Francis Day described Pethia punctata from Cochin, on the Malabar (south western) coast of India. Although, the species is now recovered from its synonymy with P. ticto, an accurate diagnosis and description have been lacking. A redescription of P. punctata based on external morphology, osteology and genetics is provided, which revealed that P. muvattupuzhaensis, described from Muvattupuzha River, Ernakulam District, Kerala, India, is its junior synonym. Pethia punctata can be diagnosed from other known species in the genus by a combination of characters including lateral line complete, with 23-25 pored scales; 8 predorsal scales; ½4/1/3½ scales in transverse line; dorsal fin originating almost opposite to, or slightly before pelvic-fin origin; gill rakers 7 on first ceratobranchial; 4+26 total vertebrae; a small black humeral spot covering anterior half of the fourth scale of the row below the lateral-line row; two minute dark spots below the humeral spot; a prominent spot on the caudal peduncle, surrounded by a golden hoop covering scales 19-21 of the lateral-line row; and dorsal fin with 2-3 longitudinal rows of black spots, third row occupying only anterior portion of the fin.
弗朗西斯·戴(Francis Day)描述了采自印度马拉巴尔(西南)海岸科钦的斑鳍波鱼(Pethia punctata)。尽管该物种现已从与细纹波鱼(P. ticto)的同物异名中恢复,但一直缺乏准确的诊断和描述。本文基于外部形态、骨骼学和遗传学对斑鳍波鱼进行了重新描述,结果表明,采自印度喀拉拉邦埃纳库拉姆区穆瓦图普扎河的穆瓦图普扎波鱼(P. muvattupuzhaensis)是其次异名。斑鳍波鱼可通过以下特征组合与该属其他已知物种相区分:侧线完整,有23 - 25个有孔鳞片;背鳍前有8个鳞片;横向有½4/1/3½个鳞片;背鳍起点几乎与腹鳍起点相对,或略在腹鳍起点之前;第一角鳃骨上有7个鳃耙;共有4 + 26枚椎骨;一个黑色的小肩斑覆盖侧线下方一排鳞片的第四枚鳞片的前半部分;肩斑下方有两个微小的黑斑;尾柄上有一个明显的斑点,周围有一个金色环,覆盖侧线一排鳞片的第19 - 21枚鳞片;背鳍有2 - 3排纵向黑点,第三排仅占据鳍的前部。
