Morphological and molecular analysis based on sequence of the 18S rDNA of Mononchoides adjunctus Massey, 1966 (Nematoda: Neodiplogasteridae) from Iran.

摘要

Mononchoides adjunctus Massey, 1966 was isolated during a survey on free-living nematodes belonged to the family Neodiplogasteridae from a natural lawn in south-eastern Iran, near to Lout desert, in Kerman province. This population of Mononchoides is characterised by a dorsal claw-like tooth 2 micro m long and 1 micro m wide, 15 longitudinal ridges on the female body, a uterine sac associated with two dumbbell-shaped pouches, small spicules (19-25 micro m long), a short gubernaculum (11-14 micro m or less than half of the spicule length), two pairs precloacal papillae, five pairs postcloacal papillae, papillae (GP5) comprising of three small papillae, and a long filiform tail (154-171 micro m in females, 110-137 micro m in males). Molecular analysis of M. adjunctus based on sequence of the 18S rDNA placed it together with Tylopharynx foetidus (EU306343) as sister group. Measurements, illustrations and phylogenetic position of M. adjunctus and closely related species are given.
