Discomyzinae

Psilopa polita, copyright Christophe Quintin.


Belongs within: Ephydroidea.

The Discomyzinae are a group of shore flies with pectinate aristae and large prescutellar acrostichal bristles (Mathis 2010).

Characters (from Mathis 2010): Arista pectinate; reclinate fronto-orbital seta usually inserted behind larger proclinate fronto-orbital seta; median facial area and lower facial margin without setae; facial setae inserted in more or less vertical series, parallel with parafacial setae; prescutellar acrostichal setae large (subequal to posterior dorsocentral seta), inserted widely apart (distance between them subequal to that between either prescutellar and the posterior dorsocentral seta on the same side), usually in front of intra-alar seta.
