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.
