A new species of Oiovelia from Colombia, with notes for other three species of South American Veliinae (Heteroptera: Gerromorpha: Veliidae)

Abstract

The new species Oiovelia shepardi is described based on macropterous specimens from the departments of La Guajira and Antioquia in northwestern Colombia, and is compared to its presumed closest relative. The female of Paravelia cunhai Rodrigues & Moreira, 2016 and the male of P. polhemusi Rodrigues, Moreira, Nieser, Chen & Melo, 2014 are described for the first time. The specimens of the two species of Paravelia Breddin were collected in waters inside caves in the State of Pará, northern Brazil. Further, the micropterous form of Steinovelia vinnula (Drake, 1951) is described, compared with S. virgata (White, 1879), and new distributional records are provided. Illustrations and a geographic distribution map of all species treated here are presented.

New records of cave-inhabiting Gerromorpha (Insecta, Hemiptera, Heteroptera) from Brazil

“…The aim of the present study is to provide new information on the geographic distribution of Gerromorpha in Brazilian caves, which only recently revealed to house a remarkable diversity of semiaquatic bugs (Moreira and Campos 2012;Taylor and Ferreira 2012;Rodrigues et al 2014;Cordeiro and Moreira 2015;Floriano and Moreira 2015;Moreira 2016a, 2016b;Polhemus and Ferreira 2018;Rodrigues and Álvarez-Arango 2019;Monte and Bichuette 2020).…”
