TMAG collections

Typical length (mm): 3.0
Flightedness: winged and assumed capable of flight

Morphology (characterised by L. Forster): — Antennae with large, compact, globular, three-segmented club — Elytra narrow and elongate with pale-orange spots — Fore-tibiae with even spines and a bifid tooth close to apex.

Assumed larval feeding: detritivore
Association with dead wood or old trees: at least facultatively saproxylic

Ecological attributes: — Affiliated with late-aged (ex-clearfelled) forest (Michaels, 1999) — 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: — Emergence trapping from log of Eucalyptus obliqua — Flight intercept trapping (trough below Malaise trap) — Hand collection (substrate not specified) — Malaise trapping — Pitfall trapping.
