Anthia (Termophilum) fornasinii, Bertoloni 1845

So....

It's been about a... while. That's largely because other stuff (henceforth referred to as 'shizzlage') has been a-happening... and is continuing to happen, but I'm taking a break. 

Instead of going away from the computer and giving my eyes a chance to recover, I'm giving you a wonderful gift. Some hints: 

Eukaryota
  Animalia
    Eumetazoa
      Bilateralia
        Nephrozoa
          Protostomia
            Ecdysozoa
              Arthropoda
                Hexapoda
                  Insecta
                    Dicondylia
                      Pterygota
                        Manopterygota
                          Neoptera
                            Eumetabola
                              Endopterygota
                                Coleoptera

Yes, it's another beetle. We're a fraction closer to having representative samples of taxa (a tiny fraction. I'd need about twelve more up, eight or so of them weevils, before we could actually say that beetles were appropriately represented... and then, because we've already got three vertebrates up (here, here and here) I'd have to add two ray-finned fishes so that the Sarcopterygians don't steal an unfair share the show). Talking of the show, on with it: 

                                  Adephaga
                                    Carabidae (although realistically, a superfamily might be required here, these are probably the best-studied group of beetles that aren't agricultural pests)
                                      Harpalinae 
                                        Anthiitae 
                                          Anthiini

which brings us back to the more-or-less delightful:

Anthia (Termophilum) fornasinii
Bertoloni 1845
 (probably)

And - with precisely this much ado - here it is: 

Anthia (Termophilum) fornasinii, Bertoloni 1845, Chongwe, Lusaka, Zambia, November 2011

These really-quite-large beetles don't have much in the way of a common name, beyond 'Ground Beetle' or, a little more descriptively 'Predatory Ground Beetle. You point out that this heavy-bodied beetle is liable to be a fairly poor predator? 

Well... 
To give you some idea of the scale of this (Central/East African) species, that beetle held in its jaws is a reasonable sized chafer (Melolonthinae), around 18mm long - just a little smaller than a Common Cockchafer (Melolontha melolontha). 

As an interesting final point, several members of the genus Anthia are armed with Formic acid (ants are fond of this defensive chemical), with which they will spray attackers. I have to add that while I have handled these beetles on several occasions, I've never witnessed such an attack.
