Abstract
The well-known Australian lycaenid butterfly, Candalides albosericea (Miskin, 1891), is a junior subjective synonym of Holochila caeruleolactea T.P. Lucas, 1891, which has not been used as a valid name after 1899. To protect the stability of the younger, but widely used name, the older and virtually unknown Holochila caeruleolactea (i.e., the senior subjective synonym) is suppressed under Article 23.9.2 of the Fourth Edition of the International Code of Zoological Nomenclature. By this action, Holochila albosericea Miskin, 1891 becomes a nomen protectum and Holochila caeruleolactea T.P. Lucas, 1891 a nomen oblitum. Lectotypes are designated for Holochila albosericea Miskin, 1891 and Holochila caeruleolactea T.P. Lucas, 1891, respectively.
