Additional data on some poorly known species of Criconemoides Taylor, 1936 (Nematoda: Criconematidae).

Six known species belonging to the genus Criconemoides, including some poorly known ones, are discussed, viz., C. parvus, C. informis, C. mongolensis, C. avicenniae, C. myungsugae and C. neoaxestis. The three latter species are reported for the first time since their original description and represent new records for Iran. Males of C. myungsugae were found for the first time and are described herein. Additional figures and measurements are provided for all of the aforementioned species, while SEM photographs, photomicrographs, illustrations and short notes are given for some of the species to supplement older or inadequate descriptions.
