Further study on the phylogeny,taxonomy and distribution of the genus Veturius Kaup in Central and South America (Coleoptera: Passalidae)

This study provides data on the phylogeny, taxonomy and distribution of 14 known and five new species of the Neotropical genus Veturius Kaup (Proculini), belonging to various subgenera and species groups: V. (Veturius) latissimus n. sp. (Colombia, Central Andes) and V. (V.) calimanus n. sp. (Pacific slope of the Occidental Cordillera) are separated from V. (V.) caquetaensis Boucher, 1988, which seems restricted to the Amazonian slope of the Oriental Cordillera (Caquetá, Putumayo); V. (V.) sinuatomarginatus Luederwaldt, 1941 (Costa Rica), n. syn. of V. sinuatocollis Kuwert, 1890; V. sinuatocollis aculeatus Luederwaldt, 1941 (syntype from Costa Rica); V. (V.) aspina Kuwert, 1898 (located in Occidente of Ecuador, Guayaquil); V. (V.) yahua Boucher, 2006 (located in Occidente of Ecuador, Pichincha and SW Colombia, Nariño); V. (V.) guntheri Kuwert, 1898 (located in Peru, SE Puno and Colombia, W Putumayo); V. (V.) cephalotes (Le Peletier & Serville, 1825) (citation from Guyana); V. (V.) sinuatus (Eschscholtz, 1829) (previous synonymy); V. (V.) libericornis Kuwert, 1891 (located in Peru, Cuzco); V. (V.) lepidus Fonseca, 1999 (revision; located in Colombia, Amazonas, Putumayo and Peru, Loreto); V. (V.) transversus (Dalman, 1817) syntype; previous synonymy of V. trituberculatus (Eschscholtz, 1829) with V. assimilis (Weber, 1801) and located in Brazil, Mato Grosso]; V. (V.) sinuosus (Drapiez, 1820) (corrected reference for Colombia); V. (Publius) crassus (Smith, 1852) (new syntype); V. (P.) danieli Boucher, 2006 (holotype deposit); V. (P.) vazdemelloi Boucher, n. sp. (Andes of Ecuador, Azuay); V. (Ouayana) unicornis Gravely, 1918 (located in Colombia, E Vaupés); V. (O.) costaianus Boucher, n. sp. (Venezuela, Amazonas, NW Pacaraima Massif); Ticoisthmus Boucher, n. subg., for the species group of V. (O.) laevior (Kaup, 1868), of southern Central America; and V. (T.) brachypterus Boucher, n. sp. (Costa Rica, Sierra Talamanca). Ticoisthmus is considered the sister group of Ouayana. It belongs to the Meso-American low mountain dispersion pattern and demonstrates, especially in the genus Veturius, but also more generally in the Neotropical passalids, the hot-spot characteristics, with diversity and endemism, of the narrow land between the Depression of Nicaragua and the Isthmus of Panama.
