oxyjack, you mean Aspisoma lineatum ?

I just leave the noah site for some hours and all this happens ! :>)

Thanks oxyjack and bayucca for the nice topic. Just to finish it, I can say, without doubt, it´s a firefly because I turn it upside down and see the light organ. Sorry, no picture.

Fantástico

Cool!

Bayucca, you found it! It's in the first paper you cited!

Yes, the body shape threw me off. I've seen more tropical roaches with that shape than fireflies. Considering that its head is concealed by its pronotum, a characteristic of the Lampyrid family (fireflies), I'd say yes, this is probably some sort of firefly.

Hmm, now as you tell this I see the differences. So this might be a Lampyridae?
Thanks for the lecture! I am glad that you first also thought of a cockroach ;-)...

Actually, I think Rubens is right. If you look closely at the wings, they don't have any veins. So these are actually elytra, which indicates a beetle, not a cockroach. This roach is very similar in appearance, but notice the veins on the wings: http://www.thenighttour.com/roach_canopy...

I also think this is a Blattodea, some kind of a cockroach.
