This species was first described by Robin Craw in 1987 using specimens collected on the slopes of Mount Tarndale in the Marlborough region in February by John S.

Upper- side forewing coloration and pattern dark brown with obscure wavy transverse lines.

[3]Craw goes on to distinguish this species from H. corcularia, H. semisignata, H. salmoni and H. ohauensis as a result of the differences of shape of both the male and female genitalia.
