New Records of Gerromorpha (Insecta: Hemiptera: Heteroptera) from the Neotropical Region

Abstract

Gerromorpha or semiaquatic bugs have the ability to walk on the surface of the water and occupy a wide variety of habitats. They are relatively well studied in the Neotropical Region, but some species are known only from the type localities or have many gaps in their documented distributions. In this study we examined specimens housed in the National Museum of Natural History, Smithsonian Institution, and report new records for 17 species:

Aquatic and semiaquatic bugs (Insecta, Hemiptera, Heteroptera) from Toluviejo Municipality, Sucre Department, Caribbean region of Colombia

“…Platyvelia brachialis is the most common and widespread species of the genus, being found from eastern United States to northern Argentina (Perez-Gelabert and Floriano 2016). The first 2 records from Colombia are very recent, one at Norte de Santander Department, about 375 km away from Toluviejo , and the other from Meta Department, approximately 640 km southeast of our study area (Floriano et al 2017). Centrocorisa kollari has been collected from Mexico to northern Argentina (Hungerford 1948, Bachmann 1981), but has many gaps in this large area.…”

Checklist of Aquatic Heteroptera genera (Insecta: Hemiptera) from Brazilian Savanna (Cerrado Biome), with family and genera identification key

“…The genus Rheumatobates, according to moreira & camPos (2012), occurs in the states SP, SC, RS, PA, MT, MG, SP, RJ, AM, and in this work a new record was registered for GO. Floriano et al (2017) records the genus Ovatametra for the states of BA, AM and PA. In the present study, they were found in the DF (new record for the DF).…”

New records of Gerridae (Insecta, Hemiptera, Heteroptera) from northern South America

“…Literature used for specimen identification is presented in the results under each species. The geographic distribution and the map of each species are based on the literature (e.g., Drake and Roze 1954;Nieser 1970Nieser , 1993Molano et al 2005;Morales and Molano 2009;Moreira et al 2011Moreira et al , 2016Cordeiro and Moreira 2015;Floriano et al 2017) and the labels of the material examined. Photographs were made using specimens preserved in alcohol and a Leica S9I stereomicroscope with integrated camera.…”
