Abstract Abstract

Background

Aquatic and semiaquatic Heteroptera occur on all continents except Antarctica and occupy a wide variety of habitats, including lentic and lotic water bodies, perennial or temporary. In the Neotropical Region, there is a lack of knowledge concerning the geographical distribution of most represented species, which can only be solved by the collection of specimens in under-studied areas and publication of new records and lists of species.

New information

New records are presented for eleven species of Gerromorpha and ten Nepomorpha, including first records from Venezuela (Brachymetra lata, Limnogonus hyalinus, Rhagovelia evidis, Tenagobia peruana, Limnocoris burmeisteri, L. fittkaui fittkaui, Placomerus micans, and Martarega gonostyla), the Venezuelan State of Bolívar (Cylindrostethus palmaris, R. elegans, R. tenuipes, and Ambrysus stali), the Brazilian State of Bahia (Martarega bentoi), Peru (Euvelia lata), and the Peruvian Region of Arequipa (Microvelia pulchella).

Keywords: Aquatic insects, geographic distribution, Neotropical Region, Venezuela, Brazil, Peru.

Introduction

Heteroptera is an interesting group of insects distributed worldwide, being more diverse in tropical zones (Mazzucconi et al. 2009). Most species are terrestrial, but many others are aquatic or semiaquatic, occurring on all continents except Antarctica (Polhemus and Polhemus 2008). Out of the seven infraorders of the suborder, the truly aquatic bugs (most of which live inside the water) are representatives of Nepomorpha, and primarily semiaquatic species constitute Gerromorpha and Leptopodomorpha (Nieser and Melo 1997, Polhemus and Polhemus 2008). The Neotropical fauna of aquatic and semiaquatic Heteroptera is relatively well-known (Polhemus and Polhemus 2007) and there has been increasing interest by research groups from Colombia, Brazil, and Argentina (Moreira 2015). Despite this, several undescribed species occur in the region and there are significant areas which have never been sampled (Polhemus and Polhemus 2007, Polhemus and Polhemus 2008, Moreira 2015). We present new records for 21 species based on material recently collected from understudied areas in Venezuela, Brazil, and Peru.

Materials and methods

Most of the material cited below was collected as part of the project "Biodiversity of river corridors of tropical forests: current status, impact of anthropogenic activity and the prospect of recovery" in Canaima National Park, Bolívar State, Venezuela. The park is part of the Venezuelan Guyana Region, has more than 30000 km2, and was considered a World Natural Heritage Site by UNESCO in 1994 (World Heritage Committee 1995), but the local fauna of water bugs has never been efficiently explored. Material examined is deposited in the Department of Biology and General Ecology, Faculty of Ecology and Environmental Sciences, Technical University in Zvolen, Zvolen, Slovakia (TUZVO). Main information about collecting localities is presented in Table 1. The known geographical distribution of each species is provided mainly according to ​Moreira (2016)​. New records are followed by an exclamation mark. Photographs showing some of the collecting localities are provided on Figs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18.

Discussion

Currently, the knowledge about Gerromorpha and Nepomorpha from Venezuela is based almost entirely on original descriptions of species or records scattered throughout the literature. A checklist of species from the country does not exist, which can be explained by the lack of local taxonomists and by the difficult access to some areas of the country. Based on material from Canaima National Park and its vicinity, it was possible to fill gaps in the geographic distributions of Brachymetra lata, Cylindrostethus palmaris, Limnogonus hyalinus, Rhagovelia elegans, R. tenuipes, and Ambrysus stali. Expansions to the distribution limits of R. evidis (North), Tenagobia peruana (North and East), Limnocoris burmeisteri (Northwest), L. fittkaui fittkaui (North), Placomerus micans (North and West), and Martarega gonostyla (Northwest) were also detected. In turn, Rhagovelia yanomamo and Ambrysus montandoni had already been recorded from localities situated in close proximity to the park and were represented in our samples.

Peru has a similar state of knowledge about aquatic and semiaquatic Heteroptera, also due to the lack of specialists and existence of unexplored regions. 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.
