Click Beetle - Elathous discalceatus

Moved

Sorry for the ping pong match. It took three references for me to build a confident key to these guys in the East. Our original ID of discalceatus was correct all along!

Moved from Elathous bicolor.

Sorry, right genus, wrong species. Have more comparitive material now and more confident with E. bicolor. Looks conspecific with material I received from NC.

perplexing...

I am leaning towards Elathous discalceatus. The general gestalt looks like an Athous, however, it lacks the tarsal lobes of most Athous. The only eastern Athous w/o tarsal lobes is A. rufifrons, and this specimen is clearly not conspecific with A. rufifrons I have (not does it match well with the description in Becker's 1971 revision).

It is a male, and the genitilia are of the Athous-type, but I imagine Elathous is similar in those regards.

The only key to Elathous is Van Dyke, 1932. If this is Elathous, E. discalceatus is the best match, based on distribution in the east, coarse umbilicate pronotal punctures, and pronotum sinuate past the middle.

I do not yet have Elathous in my reference collection for comparison so will dig around some more to be certain...

Elathous discalceatus?

This one is making you work to figure it out:-) At least I hope it adds something new to your reference collection.
