Taxonomic Revision and Phylogeny of the Genus Peltocercyon d'Orchymont, 1925 (Coleoptera: Hydrophilidae: Megasternini)

Original language description

The Asian-endemic genus Peltocercyon d&apos;Orchymont, 1925 is revised and redefined based on morphological characters and DNA data. The metaventrite, with complete femoral lines crossing the arcuate ridges, is confirmed as the best diagnostic characterfor Peltocercyon in contrast to the morphology of the prosternum and mesoventrite which vary within the genus. DNA data reveal that Peltocercyon contains two separate lineages and that aedeagal morphology is more phylogenetically informative than external characters. A total of 17 species are recognized, of which nine are newly described: Peltocercyon basirugosus sp. nov. (China; Laos), P. carnarius sp. nov. (Indonesia; Philippines; Malaysia), P. kouwenkaii sp. nov. (China), P. latifossus sp. nov. (Indonesia), P. maculipennis sp. nov. (China; Laos; Vietnam; India), P. medogensis sp. nov. (China), P. rugosipennis sp. nov. (China), P. splendidus sp. nov. (China; India), P. taylorae sp. nov. (China; Laos; India). Three species are transferred to Peltocercyon from Cercyon Leach, 1817: Peltocercyon vagus (Sharp, 1884), comb. nov., P. vividus (d&apos;Orchymont, 1925), comb. nov., and P. sanaii (Hoshina, 2008), comb. nov. Peltocercyon coomani d&apos;Orchymont, 1925 is newly recorded from China, Laos, Thailand and Malaysia, P. lunulatus (Gemminger &amp; Harold, 1868) from China, Laos, Malaysia, Cambodia and Myanmar, and P. vividus for Malaysia, Thailand and Indonesia. Diagnostic characters of all species and species groups are illustrated by photographs and SEM micrographs and an identification key and distribution maps of all species are provided. All known Peltocercyon inhabit decaying organic material; we provide the first hypothesis on the evolution of their habitat preferences.
