Dendrocopus [sic] sordidus
Hitherto treated as conspecific with H. concretus, but differs in having red crown with grey crest vs entire crown and crest red, with darker, less fiery colour and more glossy texture (3); proportion of buff-white to black in wings much greater (2); greyish-olive vs sooty-grey face, neck and underparts (1); slightly shorter wings and tail (effect size for wing length −2.13; score 2). Sumatra and Borneo populations named as race coccometopus, but regarded as insufficiently different to warrant separation. Monotypic.
