Australian Pentaneurini genus E
This taxon, and others named in the same manner, derive from Australian larvae, some of which are reared, that do not correspond with northern hemisphere defined taxa. No formal diagnosis is provided here – eventually, and with rearings and especially some insights from molecular data, formal taxonomic treatment may be provided.
Pentaneurini genus E was segregated originally as a larva with a narrow, elongate four-toothed ligula. The distinctive ventral setal arrangement with S10, the pit and SSm transversely aligned, confirmed that this was not a previously known animal with an aberrant four-toothed ligula. All larvae from several localities in south-western Western Australia possessed this characteristic ligula. However, some recent material from NSW, otherwise identical in every detail, have the ligula mostly four but sometimes five-toothed. The pupa is of the Paramerina type.
In Western Australian evidence is for acidophily.
