Distribution ( Fig. 49 ). Collessiama damani has been collected in rainforest and sclerophyll eucalypt forests east of the Great Dividing Range in south-eastern Queensland and north-eastern New South Wales. The specimens collected from Burleigh Heads in the 1950’s may indicate the presence of coastal rainforests that have been overcome by development since their collection.

Etymology. Collessiama damani is named for Damian ‘Da Man’ White who helped Narelle Power collect many of the specimens ( Power, 1998).

Comments. Collessiama damani is easily distinguished from Collessiama narelleae by the diagnostic characters, especially the lack of the medial orange infuscation on the wings.
