This paper reports the occurrence of two stingray species from Andaman waters, India; the zonetail butterfly ray Gymnura zonura (Bleeker, 1852) (695 mm DW) which represents a new distributional range, and the mangrove stingray Urogymnus granulatus (Macleay 1883) (395 mm DW) which represents a rare occurrence. These occurrences suggest hidden stingray diversity in this region. Morphological descriptions of both species, as well as a molecular barcode of G. zonura, were generated in the present study to clarify the taxonomic information. The current report assists in improving the understanding of the local diversity and distribution of batoids in Andaman waters, which is crucial for developing fishery management strategies.

本文报道了印度安达曼水域中两种黄貂鱼的发生。分布较广的区域尾butterfly蝶射线Gymnura zonura（Bleeker，1852）（695 mm DW）和罕见的红树林黄貂鱼Urogymnus granulatus（Macleay 1883）（395 mm DW）。这些事件表明该地区存在隐藏的黄貂鱼多样性。在本研究中生成了这两种物种的形态学描述以及松果线虫的分子条形码，以阐明分类学信息。本报告有助于增进对安达曼水域中类蝙蝠的多样性和分布的了解，这对于制定渔业管理战略至关重要。
