Delias carstenziana inexpecta Morinaka & Nakazawa, 1999

The presence of this species in close proximity to, but at lower altitude than, its sister species D. gilliardi ̡ is of interest. A single male was recorded by a local collector at Aiyamp creek, on the lower western slopes of the Mt Hagen massif. The holotype and other specimens were collected by Phil Saywer in July 1975 at ‘Poketamanda’ = Mt Nose, near Wabag, Enga Province, approximately 30km west of Mt Hagen.
