Genus Portmacquaria Blome, 2005

The monospecific genus Portmacquaria was described by Blome (2002) under the name Macquaria from a sandy beach of eastern Australia. Later it was renamed into Portmacquaria by Blome (2005) to avoid homonymy with a fish genus. Portmacquaria is characterized by a unique combination of Euchromadorinae characters: the dorsal tooth is obviously solid in its basal part and in the dorsal shoulder, and there are flanges on the lateral walls of oesophastome as well as ventral onchia. The cuticle in the anterior part of the pharynx is more thickened and has a conspicuous posterior bulb.

Diagnosis (modified from Blome 2002): Cuticle complex with lateral differentiation formed by two longitudinal rows of enlarged dots joined by transversal bars. Anterior sensilla in three separate circles, whereas the sensilla of the first circle are papilliform and the four setae of the third circle are longer than the ones of the second circle. Amphideal fovea as a transverse slit without market thickening of the margins. Solid dorsal tooth opposed by two small ventrosublateral teeth, all with flanges forming a cylindrical posterior part of buccal cavity. Pharynx with well-developed posterior bulb. Spicules weakly cuticularised and arcuated. Gubernaculum of irregular shape, and lateral pieces of indistinctly L-shaped form. Ventrally pre- and postvulvar cuticular thickenings in females. Tail conical with three indistinct caudal glands.

Number of valid species: 1.
