Distribution. Ehime Prefecture, Japan. In the Shikoku district, this species shows a nearly parapatric distribution ( Fig. 5 ) with two closely related species (see Fig. 3 ) C. unicatus (Yaginuma, 1977) and C. sanoi ( Nishikawa, 2009) .

Diagnosis. The shape of the male palp of Coelotes mohrii is unique: the embolus extends in a counterclockwise direction (left palp) from the anterior end of the genital bulb, and the conductor and median apophysis are both located on the retrolateral side of tegulum ( Fig. 4a, b ).
