The purpose of this application, under Articles 11, 23, 31 and 32 of the Code, is to confirm the availability of and to maintain the usage of the name Galago demidoffFischer, 1806 for Demidoff's Dwarf Galago from western and central Africa and its priority over the objective junior synonym Macropus (Galago) demidoviiFischer, 1808, and to suppress subsequent incorrect spellings, under Articles 19 and 33 of the Code. The original specimen of Galago demidoffFischer, 1806 has been destroyed so a further purpose of this application is to designate a neotype, under Article 75.3 of the Code. A name of dubious identity, Lemur minutusCuvier, 1797, has been confused with that of Galago demidoff and Galago senegalensisGeoffroy, 1796. This name has had no valid usage for well over a century and is here regarded as a nomen oblitum, under Article 23 of the Code. In order to clarify taxonomic status, it is also proposed to designate a neotype for Lemur minutusCuvier, 1797, under Article 75.3 of the Code. It is proposed that G. demidoff should be maintained as the prior name for the taxon and that all subsequent incorrect spellings of the name be suppressed.
