Host associations of Melanterius Erichson (Coleoptera: Curculionidae: Cleogonini), with a diagnosis and delimitation of the genus and description of five new species Author Pinzón-Navarro, Sara V. Author Jennings, Debbie Author Oberprieler, Rolf G. text Zootaxa 2017 4298 1 1 77 journal article 32536 10.11646/zootaxa.4298.1.1 e2c6a7ae-f2f7-45cb-a9c0-e885dd74927c 1175-5326 840354 6F38752A-0669-488E-879B-8881EC80ECF2 The M. laticornis group This tentative group includes species that have the dorsal vestiture comprising only minute and very sparse setae, the procoxae contiguous (not separated by a distinct septum) and the mesoventrite usually anteriorly raised into a transverse bar with raised corners, on which the tip of the rostrum rests in repose. A similar condition, however, also occurs in some species of the M. maculatus group. The M. laticornis group encompasses species such as M. atronitens Lea, 1931 , M. compositus Lea, 1909 , M. corosus Boisduval, 1835 , M . laticornis Lea, 1913 , M . mediocris Lea, 1913 , M. persimilis Lea, 1909 , M. porosus Lea, 1899 , M. strabonus Lea, 1899 and M. vulgivagus Lea, 1899 . Hosts are known only for M. corosus .
