The scientific name kabeyawan (Taiwanese: ku-piah-uan), used as a noun, is an old name of the type locality Checheng, a territory of aboriginal Paiwan people documented in the Dutch occupation period (1624‒ 1662).</p><p>Distribution. Currently only known from the single specimen collected from mouth of Shih-chong River, Pingtung, southern Taiwan at depth about 1 meter.</p><p>Ecological note. The specimen was collected by trap net operated by a local fisherman who targeted on glass eel of Anguilla spp. It was collected together with other snake eels, such as Lamnostoma sp. and Ophichthus sp., and was likely chasing the fish larvae to the river mouth.</p></div>	https://treatment.plazi.org/id/B1188793FFF0FFFBFF0182A4DD9EF752	Public Domain	No known copyright restrictions apply.

The specific name ryukyuensis is derived from the type locality.</p><p>Distribution. Only known from the two specimens collected from shore of Okinawa-jima Island, Ryukyu Islands, Japan.</p><p>Ecological note. The present specimens were collected as stranded specimens caused by the extremely low temperatures by a serous cold wave coming from the Arctic (Hibino et al. 2021). In the type locality, several species of Muraenidae, Ophichthidae, Apogonidae, Syganidae, etc., were also collected at the same time.</p></div>	https://treatment.plazi.org/id/B1188793FFF2FFFFFF018697DBA2F340	Public Domain	No known copyright restrictions apply.
