Remarks. The description was communicated 6 December 1892 but the Proceedings were published in April 1893. The correct year of authority is accordingly 1893 not 1892 as given by Wilson and Reeder ( 2005). Collett ( 1893) noted “ 7 specimens procured; University Museum, Christiania”. Only the five listed specimens were located. All specimens are labeled “ Type ”.
