binomial_authority = The eastern longnose spurdog, "Squalus sp. F", is a dogfish which is yet to be formally described. It is a member of the family Squalidae, found on the continental shelf off northern Queensland, at depths of between 220 and 500 m. Its length is up to 64 cm.

The eastern longnose spurdog is very similar to the western longnose spurdog, "Squalus sp. E", but has a shorter snout, longer first dorsal fin spine, lower first dorsal fin, and larger caudal fin. The pectoral fin has a straight posterior margin.

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.
