The purpose of this application, under Articles 23.2 and 23.9.3 of the Code, is to conserve the usage of the genus-group name\ Cognettia\ Nielsen \& Christensen, 1959\ (Enchytraeidae, Oligochaeta, Annelida) for a genus of annelid worms (type species\ Pachydrilus sphagnetorum\ Vejdovsk{\'y}, 1878\ ({\textquoteleft}1877{\textquoteright})).\ Cognettia,\ a name for a Holarctic genus of terrestrial and semi-aquatic annelid worms, is threatened by two subjective senior synonyms,\ Euenchytraeus\ Bretscher, 1906\ and\ Chamaedrilus\ Friend, 1913. If these two names are considered synonyms,\ Euenchytraeus\ will replace\ Cognettia; if they are considered to represent two different genera,\ Chamaedrilus\ will replace\ Cognettia.\ In 2015 Martinsson et al. adopted the latter course, replacing\ Cognettia\ by\ Chamaedrilus,\ and allocated its species between both\ Euenchytraeus\ and\ Chamaedrilus. Cognettia\ is a widely used name and is well-known in the fields of soil biology, ecology, and ecotoxicology, and we propose it be given precedence over\ Chamaedrilus\ and\ Euenchytraeus,\ which had not been used as valid for almost a century.
