discussion
Remarks. The specimens of Sphenanthias whiteheadi were collected off the coast of Tuticorin in the Gulf of Mannar at a depth of 220 – 350 m by deep-sea shrimp trawler. The holotype and three paratypes were collected at Quilon, north of Tuticorin, along the southeast coast of India. This species may prove to be more widespread along the Indian coast. (n = 8)
