ETYMOLOGY. The species epithet is a patronym honoring Shahrokh Navidpour (Iran) for his friendship and lifelong dedication to arachnids.  
 DIAGNOSIS. Total length of adult 28–43 mm. Trichobothrium d 2 of pedipalp femur dorsal surface present. Median to long tibial spurs present on legs III and IV. Pectinal teeth number 20–23 in males and 18–20 in females. Movable and fixed fingers of pedipalps with 9 rows of denticles, with internal and external denticles and 5 subterminal denticles. Pedipalp patella carinae dorsal granulate. Metasoma I with 10 carinae, metasoma II with 8 carinae. Metasoma IV–V ventrally punctate with ventrolateral carinae absent or incomplete; spaces among punctae smooth, without granules. Metasoma II–III ventrally and laterally coarsely granulate, partly punctate and bumpy. Dorsal surface of metasoma I with several granules, metasoma II–IV smooth, and metasoma V mesially with several granules. Sternite VII densely granulate, with granulate carinae present. Pedipalp, metasoma and telson very sparsely hirsute, rather glabrous. Tarsomere I of legs without bristlecombs. Ratio length/width of metasoma V in males 1.05–1.15.   
DESCRIPTION. Total length of adults is 28–43 mm in both sexes. Measurements of the carapace, telson, segments of the metasoma and segments of the pedipalps are given in Table 2. For habitus see Figs. 117–120.  
 Coloration (Figs. 117–120). Carapace, tergites, metasoma and femur of pedipalps and legs are black, tibia and tarsomeres of legs and fingers of pedipalps are yellow. Patella of legs and pedipalps and pedipalp chela can be brown to black. Sternite VII is black, other sternites are reddish brown to black obviously with yellow median zone present in posterior margin of sternites III–VI. Telson is reddish black.   
 Mesosoma and carapace (Figs. 121–124). The mesosoma bears a median carina and is densely granulated. The carapace is densely granulated, including the middle of interocular triangle. Only anterior median carinae are indicated, which are granulated. The seventh sternite is granulated and bears four granulated carinae, the other sternites are finely granulated except the smooth median glabrous zones, with a pair of smooth carinae. Pectinal teeth number 20–23 in males and 18–20 in females.   
 Metasoma and telson (Figs. 129–134). The segment I bears 10 granulated carinae. The segments II–V lacks lateral carinae, ventromedian carinae are present on metasoma I–III, ventrolateral carinae are present on metasoma I–III, absent or incomplete on metasoma IV–V, dorsolateral carina is present on metasoma I–IV and present or reduced on metasoma V. Metasoma I is densely granulated laterally, metasoma II–III laterally with several granules, granulation absent on ventral surfaces of metasoma IV–V. Dorsal surface of metasoma I with several granules, metasoma II–IV smooth, and metasoma V mesially with several granules. Metasomal segments IV–V are densely punctate, less so metasoma II– IV ventrally. Spaces among punctae on metasoma IV–V are smooth. The entire metasoma and telson are only very sparsely hirsute, rather glabrous. The telson is punctate and lacks granules.   
 Pedipalps (Figs. 135–154).The distance between trichobothria  d 1  and  d 3  on the femur of pedipalp approximately equals that between  d 3  and  d 4 ; trichobothrium  e 1  is situated between  d 3  and  d 4 . Trichobothrium d 2 of pedipalp femur dorsal surface is present. The femur of pedipalp bears five granulate carinae. The patella has seven carinae from the dorsal are granulated, and the chela has smooth carinae, which may be discernible throughout the length of the fixed finger. The entire pedipalps are only sparsely hirsute. The movable fingers bear 9 rows of denticles, with external and internal denticles and 5 subterminal denticles.   
 Legs (Figs. 125–128). The femur bears four partly granulated carinae, the patella bears five rather smooth carinae, and the tibia is smooth. The patella bears only a few spiniform setae. The tibia bears spiniform setae. Tarsomere I without bristlecombs, there are usually only 3 longer spiniform setae. Tersomeres I–II of all legs with two rather irregular rows of spiniform setae.   
 AFFINITIES. The described features distinguish Orthochirus navidpouri sp. n. from all other species of the genus. Navidpour et al. (2010) formerly cited populations of the new species as O. iranus according to the previously used complex of characters. A detailed comparison done in this study shows morphological differences between these two species, which are evident from our comparative photoplates. These two species can be morphologically unequivocally separated by the following features: (1) Metasoma V dorsal mesially densely granulated in O. iranus (Fig. 159) vs. mesially with only several granules in O. navidpouri sp. n. (Fig. 161); (2) Ventral and lateral surfaces of metasoma IV–V are granulated in O. iranus (Fig. 173) vs. smooth in O. navidpouri sp. n. (Fig. 134); (3) Pedipalp patella dorsal carinae, mainly the dorsomedian carina, granulated in O. navidpouri sp. n. (Fig. 168) vs. smooth in O. iranus (Fig. 166). For differentiating of O. navidpouri sp. n. from all other Orthochirus species of the region, see the key below.
