A review of Himalcercyon stat. nov., with description of a new species from the Chinese Himalaya and an updated key to Asian genera of Megasternini (Coleoptera, Hydrophilidae)
Himalcercyon Hebauer, 2002 stat. nov. is elevated to genus rank based on the unique form of its mesoventral elevation. The genus is reviewed, redescribed, and illustrated in detail. Two species are recognized: Himalcercyon mirus (Hebauer, 2002) comb. nov. from Nepal and H. franzi sp. nov. from Chinese Himalaya (Xizang Autonomous Region). Both species are illustrated and diagnosed. An updated key to the Asian genera of the tribe Megasternini (Coleoptera, Hydrophilidae, Sphaeridiinae) is provided, along with the SEM micrographs of ventral morphology of these genera. New replacement name Oreosternum nom. nov. is proposed for Oreocyon Hebauer, 2002 which is preoccupied by Oreocyon Marsh, 1872 (Mammalia, Oxyenidae) and Oreocyon Krumbiegel, 1949 (Mammalia, Canidae).
期刊介绍:
Founded in 1857 as Berliner Entomologische Zeitschrift, Deutsche Entomologische Zeitschrift is one of the World''s oldest international journals of systematic entomology. It publishes original research papers in English on the systematics, taxonomy, phylogeny, comparative morphology, and biogeography of insects. Other arthropods are also considered where of relevance to the biology of insects. The geographical scope of the journal is worldwide.
Deutsche Entomologische Zeitschrift (DEZ) is dedicated to provide an open access, high-quality forum to contribute to the documentation of insect species, their distribution, their properties, and their phylogenetic relationships. All submitted manuscripts are subject to peer-review by the leading specialists for the respective topic. The journal is published in open access high-resolution PDF, semantically enriched HTML and machine-readable XML versions.
