“…In Arachnida (Arthropoda: Chelicerata), the taxonomic identification for Araneae followed Platnick & Shadab (1982), Coyle (1986), Goloboff (1995), andRamírez (2003); for Solifugae we used Kraus (1966), Muma (1971), andMaury (1987); and for Scorpiones, we followed Ojanguren-Affilastro (2002, 2005, Ojanguren-Affilastro & Ramírez (2009), and Ojanguren-Affilastro et al, (2007a, 2007b. In Insecta (Arthropoda: Mandibulata), the taxonomic identification followed Peña (1966Peña ( , 1971Peña ( , 1973Peña ( , 1974Peña ( , 1980Peña ( , 1995; Snelling & Hunt (1975), Cigliano (1989), Cigliano, Ronderos, & Kemp (1989), Chiappa, Rojas, & Toro (1990), Artigas (1994), Estrada & Solervicens (1999), Elgueta, Camousseight, & Carbonell (1999), Roig-Juñent & Domínguez (2001), and Pizarro-Araya & Jerez (2004). It should be noted that some taxa (e.g., Diptera and Hymenoptera) were taxonomically identified only at the level of morphotype/family due to the poor taxonomic knowledge of these groups in the area.…”
