Taxonomy
This species was first described by George Hudson in 1908 using specimens collected by J. H. Lewis at Old Man Range, Central Otago, at an altitude of about 4,000 ft.[2] George Hudson described and illustrated this species in his book The butterflies and moths of New Zealand.[3] The syntype specimens are held at Te Papa.[4]
Description
Hudson described this species as follows:
The expansion of the wings is about 7⁄8 in. The forewings are dull bluish-grey, with two obscure slender yellowish-brown bands; there are three jagged blackish transverse lines, one at 1⁄4, one near the middle, and one at 3⁄4; there is a series of black and bluish-grey marks on the termen. The hindwings are yellowish-brown, clouded with dull-brown towards the base and termen, leaving the central portion paler. The cilia of all the wings is yellowish-brown mixed with black.[2]
Hudson pointed out that this species is very similar in appearance to Paranotoreas fulva. However D. simulans can be distinguished as its wings are broader, the transverse lines more indented, and the cilia not strongly barred.[3] The antennae of the male are unipectinated.[3]
