Hyleoglomeris heshang sp. n.

Fig. 12 .

Material examined: Holotype male ( IZAS), China, Guangxi Prov., Xilin County, Zhou Bang Village, Cave Zhou Bang, Cave 2, ca 890 m a.s.l., 24.55353°N, 105.11073°E, 18.04.2010, leg. L. Deharveng et al. (CHIgx10–29). Paratypes. 1 female ( IZAS), 1 male, 1 female ( MNHN CC 177), 1 male, 1 female ( SCAU), 1 male ( ZMUM), same locality, together with holotype.

Name: To emphasize the animal coming on a lonely cave, “ heshang ” in Chinese meaning a “monk”; a noun in apposition.

Diagnosis: Differs in its residual coloration of a few ocelli, as well as by the roundly subtriangular central lobe of the telopod syncoxite, the presence of a distinct chitinized lobe from the telopod caudomedial femoral process, and the absence 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 5.5–6.0 mm, width 2.5–3.0 mm in both sexes. Holotype 6.0 mm long, 3.0 mm wide. Coloration entirely pallid to sometimes very faintly yellowish, 2 or 3 uppermost ocelli sometimes faintly brownish.

Ocelli 5+1 or 6+1, translucid, often barely visible. Antennomere 6 ca 1.7–1.8 times as long as high.

Second tergite with 8 or 9 transverse striae, three starting below, 1 or 2 level to, the remaining striae above schism, 5 or 6 striae (neither 1st nor last from below) crossing the dorsum.

Male leg 17 ( Fig. 12 A) with a high and rather regularly rounded outer coxal lobe; telopodite 4-segmented, tarsus with two subapical spines.

Male leg 18 ( Fig. 12 B) with a narrowly arch-shaped syncoxital notch; telopodite 4-segmented.

Telopods ( Fig. 12 C–E) with a rather low, roundly subtriangular, sparsely setose, central syncoxital lobe flanked by two setose horns, each latter crowned by a minute lobule ( Fig. 12 E). Caudomedial femoral process prominent, subapically with a distinct lateral lobe on caudal face. A caudomedial process of tibia absent; tibial tubercle on caudal face evident, papillate. Tarsus rather strongly sigmoid, subacuminate apically.

Remark: Due to its troglomorphic traits, this species might well prove to be a troglobite.
