It’s refreshing to come across genera that are easily diagnosable.
This is Aloconota, an athetine (maybe, haven’t looked at their naughty bits) that may be collected in debris in riparian areas. Aloconota are unique in having empodium (that elongate seta-like projection that grows between the “toes” or claws of the beetle) that are longer than the length of pretarsus, giving them the appearance of having three claws at low magnification.
So far I have not seen many in collections and I have never collected them myself. I don’t think they’re too widespread, they may be locally abundant.
