Ordo: Siluriformes
Familia: Trichomycteridae
Name
Trichomycterus sp. B – Wikispecies link – Pensoft Profile
Distribution
Upper rio Paraúna, rio São Francisco basin, and upper rio Santo Antônio, rio Doce basin.
Diagnosis
Trichomycterus sp. B differs from its congeners of the study area by having nine branchiostegal rays; high concentration of rounded dark spots on the head and sides of the trunk, dorsum, and belly, which may fuse and form small vermiculations; rounded caudal fin.
Remarks
In this study, we refer Trichomycterus sp. B such as a putative new species from the rio Doce basin, due to differences in morphology and color pattern between this species and another with similar color pattern from Southeastern Brazil river basins such as T. brasiliensis group, T. argos, T. landinga, T. novalimensis, and T. rubiginosus.
