Abstract

The species composition of batoid fishes from coastal waters of the Socotra Archipelago is reviewed, with confirmed records of the wedgefish Rhynchobatus djiddensis (Forsskål, 1775) and four new records of sharkrays, wedgefishes, and guitarfishes based on collected specimens, including one species from Abd al-Kuri Island, Rhina ancylostoma Bloch Schneider, 1801 (Rhinidae), and three species from the main island Socotra, Acroteriobatus salalah (Randall Compagno, 1995) and Rhinobatos punctifer Compagno Randall, 1987 (Rhinobatidae), and Rhynchobatus australiae Whitley, 1939 (Rhinidae). Among the new records for the Socotra Archipelago, R. australiae represents the first verified record for the Arabian region. In addition, records of four stingray species (Dasyatidae) are verified based on underwater observations accompanied with photographs. All recorded batoid fishes are commercial species caught in the local small-scale fishery. Information on the identification and distribution of each species is provided.

摘要

对索科特拉群岛沿海水域的鳐形目鱼类的物种组成进行了回顾，根据采集的标本，确认了楔形鱼 Rhynchobatus djiddensis（Forsskål，1775）和 4 种新的鲨鱼、楔形鱼和吉他鱼的记录，包括 Abd al-Kuri 岛的一种 Rhina ancylostoma Bloch Schneider，1801（Rhinidae），以及主岛索科特拉的 3 种 Acroteriobatus salalah（Randall Compagno，1995）和 Rhinobatos punctifer Compagno Randall，1987（Rhinobatidae），以及 Rhynchobatus australiae Whitley，1939（Rhinidae）。在索科特拉群岛的新记录中，R. australiae 是阿拉伯地区的首次确认记录。此外，还根据水下观察和照片，证实了 4 种黄貂鱼（Dasyatidae）的记录。所有记录的鳐形目鱼类都是在当地小规模渔业中捕获的商业物种。提供了每种物种的识别和分布信息。
