Estudo taxonômico dos gêneros Oiovelia Drake & Maldonado-Capriles, 1952 e Paravelia Breddin, 1898 (Hemiptera: Heteroptera: Gerromorpha: Veliidae)

Abstract

The Neotropical genera Oiovelia Drake & Maldonado-Capriles, 1952 and Paravelia Breddin, 1898 (Hemiptera: Heteroptera: Veliidae) were studied taxonomically. The first was revised, the known species were redescribed with characters not mentioned in the original description, and four new species were described and illustrated, all of them to Brazil, totaling eight species in the genus. Oiovelia rivicola Spangler was recorded for the first time in Brazil (Amazonas and Amapá), besides expanding the occurrence area for the other described species. In Paravelia, eight new species were described and illustrated through material from seven Brazilian States (Amapá, Amazonas, Maranhão, Bahia, Mato Grosso, Mato Grosso do Sul and Minas Gerais), totaling 55 valid species in the genus. Color photographs of dorsal aspect were obtained for the following species: P. basalis (Spinola), P. biae Spangler, P. boliviana Breddin, P. bullialata Polhemus & Polhemus, P. capillata Drake & Harris, P. capixaba Moreira, Nessimian & Rúdio, P. conata (Hungerford), P. dilatata Polhemus & Polhemus, P. foveata Polhemus & Polhemus, P. itatiayana Drake, P. lanemeloi Moreira & Barbosa, P. manausana Polhemus & Polhemus, P. nieseri Moreira & Barbosa, P. platensis (Berg), P. recens (Drake & Harris), P. rotundanotata (Hungerford), P. spinifera Polhemus & Polhemus, P. splendoris (Drake & Harris) and P. williamsi (Hungerford). Three of these species are recorded for the first time in Brazil: P. plantesis, P. spinifera and P. williamsi. Moreover, the macropterous form of P. capixaba and P. dilatata are described. Finally, in order to summarize the information for species in both genera, a catalog including geographic records, synonymic list, diagnosis, and comments, are presented separately for each genus.
