Its phyllodes are erect, narrowly elliptic to linear or narrowly oblong, mostly long, wide and thinly leathery with two to four parallel veins per millimetre. The flowers are cream-coloured to pale yellow and borne in spikes long. Flowering has been recorded in December and January and from May to July. The pods are pendulous, knife-like to linear, long, wide, more or less abruptly tapered at both ends, woody to blackish brown and glabrous. The seeds are narrowly oblong, long and dull black.
Taxonomy Acacia hyaloneura was first formally described in 1978 Leslie Pedley in the journal Austrobaileya from specimens collected from Pentland towards Torrens Creek in 1972.
Distribution and habitat This species of wattle is found in the western part of the top end of the Northern Territory and north-western parts of Queensland and along the Great Dividing Range from around Torrens Creek to about north of Clermont. It grows in Acacia or Eucalyptus woodland on slopes and ridges in sandy, clayey or rocky soils around and over sandstone or granite.
