Golovatch, Sergei I., Liu, Weixin & Geoffroy, Jean-Jacques, 2012, Review of the millipede genus Hyleoglomeris Verhoeff, 1910 in China, with descriptions of new species (Diplopoda, Glomerida, Glomeridae), Zootaxa 3358, pp. 1-27 : 22-24

Hyleoglomeris kunnan sp. n.

Fig. 17 .

Material examined: Holotype male ( IZAS), China, Guangxi Prov., Huanjiang County, core region of Mulun Karst, 650 m a.s.l., Cave Ganxiao Dong, 25.182633ºN, 108.031839ºE, 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 2nd 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 2nd 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 1st 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.
