A new species of Camallanidae (Raillet and Henry, 1917) from a siluroid catfish in Barak River, Jiribam, Manipur (India)
Based on the two Camallanid gravid females recovered from the intestine of siluroid catfish Aorichthys aor (Hamilton, 1822) in Barak River, Jiribam, Manipur, India, Procamallanus (Spirocamallanus) jiriensis n. sp. is described. It is morphologically characterized by 20–24 (9-incomplete) spiral thickenings (ridges), occupying posterior 2/3rd of the buccal capsule. The present species differs from its closely related species Procamallanus (Spirocamallanus) chauhani (Sahay in Indian J Helminthol 18(2):114–122, 1966) in many aspects such as two pair of teeth antero laterally present in oral cavity, a pair of finger-shaped thickenings, which is laterally present at the buccal capsule, presence of well-developed globular vulvar lips, vagina directed posteriorly from vulva, a small conical spike-like projection at the rounded tail tip with well-developed caudal muscles and papillae.
