Remarks.

Drawing in Ahl (1931b: 408, fig. 281).

First Lieutenant May collected between 1901 and 1903 in Luanda and surroundings, e.g. in Mubella near Funda on the Bengo River [Municipality of Cacuaco, Luanda Province, Angola] ( Matschie 1906). He donated the collected zoological objects as gifts to ZMB from 1902 to 1903 ( Anonymous 1903, 1904). Recently, the type was erroneously mentioned as probably lost by Marques et al. (2018).
