Etymology: Pollimyrus: Because of Dr. Max Poll, ichthyologist + Greek, myros, -ou = the male of the morey eel; weyli: Named after the late Professor Dr. Olaf L.F. Weyl (1972–†2020) (SAIAB) for his contributions to African ichthyology and his work in the Buzi River system within the framework of his PhD, expanding the collections housed at SAIAB and increasing the understanding of the biodiversity in the region.
Eponymy: Dr Max Fernand Leon Poll (1908–1991) was a Belgian ichthyologist, and ‘connoisseur of the fish fauna’. [...] (Ref. 128868), visit book page.

पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 17; ऐनल सौफट रेज़: 21 - 23; जानवरों की रीड़ का जोड़: 38 - 39. This species is distinguished by the following characters: upper jaw wide, 22.6%-24.5% HL; caudal peduncle thick, 23.4%-23.8% BD; dorsal, anal and pectoral fins rounded; chin small; body deep, 29.6%-29.9% SL; head wide, 55.2%-58.7% HL; anal fin short, 20.2%-22.5% SL; pectoral fin short, 18.1%-19.6% SL; D 17 (Ref. 138541).
Body shape (shape guide): short and / or deep; Cross section: compressed.
The holotype was caught in a weed-filled non-flowing stream close to the main channel of the Buzi River, some 154 m a.s.l. The vegetation consisted mostly of a fine leafed Potamogeton (like Potamogeton pusillus) and a few water lilies (Nymphaea). Vegetation cover was close to 100%, where the specimen was caught by raking with a big hard-framed hand-net through the weeds. Water depth was less than 1 m with a mixed substrate of sand and rocks. The paratype, on the other hand, was caught in a lower-altitude tributary, at 138 m a.s.l., with a good flow, and completely covered over by emergent Phragmites; there was no submerged aquatic vegetation. It was collected by electrofishing with a Samus backpack at less than 1 m depth with a substrate of cobbles and banks undercut with a lot of rootstocks (Ref. 138541).
