Comments. Seifert (2019b) showed that the type series represent F 1 hybrids of L. emarginatus X platythorax . According to article 23.8 of ICZN, a species-group name established for an ”animal“ later found to be a hybrid must not be used as the valid name for either of the parental species, even if it is older than all other available names for them. Furthermore, article 1.3.3 excludes a name from the provisions of the code if proposed for ”hybrid specimens as such“.
