Naiabui, Hall Sound, New Guinea.
Previously placed in Megalurus. Traditionally treated as conspecific with C. timoriensis, but no apparent interbreeding where they meet in SC New Guinea. Large race alpinus might be a separate species. Extensive review of the entire complex required; present species often believed to comprise two groups, lowland (mayri, interscapularis) and montane (all of the other taxa), which possess different numbers of rectrices (10 and 12, respectively). Birds from alpine grasslands of Mt Hagen and Mt Wilhelm (in Central Highlands) described as race montanus, but considered to fall within range of variation of alpinus. Populations in C ranges of Snow Mts of uncertain racial affinity, tentatively included in nominate; those from Tolokiwa (W of New Britain) presumed to belong with interscapularis. Races mayri and wahgiensis have been included in nominate (and harterti might also belong there)#R, but note differences in number of tail feathers between mayri and nominate#R. Seven subspecies recognized.
