Cymindis punctifera (LeConte)

Cymindis punctifera (LeConte) is my physical determination for this specimen which is added to the PWM synoptic set of North American Caraboidea. Thank you Margarethe.

ID holds in light of Hilchie & Ball (2024)?

just to make sure

Margarethe's physical specimen tagged 1691741

mailed to me stays with "Cymindis punctifera". It's a male whose phallic median lobe ends in a diagnostic narrow apical bulb (vs spatulate end in C. apache Hilchie & Ball). Three other C. punctifera specimens with the same data and same phallic apices were posted on BugGuide: 1691927, 1691927, 1691726.

V Belov, if specimen 1691741 were truly "10 mm" (error vs altered fresh state?), your inquiry makes good sense. However, I measured ABL 9.0 mm in the dry state for this one; two others in the series were each 8.5 mm dry. Complicating matters is that the two sibling species in question co-occur in the same microhabitats so collectors must be careful in their species separations.

Not that many "brown" Lebia

of southwest, so it should be easy to ID under scope. I already have examples of most southwestern Lebia for comparative study.

again

ithought it was tribe Lebiini but not genus Lebia

You might be right about a sibling genus of Lebia like Cymindis.

You might be right about a sibling genus of Lebia like Cymindis. I look forward to studying it. I tend to get lazy with just images, but I do deliver accurate physical determinations.
