Forms part of assemblage often referred to as subgenus Cookilaria. Often treated as conspecific with P. leucoptera, but differs in slightly paler and less extensive hood (1); broader dark trailing edge of wing (1); lack of paler inner webs of primaries (1); shorter legs (from published figures#R, effect size 2.3; score 2); longer wing (from published figures#R, effect size 2.4; score 2). Newly described form magnificens#R (Banks Is) requires further assessment#R. Provisionally treated as monotypic.
