Blattodean

At the Las Cruces Biological Station near the Panamanian border, I found nymphs of the giant blattodean Megaloblatta blaberoides, which, until recently was considered to be the largest member of this group of insects in the world (a larger species was found in SE Asia a few years ago.)

The lacinula, a subapical lobelet on the lacinia, is present in almost all studied blattodeans but its potential homology to the dentisetae of Palaeoptera or the lamellae of apterygotes cannot be addressed at the moment.

I hate to admit, but my issue with uploading photos of blattodeans is mainly due to difficulties in identifying some of the species I photographed.
