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 .
