New Genus - Euceroplatus - Setostylus - female

New Genus - Euceroplatus - Setostylus - Female
Galena Gateway Park, Jo Daviess County, Illinois, USA
May 1, 2016
Collected with a flight intercept trap near a restored prairie. 4 specimens in total.

Similar to Keroplatus, but the R2+3 ends in the costal vein and the laterotergite is bare. The longitudinal rows of tibial setae are also diagnostic. MND lists 3 species, widespread.

Moved

Different new genus
The three species in Euceroplatus in the 1965 catalog have moved to Rocetelion. In the Palearctic region, that genus is distinguished from other Keroplatini by the combination of R4 ending in C, laterotergite bare, mediotergite uniformly sclerotized (vs. "with triangular membranous area at base" in Heteropterna), tibial setae in regular rows on at least apical 1/3, hind tibia with setae in regular rows only on apical 1/2 to 1/3 ("almost entire length" in Setostylus), and "scutellum with marginal hairs short, in several rows" (vs. "long, in one row" in Setostylus). See the key by Søli, Vockeroth, and Matile (2000).

It looks like your tibial setae are in regular rows the whole length of the hind tibia. Can you check the scutellum?

There is one named Nearctic species of Setostylus, S. bellulus (Williston, 1900) known from North Carolina south to Brazil.

 
Setostylus
The hair rows extend the entire length of the tibiae and the scutellum has a single row of marginal hairs which appear relatively long. I've added a photo.

Looks like Setostylus is getting a bit of a range extension. Thanks for checking my ID.
