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 : 8-9

Hyleoglomeris wuse sp. n.

Fig. 5 .

Material examined: Holotype male ( IZAS), China, Guizhou Prov., Libo County, Maolan Town, Cave Dong Ge Dong, 26.07.2009, leg. Tian Mingyi & Xue Zhihong (CHIgz09–LWX13). Paratypes. 1 female ( IZAS), 1 male, 1 female ( SCAU), 1 male, 2 females ( MNHN CC 171), 1 male ( ZMUM), 1 female ( GNUG), same locality, together with holotype.

Name: To emphasize the animal being completely unpigmented, “ wuse ” in Chinese meaning “uncoloured”; a noun in apposition.

Diagnosis: Differs from all congeners in the absence of a lobe on the caudomedial process of the telopod femur, of a setoid filament at the tip of the telopod syncoxital horns, coupled with a narrow, rather high, linguiform, central lobe of the telopod syncoxite, as well as a 3-segmented male telopodite 17. See also Key below.

Description: All characters like in H. tiani sp. n., except as follows.

Length ca 6.0– 7.5 mm (male) or 6.5–8.0 mm (female), width 3.2–4.0 mm in both sexes. Holotype 6.0 mm long and 3.6 mm wide. Coloration entirely pallid. Ocelli at least 4+1, translucid, mostly barely visible. Antennomere 6 ca 2.2 times as long as high.

Second tergite with 9 or 10 (usually 10) transverse striae, four starting below, one level to, the remaining striae above schism, normally seven striae (usually 1st to 3rd and 5th to 8th) from below crossing the dorsum.

Male leg 17 ( Fig. 5 A) with a rather high and regularly rounded outer coxal lobe; telopodite 3-segmented, tarsus devoid of subapical spines.

Male leg 18 ( Fig. 5 B) with a rather narrowly arch-shaped syncoxital notch; telopodite 4-segmented.

Telopods ( Fig. 5 C, D) with a high, linguiform, rather narrow, sparsely setose, central syncoxital lobe flanked by two setose horns, each latter crowned by a minute lobule ( Fig. 5 D). Prefemur and femur sparsely micropapillate laterally. Caudomedial femoral process prominent. Caudomedial process of tibia evident, membranous; tibial tubercle on caudal face distinct, papillate. Tarsus rather moderately sigmoid, rounded apically.

Remark: Only one species of Hyleoglomeris , H. eusulcata , has hitherto been known from Guizhou Province, also a presumed troglobite from Libo County ( Golovatch et al. 2006).
