Taxonomy
The species was identified by Wise in 1958, based on a specimen collected from Kinloch on the northern shores of Lake Wakatipu in 1926 by C. E. Clarke.[4][5]
Description
Wise's original text (the type description) reads as follows:
ANTERIOR WING almost colourless, markings pale testaceous being two elongate transverse dots near base and two parallel transverse lines arising where Sc and R1 meet the costa and finishing at two-thirds where they join abruptly and continue as a single line almost to the dorsum just before the tornus. POSTERIOR WING almost colourless.
WING VENATION. Differs mainly from P. aureola (McLachlan) in the posterior wing where R2 and R3 arise separately, as in P. chiltoni
Tillyard, and from P. chiltoni in the anterior wing where apical fork 3 is fully formed, as in P. aureola. Length of anterior wing, 7–10 mm (0.28–0.39 in). Genitalia♂. Very close to P. aureola except that the spurs of the penis arise from its apex which is truncate and slightly bifid above. The spurs are moderately long, straight, and lie along each side of the penis..[4]
Wise noted that the species could be differentiated from other Pycnocentrodes due to the colour and pattern of its anterior wings.[4]
Specimens have an average forewing length of 8 mm (0.31 in) and hind wing length of 5.6 mm (0.22 in).[6]
