Fig. 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. FIGURE 6. Hyleoglomeris nigu sp. n. , holotype. A: leg 17, front view. B: leg 18, front view. C & D: left half of telopods, front and caudal views, respectively. Scale bar: 0.2 mm. 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. FIGURE 7. Hyleoglomeris gudu sp. n. , holotype. A: leg 17, front view. B: leg 18, front view. C: right half of telopods, front view. Scale bar: 0.2 mm. 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 A) with a high and regularly rounded outer coxal lobe; telopodite 4-segmented, tarsus devoid of subapical spines. Male leg 18 ( Fig. 6 B) with a V-shaped syncoxital notch; telopodite 4-segmented. Telopods ( Fig. 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.
