First Record of Stripe-faced Calamiana Eugnathogobius Mindora (Herre, 1945) in India, and Distribution Range Extension of Banded Mullet goby Hemigobius hoevenii (Bleeker, 1851) and Acentrogobius viganensis (Steindachner, 1893) (Gobiiformes: Gobiidae) Collected from Pazhaverkaadu Lagoon and Ennore Estuary, South India

The present work reports the occurrence of stripe-faced calamiana Eugnathogobius mindora (n = 2) for the first time in Indian waters and distribution range extension of Hemigobius hoevenii (n = 1) and Acentrogobius viganensis (n = 1) which co-occurs with E. mindora along the east coast of India. The specimens were collected from the Pazhaverkaadu lagoon and Ennore estuary, South India. E. Mindora can be readily distinguished from its closest congeners in having five prominent brown stripes in cheek and suborbital, elongations in first three dorsal spines, 33–36 lateral scales and a larger anterior nape scale. The present finding adds one more species to the Indian fish fauna by reporting the first species of the genus Eugnathogobius from Indian coastal waters. Description, meristic and morphometric characters provided for the three gobiid fish species in this study will aid to solve the ambiguity in their identities as these species have spatial synonyms in the tropical marine waters.

印度条纹面 Calamiana Eugnathogobius Mindora (Herre, 1945) 的首次记录,以及带状鲻鱼虾虎鱼 Hemigobius hoevenii (Bleeker, 1851) 和 Acentrogobius viganensis (Steindachner, 1893) 的分布范围扩展南印度恩诺尔河口

目前的工作报告了印度水域首次出现的条纹面卡拉米亚纳Eugnathogobius mindora ( n = 2 ) 和Hemigobius hoevenii ( n = 1 ) 和Acentrogobius viganensis ( n = 1 ) 与印度东海岸的E. mindora 。这些标本采集自印度南部的 Pazhaverkaadu 泻湖和 Ennore 河口。E. Mindora可以很容易地将其与其最接近的同类区分开来,因为在脸颊和眼眶下有五个突出的棕色条纹,前三个背棘伸长,33-36个侧鳞和更大的前颈鳞。目前的发现通过报告来自印度沿海水域的Eugnathogobius属的第一个物种,为印度鱼类动物群增加了一个物种。本研究中为三种戈壁鱼提供的描述、分类和形态特征将有助于解决它们身份的歧义,因为这些物种在热带海水中具有空间同义词。
