Distribution. Gametis ishigakiana ishigakiana. Japan: Ryukyu Islands: Miyako Islands (Tarama-jima Is.) and Yaeyama Islands (Ishigaki-jima Is., Iriomote-jima Is., Hatoma-jima Is., Kohama-jima Is., Taketomi-jima Is., Kuroshima Is., and Aragusuku-jima Is. (= Kamiji-jima Is.)). Gametis ishigakiana miyakoana. Japan: Ryukyu Islands: Miyako Islands (Miyako-jima Is., Ogami-jima Is., Irabu-jima Is., Kurima-jima Is., and Minna-jima Is.). Gametis ishigakiana yonakuniana. Japan: Ryukyu Islands: Yonaguni-jima Is. (Fujioka 2001; Sasaki et al. 2002; Yamazaki et al. 2015; Kusui 2012, 2017, 2019; this study).

Remarks. The subspecies, Gametis ishigakiana miyakoana (Nomura, 1959) (Figs. 22–24) and G. ishigakiana yonakuniana (Nomura, 1959) (Figs. 25–27, 34–35), are herein transferred from G. forticula to G. ishigakiana based on both morphological characteristics and mitochondrial COI gene sequence data.

The three subspecies were described on the same paper by Nomura (1959). Among them, G. f. ishigakiana is the most widely distributed and common. Following recommendation 24A of the International Code of Zoological Nomenclature (ICZN 1999), G. f. ishigakiana is selected here as the nominotypical subspecies under the First Reviser Rule.
