Moltena Evans, 1937

Evans (1937) introduced this genus for the single species Moltena, which he considered to resemble Ploetzia apart from having a normal proboscis, rather than a vestigial one as in Ploetzia . In his review of the genus Chondrolepis, De Jong (1986) found that based on an analysis of adult characters Chondrolepis seems to form a monophyletic group with Ploetzia and Moltena, with Zophopetes as their nearest relative. We have treated the early stages of the grass-feeding Chondrolepis in Cock & Congdon (2014), and the palm-feeders Ploetzia and Zophopetes in Cock et al. (2014), but deferred a comparison of the three genera until we had treated Moltena .
