Mormyridae (Elephantfishes)
Etymology: Pollimyrus: Because of Dr. Max Poll, ichthyologist + Greek, myros, -ou = the male of the morey eel; krameri: Named after Professor Dr. Bernd Kramer (1943–) (University of Regensburg, Germany) for his contributions to ichthyology and study of weakly electric fish, southern African Mormyridae in particular.
Eponymy: Dr Max Fernand Leon Poll (1908–1991) was a Belgian ichthyologist, and ‘connoisseur of the fish fauna’. [...] (Ref. 128868), visit book page.

背鰭 (合計) : 15; 臀鰭: 21 - 24; 脊つい: 37 - 38. This species is distinguished by the following characters: caudal peduncle thick, 23.4%-23.4% BD; pectoral fins rounded; dorsal and anal fins’ anterior part rounded (similar height of rays); chin small; body shallow, 25.3%-26.7% SL; snout short, 13.5% HL; shorter snout–posterior side eye distance, 39.4%-39.7% HL; eye small, 14.3%-15.5% HL; posterodorsal distance short, 36.8%-37.0% SL; head long. 24.8%-25.2% SL; D 15; circumpeduncular scales 13-14 (Ref. 138541).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Collected from a stream that has dense marginal vegetation. The bottom of the river is sandy and rocky, without aquatic weed beds. Marginal Phragmites reeds, grasses, sand trees result in significant marginal root stocks along some river edges. The small Nkupo Stream was not flowing and did not have aquatic macrophytes, but it was filled with filamentous algae and emergent plant root stocks. During the wet season, this stream would be part of the main river. The specimens were collected using seine netting into and underneath root stocks.
