Description of the male of emPterorthochaetes/em emyunnanensis/em Ballerio, 2014 (Coleoptera: Scarabaeoidea: Hybosoridae: Ceratocanthinae).

The ceratocanthine genus Pterorthochaetes Gestro, 1898 (Coleoptera: Scarabaeoidea: Hybosoridae) includes about 26 valid species and occurs from the eastern Himalaya (Nepal and India) and southern China to northern Australia (Queensland) and Vanuatu Islands (Paulian 1978, 1987; Ballerio 1999, 2006, 2013, 2014).

Discovery of the genus Cycloxenus Arrow, 1925 (Coleoptera, Euxestidae) in mainland China, with the description of a new species.

The termitophilous genus Cycloxenus Arrow (Coleoptera, Euxestidae) is reported from mainland China for the first time. A new species, Cycloxenus guangxiensis sp. nov.

The p-type ATPase superfamily.

P-type ATPases function to provide homeostasis in higher eukaryotes, but they are essentially ubiquitous, being found in all domains of life. Thever and Saier [J Memb Biol 2009;229:115-130] recently reported analyses of eukaryotic P-type ATPases, dividing them into nine functionally characterized and 13 functionally uncharacterized (FUPA) families. In this report, we analyze P-type ATPases in all major prokaryotic phyla for which complete genome sequence data are available, and we compare the results with those for eukaryotic P-type ATPases.
