Crephelochares abnormalis, is a species of water scavenger beetle found in Cambodia, Sri Lanka, Taiwan, Thailand, Vietnam, Ryukyu Islands and Indonesia: Borneo, Java, Sulawesi, Sumatra. [1] [2] [3] [4] [5]

Taxonomy

The species was originally described by David Sharp in 1890 under the genus Philydrus. [6]

It was transferred to the genus Chasmogenus when Chasmogenus was considered a subgenus of the genus Helochares and a synonym of Crephelochares . Additional details about the taxonomic history of Chasmogenus and Crephelochares can be found in Girón and Short (2021). [7]

Description

The species is closely related to Chasmogenus orbus , only can be separated by features of the aedeagus: parameres without or with small subapical tooth, where the apex is broadened inwards. Median lobe gradually becomes narrow from apical quarter to apex and widely truncate apically. [8]
