Gr. ερυθρος eruthros red; κερκος kerkos tail.
● Gadow 1884, W. Sclater 1930, and Cheke & Mann 2001, considered erythrocerca to be an original misprint for erythroceria. Despite von Heuglin’s 1864, correction, “in meinem Syst. Verz. d. V. N.-O.-Africa’s [1857] fälschlich erythrocerca geschreiben”, Rand in Peters’ 1967, wrote, “However, Heuglin’s nomen nudum for this taxon ...which predates Hartlaub’s name, is spelled “erythrocerca”; there seems no reason to believe Hartlaub did not also intend the spelling to be “erythrocerca”. Neither sex of the Red-chested Sunbird has a red tail, but common sense did not prevail and the species still holds this epithet! (Cinnyris).

holochlora / holochlorus
Gr. ὁλοχλωρος holokhlōros  all-green, all-yellow  < ὁλος holos  entire; χλωρος khlōros  green.
