Marcusenius kaninginii
From Kisekelwa et al. 2016:
Diagnosis. Marcusenius kaninginii belongs to the group of Marcusenius species with eight large circumpeduncular scales. Within this group it can be distinguished from M. dundoensis, M. fuscus and M. sanagaensis by its lower number of lateral line scales (43-47 vs. 49-61). It differs from M. ghesquierei and M. kutuensis by having fewer dorsal-fin rays (18-23 vs. 27-34) and from M. schilthuisiae by fewer anal-fin rays (27-30 vs. 32-35). It is distinguished from M. intermedius by a higher number of lateral line scales (43-47 vs. 38-43) and higher total vertebrae number (42-44 vs. 40-41). Furthermore, it can be distinguished from M. intermedius by the terminal mouth position and the rounded shape of the snout (vs. mouth sub-terminal and the snout pointed). It is distinguished from M. moorii by the blackish longitudinal band along the lateral line; the shallower body at the anterior base of the anal-fin depth (25.0-28.4 % SL vs. 28.1-33.5; Fig. 4a), the shorter pectoral fin (15.5-19.1 % SL vs. 17.7-22.8; Fig. 4b); and the deeper caudal peduncle (39-57 % of its length vs. 27-42; Fig. 4c).

From Kisekelwa et al. 2016:
Marcusenius kaninginii is found in the Lowa River basin near Walikale. The headwaters of the Lowa belong to the Albertine Highlands Ecoregion and extends downstream to the Up- per Congo ecoregion, as defined by Thieme et al. (2005). The former ecoregion includes the Kahuzi-Biega National Park (KBNP), which par- tially includes the Lowa basin (Brown & Abell, 2005). Some of the M. kaninginii specimens have been collected in the Luka, a left bank tributary of the middle Lowa River and in its tributary, the Elaimbi River. The Luka forms the main river of the Lowa basin draining the north-eastern part of the KBNP
