Morphological and molecular characterisation of Criconemoides brevistylus Singh & Khera, 1976 and C. obtusicaudatus Heyns, 1962 from South Africa (Nematoda: Criconematidae) with first description of a male C. obtusicaudatus and proposal of new synonyms.

Criconemoides brevistylus is described and illustrated from a golf course in KwaZulu-Natal Province. It is compared with several closely related species, and three previously described species ( C. helicus, C. onostris and C. paronostris) are regarded as junior synonyms of C. brevistylus. Criconemoides obtusicaudatus is described and illustrated from a maize field in Limpopo Province. The male of the species is described for the first time. Molecular characterisation of C. brevistylus and C. obtusicaudatus using the D2-D3 expansions segments of 28S rRNA and ITS rRNA gene sequences are provided. Phylogenetic relationships of these species with other Criconemoides are discussedenITS1-5.8S-ITS2Criconemoides onostris n. syn.Criconemoides helicus n. syn.SEMCriconemoides paronostris n. synCriconemoides obtusicaudatusmolecularmorphometricsdescriptionmorphologyphylogenytaxonomyArticle
