bethylid - Laelius pedatus
Copyright © 2020 Steve Scholnick

bethylid - Laelius pedatus
Rockville, Montgomery County, Maryland, USA
June 20, 2020
Size: forewing 1.7mm
This one keys out to Laelius using Evans' 1964 key (1). I don't have access to his 1978 paper . The ID is consistent with Jongok Lim's comment that Laelius has "long hairs (setae) on the body."

FWIW, I tried Muesebeck's 1939 paper where it appears to key out to L. tricarinatus which Evans and Nearctica both say is a synonym of L. pedatus. However, Evans notes that the Muesebeck's paper was intended "as no more than a preliminary treatment of the genus." I know it's missing a species described by Evans (L. simplex Evans 1978).

TIA

Moved tentatively
Moved from Laelius. But I feel like it's most likely this species.

That does seem to fit with
Mertins’ Table 1 contrasting L. utilis and L. pedatus (1) although grappling with the color descriptions always gives me fits (in this case: “lightly infuscate” vs. “testaceous” vs. “rufotestaceous” vs. “ferruginous”). The transition points between those colors seem highly idiosyncratic and open to varying interpretations. Pantone colors anyone?

pedatus?
This is a male.
It looks like antennal segment 2 is shorter than 3 (rather than equal or longer). If you agree, than this should be Laelius pedatus.

measuring on screen,
the 2 flagellomeres are just about the same size, with f3 only a very small fraction larger than f2. F2 is definitely not longer than f3 but I'd probably call them the same size.

Moved from Flat Wasps.

ID confirmed as Laelius by Dr. Wesley Colombo, Universidade Federal do Espírito Santo, from the Flickr images
