“…Based on the available phylogeny results, it may be concluded that Nothotylenchus species are composed of divergent lineages. This has been reflected in their feeding habits as well, e.g., N. antricolus was found in the rotten pieces of decaying wood in a cave [47], N. boroki and N. tenuis, in the deadwood materials of pine and Birch [12], and N. drymocolus and N. petilus, in insect frass [11,54]. Considering this, we anticipate that a genus-wide phylogenetic analysis would shed more light on the ecology and biology of these nematodes.…”

The nematode family, Anguinidae, is a diverse group of polyphagous nematodes, generally known as fungal feeders or parasites of aerial plant parts. Here, we present the morphological and molecular characterization of adult females of two Nothotylenchus species, N. medians and N. similis, along with host association and geographical distribution data of the genus. Both species are recorded as new reports from Canada and designated as reference populations for future studies. Morphological or morphometrical variation was not observed in the Canadian population of N. medians and N. similis, in comparison with the original description. Phylogenetic analyses based on 18S and D2–D3 of 28S genes placed both species within Anguinidae. Since the biology of the genus Nothotylenchus has not been rigorously characterized, the habitat and distribution information presented in this study will shed some light on the ecology of these nematodes. Notably, the detection of N. medians and N. similis in our nematode inventory survey indicates that considerable Nothotylenchus diversity is hidden in these soils. Consequently, increased surveys and more in-depth research are needed to explore the full diversity of anguinids inhabiting these cultivated areas.

“…The lip region in Boleodorus species is smooth and without striations or annulation. Almost all the species are described as exhibiting a lip region continuous with the body contour, however some speciessuch as B. cylindricus Dhanachand, Renubala, and Anandi [36], B. filiformis, B. innuptus Andrassy [37], B. modicus Lal and Khan [38], B. punici Gambhir and Dhanachand [39], B. solomonensis Ye and Geraert [40], B. spiralis Egunjobi [41], B. tenuis Lal and Khan [38], B. thylactus, and B. volutus-are reported to have an offset lip region, though this offset is not by constriction or strong depression at the lip region.…”

The present study provides the morphological and molecular characterization of Boleodorus thylactus and B. volutus populations, recovered from agricultural fields of southern Alberta. Despite a significant abundance of this group of nematodes, none of the Boleodorus species were previously reported in Canada. Therefore, representative adult specimens of each population were photographed and examined morphometrically. Phylogenetic trees were reconstructed using partial D2–D3 expansion segments of the 28S and 18S rDNA sequences to understand the relationships of Boleodorus species with Tylenchidae-related genera. Boleodorus species are relevant to soil ecological studies and therefore we summarized the important morphological and morphometric characters in tabular form for easy and efficient species identification. Moreover, we discuss the associated hosts and the distribution of all described Boleodorus species. This study will serve as a guide and basic framework for species diagnostics in the genus Boleodorus and will aid in filling the gaps in our knowledge of the species present in our cultivated lands.

“…It is further characterized by 379–662 μm long females, having 5.8–6.9 μm long stylet with fine posteriorly sloping knobs, no valvate metacorpus, pharyngeal bulb slightly overlapping intestine dorsally, vulva at 76.5–84.0% of body length and males with cloacal bursa. By having an elongated conoid tail and four lines in the lateral fields, the new species comes close to four known species of the genus namely Nothotylenchus acris, N. acutus Khan, 1965 , N. antricolus Andrássy, 1961 and N. truncatus Eliashvili & Vacheishvili, 1980 . The new species could be separated from them as follow:…”

Nothotylenchus savadkoohensis n. sp. was recovered from rotten wood samples of an unidentified forest tree in the Mazandaran province and described herein. It is mainly characterized by an elongated conoid tail ending in a sharply pointed tip and four lines in the lateral field. Females of the new species have 379–662 μm long bodies with 5.8–6.9 μm long stylets ending in fine posteriorly sloping knobs, the metacorpus not valvate, the pharyngeal bulb slightly overlapping the intestine, and the vulva at 76.5–84.0% of body length. Males are also common and have 13.0–14.5 μm long spicules and bursa cloacal. By having an elongated conoid tail and four lines in the lateral field, the new species comes close to four known species, namely N. acris, N. acutus, N. antricolus, and N. truncatus. The morphological differences between the new species and the abovementioned species are discussed. The new species was sequenced for its D2–D3 segment of LSU and ITS rDNA regions. In the LSU phylogenetic tree, the currently available LSU sequences of the genus Nothotylenchus occupied distant placements from each other and the LSU sequence of the new species formed clade with a sequence assigned to Neotylenchus sp. In ITS phylogeny, the newly generated sequence of the new species formed a clade with a clade that includes sequences of Ditylenchus sp. and Neomisticius platypi and N. variabilis.
