Orussidae - Orussus minutus

Orussidae - Orussus minutus
Story County, Iowa, USA
June 20, 2008
Malaise trap June 20-26, 2008, narrow wooded valley near limestone seeps and creek.
Sorry about the image quality. I don't know if it was the dark black, bumpy texture, or size of specimen. Borror & Delong say 8-14 mm long but this is smaller.

Orussus sp.
Chances are it is Orussus minutus Middlekauff, the smallest of the three eastern species. There is considerable variation in size within each species, so size is not a good criterion for species separation.

Very interesting.
Will have to check the catalog to see if there are other genera, and/or whether there is sexual dimorphism.....
