Dichtha inflata, Gerstaecker, 1854 (Probably) and Namibian Independence.

So tomorrow (well, today, if you're further East than Jakarta), is the day that Namibia celebrates its independence from South Africa, fully realised in 1990.

Which I thought I would commemorate by putting up a vaguely Namibian photo, which becomes a touch more complex when I note that I have never actually been to Namibia.

This shouldn't really be a problem - the Caprivi strip takes up a significant chunk of Zambia's southern border, and a fair number of species occur widely in both countries. The issue arose because I wanted something that more specifically said 'Namibia!' - an Icon, if you like. The obvious choices are therefore on Namibia's coat of arms: Oryx (or Gemsbok) and African fish eagle. The former I've only managed to photograph in captivity, and the latter, if I had a good enough picture, would be reserved for Zambian independence.

Another problem was that these are both vertebrates, as have been my last three posts, and I can get a little sick of backbones from time to time.

But then it struck me:

Photographed in New Kasama, Lusaka, Zambia in March 2013, using Olympus E-420 with Zuiko 40-150mm lens and 2 KOOD magnifiers.

This is a member of a group of animals that I really think of when I think of Namibia. In Afrikaans, it's a Toktokkie, one of a number of darkling beetles who tap their abdomens against the ground to attract mates.
Although representatives are found across much of Africa, the association of a number of endemic and near-endemic species with the Namib desert has made them an icon, for me at least, of the region.

Without further ado, then, this is (almost certainly):

Dichtha inflata
Gerstaecker, 1854

However, it's worthy of note that this follows a rather convoluted method of identification, and so I can't actually cite a source... sorry...

Chiromantis xerampelina
Peters, 1854

Also known as the Grey Tree Frog, the African Foam-Nest Frog, the African Grey Foam-Nest Tree Frog... they go on and on.

Chiromantis xerampelina, Chongwe, Lusaka, Zambia

This small, unimposing frog may look unremarkable, but believe you me, it isn't. Its nesting habits are well covered elsewhere, and so we won't discuss arboreal orgies, but instead talk of its extraordinary physiology.

In many areas in central and eastern Africa, this frog is the only frog you will find away from water in the dry seasons. Toads, themselves very tolerant of dehydration, will still usually remain close to some permanent body of water, even if it's only a dripping faucet half a mile away, but this frog will endure months without anything to drink, or anything to eat; it can tolerate direct tropical sunlight for fourteen hours without drying out of getting a raised temperature, it barely urinates - I would be more specific, and this paragraph will eventually be edited to be so, but my books are in storage, so for now, you're only getting the bits I can remember. Sorry, and all that.

Anyway, it is most readily identified by its unusual digital arrangement among local frogs - having two toes pointing in each direction. Its colouring is not reliable, as it can vary from a very pale grey to a brown so dark it's almost black, with or without marbling.

That's all, folks.... at least until I get my books back...
