The western longnose spurdog, "Squalus sp. E", is a dogfish which is yet to be formally described. It is a member of the family Squalidae, found on the continental shelf off the northwest and southwest coasts of Western Australia, at depths of between 300 and 510 m. Its length is at least 55 cm.

The western longnose is a rare, small and slender dogfish with a narrow head and long narrow snout. There is a short medial barbel on the anterior nasal flaps. The pectoral fin has a shallowly concave posterior margin. The first dorsal fin is moderately high with a short spine.

Coloration is light grey above, paler below, with no white spots. The pale dorsal fins have dusky tips and posterior margins. There is a dark blotch on part of the caudal fin's posterior margin.

Its reproduction is ovoviviparous.
