Hyleoglomeris lii sp. n.

Figs 9 D–F & 11.

Material examined: Holotype male ( IZAS), China, Guangxi Prov., Fuchuan County, Qishan Village, Cave Bai Fu Dong, 24.964284°N, 111.2752257°E, 27.01.12, leg. Li Youbang, Li Youting & Li Yousu (CHIgx12–LYB08). Paratypes. 1 male, 1 female ( MNHN CC 176), 1 female ( IZAS), 1 male, 1 female ( GNUG), same locality, together with holotype.

Name: Honours Li Youbang, the collector.

Diagnosis: Differs from all congeners in its residual coloration, as well as the bisunuate, subtrapeziform, central lobe of the telopod syncoxite, the absence of a distinct chitinized lobe from the telopod caudomedial femoral process, and 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 6.0 mm, width 2.0– 2.9 mm in both sexes. Holotype 2.9 mm wide. Coloration usually uniformly light grey-yellow (except for the usual flavous margins) ( Fig. 9 D–F), only a very faint pattern of 1+1 rounded darker, light grey-yellow, paramedian spots sometimes traceable on collum and several following tergites; front half of body coloured slightly more intensely. Head and collum the darkest, marbled light red-brown, collum with a light central spot.

Ocelli sometimes very light brownish, at least 6+1, translucid, barely visible. Antennomere 6 ca 2.0 times as long as high.

Second tergite with 5–7 transverse striae, two starting below, one level to, the remaining striae above schism, 4 or 5 striae (various, sometimes neither 1st nor last from below) crossing the dorsum; last crossing stria always a little deeper than others.

Male leg 17 ( Fig. 11 A) with a very low and irregularly shaped outer coxal lobe; telopodite 4-segmented, tarsus with a ventral spine in distal third.

Male leg 18 ( Fig. 11 B) with an arch-shaped syncoxital notch; telopodite 4-segmented.

Telopods ( Fig. 11 C, D) with a rather low, linguiform, apically evidently concave, sparsely setose, central syncoxital lobe flanked by two setose horns, each latter crowned by a minute lobule. Prefemur and, to a lesser extent, femur micropapillate laterally. Caudomedial femoral process prominent. Caudomedial process of tibia evident, membranous; tibial tubercle on caudal face distinct, papillate. Tarsus rather strongly sigmoid, narrowly rounded apically.

Remark: Because this species has retained some pigment in its tegument, it would seem to be hardly more than a troglophile.
