The Genus Cheirogaleus: Unrecognized Biodiversity in Dwarf Lemurs

摘要: Two species of dwarf lemurs (Cheirogaleus) Madagascar are conventionally recognized. To investigate this taxonomy, I studied the samples in London and other collections. could distinguish 7 different morphs, differing by size features pelage, ears (hairy or naked), ear size, tail length, skull shape dentition. As multiple differentiate each form, they cannot be simply morphs within two conventional species: discrete genetic entities, hence distinct species. The Cheirogaleus medius group is split into closely related allopatric species, C. from western dry forests adipicaudatus southern spiny forest. major has widespread partially sympatric lowland rain crossleyi plateau margins. describe a previously known only type series, sibreei, new one with one, apparently to all others, central plateau. also discuss problems nomenclature, dating original description itself.
