Abstract
SILVESTRO, Violeta A.; CARRARA, Rodolfo and FLORES, Gustavo E.. Redescription and biogeographic considerations of two species of Scotobius (Coleoptera: Tenebrionidae) from mountain environments of central Argentina and Chile. Rev. Soc. Entomol. Argent. [online]. 2012, vol.71, n.3-4, pp.191-202. ISSN 0373-5680.
The Neotropical genus Scotobius Germar (Tenebrioninae: Scotobiini) comprises 61 species distributed from central Peru and southern Brazil to southern Argentine and Chile. In this contribution two species of Scotobius: S. punctatus Eschscholtz, 1831 and S. andrassyi Kaszab, 1969, that inhabit in western San Juan, Mendoza, and Neuquén provinces (Argentina) and in central Chile, along the “Cordillera de los Andes” and extra-Andean mountains in Argentina, are revised. Redescriptions using new morphological data and photographs of habitus and pronota are provided. This article informs about the geographic distribution, altitudinal ranges and the biogeographic provinces that these species inhabit. A predictive model of species distribution is presented to propose hypothesis about the factors that influence the space distribution and the allopatry of these two species.
