On three unpublished lectotype designations and on the status and positions of Kreizbergius simo-group taxa (Lepidoptera, Papilionidae)
The taxonomic status and positions of taxa described within the genus Kreizbergius Korshunov, 1990 (the simo-group sensu Ackery, 1975) are rearranged. Lectotypes of the following taxa are designated: Parnassius simo var. simonius Staudinger, 1889, Parnassius simo var. simulator Staudinger, 1889, Parnassius gylippos Fruhstorfer, 1903, Parnassius simo confusa Bang-Haas, 1927. It is shown that K. anrdeji (Eisner, 1930) is a subspecies of K. simonius and has the oldest available name K. simonius kozlovi Avinov, 1913. New synonyms within K. simo and K. simonius are established.
