Material examined: Holotype male (IZAS), China, Guangxi Prov., Huanjiang County, core region of Mulun Karst, 650 m a.s.l., Cave Ganxiao Dong, 25.182633 ºN, 108.031839 ºE, 0 7.11. 2009, leg. Tian Mingyi et al. (CHIgx09–087). Paratypes. 1 female (SCAU), same locality, together with holotype.
Name. To emphasize the difficulties in reaching the type locality, “ kunnan ” in Chinese meaning “difficult”.
Diagnosis: Differs from congeners except H. mulunensis sp. n. by the 2 nd transverse stria on the collum being obliterated mid-dorsally, from H. mulunensis sp. n. by the absence of a setoid filament at the tip of the telopod syncoxital horns. See also Key below.
Description: All characters like in H. tiani sp. n., except as follows.
Length ca 7.5 (holotype) or 9.5 mm (paratype); width 4.0 (holotype) or 4.6 mm (paratype). Coloration uniformly yellow brown (paratype) to entirely pallid (holotype).
Ocelli at least 4 + 1, translucid, barely visible. Antennomere 6 ca 2.1 times as long as high.
Collum with two transverse striae, but 2 nd obliterated and interrupted mid-dorsally. Second tergite with 10 or 11 transverse striae, four starting below, one level to, the remaining striae above schism, four striae (neither 1 st nor last two ones from below) crossing the dorsum.
Male leg 17 (Fig. 17 A) with a high and regularly rounded outer coxal lobe; telopodite 4 -segmented, tarsus devoid of subapical spines.
Male leg 18 (Fig. 17 B) with a broadly arch-shaped syncoxital notch; telopodite 4 -segmented.
Telopods (Fig. 17 C–E) with a roundly subtrapeziform, sparsely setose, central syncoxital lobe flanked by two setose horns, each latter crowned by a minute lobule (Fig. 17 E). Both prefemur and, to a lesser extent, femur micropapillate laterally. Caudomedial femoral process prominent, subapically with a distinct lateral lobe on caudal face (Fig. 17 D). Caudomedial process of tibia rather evident, membranous; tibial tubercle on caudal face distinct, papillate. Tarsus rather strongly sigmoid, subacuminate apically.
Remark: Due to its troglomorphic traits, this species seems to be a troglobite.
