Abstract

A new estuarine moray eel, Uropterygiushades sp. nov., is described based on 14 specimens from Japan, Taiwan, the Philippines, southern Indonesia, and Fiji. It is a small-bodied, slender, uniformly dark-brown moray separated from congeners within the U.concolor species complex. The new species can be distinguished from congeners by the anteriorly positioned small eyes (5.0-7.2% of head length), absence of branchial pores, and extended inner rows of teeth which reach the posterior end of the jaws. Uropterygiushades sp. nov. represents a rare species of moray eel that inhabits turbid estuarine environments, preferring soft, muddy substrates, and burrowing and hiding among rocks or in fallen mangrove leaves. Additionally, Uropterygiusmactanensis Huang, Balisco, Evacitas & Liao, another species recently separated from the U.concolor species complex, is reported for the first time from Iriomote Island in the Ryukyu Archipelago based on two specimens; this new record expands the geographic range of U.mactanensis from the central Philippines to southern Japan.

来自中印度洋-太平洋的一种新的统一的棕色河口海鳗(鳗鲡目,鳗科)的Description。
根据日本、台湾、菲律宾、印度尼西亚南部和斐济的14个标本,描述了一种新的河口海鳗,Uropterygiushades sp. nov.。它是一种体型小,细长,均匀的深棕色海鳗,从同系物中分离出来。新物种可以通过位于头部前方的小眼睛(占头部长度的5.0-7.2%),没有鳃孔和延伸的内排牙齿来与同类区分开来,这些牙齿延伸到颌骨的后端。Uropterygiushades sp. 11 .是一种罕见的海鳗,栖息在浑浊的河口环境中,喜欢柔软、泥泞的基质,在岩石或红树林落叶中挖掘和隐藏。此外,在琉球群岛Iriomote岛首次报道了从U.concolor物种复合体中分离出来的另一种Uropterygiusmactanensis Huang, Balisco, Evacitas & Liao;这一新记录扩大了U.mactanensis的地理范围,从菲律宾中部到日本南部。
