Aceroichthys gen. nov.

( Figs 1– 3 View Figure 1 View Figure 2 View Figure 3 , 38E View Figure 38 , 39 View Figure 39 )

Type species: Arius dioctes Kailola, 2000 .

Diagnosis

Posterior branches of mesethmoid very long, delimiting one-half of length of anterior cranial fontanel (8, 0> 2); lateral horn of lateral ethmoid variable length and laterally oriented (12, 1> 0); posterior branch of lateral ethmoid depressed (13, 0> 1); lateral expansions of orbitosphenoid and pterosphenoid absent (64, 1> 0); parasphenoid very wide in ventral view (66, 0> 1); exoccipital posterior process not supporting Müllerian ramus (94, 1> 0); premaxilla wide and short, its length more than four times in width (120, 1> 0); anteroventral portion of opercle subtrapezoidal, very long (127, 1> 0); no more than one-half of posterior part of interopercle contacting ventral margin of opercle (131, 1> 0); posterolateral processes of urohyal almost as long as distal portion of bone (162, 2> 0).

Etymology

Named after the Colombian ichthyologist Arturo Acero P. (b. 1954) to honour his valuable contributions to ariid taxonomy. Gender: masculine.

Included species

Aceroichthys dioctes Kailola, 2000 .

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

Remarks

Aceroichthys is established based on morphological and molecular evidence to accommodate Aceroichthys dioctes , with phylogenetic relationships first reported in a molecular study (Betancur-R. 2009).
