Depth range Upper intertidal zone of uplifted coral reef. [details]

Distribution Pacific Ocean: Kume-jima (Ryukyu Islands, southern Japan). [details]

Etymology The specific epithet kumensis is an adjective derived from the name of the type locality, Kume-jima. [details]

Habitat Sandy bottom with pebbles in a small creek originating from a freshwater spring within the upper intertidal zone of the uplifted coral reef, surrounded by salt-marsh vegetation. The habitat condition of the species was judged as living usually under fresh-water conditions, changing drastically to a marine regime during the most extreme spring high tides for a few days in a month, with salinities ranging from 0.2 to 33.1 psu and temperatures from 19.2°C to 22.6°C (measured in November 2013). [details]

Reproduction Coelom of two paratypes collected in March 2007 filled with large oocytes (about 250 μm and 150 μm, respectively, in maximum diameter). None of the studied specimens showed epitokous metamorphosis. [details]

Type locality Gushicha Gusuku, on Kume-jima Island, Okinawa Prefecture, central Ryukyu Islands, southern Japan, Pacific Ocean (26.3814°, 126.7542°).  [details]
