- Helicotylenchus talonus Siddiqi, 1972 (Fig. 1, I–J and Image 5 A–B) Material examined: 3 females, 31.xii.2009; coll. P. Bohra, Reg.No. IV/2344. Measurements: Females: L = 0.41–0.46 mm; a = 22–24; b = 5.8–6.5; c = 1.1–1.2; c ́ = 0.8–0.9; V = 62–66. Description: Female: Body spirally curved upon fixation. Lateral fields marked by four incisures. Lip region hemispheroid, distinctly marked by 4–5 labial annules. Stylet 19–20μm long; basal knobs large with flattened to concave anterior surface–median oesophageal bulb oval. Ovaries paired. Tail dorsally convex–conoid, with 3–7 annules ventrally and a large, bluntly rounded, claw–like unstriated ventral projection. Habitat and locality: Collected from soil around roots of Lemon (Citrus reticulate) at Kakarwa, Rajasamand District, Rajasthan, India. Remarks: H. talonus Siddiqi, 1972 comes close to H. glissus Thorne & Malek, 1968; H. bradys Thorne & Malek, 1968 and H. borinquensis Roman, 1965. From H. glissus it differs in having a distinctly annulated lip region, a wider tail projection and inner incisures of the lateral fields usually fusing distally on tail. From H. bradys it can be differentiated by spear length (spear 29–33 μ long in H. bradys), finer body annules (3μ wide at mid– body in H. bradys) and fewer tail annules. From H. borinquensis it can be separated by its fewer tail annules, a large tail projection and phasmids which are closer to the anal level.
