Hi Tom,

Do you still have this specimen? If so can you take a very careful look at the hind tibial spurs? I'm thinking this might be E. morio. I think morio has 2 apical tibial spurs on the metathoracic legs. The elytral strigae here seem rather more narrow than those I have seen on any E. strigosus I have encountered.

Thanks.

 
Close up added
Jeff, I think I see the 2 tibial spurs in the close up. So does that make this E. morio?

 
Yup.
Keys to E. morio.

 
Wow...
that was faster than Jimmy John's!

My eucinetid keys are down at the lab. I should be down there by midweek at the latest. If I remember correctly, I think the 2 apical metatibial spurs are what separate morio from the other Eucinetus species.

Thanks for the closeup. Definitely 2 spurs.

Hi Tom
Been doing some reseach in AM. This is a Eucinetus sp. (Nycteus lacks the transverse lines). Based on color and location, this is most-certainly E. strigosus! Nice!

Eucinetidae
Eucinetus or Nycteus. I dont have a ton of experience with this family.
