Limnichites - Limnichites punctatus

Limnichites - Limnichites punctatus
Pitman Creek, Pulaski County, Kentucky, USA
June 30, 2012
Size: 2 mm
Found on emergent algae on partially submerged rock. Same habitat I found Pseph*enus herri*cki.

Moved from Limnichites. Found Wooldridge 1977 online, this keys to L. punctatus. However, it is very similar to L. olivaceus and care should be taken in separating them.

is it just me...
...or this one has more parallel-sided elytra -- vs rather obovate in the rest of the beetles on this page?
well, must be the angle

I'm not sure
the variety of angles makes it difficult to tell

Should also note
that the other images here (all northeastern currently) are in an area where 3 species can be found: punctatus, olivaceus, and huronicas.

yeah, that's an important caveat

chances to get it to sp.?

it may be another L. punctatus, but I'd like to see Wooldridge's revision before making that claim, and I don't have a copy...
(should definitely be either L. punctatus or L. olivaceus)
