Material.
Holotype: male, cave Shenxian Dong, Qiaoshan, Xinming, Huangshan, Anhui, 30°23'9.55"N, 118°14'7.66"E, 366 m in altitude, 2016-IV-22, leg. Wenbo Li, in SCAU; Paratypes: 3 males and 2 females, idem; 12 males and 15 females, same cave, 2018-XII-24, leg. Weibo Li, Mengzhen Chen, Zhuanghui Qin, Jingli Cheng & Mingyi Tian, in SCAU and in the animal collections of Anhui University, Hefei, China (AHU) respectively.
Diagnosis.
A rather small eyeless trechine beetle, yellowish brown, body thin and elongate, sparsely pubescent.
Description.
Length: 3.2-3.5 mm (including mandibles); width: 0.9-1.0 mm. Habitus as in Fig. 6 View Figure 6 .
Head longer than wide, HLm/HW = 1.38-1.42, HLl/HW = 1.08-1.2; right mandible bidentate (but tricuspid in three individuals); antennae extending beyond basal 2/5 of elytra.
Pronotum slightly wider than longer, PnL/PnW = 0.90-0.93, shorter than head, PnL/HLm = 0.72-0.75, wider than head, PnW/HW = 1.20-1.24, base narrower than front, PbW/PfW = 0.83-0.87, lateral margins more contracted behind the widest portion than in Wanoblemus wui Tian & Fang, 2016.
Elytra slightly thinner than those in W. wui , longer than fore body, EL/(HLm+PnL) = 1.28-1.31, EL/(HLl+PnL) = 1.50-1.62, much longer than wide, EL/EW = 1.77-1.81; much wider than pronotum, EW/PnW = 1.51-1.53; chaetotaxy similar in W. wui (Fig. 3B View Figure 3 ).
VII ventrite bisetose in male, while quadrisetose in female.
Male genitalia (Fig. 4C, D View Figure 4 ): The median lobe of aedeagus well-sclerotized, small but more elongate than the one of W. wui , and less curved ventrally in middle part; membranous opening large, rather sharp at apex, base larger, with a small sagittal aileron; in dorsal view, apical lobe much longer than wide, gently contracted towards apex which is broad; parameres shorter than median lobe, both widened at apices, each armed with four long apical setae.
Remarks.
This new species is very similar to the type species W. wui which occurs in the cave Baiyun Dong, Xuancheng Shi, approximately 46 km in a straight-line distance from the cave Shenxian Dong. However, the new species is smaller and slenderer than the type species, and with a longer and more elongated aedeagus.
Etymology.
To refer to the type locality.
Distribution.
China (Anhui). Known only from the cave Shenxian Dong in Huangshan Shi.
The specimens collected in 2016 were found in a small wet area about 300 m from the cave entrance. The specimens collected in 2018 were found in dark areas 200-300 m from the entrance.
