Acrosternum rubescens - Female

Acrosternum rubescens is an endemic of the Canary Islands. Two of the continental/Mediterranean Acrosternum species have also been recorded from some of the islands and the identification of Acrosternum spp. is not always trivial. Stricktly following the key in the Faune de France series I would probably end up with these specimen from La Palma being some Arab species, rarely found in Greece also (due to the clearly present callosities in the punctuation of the wings) *rolleyes*. Other characters often cited (such as the colour of the pale margins being more reddish for this species as opposed to yellowish for others) also don't always hold true. I may add a more in depth analysis at some point, but not now ...
There are not many reliably identified images of this species around on the internet, so here is a starting set:
