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

Ecology

Assumed larval feeding: fungus-feeder
Association with dead wood or old trees: at least facultatively 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 log of Eucalyptus obliqua — Flight intercept trapping (trough below Malaise trap) — Knockdown fogging of canopy of Nothofagus cunninghamii — Knockdown spraying of bark of Eucalyptus obliqua — Knockdown spraying of bark of Eucalyptus sp. — Malaise trapping — Pitfall trapping — Sticky trapping on Eucalyptus obliqua — Vane trapping.
