The genus SphingonotusFieber, 1853 is one of the most species-rich grasshopper genera in the world. We studied the morphology of c. 1000 individuals from the Iberian Peninsula to review the taxonomy of the genus and its relatives. Moreover, we inferred a molecular phylogeny of the Iberian Sphingonotini based on two mitochondrial genes. The Iberian and north-west African Sphingonotini comprise two recent radiations, within which the genetic relationships are not fully resolved. A multivariate ...The genus SphingonotusFieber, 1853 is one of the most species-rich grasshopper genera in the world. We studied the morphology of c. 1000 individuals from the Iberian Peninsula to review the taxonomy of the genus and its relatives. Moreover, we inferred a molecular phylogeny of the Iberian Sphingonotini based on two mitochondrial genes. The Iberian and north-west African Sphingonotini comprise two recent radiations, within which the genetic relationships are not fully resolved. A multivariate morphometric analysis showed that S.azurescens (Rambur, 1838) and S.morini (Defaut, 2005) can be clearly discriminated, supporting their species status. Based upon the combined data, the genus GranadaKocak & Kemal, 2008 is synonymized with SphingonotusFieber, 1853 and its type species re-assigned to Sphingonotus imitansBrunner von Wattenwyl, 1882 comb. rev. The data also supported species rank for Sphingonotus lusitanicusEbner, 1941 comb. rev.Oedipoda callosaFieber, 1853 is considered as nomen dubium. Two novel species are described: Sphingonotus(Neosphingonotus)almerienseLlucia-Pomares sp. nov. and Sphingonotus (Neosphingonotus) nodulosusLlucia-Pomares sp. nov. from the southern part of the Iberian Peninsula. The new species are compared with other Iberian Sphingonotini and a key to the species is provided. (c) 2013 The Linnean Society of London » weiterlesen» einklappen
