DHS 37 (34).
Gnathosoma (Figs. 18–20): Six pairs of ventral hypostomal setae longitudinally aligned (vh1–vh6) (Fig. 18); hypostome terminates in two lateral lips, bearing two adoral setae ad1 9 (9), ad2 12 (13) and with sparsely longitudinal striations, which are transverse at base. Chelicera (Fig. 19) with longitudinal striae and with two setae, distal seta 80 (76) longer than proximal seta 55 (52); movable and fixed digit smooth, straight and of same length. Palp (Fig. 20) chaetotaxy: trochanter 0, basifemur 7sts, telofemur 1sts, genu 4sts, tibiotarsus 3sts, 1s, 2 long end setae (VES, DES).
Dorsum (Figs. 21–23): at and pt slender and nude (Fig. 21). Center of prodorsum with continuous to sparsely broken longitudinal striations (Fig. 21); two internal apodemes present (Fig. 21); two pairs of eyes posterolateral to pt with transverse striae between each pair present. Setae lps closer to at than to pt. Dorsal striae of hysterosoma with continuous to sparsely broken striae (Fig. 22); dorsal setae smooth to minutely barbed (Fig. 23).
Venter (Figs. 24–26): Ventral setae nude (Fig. 24); genital plates each with 9 setae longitudinally aligned; 10 aggenital setae present (Fig. 25); anal valves with 3 pairs of smooth pseudanal setae (ps1–ps3), ps1 68 (62), ps2 51 (51), ps3 48 (45); with 1 pair of setae (v1) between coxae IV. Ovipositor (Fig. 26) present and has 12 subapical and 6 medial setae.
Legs (Figs. 27–30): Leg chaetotaxy: coxae I–IV 6 (5)-5-6(7)-4sts; trochantera I–IV 1-1 -2-1sts; basifemora I– IV 8 (7)-7(8)-6(7)-3sts; telofemora I–IV 7-7 -8-7sts; genua I–IV 7 sts, 1duplex (dxs), 1asl- 8sts, 1duplex- 8sts, 1duplex- 8sts, 1duplex; tibiae I–IV 8 sts, 2asl, 1pe, 1T- 9sts, 1asl, 1bsl- 9sts, 1asl- 8sts, 1T; tarsi I–IV 27 (28)sts, 2asl, 2bsl, 1pe–26(25)sts, 2bsl–24sts, 1T–23sts, 1asl, 1T.
Male and Immature stages. Unknown
Remarks. Bdella farabii Paktinat-Saeej & Bagheri sp. nov. is similar to B. muscorum Ewing 1909, B. kuznetsovi Maslov & Khaustov 2013, and B. longistriata Atyeo 1960. B. farabii sp. nov. is similar to B. muscorum in having duplex setae on genua I–III but can be distinguished by (1) tibiae I with two attenuated solenidia instead of four attenuated solenidia in B. muscorum; (2) genua IV with duplex setae which is absent in B. muscorum; (3) prodorsum with longitudinal striations instead of transverse striations in B. muscorum; (4) tarsus II in new species lacks the peg; (5) internal apodemes in new species weakly developed vs. distinctly developed apodemes in B. muscorum. B. farabii sp. nov. resembles B. kuznetsovi in having weakly developed internal apodemes and longitudinal striations on prodorsum but can be distinguished by (1) genua I–IV with duplex setae which is absent in B. kuznetsovi; (2) tibiae I with two attenuated solenidia and one peg vs. four attenuated solenidia and without peg in B. kuznetsovi; (3) tarsus II in new species lacks the peg. B. farabii sp. nov. resembles B. longistriata in having longitudinal striations on the prodorsum and duplex setae on genua I– IV but it can be separated by (1) different palp chaetotaxy; (2) having 9 genital setae on each genital plate vs. 11 setae in B. longistriata; (3) tarsus II in new species lacks the peg; (4) internal apodemes in the new species weakly developed vs. distinctly developed apodemes in B. longistriata.
Etymology. This species is named after“Abu Naṣr Muḥammad Farabi”(872 A.D–950 A.D), who was a Persian writer specializing in political philosophy, metaphysics, ethics, and logic.
Type material. Holotype female was collected from soil and rotten leaves under citrus trees, 30 October 2013, Saeej-Mahalleh village, Amol city, Mazandaran Province, Iran, by Saeed Paktinat-Saeej and one paratype female was collected from the soil and humus under apple trees, 25 September 2014, Azarshahr city, East Azerbaijan Province, Iran by Mansoureh Ahaniazad. The holotype female is deposited in the Acarological Collection, Department of Plant Protection, Faculty of Agriculture, University of Maragheh, Maragheh, Iran and one paratype female is deposited in the Acarological Collection, Acarological Society of Iran (ASI), Department of Plant Protection, Faculty of Agriculture, University of Tehran, Karaj, Iran.
