Taxonomia de Leptohyphidae (Insecta: Ephemeroptera) da Amazônia Central

Abstract

Despite the wide distribution of Leptohyphidae in Brazil the number of known species in the family is still incipient. Specially in the North region, little is known about this family, being only six species recorded there: Amanahyphes saguassu Salles & Molineri, 2006 (AM), Leptohyphes populus Allen, 1973 (AM), Macunahyphes australis Dias, Salles & Molineri, 2005 (PA, RR), Tricorythodes rondoniensis Dias, Cruz & Ferreira, 2008 (AM, RR), Tricorytopsis bahiensis Dias, Salles & Ferreira, 2008 (AM, RR) and Tricorythopsis yucupe Dias, Salles & Ferreira, 2008 (AM, RR). With the objective to contribute with the knowledge on Leptohyphidae in the North region, particularly the Amazon state, specimens from two municipalities were analyzed: Manaus (Adolpho Ducke Forest Reserve) and Presidente Figueiredo. Three new species were described, two in the genus Tricorythopsis Traver and one in Tricorythodes Ulmer and, a key to identify genera and species known from the North region is presented. Tricorythodes ocellus Allen and Roback, 1969 is recorded for the first time in Brazil. With these results, the number of known species in the Leptohyphidae family in North region of Brazil increase from six to 10.
