Apt*opus gra*cilis

is the only Apto*pus species listed on the BISON site for New Mexico and on the CUMuseum for Colorado.

(Asterisks hide these terms from site's search function so this image is not shown in searches for those unverified names.)

Moved from Athoinae. See comments by Cardiophorinae specialist Hume Douglas, placed erroneously (along with mine) on the Info page for Athoinae.

On second thought, I'll paste them here:

"This beetle belongs to the genus Aptopus of subfamily Cardiophorinae.
For confirmation of this (on the original specimen) check whether the tarsal claws are comb like and the pronotum has the lateral ridge incomplete or absent. If it fits those 2 criteria, then it is definitely Aptopus.

Aptopus sp.

While the jagged posterior margin is typical in both Horistonotus and Aptopus, the shape of the pronotum is more typical of Aptopus. The pictures of Aptopus (Horistonotus) pullatus (Arizona) on the Harvard Type Database are an excellent match for this specimen.

Thank you, Dennis.

This poor fellow has been bounced around quite a bit ;-)

Moved from Dalopius.

Two Dalopius species

are presently listed for New Mexico: D. fusca*tus and D. lat*eralis, neither of which was I able to find depicted on the Web..

I must say that after viewing a number of other Dalopius sp. images, I saw none with the jagged-edge pronotum that this one has. In fact, most sport a very acute point on the rear angle of the pronotum.

What features distinguish this one as Dalopius?

Thank you, Boris.

I've moved it to genus page for now. The New Mexico checklist site is down so I can't check for species possibilities at this time.
