part of mentum ventromentum Fig 34,35,36,37,38,39,40,41,42,43,44 Abbr: Vm in ISBN:0-937548-00-6. In some mosquito and chironomid larvae, the lower and more proximal of the two transverse, usually projecting, specialized subdivisions produced when the mentum is completely (in mosquito larvae) or incompletely (in chironomid) divided by a transverse inflection of membrane; in anopheline larvae, developed as a well-sclerotized, apically dentate projection; in culicine larvae, hardly distinguishable from the adjacent membranes, but somewhat arbitrarily considered to be the narrow or broad, transverse apparently lightly sclerotized, spiculate area distal to the membrane regarded as the submentomental suture; probably not strictly homologous among all mosquito larvae and certainly not from mosquito larvae to chironomid larvae.
