Etymology: Gymnocorymbus: Greek, gymnos = naked + Greek,korymb = summit, cluster of fruits and flowers (Ref. 45335); flaviolimai: Named for Dr. Flávio César Thadeo de Lima, for his contribution to the knowledge on the Neotropical ichthyology.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
South America: Rio Madeira of the Amazon basin in Bolivia, Brazil and Peru.

Morphology | Morphometrics
soft rays: 40 - 45;
Vertebrae: 32 - 34. Gymnocorymbus flaviolimai is distinguished from all congeners, except G. ternetzi, by its relatively smaller dentary and premaxillary teeth, with approximately one half the size of the length of those teeth. It can be separated from G. ternetzi by having premaxillary teeth with five cusps (vs. teeth with three cusps). It further differs from G. bondi and G. thayeri by the strongly convex distal margin of the anal fin (vs. straight in G. bondior slightly convex in G. thayeri), and by having i,6 pelvic-fin rays (vs. i,7) (Ref. 101636).
