Pollimyrus weyli
Pollimyrus weyli Dierickx, Lunkayilakio, Bills & Vreven, 2024

Family:  Mormyridae (Elephantfishes)
Max. size:  5.52 cm SL (male/unsexed)
Environment:  pelagic; freshwater; depth range 0 - 1 m
Distribution:  Africa: Mozambique.
Diagnosis:  Dorsal soft rays (total): 17-17; Anal soft rays: 21-23; Vertebrae: 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).
Biology:  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).
