This species was first described by George Howes in 1911 using specimens collected at Mr O'Connors house at Titahi Bay, Porirua and given the name Eucymatoge arenosus. George Vernon Hudson discussed and illustrated this species in his 1928 publication. Hudson changed its epithet to arenosa. In 1988 John S.

A series of minute black marks along veins and around termen.
