Geographical distribution. Known from low and middle elevation sites in Japan and Thailand.

Comments. The pair of developed internal glands in Hirotophora dividua are illustrated here for the first time (Fig. 12). They are connected to the flap-like spiracle openings. No such structure could be found in the other species of the genus and its function is uncertain. The phallus of this species differs from others by its epiphallus scales with several-pointed tips (Figs 38–39).
