Taibainus gen. n.

Type species. Taibainus shanensis sp. n.

Etymology. The generic name is derived from the name of the area where the new species was found. Gender masculine.

Diagnosis. Small­sized, dark­coloured Erigoninae . Total length ca 1.46. Chaetotaxy unclear (spines lost or reduced). Metatarsus IV without trichobothrium. TmI ca 0.60. The genus is characterised by a combination of the following characters: male carapace unmodified, cephalic pits present. Palpal structure very simple. Palpal tibia unmodified. Paracymbium moderately small, simple in shape. Suprategular apophysis short but wide, median membrane well­developed. Embolic division Z­shaped. Embolus relatively short, straight.

Taxonomic remarks. The taxonomic position of this new genus is unclear, especially as the female is unknown. The embolic division of Taibainus shanensis sp. n. is similar to that of Erigonoplus Simon 1884 , in particular E. globipes (L. Koch 1872) , but I am not inclined to combine these genera, because Erigonoplus shows certain important differences, e.g. modified male carapace and palpal tibia, armed femora I, etc.
