The October 2022 description of a new subspecies of Papilio bianor [sic] from Kerama Islands, Okinawa, Japan, has just come to my attention since it was published in Gekkan-Mushi, a hard to obtain journal mainly covering beetles.

The citation is:
Hitoshi Arita & Yasushi Sorimachi 2022. Description of a new subspecies of Papilio bianor Cramer, [1777] from Kerama Islands, Okinawa, Japan. Gekkan-Mushi, 620: 27-29.

Of course this taxon does not actually belong to Papilio bianor but is a subspecies of P. ryukyuensis and was named keramana by Arita & Sorimachi.

A few days ago I was made aware of this by a collector who bought one on eBay and asked me about it. I have just received the original description so can confirm the details here.

So there might be three subspecies of Papilio ryukyuensis right now (nominated, ssp.amamiensis, and ssp. keramana)? How can I get the e-copy of this literature, please? I cannot find it from the website >_<

I have sent a copy to you.

Adam.

Thank you Adam, you are so kind ^0^, and I will learn this literature carefully.

Hi Adam

Could you send me a reprint too?

Thnx
