Kansas Ent. Soc., 23–24. Paravelia rotundanotata : Polhemus, 1976 : J. Kansas Ent. Soc., 512. Material examined. Itatí RS: 1 ♂ , Corriente River , 28°44.18’S , 58°8.70’W , 30.iii.2014 . General distribution. Brazil ( Rodrigues et al. 2014 ). La Plata ( Argentina ?) ( Coscarón 2017 ). Argentina : Corrientes (this work). Habitat. Very little information exists regarding the biology of P. rotundanotata . Hungerford (1930) described this species from “La Plata” and Brazil ( Minas Gerais state ) without any mention of habitat characteristics. This species has been recorded from a river ( Rodrigues et al. 2014 ). At the INR, only one specimen of P. rotundanotata was collected in the Corriente River , in open water surface beside emergent vegetation, in shaded places ( Fig. 12 ) . Remarks. The genus Paravelia contains 49 species, all of which are confined to the Neotropical region ( Polhemus et al. 2019 ; Polhemus 2021 ). So far, only four species of Paravelia had been recorded from Argentina ( Coscarón 2017 ). The collection of P. rotundanotata from INR represents the first reliable record from Argentina , as this species was described by Hungerford (1930) from “La Plata” (and Brazil ) without any mention of the country, and the first record of the genus Paravelia from Corrientes Province. This record extends the known range of this species from central-west and southeast Brazil to northeastern Argentina . The following combination of characters distinguishes P. rotundanotata from P. anta Mazzucconi, 2000 , P. paxilla ( Drake, 1957 ) , and P. platensis ( Berg, 1879 ) from Argentina : head, thorax and abdominal laterotergites with small dark spinules; antennae dark, with segment IV noticeably lighter; and males with a distinct horn-like expansion basally on the proctiger.
