( Figs 1–3 , 9B , 11 )

Type species: Arius grandicassis Valenciennes, 1840 .

Diagnosis

Epiphyseal bar transversely elongate and longitudinally narrow (29, 0> 1); medial groove of cranium absent 30 (0> 1); vomer anterior margin very pronounced and acute (50, 0> 1); parasphenoid very wide in ventral view (66, 0> 1); posterior process of exoccipital absent (90, 1> 0); exoccipital bony crest parallel to vertebral column and mesially folded (92, 1> 2); sesamoid bone I irregularly shaped (145, 1> 2); accessory crest connecting transverse and median crests associated with neural spine of fourth vertebra present (204, 0> 1).

Ambiguous optimization: Lateral horn of lateral ethmoid acute (11, 1> 0); interior margin of otolith straight or slightly irregular (71, 0> 1); anterior opening of aortic canal at base of subvertebral process and anteroventrally oriented (77,?> 1); ventral tip of subvertebral process acute (80,?> 2); adipose-fin base long (222, 3> 1); gas bladder lateral diverticula present (243, 0> 1).

Remarks

The total-evidence analysis corroborates the monophyly, relationships, and species composition of Notarius as previously uncovered by molecular evidence (Betancur-R. et al. 2007; Betancur-R. 2009). The generic names Amphiarius and Aspistor , recognized as valid in previous morphological analyses ( Marceniuk and Menezes 2007, Marceniuk et al. 2012), are treated herein as junior synonyms of Notarius .
