Gerromorpha y Nepomorpha (Insecta: Heteroptera) del Parque Provincial Salto Encantado del Valle del Cuñá Pirú, Provincia de Misiones, Argentina

Abstract

A preliminary list of the species of semiaquatic and aquatic Heteroptera occurring in the Parque Provincial Salto Encantado del Valle del Cuñá Pirú is presented. Thirty species included in 13 genera and five families of Gerromorpha and 26 species belonging to 15 genera and six families of Nepomorpha were recorded; only 16 species had been previously cited from the park. Ten species and one genus are reported from Argentina for the first time: Microvelia argentata Nieser & Alkins-Koo, Microvelia braziliensis McKinstry, Microvelia limaiana Drake, Rhagovelia janeira Drake, Rhagovelia lucida Gould, Rhagovelia paulana Drake (Veliidae), the genus Cylindrostethus, with C. palmaris Drake & Harris (Gerridae), Curicta carinata Kuitert (Nepidae), Neotrephes lanemeloi Nieser & Chen, and Neotrephes usingeri China (Helotrephidae). Twenty-four species (18 of Gerromorpha and six of Nepomorpha) and five genera (Hebrus, Paravelia, Platyvelia, Cylindrostethus and Curicta) are reported from Misiones Province for the first time. The most diverse families included Veliidae (16 species), Gerridae (9), Naucoridae (7), Notonectidae (6) and Corixidae (5). The diversity of species inhabiting in the Parque Provincial Salto Encantado del Valle del Cuñá Pirú accounts for 83% of Gerromorpha and 39% of Nepomorpha recorded from the Misiones Province. These results emphasize the value of this protected area for the conservation of biodiversity of semiaquatic and aquatic Heteroptera occurring in the province.

Aquatic insects associated with macrophytes in wetlands of the middle basin of Atrato River, Chocó - Colombia

“…Aquatic and semi-aquatic hemipterans are notable for their variety, reflecting the variety of niches they occupy, thanks to the great adaptation capacity to the environment their species have (Vanegas, 2017). This can be found in a wide variety of natural environments, both lotic and lentic, coastal and oceanic, phytotelmata and even humid terrestrial environments (Mazzucconi et al 2009).…”

Dipsas indica (Laurenti, 1768) (Serpentes, Colubridae, Dipsandinae): additional country record, list of voucher specimens, and discussion on distribution in Bolivia

“…Cylindrostethus palmaris is the most common and widespread species of the genus in the Neotropical Region, occurring from Trinidad and Tobago (Drake and Harris 1934) and eastern Colombia (Aristizábal 2002) to Argentina (Mazzucconi et al 2009b). It had been previously recorded from MG based on specimens from Januária (Melo and Nieser 2004), Perdizes, Conceição das Alagoas, Delta (Nieser and Melo 1997), Mariana (Souza et al 2006), Conselheiro Lafaiete, Carmo do Rio Claro, and Alfenas (Nieser and Melo 1997), and it is herein recorded for the first time from Ouro Preto.…”

“…Heteroptera (Insecta, Hemiptera), or true bugs, is a group of insects with worldwide distribution, which is more diverse on the tropics (Mazzucconi et al 2009a). It comprises seven infraorders, of which Gerromorpha and Nepomorpha are intimately related to water bodies of all continents, except for Antarctica (Nieser and Melo 1997;Polhemus and Polhemus 2008).…”
