title: The correct name of the type species of the genus Methanocorpusculum. Request for an Opinion.
abstract: We propose that Methanocorpusculum parvum with type strain XII must remain the nomenclatural type of the genus Methanocorpusculum, in spite of the fact that the description of Methanogenium aggregans with type strain MSt, later transferred to the genus Methanocorpusculum as comb. nov. and then proposed as a heterotypic synonym of Methanocorpusculum parvum, was published before Methanocorpusculum parvum strain XII.
