Source literature on morphology and taxonomy (*primary taxonomic source, where identified):

Ecology

Assumed larval feeding: detritivore
Association with dead wood or old trees: obligately saproxylic

Ecological attributes: — May occupy logs or trunks of Eucalyptus obliqua, at least temporarily, since found having emerged within a year of felling (Grove & Bashford, 2003) — May occupy logs or trunks of Eucalyptus obliqua, at least temporarily, since found having emerged within six years of felling (Grove et al., 2009).

Collection method(s) for TMAG material: — Baited trapping (funnel trap) — Emergence trapping from cut billets of Eucalyptus obliqua (Harrison, 2007) — Emergence trapping from log of Eucalyptus obliqua — Malaise trapping — Pipe trapping — Vane trapping.
