Subgenus Ephydra Fallén View in CoL
See generic synonymy.
Diagnosis. The subgenus Ephydra is distinguished from other subcongeners by the following combination of characters:
Head: Cruciate, interfrontal setae 1 pair, well developed.
Thorax: Coloration of mesonotum generally shiny, at least partially; crossvein dm-cu merged with vein CuA1 at nearly right angle.
Abdomen: Male terminalia with surstyli relatively stout and distally blunt; gonite bearing 2 very characteristically placed, subapical setae; aedeagus swollen at base or with strongly recurved basal process.
Distribution. See generic treatment.
Remarks. This subgenus comprises all species of Ephydra except E. gracilis , the only species of the subgenus Halephydra. All species of the Western Hemisphere belong to either of two species groups: the glauca and riparia groups. Both groups are represented by a single species in the geographic area being treated.
