" Geophagus taeniopareius and G. grammepareius, new species, are distinguished from congenerics by their relatively small size, naked or almost naked dorsal fin and a prominent dark stripe from the eye to the comer of the preopercle in both adults and young. Geophagus taeniopareius occurs in rivers draining the western Guiana Shield and in the lower Rio Caura. lt reaches 143 mm SL and is distinguished from G. grammepareius by having minute scales along the dorsal fin base, higher scale, vertebral and dorsal fin counts, microbranchiospines and different colour pattern. Geophagus grammepareius reaches 103 mrn SL and occurs in the upper Rio Caura and lower Rio CaronĂ­. It is distinguished from G. taeniopareius by low meristics, wide lips, lack of microbranchiospines and different colour pattern "
