Replacement of the illegitimate genus name Hungateiclostridium Zhang et al. 2018 in Hungateiclostridium mesophilum Rettenmaier et al. 2019 by Acetivibrio Patel et al. 1980, creating Acetivibrio mesophilus (Rettenmaier et al. 2019)

A recent publication has documented the fact that when the nomenclatural types of the genera Hungateiclostridium Zhang et al . 2018 [ Hungateiclostridium thermocellum (Viljoen et al . 1926) Zhang et al . 2018], Acetivibrio Patel et al . 1980 ( Acetivibrio cellulolyticus Patel et al . 1980) and Herbivorax Koeck et al . 2016 ( Herbivorax saccincola Koeck et al . 2016) are treated as being members of the same genus, i.e. Hungateiclostridium Zhang et al . 2018, Acetivibrio Patel et al . 1980 and Herbivorax Koeck et al . 2016 are treated as heterotypic synonyms, the name at the rank of genus to be used is Acetivibrio Patel et al . 1980 and Hungateiclostridium Zhang et al . 2018 is an illegitimate name. In a previous publication this led to the replacement of the genus name Hungateiclostridium Zhang et al . 2018 in the combinations Hungateiclostridium aldrichii (Yang et al . 1990) Zhang et al . 2018, Hungateiclostridium alkalicellulosi (Zhilina et al . 2006) Zhang et al . 2018, Hungateiclostridium clariflavum (Shiratori et al . 2009) Zhang et al . 2018, Hungateiclostridium straminisolvens (Kato et al . 2004) Zhang et al . 2018, Hungateiclostridium saccincola (Koeck et al . 2016) Zhang et al . 2018, Hungateiclostridium cellulolyticus (Patel et al . 1980) Zhang et al . 2018 and Hungateiclostridium thermocellum (Viljoen et al . 1926) Zhang et al . 2018. Given the fact that the name Hungateiclostridium Zhang et al . 2018 is illegitimate, Hungateiclostridium mesophilum Rettenmaier et al . 2019 must follow the same fate as other members of the genus and the illegitimate genus name replaced by the genus name Acetivibrio Patel et al . 1980, creating the combination Acetivibrio mesophilus (Rettenmaier et al . 2019).
