Diagnosis (after Tanabe 1994)

The species differs from all congeners mainly by the shorter gonopod telopodite carrying a longitudinal blade and by a trifurcate apex of telopodite.

Distribution

Japan: western part of Hokkaido.

Remarks

This species was originally described from Hokkaido Island as Profontaria takakuwai (see Verhoeff 1941). The genus Profontaria was later shown to be a senior synonym of originally a Hokkaido genus Ezodesmus ( Hoffman 1956) . Miyosi (1959) synonymized the type species Ezodesmus lunatus with Profontaria takakuwai . Finally Tanabe (1994) proposed Profontaria to be a junior synonym of Levizonus , with the new combination Levizonus takakuwai . This species appears to be distributed in the western part of Hokkaido (see Tanabe 1994).
