Hyleoglomeris nigu, Golovatch, Sergei I., Liu, Weixin & Geoffroy, Jean-Jacques, 2012

Hyleoglomeris nigu View in CoL sp. n.

Fig. 6 View FIGURE 6 .

Material examined: Holotype male ( MNHN CC 172), China, Guizhou Prov., Qianxi County, Honglin Town, Cave Luo Sai Dong, 22.11.2003, leg. L. Latella & D. Avesani. Paratypes. 1 female ( MNHN CC 172), 1 female ( IZAS), same locality, together with holotype.

Name: To emphasize the animal being isolated in its cave, “ nigu ” in Chinese meaning a “nun”; 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, of a telopod tibial process, coupled with a low, roundly subtriangular, central lobe of the telopod syncoxite. See also Key below.

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

Length ca 5.5 mm ( holotype) or 7.0–8.0 mm ( paratypes), width 2.8 mm ( holotype) or 3.0 mm ( paratypes). Coloration entirely pallid. Ocelli at least 5+1, translucid, mostly barely visible. Antennomere 6 ca 1.8 times as long as high.

Second tergite with seven transverse striae, three starting below, one level to, the remaining striae above schism, 4 ( holotype) or 3 ( paratypes) striae (various, but not uppermost one) from below crossing the dorsum.

Male leg 17 ( Fig. 6 View FIGURE 6 A) with a high and regularly rounded outer coxal lobe; telopodite 4-segmented, tarsus devoid of subapical spines.

Male leg 18 ( Fig. 6 View FIGURE 6 B) with a V-shaped syncoxital notch; telopodite 4-segmented.

Telopods ( Fig. 6 View FIGURE 6 C, D) with a rather low, roundly subtriangular, central syncoxital lobe flanked by two setose horns, each latter crowned by a minute lobule. Neither prefemur nor femur micropapillate laterally. Caudomedial femoral process prominent. Caudomedial process of tibia absent; tibial tubercle on caudal face evident, papillate and pilose. Tarsus evidently sigmoid, subacuminate apically.

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