摘要:
2021年5月于南海中层渔业资源调查中采集保存鱼类样本1尾,依据其形态特征,鉴定为克氏蛇牙龙鰧(Kali kerberti)。蛇牙龙鰧属(Kali)隶属于鲈形目,叉齿鱼科,其突出特征为:体延长、侧扁,口大;前颌骨和齿骨具齿2行,内列齿向后弯曲、獠牙状;下颌前端联合处未骨质化;体裸露、无皮刺。克氏蛇牙龙鰧鉴别特征为:颅骨脆弱,上下颌弯曲、具鳃耙;前颌骨内列齿和齿骨中列齿显著延长、獠牙状;前颌骨内列齿5~6枚,其中4~5枚獠牙状齿;齿骨内列齿4~5枚。该调查首次在南海采集到蛇牙龙鰧属克氏蛇牙龙鰧,为南海的新记录属和新记录种,可为南海叉齿鱼科鱼类的研究提供资料。

Abstract:
One mesopelagic fish specimen has been collected in May, 2021, from the South China Sea (SCS). Checked with morphological characters it is identified as Kali kerberti. The genus Kali belongs to family Chiasmodontidae in order Perciformes. The diagnosed characteristics are read as follows, body elongate, laterally compressed, mouth large, premaxillary and dentary teethes two rows and the internal row recurved and flanged, bony projection at tip of chin absent, body naked, dermal spinules absent. The characteristics of K. kerberti are identified as cranium with fragile bones, upper and lower jaws strongly curved, gill rakers present, teeth in mesial series of premaxilla and dentary remarkably elongated, fang-like, teeth in mesial series of premaxilla 5-6, including 4-5 fangs, mesial row of dentary teeth 4-5. This is the first time that the specimen of K. kerberti ever collected from the SCS and also the first record of genus kali and species K. kerberti in SCS. This work provides information for further study of the Chiasmodontidae in SCS.
