(syn. Melidectes Ϯ Sooty Honeyeater M. fuscus) Portmanteau of genus Melidectes P. Sclater, 1873, honeyeater, and Gr. ονυξ onux, ονυχος onukhos nail (i.e. serrated bill); "MELIONYX gen. nov. Type, fuscus De Vis 1897 (Anthochoera). ... Associated with Melidectes are three other blackish birds which have little or no bare eye space, and neither gape nor throat wattles. The first to be named was described as having a small bare spot below and behind the eye only. The second very similar, while the third scarcely shows any bare skin. They all agree in their dark brown to blackish coloration, and in the presence of a more or less developed "beard." That is the chin and upper throat show long whitish straggling feathers, with the tips bare. The Sooty Honey-Sucker is selected as the type of this series, which is characterized by its slender form with slender bill and lengthened tail, the long wedge-formed tail being much longer than the wing while the slender bill is well over an inch in length. This series may be named Melionyx, and can be regarded as a genus, or subgenus, as long as it is available to designate the distinction and indicate the diverse development. The second species agrees in general, Nouhuys' Honey-Sucker, but has the beard much better developed, while the third, Gilliard's Honey-Sucker, has in addition produced a very lengthened bill with the anterior edges of the mandible very finely regularly serrate. The beard is still more notable." (Iredale 1956).
