5. Holopyga amoenula Dahlbom, 1845

Holopyga amoenula Dahlbom 1845: 4 . Lectotype ♂ (designated by Rosa in prep.); Greece: Rhodes Isl. (NRM) (examined) ( Holopyga lucida group).

Remarks. Dahlbom (1954: 53) considered H. amoenula to be a variety (var. d) of the newly described species H. ovata (= H. generosa Förster), with no regard to the principle of priority, not yet applied at that time. Later Mocsáry (1889: 127) treated H. ovata as a junior synonym of H. amoenula and several authors erroneously followed his interpretation. From the Nordic and Baltic countries amoenula was reported either as a distinct species (Bischoff 1910: 440, Sahlberg 1910: 98 (as Elampus amoenus), Aurivillius 1911: 7, Tumšs 1976: 22) or as a variation of Holopyga gloriosa (Jansson 1922: 33, Jansson 1934: 287, Hellén 1935: 8, Fahlander 1954: 254). The name gloriosa has been suppressed by the Commission on the Iczn (ICZN 1998). Only after Linsenmaier's revision of the European species (1959), H. amoenula was correctly identified and recognized as a separated and valid taxon endemic to Rhodes Island.
