dehanna Pagenstecher comb. n.
Arctia dehanna Pagenstecher, 1885, Jb. nassau Ver. Naturk.
Niasana dehanna Pagenstecher; Roepke, 1937 (see below);
Holloway, 1976: 4.
Diagnosis. The forewings are medium brownish grey with distinctive costal and
dorsal patches medially in pink and yellow. The hindwings are similar with a
complete medial band and a basal pinkish zone. The body and extreme base of the
forewings are also deep pink.
Taxonomic notes. Roepke (1937, Ent. Z. Frankfurt a. M. 51: 195) described the
genus Niasana and three subspecies of dehanna: javana, borneana and
ruberrima (Simalur). The species is somewhat variable and the validity of
these subspecies is questionable.
Geographical range. Sundaland.
Habitat preference. T. dehanna is infrequent in rain forest habitats from the
lowlands to 1500m, perhaps favouring lowland forest.
