South American Species of Stridulivelia (Hemiptera: Heteroptera: Veliidae): Identification Key, Diagnoses, Illustrations, and Updated Distribution

Abstract

The genus Stridulivelia Hungerford (Heteroptera: Veliidae: Veliinae) is composed by 15 species, which are divided into the subgenera Stridulivelia s.str. Hungerford and Aenictovelia Polhemus. The nominal subgenus includes ten species restricted to South America, ranging from Colombia to Argentina. The other subgenus contains five primarily Mesoamerican species, one of which extends its distribution into northern South America. An updated identification key, diagnoses, notes, and illustrations of all South American species are provided.

Semiaquatic bugs (Insecta, Heteroptera, Gerromorpha) from Vale do Ribeira, São Paulo state, Brazil

“…Espírito Santo (Moreira et al 2010), Goiás (Cordeiro and Moreira 2015), Mato Grosso (Dias-Silva et al 2013), Mato Grosso do Sul (Floriano et al 2013), Minas Gerais (Moreira and Barbosa 2012), Rio de Janeiro (Moreira and Ribeiro 2009;, Santa Catarina (Drake 1959), São Paulo Castanhole et al 2013;Pereira et al 2015;this work Identification. Our material was identified based on the key provided by Floriano et al (2017). The two specimens above have pronotal humeral angles rounded, not spinose; stridulatory structure on laterotergites formed by a row of widely separated knob-like denticles; and hind femur incrassate, about 2.5 times wider than middle femur, with a spine on distal two-thirds of posterior margin distinctly larger than others.…”

“…Known distribution. Argentina, Bolivia, Brazil, Guyana, Paraguay, Peru, Venezuela (Floriano et al 2017). Distribution in Brazil.…”

Gerromorpha: insectos semiacuáticos, desarrollo en la última década en Colombia

“…Los trabajos sobre hemípteros acuáticos y semiacuáticos en la región Neotropical y en Sudamérica incluyen claves para la identificación de Infraordenes y familias, y estudios de distribución geográfica como los de Mazzucconi et al (2009), Cordeiro y Moreira (2015), Moreira (2015), Aristizábal-García (2017) y Moreira et al (2018). Los gerromorfos, y fundamentalmente los gérridos y vélidos, se han estudiado ampliamente; los países que descuellan en los últimos cinco años son: Costa Rica (Pacheco-Chaves et al, 2014; 2018), Panamá (Tuñon et al, 2015), Venezuela (Magalhães et al, 2019), Brasil (Rodrigues y Moreira, 2016;Rodrigues et al, 2017;Floriano et al, 2017) y Guyana Francesa (Motta et al, 2018).…”

Veliidae (Insecta: Heteroptera: Gerromorpha) from Colombia: Description of a new species and of the male of Euvelia meta Molano, Moreira & Morales, 2016

“…The genus Stridulivelia Hungerford, 1929 (Veliidae: Veliinae) is composed of 15 species, which are characterized by having the sides of the thorax with several glabrous, depressed structures, and at least the first two visible abdominal segments with transverse lateral sulci (Floriano et al, 2017). It is divided into two subgenera: Stridulivelia s.str.…”
