Thanks John. In the Copromyzinae key in Pitkin 1988, the next question is about the postocular setae. A single row leads to Copromyza, Borborillus, whereas setae in at least two, usually irregular rows leads to Alloborborillus pallifrons and Crumomyia. I've appended a photo showing what I think are two rows of postoculars. Have I got that right?
