A lot of look a likes in BG, not sure which one it is - Esthesopus parcus

Moved, calling this E. parcus

after re-evaluation of the specimen

Moved from Esthesopus.

After examination of voucher specimen, it has a smallish membranous lobe on tarsomere IV (I couldn't make it out in the image). This might be a variant of E. parcus but the pronotum is distinctly narrower than the base of the elytra; all specimens of parcus I have seen the widths are equal. The genitalia and tarsal claws are very similar to parcus however. Leaving at genus-level for now to be safe.

Moved from Esthesopus mitis.

Thanks Blaine,

if possible this year I will be collecting 2-3 specimens and sending one to you, great work!

Here we go! Sorry about the premature move. Esthesopus escaped my mind the first time around...then I started thinking-LOL. E. mitis doesn't have defined tarsal pads, but does have a sloping tarsomere IV.

Moved from Cardiophorinae.

I'm gonna step back a bit on this. I forgot one of the differentials :). Could you please check the tarsi/claws.

If simple tarsi but cleft tarsal claws, this is Horistonotus.
If there are membranous tarsal pads (or at least a slanted tarsomere IV) and simple claws, this is Esthesopus.

Moved from Horistonotus simplex.

Added photo,

hope it is Sufficient.

Moved Tent.

The genus is secure; should be this species but examination of the specimen is required for confirmation.

Moved from Click Beetles.
