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.
