Type material. Male holotype (FML 02179), Provincial Route 47, 9 km E of Cabra Corral dam (25°17ʹ40.8ʺS, 65°17ʹ1.8ʺW, 947 m a.s.l.), La Viña Department, Salta Province, Argentina, 03.XI.2006, IEBI Team Cols. Male paratype (MCN-IEBI 003-000918) 1 km N of Charrillos (24°44ʹ16.8ʺS, 65°45ʹ16.8ʺW, 2238 m a.s.l.), Rosario de Lerma Department, Salta Province, Argentina, 24.II.2006, IEBI Team Cols.

Etymology. The specific name is a noun in apposition taken by the second author from “ Dobby ” of the Harry Potter saga, an elf whose nose resembles the frontal clypeal projection in this species.

Diagnosis. The species is distinguished from all other members of the genus ( G. yaculica, G. goloboffi, and G. munda) by the procursus with a smaller concave dorsal flap (Figures 7 and 8) and the anterior hooked clypeal projection (Figure 9).

Male holotype. Total length 1.16, carapace width 0.42; leg 1: (0.15 + 0.08 + 0.63 + 0.14 + 0.59 + 0.50, tarsus missing), tibia II: 0.50, tibia III: 0.45, tibia IV missing; tibia I L/d: 9. Lateral habitus as in Figure 9; entire prosoma pale ocher-yellow. Carapace without thoracic groove; distance PME–ALE about 30% of PME diameter; clypeus with an anterior hooked projection; sternum with a pair of small frontal humps (Figure 373, in Huber, 2000); chelicerae resemble those of G. goloboffi, with a pair of long, distally hooked, and frontal apophyses, with few stridulatory ridges laterally (Figure 10), stridulatory pick is a modified hair proximally on palpal femur (see arrow in Figure 11); palp in general as in G. munda, except by meaningfully different procursus, with a smaller and concave dorsal flap and slightly different distal sclerites (Figure 12), coxa without a retrolateral apophysis, femur almost cylindrical, wider distally, tibia globular, bulb as in Figure 11. Legs without rings; probably without spines, without curved and vertical hairs (most hairs missing). Opisthosoma gray, ventrally pale, with slightly darker genital plate (Figure 9).

Remark. The types of G. dobby sp. nov. come from the Yungas and Monte de Sierras y Bolsones ecoregions of the province of Salta. The holotype was collected from a humid rainforest (Yungas) considered one of the most diverse regions in the country. The Monte is characterized by a semiarid environment dominated by xerophilous plants such as Larrea sp., Prosopis sp., and Atriplex sp., and several cactus species such as Cereus sp. and Trichocereus sp. (Bertonatti and Concuera, 2000; Morello et al., 2012). This ecoregion is important for conservation, since it presents a certain grade of degradation due to natural desertification processes and anthropogenic activities (González Reyes et al., 2012).

Female. Unknown.

Distribution. Known for Salta Province, Argentina (Figure 6).
