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 : 11-12

Hyleoglomeris yinshi sp. n.

Fig. 8 .

Material examined: Holotype male ( MNHN CC 174), China, Guizhou Prov., Kaiyang County, Cave Xian Yan Dong, 19.02.2004, leg. S. Prevorčnik & B. Sket. Paratypes. 1 male, 1 female ( MNHN CC 174), 1 male, 1 female ( IZAS), 1 male ( ZMUM), same locality, together with holotype.

Name: To emphasize the animal coming from a cave, “ yinshi ” in Chinese meaning a “hermit”; a noun in apposition.

Diagnosis: Differs from congeners except H. eusulcata , H. mulunensis sp. n. and H. mashanorum sp. n. in the presence of only one complete transverse stria on the collum, from H. eusulcata by the absence of a transverse sulcus on the second tergite, from both H. mulunensis sp. n. and H. mashanorum sp. n. by the subquadrate central lobe of the telopod syncoxite and the shape of the notch in male syncoxite 18. See also Key below.

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

Length ca 5.0–6.0 mm (male) or 6.0–7.0 mm (female), width 2.2–2.9 mm (male) or 2.7–3.0 mm (female). Holotype 5.0 mm long, 2.3 mm wide. Coloration entirely pallid. Ocelli at least 4+1, translucid, barely visible. Antennomere 6 ca 2.0 times as long as high.

Collum with one transverse stria. Second tergite with 8–11 transverse striae, two starting below, 1 or 2 level to, the remaining striae above schism, 3–5 striae (various, but never 1st and/or last from below) crossing the dorsum.

Male leg 17 ( Fig. 8 A) with a high and highly irregularly shaped outer coxal lobe; telopodite 4-segmented, tarsus devoid of subapical spines.

Male leg 18 ( Fig. 8 B) with a broadly arch-shaped syncoxital notch; telopodite 4-segmented.

Telopods ( Fig. 8 C, D) with a high, linguiform, apically barely concave, sparsely setose, central syncoxital lobe flanked by two setose horns, each horn being crowned by a short minute lobule. Prefemur micropapillate laterally. Caudomedial femoral process prominent, subapically with a small lobe. Caudomedial process of tibia evident, membranous; tibial tubercle on caudal face distinct, papillate. Tarsus rather strongly sigmoid, narrowly rounded apically.

Remark: Due to its troglomorphic traits (unpigmented tegument and ocelli), this species seems to be a troglobite.
