Etymology.

This name is derived from the Chinese Pinyin ‘pán’ meaning ‘fig’, for the broad, fig-like terminal apophysis in this species; noun in apposition.

Diagnosis.

It differs from the congener Vittatus bian sp. n. by light coloration, much shorter dorsal tibial apophysis (Fig. 117A), prominent and broad branch of radical apophysis (Fig. 117B) and short scape (as long as wide).
