Melanotus - Melanotus cribriventris - male

Melanotus - Melanotus cribriventris - Male
Pulaski County, Kentucky, USA
May 29, 2011
Size: 10 mm (elytra 7.5 mm)
Blaine, I think this one keys towards M. cribriventris Blatchley, unless I'm interpreting the relative lengths of 2nd/3rd antennomeres incorrectly.

Mandibular pit present, large; 2nd/3rd antennals small; elytron length is 7.5 mm; antennae exceeds pronotum by 3.5 segments and are very setose.

Moved
Moved from Melanotus.

Yes, looks good with comparitive material from GA. For some reason I was thinking the pronotal punctures were sparser but they apparently are not :)

Pronotal punctures
The description of this species in Quate and Thompson says "punctures [of pronotum] at center separated by distance equal to or less than own diameter." This was the reason for my hesitance, because they seem to be more widely spaced than that description, though I suppose antero-medially they are as described.

melanotus
Your interpretation of the characters looks good for M. cribriventris, and antennomeres II and III do look subequal from two views. The pronotal shape and density of its punctures look off for cribriventris, but I may not be remembering correctly.
I will compare with voucher material when I get home tonight, but for now looks good.
