Distribution: Japan, Russia (Amurland).

Remarks: Anisocentropus immunis McLachlan, 1863 was described from New Guinea (sex not stated, very briefly described and only habitus figure presented). Type depository: NHML; Abdomen lost ( McLachlan 1863). Ulmer (1907b) identified, illustrated and re-described a species from Japan as Anisocentropus immunis based on McLachlan’s brief description of body and wing colour. Later, Ulmer (1951) synonymised the genera Kizakia and Anisocentropus , and Kizakia kawamurai Iwata with his (1907b) concept of Japanese Anisocentropus immunis McLachlan. Neboiss (1986: 229) , however, illustrated a male of A. immunis from New Guinea and concluded that the figures by Ulmer (1907b) as A. immunis McLachlan from Japan represent another species. Anisocentropus immunis McLachlan from New Guinea has short gonocoxites and a well-developed lateral flank on each posterolateral margin of segment IX, and is a true member of the Anisocentropus latifascia diagnostic species-group. The species drawn by Ulmer from Japan has very long and slender gonocoxites and no lateral flanks. Anisocentropus kawamurai is very close to A. minutus Martynov from China (Hainan) and is identical to Ganonema pallidum Martynov, 1935 , from Amurland.

Based on larval material of this species from Japan (Honshu, Nagano Prefecture, Lake Kizaki), Iwata (1927) established a new genus, Kizakia within the Molannidae . According to the male genitalia, it belongs to the genus Anisocentropus and resembles Anisocentropus minutus Martynov. However , it is distinct from A. minutus in having more slender median processes on segment IX, a differently shaped, ventrad-curving apex of segment X, and larger body size. Its body and wing colour may change from darker greyish brown to ochraceous in different habitats or during preservation. For example, a pinned specimen collected on Honshu Island near Tokyo in 1952 (W. Nakahara) is light ochraceous and freshly collected specimens in 2007 from Hokkaido are dark greyish brown.
