Curicta granulosa De Carlo, 1951

( Fig. 18 )

Curicta granulosa De Carlo, 1951 : Revta. Inst. Nac. Invest. C. Nat., C. Zool., 411–412.

Material examined. Laguna Iberá RS: 1 ♂, 1 ♀, Lobo Cuá Stream, 28°32’37.14’’S, 57°12’3.89’’W, 2.xii.2012.

General distribution. Colombia, Venezuela, Brazil, Peru, Bolivia, Paraguay ( Moreira et al. 2011b). Argentina: Corrientes (this work).

Habitat. This species has been collected from pools, marshy ponds, lagoons and ditches with marginal floating vegetation and bottons with plant debris, and from rivers ( Roback & Nieser 1974; Keffer 1997; Melo & Nieser 2004).

At the INR, specimens of C. granulosa were collected from the margins of the Lobo Cuá Stream, exposed to sunlight and with dense vegetation ( Fig. 17 ).

Remarks. The neotropical waterscorpion genus Curicta includes 16 species ( Keffer 1997), five of which occur in Argentina ( Coscarón 2017). The collection of C. granulosa from INR represents the first record from this country, and extends the known range of this species from Paraguay to northeastern Argentina. The following combination of characters distinguishes C. granulosa from C. bonaerensis ( Berg, 1879) , C. borelli , C. carinata Kuitert, 1949 , C. grandis De Carlo, 1951 and C. pelleranoi from Argentina: profemoral sulcus with two teeth on either side and with sulcal teeth distally; vertex usually with pronounced carina; and protibia usually with a dark, medial annulus.
