Diagnosis: Geophagus diamantinensis is distinguished from all other species of the Geophagus brasiliensis species group by having the urohyal bone with a gentle anterior constriction (vs. strong constriction); presence of a small dark brow mark just posterior to pectoral fin (vs. absence); presence of a horizontal dark brown band on snout (vs. absence); and head more slender, head depth 77-86 % HL (vs. 87-122); G. diamantinensis is distinguished from G. itapicuruensis by having XIV spines on the dorsal-fin (vs. XIII), and from G. obscurus by having subterminal mouth (vs. terminal) (Ref. 118113).
