Humbe tenuicornis (Schaum, 1853)

Caveat to the new random selection of featured creatures - if all photographs of the randomly selected subject (Morphacris fasciata) are blurry, selecting a neighbouring species is acceptable.

And so I give you:

Humbe tenuicornis Chongwe Lusaka Zambia

Although I like this angle, I recognise that it's a little generic, so I'll be generous and give you another shot of this species:

This lovely grasshopper is:

Humbe tenuicornis
(Schaum, 1853)

Although widespread and fairly awesome, it's the only species in the genus. Which adds a level of confidence to my identification of this (African) species. 

I can't say much about it, except that it seems most common late in the rainy season and, like all known true grasshoppers, is probably primarily herbivorous. It has no common name that I'm aware of, although, as children, my sister and I referred to this (and several less abundant species) as 'dinosaur grasshoppers' because of the inflated, keeled pronotum, which was vaguely reminiscent of the hoods of Ceratopsids such as Triceratops. I did say vaguely. 



Anyway, into the taxonomy:

- Panorthoptera              
- Orthopterida                   
- Polyorthoptera                  
 - Anartioptera                        
- Polyneoptera

- Eukaryota                                                                                       


And, beyond the obligatory footnote that grasshoppers are awesome, That's All, Folks. 



As always, the Orthoptera Species File is the place to go to identify tropical orthopterans. It's strongest in the US and Europe, for which purpose-built guides can be found, but African grasshoppers are generally well covered, as are most katydids (other family groups are not as complete for their coverage of images and ranges).
