Sorry, no etymologies found.
Median lobe: of labium in Odonata, is the partly divided glossa or ligula; probably corresponds to united glossa and paraglossae (Butler).
Mentum: a labial sclerite bearing the movable parts; attached to and sometimes fused with the sub-mentum; corresponds to the (united) stipes of maxillae: in Coleoptera, what is usually called mentum is really submentum: in Diptera, the term is applied to the posterior oral margin: in Hymenoptera, is part of "tongue," the second joint bearing the labial palpi, paraglossae and ligula.
