Click Beetle

Hi Andy,
This is definitely a Beetle, but beyond that, we are stumped.  Generally we are able to at least provide a family for beetles, but there are so many physical attributes that are distinctive on this beetle that we have not seen combined in this manner.  The pectinate (see BugGuide) are probably the most distinctive feature, but the spined thorax and narrow waist connecting to the abdomen is also quite unique.  Many beetles in the superfamily Elateroidea (See BugGuide for North American examples) have similar antennae and thoracic features, including some of the Click Beetles in the family Elateridae.  At first glance, we thought this might be a Prionid, but the thorax structure seems to negate that possibility.  We need additional time to research and perhaps one of our readers will be able to assist in this challenging identification.  We could not locate it on ThaiBugs.  Can you recall the size of this creature?

Unknown Beetle from Thailand

Immediate Update:
After posting we looked again at the ThaiBugs site and found a Click Beetle in the family Elateridae that looks close.  It is “unidentified and in need of a shave” and pictured as a thumbnail near the bottom of the page.

Daniel:
Yes, a click beetle!  I believe this one is Oxynopterus mucronatus, or at least something very closely related.  Thanks for sharing!

Thanks Eric,
We found matching images on Project Noah and the Click Beetles of the Palearctic Region website.

Hi daniel was about an inch long. dificult to gauge the with from memory.But remember being fascinated by the antenae type and size,which was noticably wider than the body.
