Sperata seenghala (Sykes, 1839) the Giant river-catfish, is one of the largest freshwater catfish of Indian sub-continent and commonly called as singhara and seenghala. Catfish is a favourite food fish due to its palatability with high nutritional value. S. seenghala (25–27 cm in length) were procured from Chamkaur Sahib, a sub divisional town in the district of Rupnagar in the Indian State of Punjab. Prominent pale, thread-like plasmodia of Hennegoides seenghalae n. sp. were observed on the gills and histological examination located them in the epithelial lining of the gill filament (Intrafilamental epithelial type, FE). The prevalence was 32% (12 fish were infected out of 37 examined). The total myxospore length of He. seenghalae was 46.6 μm with myxospore body length 7.5 μm strongly vaulted from one side with caudal appendage length of 39.1 (25.5–45) μm. The myxospores were closely compared morphologically with five known species of the genus from Indo-Malayan region and another recently reported from the USA. Molecular analysis based on 18S rDNA sequence (1947bp) indicated 80%–91% sequence similarity with other myxozoan parasites (Myxobolus, Henneguya, Hennegoides and Unicauda). The most closely related species was Hennegoides pangasii, and was placed with the present species in the same subclade. The present study is the first report the genus Hennegoides from India.

Sperata seenghala（Sykes，1839）巨河-鱼是印度次大陆最大的淡水water鱼之一，通常被称为singhara和seeghala。fish鱼因其适口性和高营养价值而成为最受欢迎的食用鱼。S. seenghala（长25–27 cm）是从印度旁遮普邦Rupnagar区的一个分区城镇Chamkaur Sahib采购的。Hennegoides seenghalae n。的突出的苍白，线状纤毛虫。sp。在the上观察并组织学检查将其定位在g丝的上皮衬里（丝内上皮类型，FE）。患病率为32％（在检查的37种鱼中有12条被感染）。He的总粘孢子长度。Seeghalae直径为46.6μm，粘孢子体长7.5μm从一侧强烈拱起，尾附肢长为39.1（25.5-45）μm。在形态上将粘孢子与来自印度-马来亚地区的五个已知属和最近从美国报道的另一个属进行了密切比较。基于18S rDNA序列（1947bp）的分子分析表明，其与其他粘虫寄生虫（Myxobolus，Henneguya，Hennegoides和Unicauda）的序列相似性为80％–91％。最密切相关的物种是Hennegoides pangasii，并且与本物种一起置于同一子区域。本研究是来自印度的Hennegoides属的第一个报道。
