An inordinate fondness for systematics
It looks like a wingless firefly (Coleotera: Lampyridae), those exist don't they? I've absolutely no time to go googling around.merry christmas all
Some kind of cockroach nymph? Based solely on jizz and the oval pronotum. Antennae look wrong for Blattodea but I'm not feeling inspired!!
Termite? Or insect or something?
Overall, it looks like a staphylinid beetle, perhaps an aleocharine, to me. Of course, this begs the question of why you would post it. So, it must be doing something interesting. Staphylinids seem more bizarrely diverse in their ecological associations than most beetles, but this doesn't look like any of the ant or termite associates that I've seen and I'm not having any luck googling staphylinid and any modifier I can think of. Stumped, I guess.
Yes, it sure looks like an aleocharine staphylinid and probably some kind of termitophile given its somewhat "fat" abdomen.
Tachiona deplanata of the Aleocharinae? From Mexico.
Adults and larvae of the genus Tachiona are found exclusively in the web-covered burrows of hepialid moth caterpillars, in the wood of shrubs.
At least 8 spp., this is definitely not T. monteverdensis but I can't find pics of any of the others apart from T. deplanata so it is probably one of the others like T. elegans, T. latipennis, T. mexicana, T. nitida or T. oaxacaensis.
People certainly did better here than I was expecting (and, once again, I apologise profusely for lumbering you all with such a rat-shite image). Three points to Dave (aleocharine staphylinid); two points to Leonardo (physogastry suggesting termitophile). Expect the full explanation soon.
