A. O. Hume, 1875,
Pakchan estuary, Tenasserim, south Myanmar.
Closely related to P. papillosa, with which often considered conspecific. Differs from latter, however, in having no papillose red mid-crown to hindneck (3) but possessing instead a bluish-white band of bare skin from hindneck and nape forward around throat (3)#R; it is also larger (effect size for bill of male 2.89; score 2). Monotypic.
Once widespread from Myanmar to SW China and S to Indochina and Borneo, range now much reduced; small remaining population now focused on N Cambodia, with tiny additional numbers in adjacent S Laos and, disjunctly, in S Borneo (mainly along R Mahakam)#R.
