Abstract
In the present study, the genus Paranebalia is recorded from Argentina for the first time, with a large number of specimens collected in Nuevo, San José and San Matías Gulfs, northern Patagonia, in the years 2003 to 2007 (see Fig. 1). Although these specimens agree with the diagnostic characters of Paranebalia longipes (Willemöes-Suhm, 1875), the description and subsequent redescriptions of this species are not sufficiently detailed for a reliable identification. Hence, we provisionally named our material as Paranebalia cf. longipes (see below).
