Morphological and molecular characters of Scutellonema brachyurus () from South Africa.

ABSTRACT: During a survey on plant-parasitic nematodes from South Africa, Scutellonema brachyurus was recovered from soil samples collected around the rhizosphere of wild grass in the North West and Limpopo provinces. This species characterized by a hemispherical lip region with four to six annuli, basal lip's annuli with longitudinal incisures, body length 696-904 µm (a = 25.1-33.5; b = 5.0-7.2; c = 48.9-75.3; c' = 0.5-0.9; V = 55-60), stylet 21-27 µm length, tail rounded with 10-19 µm length and spermatheca nonfunctional and male absent. The nblast analysis based on the D2-D3 segment of 28 S rDNA placed South African populations of S. brachyurus with 98% similarity to Greece (KU059494) and 99% similarity to South African (JX472052) S. brachyurus. Besides, nblast of COI of mtDNA showed 98% similari
