English Names

Okinawa Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 109 [based on Rana ulma, then thought to be Rana okinavana]).

Ryukyu Brown Frog (Maeda and Matsui, 1990, Frogs Toads Japan, Ed. 2: 55; Goris and Maeda, 2004, Guide Amph. Rept. Japan: 80 [based Rana ulma and Rana kobai, then thought to be Rana okinavana]).


So far known only from Okinawajima Is. and Kumejima Is. of the Okinawa Island Group, Central Ryukyus, Japan.


Substantial genetic variation among populations is evident according to the original publication. Matsui, 2007, Zool. Sci., Tokyo, 24: 199-204, showed that this species, long misidentified as "Rana okinavana" (actually a senior synonym of Babina psaltes) was unnamed. Shibata and Matsui, 1985, Bull. Osaka Mus. Nat. Hist., 38: 1-4. Maeda and Matsui, 1990, Frogs Toads Japan, Ed. 2: 52-55, provided account as Rana okinavana. Sumida, Ueda, and Nishioka, 2003, Zool. Sci., Tokyo, 20: 567-580, reported on molecular phylogenetic relationships and reproductive incompatability of this species (as Rana okinavana) with other brown frogs in East Asia. Goris and Maeda, 2004, Guide Amph. Rept. Japan: 80-82, provided an account (as Rana okinavana), map, and photograph. See photograph, map, description of geographic range and habitat, and conservation status (as Rana okinavana) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 509. See Rana kobai, which was confused with this species, as Rana okinavana, until recently.
