Description of Triaenorhina burti n. sp. (Cestoda: Paruterinidae) from the Malabar trogon Harpactes fasciatus (Pennant) (Aves: Trogoniformes: Trogonidae) in Sri Lanka.
Triaenorhina burti n. sp. (Cyclophyllidea: Paruterinidae) is described from Harpactes fasciatus (Trogoniformes: Trogonidae) from the Southern Province of Sri Lanka. The new species is characterised by: a body 24-32 mm long; 44 rostellar hooks alternating in two closely adjacent regular rows, with lengths of 63-65 microm (anterior row) and 39-41 microm (posterior row); regularly alternating genital pores; testes divided into two groups by the ovary and vitellarium; a gravid uterus forming a single oval sac; and a cylindrical paruterine organ not reaching the anterior proglottis margin. A key to the seven recognised species of Triaenorhina Spasskii & Shumilo, 1965 is presented.
