Almafuerte remota Grismado & Carrión 2017, sp. nov

Almafuerte remota sp. nov. (Figs. 14, 15, 17 a–e, 22b) Types. Holotype male from Argentina: Mendoza: Departamento Luján de Cuyo: Álvarez Condarco, 8.IV.1979, A. Roig coll (MACN-Ar 36725). Paratypes: same data as the holotype, 1 female (together one juvenile MACN-Ar 36724); Santiago del Estero Province: Departamento Avellaneda: Colonia Dora, 1940, A. Prosen coll., 1 female (MACN-Ar 35558); same locality, VIII.1940, collector not provided, 3 females (MACN-Ar 35566, prep. CJG 1514, 1522). Etymology. The specific epithet is a Latin adjective that refers to the remoteness (about 650 km) between the two known populations of this species (Mendoza and Santiago del Estero). Diagnosis. The male of A. remota sp. nov. is similar to those of A. goloboffi sp. nov. by the relative sizes and proportions of the embolus and conductor, but differs by the shortened, more dorsally oriented RTA, the larger and curved backwards RTP, and by lacking the conspicuous ventral tegular protrusion (Figs. 14 c–f, 17 a–b); females are easily recognized by the C-shaped semicircular atria at sides of the epigynum, in where the copulatory openings are located (Figs. 15 e–g, 17 c–e).

Epigynum (Figs. 15 e–g, 17 c–e): Anterior hood nearly triangular, small, copulatory openings in lateral position, in semicircular (C-shaped) lateral atria. All other characters are common for the genus. Natural history and habitat preferences. Unknown. Colonia Dora and Santa Catalina belong to the Dry Chaco biogeographic province, but Álvarez Condarco is located in the Monte biogeographic province, although near the boundary with the Prepuna biogeographic province. Although the wide distribution of this species in distant and different biomes may result suspicious, both the Monte and Chaco share several elements, particularly in epigean arthropods (Roig-Juñent et al. 2001, 2003). Some spiders present in both regions are the nemesiids Diplothelopsis ornata Tullgren, Lycinus longipes Thorell, and the gnaphosid Echemoides giganteus Mello-Leitão (Goloboff 1995, Platnick & Shadab 1979). As for A. peripampasica, the specimens from Álvarez Condarco were collected together with many individuals of Echemoides argentinus. Other material examined. ARGENTINA: Santiago del Estero: Departamento Guasayán: Santa Catalina, 23.X.1963, M. E. Galiano coll., 1 female (MACN-Ar 35652, prep. CJG 1523). Mendoza: Departamento Luján de Cuyo: Álvarez Condarco, 8.IV.1979, A. Roig coll. 1 male (MACN-Ar 36726, Ex 18225, soft, presumably collected during molting process). Distribution. Santiago del Estero and Mendoza, Argentina.
