I have just received a pdf of a new paper elevating five subspecies of Papilionidae to species status. No new names are introduced.
Nakae, M. 2021. Taxonomic revision on five species of the family Papilionidae (Lepidoptera). Gekkan Mushi, 602: 35-39.
Based upon long time field investigation experience mainly in tropical countries and scientific study, five taxa previously placed as subspecies of different species in family Papilionidae are here elevated to species. Byasa mukoyamai Nakae, 2015 from B. hedistus (Jordan, 1928); Byasa ravana (Moore, ) from B. dasarada (Moore, ); Papilio arjuna Horsfield, 1828 and P. tamilana Moore, 1881 from P. paris Linnaeus, 1758; and Papilio echidna Boisduval, 1836 from P. clytia Linnaeus, 1758.
I can provide copies for personal use on request. Please either send an e-mail or PM, rather than posting a request in the thread.
