This contribution provides data for four species of the superfamily Aphelenchoidea from Iran. Aphelenchoides paramonovi was recovered from decaying wood and bark samples collected from Golestan province, north Iran. It is characterized by 434-671 μm long females, five lines in the lateral fields, a finger-like mucron with a short bristle in tail terminus and males with 17-22 μm long spicules. Paraphelenchus myceliophthorus has 610-752 μm long females with 16-17 μm long stylet, two mucrons at tail tip and males with 23-26 μm long spicules. A conical tail, not ending to ventrally bent narrow tip was observed in a population of Bursaphelenchus mazandaranense recovered from Golestan province, as a new variation of tail morphology for the species. The two latter populations were sequenced for their partial large subunit ribosomal DNA (LSU rDNA D2-D3). Cryptaphelenchus varicaudatus, was isolated from haemocoel of the bark beetle Orthotomicus erosus, collected from Tehran province. The morphometric data and light microphotographs were provided for all the studied species.
