Auchenipterichthys
punctatus is most similar in appearance to A.longimanus,
which differs from A. punctatus primarily in lacking
distinct, dark spots covering the head or body. Auchenipterichthys
punctatus is readily distinguished from its other two congeners,
A. coracoideus and A. thoracatus, which have
coracoids that are covered ventrally only by a thin layer of integument
and appear to be exposed to the surface, the anterior teeth on
premaxilla are visible in the closed mouth and, typically, eight
(rarely nine) branched pelvic-fin rays (Ferraris et.al. 2005).
Remarks: At the northernmost collecting site
(altitude of about 150 m) along upper Rio Negro, the water was
blackish, over rocky bottoms. Stomach contents of four specimens
indicate a diet consisting mainly of insect nymphs and adults.
