( Figs 1–3 , 24 )

Diagnosis (all of ambiguous optimization)

Posterior cranial fontanel formed by frontals and parieto-supraoccipital (25, 1> 0), state 1 in Arius leptonotacanthus , Arius nenga , Osteogeneiosus , and Pseudosciades ; anterior margin of otolith straight or slightly irregular (71, 0> 1), state 0 in Hemiarius stormii ; otolith posterior margin rounded (74, 1> 0), state 0 in Hemiarius stormii ; orientation of exoccipital bony crest perpendicular to vertebral column and directed posteriorly (92, 0> 1), state 0 in Hexanematichthys ; sesamoid bone I very long and subtriangular (145, 0> 1), state 2 in Osteogeneiosus ; 14 or fewer ribs (213, 1> 0), state 1 in Hexanematichthys ; second dorsal cleithral process dorsally directed and parallel to first dorsal process (226, 0> 1), state 0 in Arius aff. nenga , Batrachocephalus , and Hexanematichthys .

Remarks

The recognition of the subtribe Ariina corroborates the results of a previous molecular study (Betancur-R. 2009), which uncovered a distinct lineage of the Ariinae in Asia vs. that in Papua New Guinea and Australia ( Doiichthyina ).
