Hyleoglomeris gudu sp. n.

Fig. 7 .

Material examined: Holotype male ( MNHN CC 173), China, Guizhou Prov., Anlong County, Cave Hei Dong, 17.02.2004, leg. S. Prevorčnik & B. Sket.

Name: To emphasize the animal coming from a barely populated area and having been captured alone, “ gudu ” in Chinese meaning “lonely”; a noun in apposition.

Diagnosis: Differs in the presence of a lobe on the caudomedial process of the telopod femur, of a particularly high, linguiform, central lobe of the telopod syncoxite, coupled with 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 6.5 mm, width 4.0 mm. Coloration entirely pallid. Ocelli at least 3+1, translucid, barely visible. Antennomere 6 ca 2.2 times as long as high.

Second tergite with six transverse striae, two starting below, one level to, the remaining striae above schism, three striae (2nd, 3rd and 4th from below) crossing the dorsum.

Leg 17 ( Fig. 7 A) with a low and irregularly shaped outer coxal lobe; telopodite 4-segmented, tarsus with one subapical spine.

Leg 18 ( Fig. 7 B) with an arch-shaped syncoxital notch; telopodite 4-segmented.

Telopods ( Fig. 7 C) with a high, linguiform, 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, subapically with an evident lobe. Caudomedial process of tibia prominent, membranous; tibial tubercle on caudal face evident, papillate. Tarsus rather strongly sigmoid, narrowly rounded apically.

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