Remarks. This new species is similar to Alishania formosana (Matsumura, 1914) in external appearance, but can be distinguished from the latter by the absencee of appendages on the aedeagal shafts (Figs.12, 13,14), the style with both medial and lateral processes forked (Figs.15, 16), and the posterior margin of the valve roundly produced(Fig.10).

Etymology. This new species is named after its type locality “Foding”.
