description
From B. elegans it differs by the shorter body (584 – 748 vs 750 - 900 µm), finer body annules (0.5 – 1.0 vs 1.5 – 1.7 µm), higher a ratio (37 – 42 vs 30 – 36), shorter tail (151 – 181 vs 192 – 218 µm), higher c' ratio (14.3 – 17.2 vs 13), higher V´ ratio (77 – 79 vs 74 – 75) and, tail shape: filiform with pointed terminus in B. birjandiensis n. sp. but conoid with rounded terminus in B. elegans. It differs from B. dolichura by shorter body length (584 – 748 vs 820 – 930 µm), longer stylet (11 – 12 vs 9 – 11 µm), shorter tail (151 – 181 vs 220 – 276 µm), lower c ' ratio (14.3 – 17.2 vs 16 – 23), higher V ratio (57 – 60 vs 52 – 57) and shorter post vulval uterine sac (8 – 14 vs 15 – 16 µm). It differs from B. jirians by longer stylet length (11 – 12 vs 8 – 9 µm), longer tail (151 – 181 vs 130 – 136 µm), lower V and V' ratio (57 – 60 vs 61 – 62 and 77 – 79 vs 83 respectively) and the position of the excretory pore: 78 – 91 µm from the anterior end in B. birjandiensis n. sp. vs 64 – 66 µm in B. jirians. A list of species of the family Tylenchidae recorded to date from Iran, as well as additional data on their morphometrics, geographical distributions and associated plants, is given below:
description
Measurements (Table 1). Female. Body almost straight to slightly curved ventrally after fixation, 584 – 748 µm (660.6 ± 72.3). Cuticle with fine annuli, 0.5 – 1.0 µm (0.6 ± 0.1) wide at mid body. Lateral fields with four incisures (1 / 3 of body width). Lip region high, flat at apex, not set off, non – striated, 2 – 4 µm (3.4 ± 0.4) high and 5 – 7 µm (6.3 ± 0.5) wide at the base. Stylet with rounded knobs, 11 – 12 µm in length. Dorsal gland orifice located 6 – 9 µm posterior to stylet base. Amphidial aperture usually oblique and slit – like. Median bulb oval, weakly developed, 5 – 8 µm wide and 8 – 14 µm long. Terminal bulb pyriform, 6 – 12 µm wide and 15 – 27 µm long. Pharyngo – intestinal valve flattened. Excretory pore located from isthmus level to the middle of the basal bulb, 78 – 91 µm from anterior end of the body. Deirids present in middle of lateral field, positioned at level of excretory pore. Postvulval uterine sac 8 – 14 µm (10.7 ± 1.9) long. Spermatheca filled with sperm and offset. Tail filiform, 151 – 181 µm (164.1 ± 13.5), with pointed terminus. Male. Similar to female, but body shorter, 475 – 583 µm (529 ± 76.5), shorter tail, 93 – 119 µm (106 ± 18.4) and lower c´= 8 – 9.7 (9 ± 0.9). Spicules ventrally curved, 18 – 19 µm (18.5 ± 0.6), gubernaculum slightly curved about 4 – 5 µm (4.7 ± 0.3).
diagnosis
Diagnosis. B. birjandiensis n. sp. is differentiated from other Basiria species by its shorter body length (584 – 748 µm [660.6 ± 72.3]), high lip region with flat apex, stylet 11 – 12 µm (11.3 ± 0.5), cuticle with fine annuli (0.5 – 1 µm wide), V = 57 – 60 (58.5 ± 0.8), V´= 77 – 79 (78 ± 0.7), filiform tail, 151 – 181 µm (164.1 ± 13.5), c ratio 3.7 – 4.2 (3.9 ± 0.1) and higher c´ value (14.3 – 17.2 [15.1 ± 0.9]). Relationships. The new species shares an anteriorly situated median bulb and pyriform basal bulb with B. elegans (Khan & Khan 1975) Bajaj & Bhatti 1979, B. dolichura Loof 1971 and B. jirians Renubala & Dhanachand 1992, but it differs as follows:
etymology
Etymology. From “ Birjand ” (the centre of the South Khorasan province) and – ensis (a Latin adjectival suffix, meaning “ originating in ”). Habitat and locality. Collected from the rhizosphere of Ziziphus zizyphus in South Khorasan province, Iran.

Type material. Holotype (code number: MaUNS 111) and four paratypes (three slides, code numbers MaUNS 112 – 114 [three females], one slide, code number MaUNS 115 [one male]) deposited in the nematode collection of the Department of Plant Protection, College of Agriculture, Ferdowsi University of Mashhad (Mashhad, Iran). Paratypes code number WT 3661 [one female], code number WT 3662 [one female, one male], WT 3663 [two females] and WT 3664 [one juvenile, one female] at the Wageningen Nematode Collection, Plant Protection Organization (Wageningen, The Netherlands).
