Comparative morphology and taxonomy of Sciacharis s. str., Chathamaenus Franz and Maorinus Franz (Coleoptera: Staphylinidae: Scydmaeninae)

摘要

Sciacharis s. str. is redefined based on the morphology of its type species, S. fulva Broun, and compared with sympatric genera Chathamaenus Franz (endemic to New Zealand) and Maorinus Franz (known from New Zealand and Australia). As a result, Chathamaenus is placed as a junior synonym of Sciacharis s. str., and Maorinus, originally described as a subgenus of Euconnus Thomson (under a preoccupied name Maoria Franz), subsequently elevated in rank, is here reduced to a subgenus of Sciacharis. Forty six new combinations resulted from this action are listed and Sciacharis (Maorinus) rakiuraensis nom. n. is proposed as a replacement name for Euconnus australis Franz, 1975, a junior primary homonym of Euconnus australis Franz, 1967.
