Diagnosis of larva – SD 85–90, Ta I 122–132, Ta II 100–107, Ta III 122–127, Ti III 110–122, Fe II 82–87, Fe III 100–107.
Description of larva (n = 3)
Dorsum ( Figs. 1 View Figure 1 , 2 View Figures 2–3 ) – Idiosoma 235–275 long and 127–162 wide. Dorsum of idiosoma with 32 dorsal barbed setae, arranged in 5 oblique rows: 6-6-6-6-8, fD =32. Scutum almost ovoid in shape and flattened between levels of AL and PL setae, punctate from posterior margin to level of AM bases, bearing 3 pairs of normal setae (AM, AL and PL) and 1 pair of sensilla (S). Setae AM and PL subequal in length and slightly longer than AL setae, there is a slight concavity anterior to each AM seta, all scutalae barbed. Sensilla flagelliform, slender and entirely nude. Posterolaterally on each side of scutum 2 eyes situated on common ocular plate (23–26 long, 15–17 wide), anterior lens (diameter 12–13) slightly larger than posterior one (diameter 8–10).
Venter ( Fig. 3 View Figures 2–3 ) – Idiosoma ventrally with 2 pairs of barbed sternal setae (1a and 3a) and 15 pairs of barbed ventral setae (fV = 30) behind coxa III, and a uropore. Coxa I with distal antero-lateral seta 1b, supracoxal seta absent; coxa II with approximately anteromedial seta 2b; coxa III with seta 3b
approximately antero-medially; all coxalae barbed; coxae I–III each punctate. Claparède's organs between coxae I and II, circular. NDV = 32 + 30 = 62 (in all specimens).
Gnathosoma ( Figs. 4–6 View Figures 4‒6 ) – Cheliceral bases punctate on dorsal surface, cheliceral base 83–85 long; cheliceral blade slightly curved, 20–21 long, with a median and subterminal teeth. Adoral seta cs 10–11 long and nude, one pair of barbed subcapitular setae (bs), 25–40 long; palpfemur 35–42 and palpgenu 35–42 long, each with one barbed dorsal seta. Palptibia 26–35 with two barbed and one nude seta; palpal tibial claw slender, bifurcate, 6–9 long; palptarsus 9–12 with 4 barbed and 3 nude setae (one barbed setae longer than the others), and a solenidion; fPp = 0-B-B-BBN 2 -4B3Nω. Palpal supracoxal setae absent.

Type deposition
The holotype and paratype larvae are deposited in the Acarological Collec-tion, Jalal Afshar Zoological Museum ( JAZM), Department of Plant Protection , Faculty of Agri-culture , University of Tehran, Karaj, Iran .
Etymology The specific epithet is derived from the type locality, Birjand city. Remarks
The new species belongs to the genus Nothrotrombidium in having sensillary setae arising behind middle of scutum, a little behind level of AL setae; coxal setae formula 1-1-1; pedotarsal claws 1-1- 1 and cheliceral bases long and slender.
Nothrotrombidium birjandensis sp. nov. differs from N. otiorum in shorter SD (85–90 vs. 90– 109), Ta I (L) (122–132 vs. 160), Ti I (72–93 vs. 122), Fe I (92–95 vs. 116), Ta II (100–107 vs. 136), Ti II (60–75 vs. 100), Fe II (82–87 vs. 122), Ta III (122–127 vs. 160), Ti III (110–122 vs. 188), Fe III (100–107 vs. 145) and differs from N. treati in the low number of ventral setae, fV (30 vs. 38), in shorter PW (45–51 vs. 62), ASB (50–52 vs. 78), PSB (35–37 vs. 44), SD (85–90 vs. 122), W (55–67 vs. 76), AP (25–27 vs. 35), Ta I (L) (122–132 vs. 151), Ta II (L) (100–107 vs. 125), Fe II (82–87 vs. 100), Ta III (L) (122–127 vs. 146), Ti III (110–122 vs. 145), Fe III (100–107 vs. 118) and IP (1283– 1379 vs. 1550) ( Table 1).
Leg setal formula has not been reported for N. otiorum and N. treati in detail and thus no comparison with the new species is possible.
