Treatment

Neoarius Castelnau, 1878 View in CoL View at ENA

BI 0.74

( Figs 1–2 View Figure 1 View Figure 2 , 48 View Figure 48 )

Type species: Arius curtisii Castelnau, 1878 .

Diagnosis

Mesethmoid median portion moderately wide (2, 2> 1); pterotic mesial border with parieto-supraoccipital longer than anterior border with sphenotic (36, 0> 1); anterior process of first hypobranchial in middle of bone (174, 0> 1).

Ambiguous optimization: Lateral horn of lateral ethmoid compressed and spatulate (11, 0> 1); one-half or less of interopercle posterior part contacting ventral margin of opercle (131, 1> 0); Müllerian ramus distal one-third markedly curved (208, 1> 2).

Included species

Neoarius berneyi Whitley, 1941

Neoarius graeffei Kner & Steindachner, 1867

Neoarius aff. graeffei sp 1

Neoarius aff. graeffei sp 2

Neoarius hainesi Kailola, 2000

Neoarius midgleyi Kailola & Pierce, 1988

Neoarius pectoralis Kailola, 2000 * sedis mutabilis.

Habitat and distribution: Fresh, brackish, and marine waters, southern New Guinea and Australia ( Fig. 38 View Figure 38 ).

Remarks

The MP and BI analyses support the monophyly of Neoarius in contrast to previous morphological studies, which treated the group as asynonymof Ariopsis ( Kailola2004) orasavalidgenus ( Marceniuk and Menezes 2007, Marceniuk et al. 2012). This study supports the inclusion of Neoarius midgleyi and two currently unnamed species into the genus (Betancur-R. 2009) and renders Amissidens (type species: Arius hainesi Kailola, 2000 ) into synonymy.
