Range: —Greater Antilles and Guadeloupe; southern Mexico to Costa Rica ; Colombia to Suriname and Bolivia (BE, LP), Brazil . Ecology: —Uncommon; epiphytic in humid rain forests; 800–1800 m . Notes: —Occurring at lower elevations than all other Melpomene in Bolivia . Similar to M. moniliformis , but rhizomes are more compact and shorter (internodes 1 mm long or less vs . rhizomes distinctly prostrate, internodes 2–5 mm , rarely less in M. moniliformis and varieties). The scales of M. melanosticta may have small lateral lobes that bear apical glands like the main apex; they are very helpful for identification but not always present.

Ecology: —Uncommon; epiphytic in humid rain forests, cloud forests, and elfin forests; (1650) 2400–3250 m . Notes: —The dedication of this species was corrected in order to preserve the spelling of this name (Lehnert 2009). Most similar to M. pilosissima (M.Martens & Galeotti) A.R.Sm. & R.C.Moran ( var. pilosissima in southern Mexico to Costa Rica , Colombia , Venezuela ; var. tsatchelae (Labiak) Lehnert in Costa Rica , Colombia and eastern Venezuela to Peru ), which differs in having well developed hydathodes ( vs . inconspicuous or seemingly absent in M. michaelis ) and clearly clathrate scales ( vs . most cell lumina occluded).
