Etymology.

The name for this species is derived from the Chinese Pinyin 'fēn chà’, which means ‘forked’, in reference to the fork-shaped anterior radical apophysis in male; term in apposition.

Diagnosis.

It differs from other congeners by the stem-cup-shaped dorsal tibial apophysis (Fig. 108B) and the ribbon-like embolus with a small outgrowth near tip in palp (Fig. 109B); female resembles Vittatus bian sp. n. in the closely positioned spermathecae (Figs 106C, 110C), but differs in the short and unmodified scapoid (Fig. 110A).
