Checklist and distribution of semiaquatic and aquatic Heteroptera (Gerromorpha and Nepomorpha) occurring in Brazil

Abstract

Based on published information of about 200 references, 479 species of Gerromorpha and Nepomorpha have been recorded from Brazil and compiled here for the first time. Of these, 105 belong to the family Veliidae. Families Gerridae, Belostomatidae, Corixidae, Naucoridae, Nepidae, and Notonectidae contain between 44 and 61 species each. Because of their apparent inherent lower diversity or difficulty of collection and/or study, other families present at most 21 species. Of the recorded species, 47% occur solely in Brazil, 44% in Brazil and other South American countries, 7% are more distributed along the Neotropical Region, and only 2% are widely distributed in Americas. Species records from Brazil are more concentrated in the North and Southeast regions, and on Amazonas, Pará, Minas Gerais, and Rio de Janeiro states, not alone due to environmental conditions, but also because of historical factors. A high number of endemic species of Rhagovelia, Limnocoris, and Ranatra is found in the Southeast and South regions. Other groups are exclusive or more diverse in the Amazon Region, such as Lathriobatoides, Bacillometra, Cryptovelia, Darwinivelia, Euvelia, Stridulivelia, and Weberiella.

New records of Gerromorpha and Nepomorpha (Insecta: Hemiptera: Heteroptera) from South America

“…The few specimens reported here represent North and West expansions to the distribution of Euvelia lata and the confimation of the occurrence of Microvelia pulchella , the latter previously recorded without exact localities by Drake and Plaumann (1955). On the other hand, some regions of Brazil, especially the states of Rio de Janeiro and Minas Gerais, are very well studied (Moreira et al 2011). The records presented here concern the local distributions of Halobatopsis platensis , Rhagovelia triangula , Limnocoris brasiliensis , L. volxemi , and Martarega bentoi .…”

“…The main diagnostic characters at the species level include the structure and striation of the frons (the so called frontal plate), shape and structure of pronotum, colouration of body dorsum, shape of the male genital capsule, and especially, the structure of the right paramere (e.g., ANDERSEN & WEIR 2004;. Although a world catalogue or monograph of Ochteridae has never been compiled, there are several valuable revisions, monographs or catalogues dealing with faunas of particular zoogeographical regions: Afrotropical Region , POLHEMUS & POLHEMUS 2008, Palaearctic Region (POLHEMUS 1995a), Oriental Region (KORMILEV 1971, Malesia (KORMILEV 1971;, Philippines (GAPUD & SAN VA-LENTIN 1977;GAPUD 1981GAPUD , 1986GAPUD , 2003, New Guinea (KORMILEV 1971, BAEHR 1990b, Australia (KORMILEV 1971;BAEHR 1989BAEHR , 1990aCASSIS & GROSS 1995;ANDERSEN & WEIR 2004), North America (SCHELL 1943a,b;POLHEMUS & POLHEMUS 1988a, Central America (CHAMPION 1901;SCHELL 1943a,b;HECKMAN 2011;POLHEMUS & POLHEMUS 2016), and South America (SCHELL 1943a,b;NIESER 1975;HECKMANN 2011;MOREIRA et al 2011MOREIRA et al , 2019CIANFERONI 2012;CORDEIRO et al 2014;POLHEMUS & POLHEMUS 2014BARBOSA & RODRIGUES 2015). Despite the considerable progress in Ochteridae taxonomy since 1971, there are still many species awaiting description.…”
