pale, with numerous brown transverse stripes. Carapace with scattered fine black hairs. Fovea narrow, longitudinal, straight, black. Cheliceral promargin with two tiny teeth, a bit spaced; retromargin with a serrated tooth ( Figure 2G View Figure 2 ). Opisthosoma oval, hirsute. Body length. 4.13. Carapace 2.28 long, 1.75 wide. Abdomen 1.86 long, 1.27 wide. Ocular area 1.01 long, 1.58 wide.

Length of chelicerae 0.71. Clypeus height at AMEs 0.06. Sternum 0.80 long, 0.55 wide. Length of pedipalp and legs: pedipalp 1.87 [0.86, 0.15, 0.22, 0.64], I 4.05 [1.29, 0.62, 0.98, 0.73, 0.43], II 3.27 [1.12, 0.45, 0.73, 0.59, 0.38], III 3.65 [1.16, 0.55, 0.78, 0.76, 0.40], IV 3.93 [1.26, 0.44, 0.80, 0.96, 0.47]. Leg formula: 1432. Spination of pedipalp: femur pld 2 do 2, patella pl 2 do 1, tibia pld 1 do 2 rl 1, tarsus/cymbium pl 2 do 2 rl 1 rld 1; legs: femur I pld 1 do 3, II–IV pld 1 do 3 rld 1; patellae I–II 0, III–IV pld 1 rld 1; tibia I plv 3 rlv 3, II plv 2 rlv 2, III pl 2 pld 1 plv 2 rl 1 rld 1 rlv 1, IV pl 2 pld 1 plv 2 rld 1 rlv 1; metatarsus I–II plv 2 rlv 2, II pl 1 plv 2 rlv 2, III pl 2 pld 2 plv 2 rl 2 rld 2 rlv 2, IV pl 2 pld 1 plv 1 rl 2 rld 1 rlv 2; tarsi I–IV 0. Pedipalp ( Figure 2D–F View Figure 2 ): Palpal femur proximally with a small femoral apophysis ( Figure 2D View Figure 2 ). RTA short, narrow, tube-like, slightly bent at middle, tip directed toward a 10 o’clock position retrolateral view ( Figure 2F View Figure 2 ). Tegulum with a slightly long proximal lobe, protruding posterolaterally ( Figure 2E View Figure 2 ). Embolus broad at base, long, with narrow apex, arising from under tegular ledge, directed at 12-o’ clock ventrally ( Figure 2E View Figure 2 ).
