<I>Hydrellia bicarina,</I> n.sp. (Diptera: Ephydridae), a leafminer in southern watergrass

Abstract

The species Hydrellia bicarina, n.sp. originally misidentified and described as Hydrellia spinicornis Cresson by Deonier (1971) is redescribed and illustrated. This species was first collected on and reared from Southern Water Grass Luziola fluitans (Michaux) growing in shallow baytree swamps of southern Mississippi by Deonier (1971). Based on the male and female genitalia and its natural history, this species is a member of the Hydrellia griseola species group.
