The purposes of this application, under Articles 23.9.3 and 55.3.1 of the Code, are to conserve the current usage of (1) the family-group name Micruridae (Reptilia, Serpentes) for a family (sometimes treated as a subfamily) of New World coral snakes that frequently appear in literature pertaining not only to certain fields of herpetology but also to emergency medical care in Latin America; and (2) the nemertean family-group name Lineidae , by suppression of their senior homonym/ synonym Micruridae Ehrenberg, 1831 (Nemertea, Pilidiophora). The nemertean taxon Micrurinae was recognised as a subfamily of Lineidae until the early 20th century, but not since at least the 1970s. Afterwards, at the rank of family, Micruridae was used to refer to a differently constituted nemertean taxon in three ecological works published between 1998 and 2009.
