Also some specimens from Burundi and Rwanda may refer to ater but need further studies (Portillo, Branch, Tilbury, Nagy, Hughes, Kusamba, Muninga, Aristote, Behangana & Greenbaum 2019).
Distribution: Congo-Kinshasa, Malawi, Tanzania, Zambia.

Some authors (e.g., Welch 1982; Wagner, Safari & Chenga 2014) have recognized leopoldi as a separate species, but without discussion. The taxon is known from only a single specimen from Rwanda. It is treated as a synonym of christyi herein, following Wallach, Williams & Boundy (2014).
