Figures 6–12 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).
