X. kesarii sp.n. collected from the rhizosphere of Fig (Ficus carica L.) from Horticulture Farm, RCA, Udaipur is characterized by having:L = 3.040–3.875mm; a = 54.28–65.12; b = 7.85–10.70; c = 66.93–94.51; c = 1.108–1.48; V = 45.12–50.98%; Odontostylet length = 127.5–140 μm; Odontophore length = 51–75.5 μm; total stylet length = 178.5–215.0 μm; Guiding ring = 92.5–115.2 μm; Tail length = 39–48 μm; cylindrical body with tapering ends, gonads didelphic, amphidelphic with vulva located just at middle of the body and sub-digitate tail. Xiphinema udaipurensis sp.n. collected around the rihizosphere of Pomegranate (Punicagranatum) from Krishi Vigyan Kendra, Badgaon around Udaipur city, is characterized by having L = 2.24–2.40; a = 42.14–43.07; b = 5.97–6.40; c = 30.68–32.02; c = 2.77–3.31; V =30.26–40.40%; Odontostylet length = 95.5–100.0 μm; Odontophore length = 51–60 μm; total stylet length = 151.0–155.5 μm; guiding ring = 70–77 μm; Tail length = 73–75 μm; posteriorly ventrally arcuate body, rounded and slightly offset head with well developed spear. Gonads didelphic, amphidelphic but vulva anterior and long ventrally conoid tail.
