Has in the past been considered conspecific with S. verreauxi, but is very distinct morphologically; race craddocki of that species has erroneously been listed for present species by some authors. Races distinctive, forming five groups: “nipalensis group”, “humii group”, “poliotis group”, “ripponi group” and “beaulieui group”; race crocotia here placed with humii group, but perhaps a semi-stable hybrid population. These groups treated as species by some authors#R and genetic evidence tends to support such an arrangement#R, but full presentation and evaluation of diagnostic (including vocal) characters lacking. Proposed race daflaensis (from Dafla Hills, in NE India) currently synonymized with poliotis, but specimens appear to show signs of intergradation towards latter, rather than being identical with it; further study required. Birds observed in NE Thailand (Phu Lang) and S Laos of uncertain racial identity; presumed to belong with, respectively, beaulieui and kamoli, but corroboration needed. Also, claimed sightings of race beaulieui at Ngoc Linh Kon Tum (within range of kamoli) merit investigation. Ten subspecies currently recognized.
