Distribution. Japan (Shikoku Island: Ehimé, Kôchi prefectures).

Remarks. The species was originally described in Pterygostegia from Kuroiwa-dô Cave, Ehimé Prefecture, Shikoku Island, Japan, ( Miyosi 1958), later transferred to the genus Diplomaragna ( Shear 1990) , and then it was returned to Pterygostegia ( Mikhaljova 2000) . This species appears to be widespread in limestone caves at the southwestern part of Ehimé Prefecture and at the eastern and western parts of Kôchi Prefecture.
