Ovatametra obesa Kenaga, 1942

( Fig. 20 View FIGURES 18–22 )

Ovatametra obesa Kenaga, 1942 : J. Kansas Ent. Soc., 138–139.

Material examined. Laguna Iberá RS: 3 ♀, artificial channel, 16.ii.2018. San Ignacio RS: 1 ♀, vehicle path, roadside marshland and ditches, 27°49’26.64’’S, 56°50’52.38’’W, 17.xi.2018; 4 ♂, 12 ♀, Camping Monterrey, Aguará pedestrian path, marshland, 27°52’14.10’’S, 56°52’59.70’’W, 18.xi.2018; 3 ♂, 6 ♀, Camping Monterrey, Aguará pedestrian path, long walkway, marshes, 27°52’14.58’’S, 56°52’59.76’’W, 18.xi.2018; 1 ♂, 3 ♀, Camping Monterrey, Aguará pedestrian path, flood-prone areas, 27°52’22.08’’S, 56°52’57.84’’W, 19.xi.2018.

General distribution. Colombia, Brazil, Bolivia ( Floriano et al. 2017; Moreno-R et al. 2018). Argentina: Corrientes (this work).

Habitat. This species has been found in pools, ponds, lakes, and streams and rivers which are slow to moderately fast-flowing ( Nieser 1970b; Pereira & Melo 2007; Moreira et al. 2011a; Moreno-R et al. 2018; Rodrigues et al. 2021b).

At the INR, O. obesa was collected from the densely vegetated margins of sunny marshlands ( Fig. 15 View FIGURES 14–17 ), marshes and flood-prone areas ( Fig. 16 View FIGURES 14–17 ). Occasionally this species was found in moderately shaded margins of ditches and artificial channels.

Remarks. The neotropical genus Ovatametra includes eight species ( Polhemus & Polhemus 1995). So far, only O. gualeguay Bachmann had been recorded from Argentina ( Coscarón 2017). The collection of O. obesa from INR extends the known range of this species from eastern Brazil and Bolivia to northeastern Argentina. The color pattern of the mesonotum in apterous females, with a large oval yellow spot surrounded by black on each side of the median dark band in O. obesa and a longitudinal yellow band on each side of the median dark band in O. gualeguay , differentiate the two species. Both species share the presence of a tuft of setae medially on abdominal tergum VII.
