Remarks. McLachlan established the genus Anisocentropus based on 5 species, including the New Guinean Anisocentropus immunis . This species is known from only a single specimen, now with missing abdomen. The description of the species was brief: “Antennae with obscure greyish-brown annulations; head, thorax and legs pale ochreous; anterior wings densely clothed with short ochreous pubescence, costal margin darker; posterior wings hyaline,” and accompanied by only a simple habitus drawing. Ulmer identified Japanese (1907b) and Sri Lankan (1915) ochraceous coloured Anisocentropus specimens as Anisocentropus immunis based on McLachlan’s description of colour characters. However, as mentioned above, the Japanese species is Anisocentropus kawamurai (Iwata) and the Sri Lankan species is Anisocentropus ittikulama Schmid , as has been stated also by Flint (2000). Based mostly on the colour pattern presented in McLachlan’s original description, Neboiss (1986) identified specimens from New Guinea as Anisocentropus immunis McLachlan and drew the flagellomeres and the male genitalia in lateral view.
