Among the ca 100 known species of Bursaphelenchus, there are a few questionable taxa which share some morphological characters with this genus and other characters with the genera of the subfamily Ektaphelenchinae. B. lini and B. eproctatus are characterized, amongst other features, by having bursa, wide-lumened stylet, well developed oblong median bulb with posterior valve plates, and obscure/non-functional rectum and anus, that is, the same combination of diagnostic characters as B… 
Devibursaphelenchus kheirii sp. n. (Nematoda: Ektaphelenchinae) from Iran with remarks on Devibursaphelenchus Kakuliya, 1967
The molecular phylogenetic analyses were performed using two Bayesian inference (BI) and maximum likelihood (ML) methods and revealed that D. kheirii sp.
Description of Ektaphelenchus oleae n. sp. (Rhabditida: Ektaphelenchinae) from Iran
The new species is typologically similar to species belonging to three genera: Anomyctus, Ektaphelenchus and Seinura by a combination of morphological characters, e.g. head with expanded lips, forming a small bowl-like structure, stylet without knobs or swellings at the base, short conical tail and a vestigial anus and rectum in most individuals.
Description of two Pseudaphelenchus species (Tylenchomorpha: Aphelenchoididae) associated with Asian termites and proposal of Tylaphelenchinae n. subfam.
Molecular phylogenetic analysis based upon near-full-length sequences of the small subunit of the ribosomal RNA gene suggested that Pseudaphelenchus and Tylap Helenchus form a strongly-supported clade at the base of the family Aphelenchoididae, and that Tylanelenchus is included in Pseudapsis as an inner clade.
Seinura caverna n. sp. (Tylenchomorpha: Aphelenchoididae), an androdioecious species isolated from bat guano in a calcareous cave
A molecular phylogenetic analysis based on two small and large subunit ribosomal RNA genes revealed that the new species is located at the basal position of clade 3 of the Aphelenchoididae, clearly separate from S. demani, its congener with unclear rectum and anus, suggesting that further generic revision is necessary for the genus.
Two Ektaphelenchinae Paramonov, 1964 (Nematoda: Rhabditida) from Iran have tripartite stylet, with similar observations in other species
Molecular phylogenetic studies of the two recovered species using small and large subunit ribosomal DNA (SSU and LSU rDNA) partial sequences revealed they have close phylogenetic affinities with Ektaphelenchus obtusus in both reconstructed trees.
Description of Ektaphelenchoides caspiensis n. sp. (Nematoda: Ektaphelenchinae) from Iran
The new species is characterised by its continuous lip region, obscure lateral field, females with body length, 9-10 μm long stylet, excretory pore posterior to base of metacorpus at 62-72  μm from anterior body end, short post-uterine sac ca 0.5 times corresponding body diam, and posterior body end very long and filiform.
Description of Ektaphelenchus berbericus n. sp. (Rhabditida: Ektaphelenchinae) from eastern Iran
The new species was recovered from soil samples collected in eastern Iran and is described and illustrated based on morphological, morphometric and molecular data, and formed a clade with Ektaphelenchoides and Devibursaphelenchus spp.
Description of Ektaphelenchoides fuchsi n. sp. (Nematoda: Ektaphelenchinae) from western Iran.
Ektaphelenchoides fuchsi n. sp., recovered from a soil sample around the rhizosphere of Cucurbita maxima in western Iran, is described and illustrated based on morphological and molecular characters.
Phylogenetic Status of Insect Parasitism in the Subfamily Entaphelenchinae Nickle with Description of Peraphelenchus orientalis n. sp. (Tylenchomorpha: Aphelenchoididae)
A new entaphelenchid species was isolated from the body cavities of burying beetles, Nicrophorus quadripunctatus, with a 14% prevalence and the phylogenetic position of the subfamily within the family Aphelenchoididae was determined using morphological and molecular data for the new species.
Description of Cryptaphelenchus iranicus n. sp. (Nematoda: Ektaphelenchinae) recovered from bark samples of Pinus nigra from Iran.
Phylogenetic analyses using the D2/D3 fragment of 28S rDNA show the new species forming a clade with other Cryptaphelenchus species with maximal Bayesian posterior probability (BPP) in Bayesian inference and 100% bootstrap value (BS) in the maximum likelihood method.
