Pseudothericles jallae jallae (Griffini, 1897); or the importance of angle.

After a month or so of crouching down to see yet another Aiolopus thalassinus or generically brown cricket nymphs, it becomes very easy to dismiss something small and dully coloured that hops away as you walk, even in such promising locations as game-ranches on the outskirts of Lusaka, Zambia.

Sometimes, though, that tiny thump and that brownish blur reward your attention with this:

I'd like to be able to offer common names beyond the suborder-inclusive grasshopper, but none of my books are being helpful there, and I get more results on Google searching for my own name in quote-marks than I do searching for the family.

So we'll have to work at it. It is actually called:

Pseudothericles jallae jallae
(Griffini, 1897)


The basic roots there are Pseudo (or false) and Thericles, from a related genus. Breaking that down, I'd take a wild stab at it being an extension of a greek word for summer, θέρος (Theros), so we'll say that the genus Thericles are 'Summer Hoppers', and our own Pseudothericles becomes a false summer hopper. 

Then comes jallae. Now, if we play with google for a minute, jalla could be from the arabic:
  جلا
 (dj-U-ll-ah), which has a number of meanings, mostly to do with cleaning, fixing or solving, but I rather suspect that it was named for the Italian missionary Luigi Jalla, who was certainly involved with reptiles and amphibians (keeping brief my comment on how poorly those groups fare when they encounter the religious), and probably also made himself known to the entomologists working in the region. 

That would make the aforementioned Pseudothericles jallae jallae's brand new 'common' name: 
Jalla's False Summer-hopper (nominate ssp.)

 And while I'm not going to translate that all into Chewa right now, the more generic Chewa/Nyanja words for grasshopper include: Chikhwiya, with or without the Chi, Thuli and my personal favourite, Tsokonombwe

So another view of our little tsokonombwe:

 And with that, it belongs, phylogenetically speaking, to: 

- Pseudothericleini
- Thericleinae          
- Thericleidae           
- Eumastacoidea          
- Acridomorpha

- Orthopterida                           
- Polyorthoptera

- Eumetazoa                                                                   
- Animalia                                                                         
- Eukaryota                                                                           


And that, unless I'm very much mistaken, is all, folks!



As per usual, the place to go when trying to identify tropical Orthoptera is The Orthoptera Species File. It's not as user friendly as it might be, but it's free and has extraordinary coverage of images of type specimens, lists of relevent texts - and links to those available online - and also distribution maps and even the option to search by location. So it's basically one big win.
