bolivian cockroach identification

[insectloving]

Hi!
I've found this nice cockroach in Bolivia, in rocks at 2000m. I would like to know the species, or if it's not possible the genera or family. I don't know cockroaches except the communs, and if someone have a family identification key or something like that, I'm interesting !
Thanks for the help ! :)

Wow, what an unusual cockroach! It belongs to the family Blaberidae, subfamily Blaberinae and it looks like it is probably closely related to the genus Blaberus - possibly an unnamed species and even genus. It is strange that it has reduced wings. Perhaps this is an adaptation for living at relatively high altitude where it is cool and wet? What is the climate and habitat like where you found it at 2000m in Bolivia? Is it cloudforest?

Thanks for the answer ! Very interesting :)
No, it is not a cloudforest where I found it: on the contrary, in a dry valley, in "walls" of rocks built by the population with rocks of cultivated fields. The temperature was like 15-20°C inside the walls (can go up to 30°C above the rocks under sun, and in the winter, the temperature can decreased until 6°C before sun rise). The humidity was about 50%.
If you need some caracteristics of the cockroach to best identify the species, tell me !

I know nothing in terms of proper identification, but I agree it looks related to Blaberus spp. What I do want to know is if you have pictures of males? Do they have reduced wings too?

Hello, thanks for your interest. Yes, it is a female. And yes, males have reduced wings too ! And I agree, it seems Blaberus spp. :) A new species :rolleyes: ??
