Abstract
The first Argentina records of four species of biting and predaceous midges (Diptera: Ceratopogonidae) are provided from the Iberá wetlands in Corrientes Province: Forcipomyia (Euprojoannisia) unica Bystrak and Wirth, Echinohelea blantoni Wirth, Neobezzia fittkaui Wirth and Ratanaworabhan and Paryphoconus grandis Macfie. This is the first record of the predaceous midge genus, Echinohelea Macfie, from Argentina.
Highlights
A recent survey of aquatic insects was conducted in one of the largest wetlands in South America, the Esteros del Iberá in the Argentinean province of Corrientes
We provide a brief synonymy for each recorded species, their previously known distribution, collection data and other relevant information
25 species are known in the New World, 17 species are known from the Neotropics (Borkent and Spinelli 2007), whereas 15 species have been recorded from the Nearctic region north of Mexico (Borkent and Grogan 2009)
Summary
1978: 44 (male, female; Florida, Bahamas); Borkent and Wirth 1997: 32 (in world catalog); Borkent and Spinelli 2000: 14 (in catalog of species south of USA; distribution); Borkent and Spinelli 2007: 49 (in Neotropical catalog; distribution); Borkent 2011: 32 (online catalog). At light, 1 male, 2 females (MLP). 25 species are known in the New World, 17 species are known from the Neotropics (Borkent and Spinelli 2007), whereas 15 species have been recorded from the Nearctic region north of Mexico (Borkent and Grogan 2009). F. unica is the only species with a single spermatheca, and our record from northeastern Argentina significantly extends its geographic distribution southward
