Remarks. This new species is similar to Shibinga nigra Song, Yuan & Jiang , but has the pygofer lobe with posterior margin rounded, and the aedeagal shaft of uniform width and bent dorsad from the middle in lateral view. Shibinga nigra Song, Yuan & Jiang has the pygofer lobe with the posterior margin indented, and the aedeagal shaft triangular and slightly curved dorsad in lateral view.
