Beetle - Silvanus muticus

Beetle - Silvanus muticus
Tippecanoe County, Indiana, USA
March 30, 2007
Size: ~ 3 mm
This is very similar to my previous post, but has spines at the anterior angles of the pronotum.

Moved from Silvanus. Tarsi unlobed --> S. muticus.

Beetle - Silvanus
I'd say it is either Silvanus muticus Sharp or the very similar Silvanoprus angusticollis (Reitter), an Asian species introduced into the eastern U.S. In Silvanus, tarsomere 3 is simple. In Silvanoprus it is lobed. Hard to see except under a microscope.

I'll have a look when I get a chance and post a better image as well.

have you had that chance, Brad?


prominent anterior edges
. . . of pronotum point to Silvanus, but do not exclude Silvanoprus.


Strikes me as being a Silvani
Strikes me as being a Silvanid... maybe even Silvanus
