Abstract
Review of type specimens of some species of Ecphyadophora and Ecphyadophoroides plus new collections of others revealed one new species of Ecphyadophora, three new species of Ecphyadophoroides and reaffirmed the distinction of three separate genera : Ecphyadophora, Ecphyadophoroides and Epicharinema. Elongate amphidial slits or clefts on dorso-ventrally flattened cephalic regions characterize Ecphyadophoroides, whereas rounded heads with four symmetrical lobes annulate almost to the labial plate and bearing small pore-like amphids distinguish Ecphyadophora. Tylenchus eurycephalus De Man, 1921 is judged to be Ecphyadophoroides eurycephalus (De Man, 1921) n. comb, but assigned to species inquirendae. Ecphyadophora iarjani could not be confirmed as a separate species or a synonym of Ecphyadophora quadralata so is placed in species inquirendae. Ecphyadophora acuta, E. basiri, E. goodeyi and E. tritici are judged synomyms of Ecphyadophora quadrafata. Ecphyadophora teres n. sp., Ecphyadophoroides sheri n. sp., Ecphyadophoroides macrocephalus n. sp. and Ecphyadophoroides leptocephalus n. sp. are described. Amended diagnoses are proposed for Ecphyadophorinae and its three genera. Keys to species of Ecphyadophora and Ecphyadophoroides are provided.
