Anilara angusta  Distinctive features

Red-brown to grey-brown, with a somewhat elongated pronotum contracted at its posterior just above its base and has its maximum width at about or just below the middle. On the ventral side between the metacoxae (intercoxal process) males have a shiny blackish boss without micro-puncturations. It is acutely angled at its anterior end, and terminates at its posterior end right up against the first visible posterior margin of the abdominal ventrites (on v3). Overall, this species is close to Anilara longicollis (q.v.) but differs in pronotum shape, boss and aedeagus.

Notes

This is one of four Anilara species that are commonly found on the dead or dying foliage of fallen eucalypt branches in the Adelaide area (see also A. obscura, A. longicollis and A. cf. anthaxoides).

Intriguingly, identified females of this species are not currently represented in SA collections. One explanation is that females may elude capture if their positioning behaviour or active time is very different to that of the males. Alternatively, females might be insufficiently distinct in their morphology from those of a co-occurring species such as A. obscura (or even A. longicollis) and so be misidentified.
