Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 0; Mjukstrålar i ryggfenan (totalt): 19-21; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 25 - 27. A moderate-sized Paramormyrops (Ref. 81635). The head profile is slightly concave dorsally; snout is U-shaped from above, it is truncate, rather deep, and fleshy (Ref. 81635). The fleshy chin appendage is slightly enlarged (Ref. 81635). The colour is dark chocolate-brown overall, including the fin rays (Ref. 81635).
