The Australian species of the
Ariidae family have been revised and placed in a new
genus, Neoarius. "Neo" meaning
new in Latin. Description: Dorsal
spines (total): 1; Dorsal soft rays (total): 7; Anal
spines: 0; Anal soft rays: 16 - 19. The species of
Neoarius can be differentiated from all other
genera of Ariidae by the combination of two shared
characters: (1) lateral face of third pharyngobranchial
conspicuous and acute (shared with Arius,
Brustiarius, Nedystoma, Netuma,
Plicofollis and Potamosilurus);
(2) anterior process of first pharyngobranchial on
the central part of this bone (shared with Netuma).
Habitat: Occurs in rivers and smaller streams,
frequently in slow-flowing, turbid conditions, and
also in lakes and lagoons. Sometimes found in brackish
estuaries. Diet: Feeds on aquatic
plants, benthic crustaceans, insect larvae, bottom
detritus and also fishes.
Northern Australia, inhabits coastal rivers and streams
in the Gulf of Carpentaria and northern areas of the
Northern Territory as far west as the Mary River system,
and New Guinea. Type locality: Pools
of Flinders River, near Hughender and Richmond, Queensland,
Froese, R. and D. Pauly.
