Genus Flexicrurum Tong & Li, 2007

Type species.

Flexicrurum flexicrurum Tong & Li, 2007 from China, Hainan Island, Wuzhishan, Wuzhishan City, 16.IV.2005 (IZCAS).

Emended diagnosis.

Flexicrurum Tong & Li, 2007, resembles Althepus Thorell, 1898, and Leclercera Deeleman-Reinhold, 1995. However, Flexicrurum can be differentiated by the combination of the following characteristics: 1) the tibia of the male palp is strongly rotated inward (vs absence of rotated male palpal tibia in Althepus and Leclercera ); 2) presence of a slender bulbal apophysis (vs absence of slender bulbal apophysis in Althepus and Leclercera ); 3) cymbium with a strong lateral protrusion (vs cymbium with slightly tilted protrusion in Althepus and Leclercera ); 4) cymbium bearing a one- or two-bulge posterolateral cymbial apophysis (vs cymbium with lateral lanceolate or hook-shaped, spine like apophysis in Althepus ; cymbium with retrolateral apophysis in Leclercera ); 5) absence of promarginal cheliceral teeth (vs 1-2 promarginal cheliceral teeth in Althepus and Leclercera ); 6) embolus distinctly short (vs embolus long and slender in Althepus and Leclercera ); 7) internal endogyne with the presence of a distinct vertical duct medially bearing different structures of spermathecae (vs absence of the vertical duct in Althepus and Leclercera ).
