Hyleoglomeris tiani View in CoL sp. n.

Fig. 1 View FIGURE 1 .

Material examined: Holotype male ( IZAS), China, Hunan Prov., Linwu County, Huatang Town, Shimen Village, Cave Long Dong, 19.06.2009, leg. Tian Mingyi & Xue Zhihong (CHIhn09–LWX01). Paratype. 1 male ( SCAU), same locality, together with holotype.

Name: Honours Tian Mingyi, one of the collectors.

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, coupled with a rather short, subtrapeziform, faintly concave central lobe of the telopod syncoxite, a widely arch-shaped notch of male syncoxite 18, and a 3- segmented male telopodite 17. See also Key below.

Description: Length ca 6.0–7.0 mm, width 2.8 (paratype) or 3.0 mm (holotype). Coloration entirely pallid. Ocelli at least 5+1, translucid, mostly rather convex; Tömösváry’s organ transverse-oval, only slightly wider than long. Antennomere 6 ca 2.0 times as long as high.

Collum with two transverse striae. Second tergite with a narrow hyposchism not reaching behind the caudal tergal margin; 6 or 7 superficial transverse striae, 3 or 4 starting below schism, one level to, all others above schism while two (2nd and 3rd from below) crossing the dorsum. Male anal shield regularly rounded at caudal margin.

Leg 1 ( Fig. 1 View FIGURE 1 A) with a conspicuous, distomesal, finger-shaped, spinigerous, coxal process (k).

Leg 17 ( Fig. 1 View FIGURE 1 B) with a rather low and regularly rounded outer coxal lobe (cxl); telopodite 3-segmented, tarsus with two subapical spines.

Leg 18 ( Fig. 1 View FIGURE 1 C) with a broadly arch-shaped syncoxital notch (scxn); telopodite 4-segmented.

Telopods ( Fig. 1 View FIGURE 1 D, E) with a high, apically slightly concave, sparsely setose, central syncoxital lobe (scxl) flanked by two setose horns (scxh), each latter crowned with a minute, elongate lobule devoid of adjacent structures ( Fig. 1 View FIGURE 1 E). Prefemur and, to a lesser extent, femur micropapillate laterally. Prefemur with a well-developed frontomedial trichostele (= flagelliferous digit) (fpft). Femur with a smaller frontomedial trichostele (fft). Caudomedial femoral process (cfp) prominent, directed distomedially at ca 100º to femur, mostly strongly chitinized, apically with a small membranous sac (s). Caudomedial process of tibia (tip) evident, sac-shaped, membranous, with an evident, papillate tubercle at base. Tarsus subacuminate apically.

Remark: Since this species shows such troglomorphic traits as entirely unpigmented tegument and ocelli, it can well prove to be a troglobite.
