(= Cerophytidae part; Elateridae: Anischiinae).
Classification. Polyphaga: Elateriformia.
Distribution. Species of Anischia are known from the Neotropical region, New Guinea, New Caledonia and Australia.
Biogeographic regions: Neotropical, Oriental, Australian.
Biology. Nothing has been published on the biology of Anischia; however adults were collected in Panama from a fungus on the surface of a log, adults and an associated larva were found by sifting rotten wood and litter and associated with bracket fungi in New Caledonia, and Australian adults were taken by pyrethrin fogging logs.
Notes. The genus Anischia Fleutiaux (1896) was described as a eucnemid, but has usually been placed in Cerophytidae based mainly on the absence of metacoxal plates. Lawrence and Newton (1995) tentatively placed the genus in Elateridae, but it has become evident that although the taxon belongs within the Elateroidea, it cannot be accommodated in any of the presently recognized families (Muona 1995). The larva, which resembles those of some of the more basal Eucnemidae, is currently being described as part of an analysis of the elateroid complex (Muona and Lawrence, in preparation). Data at least partly checked by J. Muona.
