Remarks

Stimpson (1860) briefly described C. brevirostris from Loo Choo (Okinawa) Island. Kubo (1941) redescribed it based on specimens from Ishigaki Island, and transferred it to the genus Neocaridina . Cai et al. (2006), however, synonymized C. brevirostris with Atyoida pilipes as no Neocaridina species have been found from Okinawa Island and the only form that fits well with Stimpson’s description of C. brevirostris around Okinawa Island is Atyoida pilipes ( Newport, 1847) . Therefore, Kubo’s (1941) N. brevirostris is in fact, an unnamed species. This uncertain species is morphologically very close to the short rostrum form of the Neocaridina iriomotensis , new species, but could be distinguished by the shorter rostrum (not reaching to the end of the basal segment of antennular peduncle vs. reaches to or slightly beyond); the pterygostomian angle rounded (vs. with small spine); the stout carapace (1.2 vs. 1.5 times as long as high) and the large egg size (1.5×0.9 vs. 1.00–1.20× 0.6–0.8 mm).

Distribution

Known only from Ishigaki Island.
