Diagnosis. Distinguished from congeners by the large T-shaped dorsal flap on the procursus (arrow in Figure 16 ) and the slightly different embolar division ( Huber, 2000).

Distribution. G. munda ( Figure 17 ) is known from the Cerro Colorado locality of Catamarca Province ( Huber, 2000), in Laguna Brava locality of Corrientes Province ( Avalos et al., 2006), both of them from Argentina; and in Quarái, Rio Grande do Sul state, from Brazil ( Huber, 2000). Here, we enlarge the distribution of this species to the province of Jujuy ( Argentina) ( Figure 18 ).

Examined material. Argentina. Jujuy Province: Ledesma Department: Caimancito oilfield, around Oil Well 1 (23°38ʹ43.24ʺS, 64°36ʹ15.50ʺW), male, female, ( MCN-IEBI 003-000919 ), 07.VI.2011, IEBI Team Cols .

Remark. We report a new record of G. munda for the Caimancito oilfield in Calilegua National Park, of the province of Jujuy, Argentina. This new record expands the northern distribution limit of this species. This place corresponds to a mountain forest of Yungas, which is a dense and humid forest of perennial vegetation with a high biodiversity in the north of Argentina ( Bertonatti and Corcuera, 2000). Environments where G. munda and G. yaculica were found correspond to a highly modified environment due to oil exploitation activities over the last 3 decades ( Administración de Parques Nacionales and Fundación ProYungas, 2006). The presence of both species in this area might be a hint about the ability of these species to tolerate that kind of disturbance.
