Remarks.

This species externally resembles Tambocerus elongatus Shang and Zhang but can be separated from the latter by the male pygofer (Figs 10, 12) without process; the subgenital fig (Fig. 11) tapering from base to end; the aedeagal shaft (Figs 13-14) without depression at subapex in lateral view.

Etymology.

This species name is derived from the Latin word “dentatus”, referring to the dentate dorsal margin of the pygofer lobe.
