Description. Male (Holotype). Large harvestman species, body length 7.5 mm long, 3.2 mm width. Body trapezoidal form with an elongated caudal part ( Fig. 3A View FIGURE 3 ). Sand-colored body with lighter and darker spots on the body and a darker pattern on the saddle. Legs, palps and chelicerae are also sand-colored. Body covered with transversal rows of small denticles. Eye mound low with six pairs black-tipped denticles ( Fig. 3B View FIGURE 3 ). Legs long, femora I cylindrical form with transversal rows of black-tipped denticles and setae ( Fig. 3C View FIGURE 3 ). Lengths of leg segments: I: 5.5+1.7+5.0+6.0+8.5 = 26.7; II: 10.5+2.0+8.5+7.0+16.0 = 44.0; III: 5.0+1.7+4.7+6.0+9.4 = 26.8; IV: 7.0+2.0+6.0+7.0+12.0 = 34.0. BLI—1.72. Pedipalp not large, femur dorsally and ventrally with black-tipped denticles and setae, laterally with setae, patella dorsally and laterally with denticles, tibia with denticles on dorsal side and setae, tarsus with setae and ventrally with microdenticles ( Fig. 3D,E View FIGURE 3 ). Pedipalps lengths: 1.7+0.7+0.8+2.0 = 5.2 mm. Chelicera not large, basal segment dorsally with some denticles and setae, distal segments dorsally with denticles and setae ( Fig. 3F,G View FIGURE 3 ). Cheliceral basal segment length 1.7 mm, distal segment 2.1 mm. Penis long with extended base (2.8 mm long, glans 0.4 mm, stylus 0.1 mm). wings slightly expanded ( Fig. 3H, I View FIGURE 3 ). Glans of the penis banana-shapes dorsally with an expanded apical part ( Fig. 3 J, K View FIGURE 3 ).

Female differs by larger body size and oval body shape, smaller chelicera and pedipalps ( Fig. 3L View FIGURE 3 ). Female body length 5.2, wide 3.4. Pedipalp lengths 1.8+0.8+1.0+2.0 = 5.6. Cheliceral basal segment length 1.7, distal segment 2.1. Lengths of leg segments: I: 5.0+2.0+3.8+4.6+8.0 = 23.4; II: 9.2+2.0+8.2+6.6+20.0 = 46.0; III: 4.6+1.6+4.2+5.4+8.6 =1741893102 24.4; IV: 7.0+1.6+6.0+8.0+12.0 = 34.6.

Diagnosis. The new species Opilio ordubadicus sp. nov. very close to Opilio morini Snegovaya, 2016 , but differs from it by the structure of the penis—oval wings (dorsal view) in O. morini and wings narrow at the top and widening towards the bottom in O. ordubadicus [ Snegovaya, 2016: fig. 35; Fig. 3J View FIGURE 3 ]; in the longer and thinner legs of the O.morini , especially the Fe I (5.5 mm in O. ordubadicus vs 8.6 mm in O. morini ) [ Snegovaya, 2016: fig. 24; Fig. 3C View FIGURE 3 ]; BLI: 1.72 in O. ordubadicus vs 2.69 in O. morini .

Etymology. The species is named after the Ordubad, one of the regions of Nakhchivan Autonomous Republic, where its type locality lies.

Distribution. Known only from the type locality in Ordubad district (Nakhchivan AR, Azerbaijan).
