Type species: Leptochirus (Tropiochirus) proteus Fauvel, 1864: 16 , fixed by subsequent designation by Lucas, 1920: 659.

Diagnosis

The subgenus Tropiochirus can be distinguished from all other subgenera of Leptochirus by the median sulcus on the frons ( Figures 1A , 2A–I ), the apex of prosternal process dilated as a circular plate behind the procoxa ( Figure 1B ) and the outer and inner lateral teeth of head fused resembling a transverse septum ( Figures 1A , 2A–I ).
