Nephrocerus acanthostylus
Nephrocerus acanthostylus is a species of big-headed fly (Diptera: Pipunculidae) described by Skevington in 2005 as part of a revision of Nearctic Nephrocerus. The species was one of four new species described from the Nearctic region, with diagnostic characters including distinctive male and female genitalia. As with other members of the genus, it is presumed to be a parasitoid of other insects, though specific host records for this species have not been published.
