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, 1951Drake, C.J. 1951. New water striders from the Americas (Hemiptera: Veliidae). Revista de Entomologia, Rio de Janeiro, 22: 371-378.) 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.
