Notes         :
Delias catocausta is described by Jordan, 1911, from Mount Goliath. Roepke (1955) described D.c.nigerrima from the Andraea River, 60Km West of Mt. Goliath, at the same time saying that it is " a weak subspecies". More recent specimens lead scientists to consider D.c.nigerrima to be only a synonym of D.c.catocausta.

In 1990, Mastrigt described
D.c.eefi from Tembagapura, on the southern slopes of Carstensz Peak. Tuzon, in 1995, raised this to specific species level. However, until detailed genetic studies have been made, I will agree with Mastrigt, and retain it on a subspecific level. At the same time, I would not be at all surprised should any further investigation reveal D.c.eefi to be a different species.
