New insights into the taxonomy and the evolutionary relationships of the rare nematode genus Ferris & Ferris, 1973 (Nematoda, Dorylaimida, Belondiridae), after the molecular characterization of an Iranian population of its type species.

A new Iranian population of is characterized, including morphometrics, microphotographs, and molecular (18S, 28S rDNA) studies. It is compared with previously known populations. The results derived from molecular analyses failed to find close evolutionary relationships with other traditional genera of Belondiridae and Swangeriinae, adding more uncertainties about the internal phylogeny of the family.

Guidelines for species descriptions of free-living aquatic nematodes: characters, measurements and their presentation in taxonomic publications.

Free-living aquatic nematodes are abundant, diverse and of general environmental importance. However, knowledge of species distributions of both marine and freshwater nematodes is sparse. Species distribution data are crucial for evaluating environmental impacts from human activities and to conduct integrated nematode community assessments.

Cyber catalogue and revision of the nematode genus (Dorylaimida, Nordiidae).

Background: The genus is an intriguing free-living dorylaimid nematode taxon. Its representatives display a distinct distributional pattern as they are mainly spread in high altitudinal enclaves of the Northern Hemisphere, being often associated with mosses and cliff vegetation. Although their feeding habits have not been studied with experimental protocols, it is traditionally assumed that they are omnivorous.
