  1. Hi Ruth, I have added Gminatus wallengreni and Gminatus australis to our JD repository as Q&D stubs. It seems to me your photo might actually more likely show G. australis, but I'm not 100% sure about the true diagnostic characters for both.
    I'll ID it as australis for now, based on the red femora on the fore legs, but will search a little more ... Cheers, Arp

    P.S. Ruth, you write: "The ventral abdomen is also black.". Is that your own observation on this individual or did you copy that from a species description of Gminatus wallengreni ?!?

    1. My own observation. Thank you for all of this input/help. Posted 23 days ago
      1. Very interesting - thanks for answering that! The black ventral side of abdomen supposedly is a good character for Gminatus wallengreni, but in all images of that species that I more or less trust the ID of the legs are completely black - in G. australis I seem to see both black and red femora ... so ... back to the drawing board.

        1. I noticed that as well on my journey trying to ID this. Shall we go for red forelegs, or black abdomen ha ha. Is there a possibility that colours change as the insect matures? For example, I noticed the tubercles on the pronotum have not turned fully black on this specimen. Posted 23 days ago
          1. Not sure if it is possible to ID these (yet), but I'm still working on it, but need to do it in scarce time at night when I can concentrate on reading. These seem to be _very_ variable in colour (extensiveness of black) on head, pronotum and legs. Especially australis has been described many times as new species that were later sunk into synonymy, but all the descriptions provide clues to the variability of the species. Still need to chew on that for a while ... Posted 23 days ago

Gminatus australis (Erichson, 1842) is an Assassin Bug (Reduviidae) in the subfamily Harpactorinae, native to Australia. It can be easily confused with Gminatus wallengreni Stål, 1859
