Subtribe Doiichthyina Weber, 1913

MP 68, BI 1, ML 50

( Figs 1–3 , 38 )

Type genus: Doiichthys Weber, 1913 .

Diagnosis

Accessory tooth plates small, transversely elongate and narrow (60, 2> 0), state 3 in Doiichthys . Ambiguous optimization: Mesethmoid medial notch large and shallow (1, 1> 0), reversed Brustiarius (except Brustiarius utarus ), Cinetodus , Neoarius , Pachyula , Pararius mastersi , and Potamosilurus velutinus ; posterior cranial fontanel formed by frontals and parieto-supraoccipital (25, 1> 0).

Remarks

The recognition of the subtribe Doiichthyina corroborates the results of a previous molecular study (Betancur-R. 2009), which recognized two distinct lineages of Ariina , one in Papua New Guinea and Australia ( Doiichthyina ) and the other in Asia ( Ariina ).
