Paravelia rotundanotata (Hungerford, 1930)

Velia rotundanotata Hungerford, 1930: J. 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.
