Hypoptopoma inexspectatum (Holmberg, 1893)
Description
Vertebrae: 25. This species is distinguished from its congeners by having the odontodes on the snout margin, the rostral plate, and first and second infraorbitals arranged in regular series; along the rostral margin, the dorsal and ventral series are separated by an odontode-free discontinuity approximately as wide as the base of individual odontodes; along the first and second infraorbitals, the discontinuity becomes narrower, but forms a dividing line between ventral and dorsal odontode series; odontode arrangement becomes more irregular posterolateral to the second infraorbital, and individual odontodes become roughly oriented with the trunk axis; in all other congeners, the ventral and dorsal odontodes on the rostrum are variably separated and/or covered by soft tissue, and odontodes are typically not clearly aligned in series (Ref. 84367).
