    Yep Reiner...Notonomus. Very difficult to take pictures of - they run, rarely sit still and are just too shiny!

    Reiner, the taxa shown on the site http://morwellnp.pangaean.net/cgi-bin/show_species.cgi?find_this=Nototrintus%20hackeri&image_size=0 are all Notonomus (several spp). and certainly not Nototritus or Tenebrionidae.

    Hi Reiner. If you look closely carabids (relative to tenebrionids) generally have long mandibles and (usually) thin 'filiform' antennae, and pairs of setae by the eyes, on the pronotum and along the margins (and often middle) of the elytra. Eyes are usually rounded and so finely faceted they don't appear faceted. In your image here you can see the mandibles, the thing antennae and the eye. Tenebrionidae often have coarsely faceted oval or elongate, or reniform (kidney-shaped) eyes, lack the long 'predatory' mandibles, the pairs of elongate setae, but most distinctly of all have 5-5-4 tarsi (only four 'toes' on the hind leg) compared to carabids (with 5-5-5).

    Thanks Nick. You identified a beetle of mine a couple of weeks ago tat looked like this one so I thought I'd chance it. :) I admire you for getting to genus - see Matt's confusion between different suborder/family (and I have less of a clue): http://www.bowerbird.org.au/observations/42411
