Scymnine coccinellid? - Stethorus punctillum

Scymnine coccinellid? - Stethorus punctillum
Nashua, Hillsborough County, New Hampshire, USA
April 19, 2007
Size: 1.5 - 1.6 mm
Only one of this species found so far among thousands of other beetles from at least 23 other families (plus many other arthropods) by pawing and sifting through flotsam from a substantially swollen catchment basin after several days of heavy, non-stop rain.

The abbreviated antennae and broad oval, very convex shape say Coccinellidae to me and the fuzzy vestiture is reminiscent of the scymnine subfamily. I would be delighted to be wrong however :-)

Moved from Stethorus.

Stethorus punctillum
The postcoxal line extends beyond the midline of the sternum; in the Eastern U.S. that means S. punctillum.

 
Thank you, Abigail.
I'll move it and create a species folder for it in my private image collection.

Moved
Moved from Ladybird Beetles.

 
Thanks for genus, Belov.
I had tried once to flesh out the taxonomy of this family but was not supported by others on the site. I see you were able to sneak in a troublesome tribe :-)

Coccinellidae
In the area of Scymninae - not Scymnus though. Identifiable if I put my mind to it, but not today.

 
Stethorus?
any chance this is Stethorus? A walk through Gordon's reference (1) seems like Stethorus might fit (size, punctation, pubescence, etc., although the overall shape from Jim's photos seems move elongate than the Stethorus images I've seem - could be live vs. pinned difference) From Gordon distribution maps and UNH database, looks like there's two possible species: S. punctum (type photo here), and S. punctillum (described as unintentionally introduced from Europe)

 
Thanks
for your confirmation, Don. I'll leave it at family for now
