Distinguished from known Bryconamericus species by: the insertion of the first three pterygiophores in front of the anal fin on the first caudal vertebra of the spine; a short ischium process; the dentition of eight small teeth; and the rhinosphenoid is wide in its posterior extreme where it makes contact with the cartilage (Ref. 49955).
與已知 Bryconamericus 種區分了被: 在棘的第一個尾部的脊椎骨上的臀鰭前面中的第一個的嵌入三個支鰭骨; 一個短的座骨突起; 八個小的齒的生齒; 而且 rhinosphenoid 是廣泛的在中它的在後部極端在那裡它製造與軟骨組織的接觸.(參考文獻 49955)
