Taxonomy of 'Euconnus complex'. Part III. Morphology of Euconnus subgenus Napochus and revision of the Australian species (Coleoptera, Staphylinidae, Scydmaeninae)

Morphological structures of the type species of Euconnus (Napochus) are described and illustrated, and compared with those of Euconnus s. str. Napochus is maintained as a subgenus of Euconnus, and its revised diagnosis is given. Australian species of Napochus are revised: E. palmwoodianus Franz and E. pisoniae Franz are redescribed, and E. setiphallus sp. n., E. yadhaigana sp. n., E. microlaminatus sp. n, E. feeneyi sp. n. (with a subspecies E. feeneyi parallelilaminatus ssp. n.) are described. An unusual variability in body size and proportions of body parts found in E. feeneyi is analyzed and discussed.
