¨ zdikmen, 2008 comprises Abstract Neoalbionella O 10 accepted species, which all infect sharks of Squaliformes and Carcharhiniformes. Adult females belonging to species of Neoalbionella, based on the maxillule palp armed with three setae and the maxilliped subchela claw with only one secondary denticle, were collected from sharks off the coast of South Africa. Neoalbionella izawai n. sp. collected from the anterodorsal part of the spiracle opening of Centrophorus moluccensis Bleeker differs from its congeners by having maxillae that are separated except at the tapering tips where they are fused and that are longer than the trunk, uropods originating from the pointed posterior margin of the trunk and that are well developed, and maxillipeds without an additional spine at the base of the subchela barb. Neoalbionella etmopteri (Yamaguti, 1939) is herein reported from two new hosts (Etmopterus spp.) off South Africa.

Introduction ¨ zdikmen, 2008 (Lernaeopodidae Neoalbionella O Milne Edwards, 1840) comprises 10 species: N. globosa (Leigh-Sharpe, 1918); N. centroscyllii (Hansen, 1923); N. longicaudata (Hansen, 1923); N. etmopteri (Yamaguti, 1939); N. oviformis (Shiino, 1956); N. tenuis (Castro-Romero & Baeza-Kuroki, 1986); N. fabricii (Rubec & Hogans, 1988); N. kabatai (Benz & Izawa, 1990); N. benzipirata Ruiz & Bullard in Ruiz, Driggers & Bullard, 2019 and N. dannytangi Ruiz & Bullard, 2019 (see Ruiz & Bullard, 2019; Ruiz et al., 2019; Dippenaar, 2020). Three innominate species exist according to Ruiz et al. (2019). These lernaeopodids infect sharks of Carcharhiniformes (Pentanchidae, Scyliorhinidae and Triakidae) and Squaliformes (Centrophoridae, Etmopteridae and Squalidae) (Castro-Romero & Baeza-Kuroki, 1986; Ruiz et al., 2019). Females of species of Neoalbionella resemble those of Lernaeopoda von Nordmann, 1832 (see Kabata, 1979) but can be distinguished based upon the morphology of the maxillule palp (armed with 3 setae in Neoalbionella spp. vs 2 in Lernaeopoda spp.) and the number of secondary denticles on the maxilliped subchela claw (1 in Neoalbionella spp. vs 2 or more in Lernaeopoda spp.) (see Ruiz et al., 2019). Males are more readily distinguishable (Kab
