elongate brown striated - Uloma mentalis
Copyright © 2005 Jim McClarin

elongate brown striated - Uloma mentalis
New Hampshire, USA
Size: 8.8 mm
This beetle died before I could photograph it. It's been in alcohol since probably sometime last year, possibly even back to fall 2003. It was collected somewhere in central southern New Hampshire. As you can see, it lost its hind legs and tarsi on the remaining legs.

The underside of the tibia appears to be covered with teeth, like a wire brush for a dog. What purpose do they serve?

Tenebrionidae: Uloma sp.
I finally compared a Uloma to the photo, and it seems that the specimen is a bit discolored and beatup, but it is a Uloma.

Loopback
Don, I notice that the fourth and fifth stria on the left elytrum (which is more in view) meet and close whereas I don't see this on any of my other Uloma photos. Is this taxonomically relevant?

variable
This one looks more distinct/complete than most, but it does seem to vary within the species from the apically fused portion being distinct to indistinct.

maybe
I can't see the apical third of the elytra for most of the Uloma to be sure of anything.

tenebrionidae
id say it's a teneb based on the 3 connate ventrites and concealed antennal insertions (if you were looking for a family id). I dont know what the 'teeth' are for, maybe clearing debris out of the way while the animal moves around in tight spaces like leaf litter or under bark

Thanks Keith.
I'm sure I thought it was a teneb at first, then had doubts when I got it under maginification. On your opinion I'll move it to family.
