Slime Mold Beetles - Sphindus americanus

Slime Mold Beetles - Sphindus americanus
Nashua, Hillsborough County, New Hampshire, USA
June 16, 2006
Size: 1.7 - 1.9 mm
This view has little to recommend it other than a good image of the antennal club.

Probably Sphindus
I think this is a Sphindus. Seems to be too elongate for Eurysphindus, at least in my eyes. The pronotum does not look right either. I'll be posting images of both Eurysphindus species in the near future. I'll try to get Dr. Joe McHugh to verify this is Sphindus.

 
Thanks, Jeff.
I'll look for that verification.

Moved

Eurysphindus comatulus
Finally tracked it down. Broader and "hairier" than Sphindus.

 
Thank you, Don.
I created a genus/species page for E. comatulus and moved it there.

Sphindus americanus
is the closest match among five drawings in American Beetles, and it is one of four species recorded for New Hampshire. This ID is tentative since none of the other three New Hampshire species (Odontos*phindus denti*collis, Eurys*phindus hir*tus, Eurys*phindus coma*tulus) are depicted in the entire. The over-all antennal shape is characteristic for at least several of the nine sphindid species in North America. However, a drawing of the club of E. hir*tus in American Beetles shows the second and third antennomeres from the tip being nearly equal in size, so I think that NH species can be eliminated as a possibility.

This is a new family for bugguide.

(Asterisk use is to hide species' names that are not depicted here. Otherwise bugguide's search function would show this image when someone searches on those names.)

 
Eurysphindus hirtus
Am not absolutely sure this is correct (could be the other Eurysphindus), but am sure it is not Sphindus americanus. Note the longer setae obviously in rows. Your other photo is of S. americanus.
