The specific names Hemerobius elegans Stephens, 1836 (currently Sympherobius elegans), for a European brown lacewing (hemerobiidae) and Hemerobius elegans Guérin-Méneville, 1844 (currently Vieira elegans), for a Neotropical green lacewing (chrysopidae) are hereby conserved by ruling that Hemerobius elegans Guérin-Méneville, 1844 is not invalid by reason of being a junior primary homonym of Hemerobius elegans Stephens, 1836. Both names are in current use but are placed in different families and unlikely to ever be treated as congeneric in the future.
