Isthmus of Panama.
Formerly treated as one of many races of C. mellisugus (which see); an alternative was, on basis of bill colour, to split the complex into four species, of which present species was one, although this arrangement has at times been varied with the lumping of present species within the mellisugus group. A more radical evaluation of the complex#R is largely followed here but, owing to both the sheer number of taxa in the original complex and the diaspora of specimen material, comparisons between taxa and decisions on their taxonomic status are limited mainly to geographical neighbours. Thus, present form is specifically distinct from closest N member of the C. mellisugus complex, race salvini of C. canivetii, on account of much shorter, less forked tail (2); all-black (no red) bill (3); duller crown (2); and narrow zone of hybridization (2). It differs from melanorhynchus in Colombia in (scored from published data#R) plain vs highly iridescent crown (3); less grey in outer rectrices of female (1); much longer bill (2); shorter wing (1); longer tail (ns); heavier weight (ns). Monotypic.
