Nomenclatorial fossicking - unearthing forgotten Selysian species names of Belgian Odonata

摘要

Five forgotten available species group names in Odonata, introduced by Edmond de Selys Longchamps in 1831, are listed and their taxonomic status is discussed. The following synonymies are presented: Agrio[n] cyaneus Selys, 1831 and Agrio[n] oeneus Selys, 1831 are junior subjective synonyms of Calopteryx virgo (Linnaeus, 1758); Agrio[n] cellaris Selys, 1831 and Agrio[n] virescens Selys, 1831 are junior subjective synonyms of Calopteryx splendens (Harris, 1780). Agrio[n] coralinus Selys, 1831, an obvious coenagrionid species, is ranked as a nomen dubium.
