Etymology. The specific epithet is from “Bokoblin”, a small piggy monster in the game The Legend of Zelda: Breath of the Wild, developed and published by Nintendo. In the Master Mode of this game, Bokoblin commonly has either silver or gold coloration, corresponding to two color-forms observed in the males of the new species; noun in apposition.

Diagnosis. It resembles O. nietzschei sp. nov. in the small and screw-like embolus, but males can be distinguished by the presence of a small ventro-basal femoral bump on palp ( Fig. 36 ; vs. VFB is absent in O. nietzschei sp. nov.), and the revolute tip of RTA ( Figs 32, 34 , 41 ; vs. tip of RTA is flat in O. nietzschei sp. nov.); females can be distinguished by the smoother spermathecae and the accessory glands that are visible in dorsal view of vulva ( Fig. 38 ; vs. spermathecae are relatively rough and AGs are invisible in dorsal view of vulva in O. nietzschei sp. nov.).

Description. Male. Habitus as shown in Fig. 30 . Measurements of paratype (one of KYU-SAL734): carapace length 1.62; abdomen length 1.41; measurements of eyes:AME 0.37, ALE 0.25, PME 0.08, PLE 0.21; measurements of legs: I 3.46 (1.02, 0.63, 0.88, 0.51, 0.42), II 2.44 (0.79, 0.40, 0.50, 0.43, 0.32), III 2.59 (0.88, 0.36, 0.48, 0.52, 0.35), IV 2.72 (0.86, 0.37, 0.56, 0.54, 0.39); leg formula 1432. Carapace dark, widest at front and gradually narrower towards back. Cephalon and dorsal abdomen covered with dense yellow ( Fig. 25 ) or pale grey ( Fig. 24 ) setae; dorsal abdomen with dark patches, at least on median part of each side; setae near eye lens slightly red; legs I slightly darker than legs II–IV, setae on legs sparse.

Palp ( Figs 32–34 , 40–41 ): embolus short and screw-like, embolic disc low, around base of embolus ( Fig. 35 ); lobe-like protrusion of tegulum relatively wide, width as ca. 1/2 of width of tegulum, with small mastoid tip well defined from other part; tegular lobe well defined, with prolateral and retrolateral constrictions close to tegulum ( Figs 32 , 40 ); RTA bent medially, distal part thin and lamina-like, forming a revolute structure ( Fig. 41 ); ventral femoral bump small and tubercle-like ( Fig. 36 ).

Female. Habitus as shown in Fig. 31 . Measurements of paratype (KYU-SAL734): carapace length 1.51; abdomen length 1.46; measurements of eyes: AME 0.35, ALE 0.22, PME 0.06, PLE 0.19; measurements of legs: I 2.30 (0.74, 0.42, 0.52, 0.36, 0.26), II 2.04 (0.70, 0.36, 0.42, 0.30, 0.26), III 2.27 (0.76, 0.30, 0.47, 0.43, 0.31), IV 2.59 (0.83, 0.34, 0.55, 0.54, 0.33); leg formula 4132. Body dark, setae on dorsal body sparser than male ( Figs 28–29 ). Legs I slightly darker than legs II–IV.

Epigynum ( Fig. 37 ): atria close to each other, with ratio of distance between atria to diameter of atria about 1: 3 ~ 1: 2; atria far from genital furrow, with ratio of distance between lower edge of atria and genital furrow to diameter of atria about 2: 1. Vulva ( Figs 38–39 ): starting part of copulatory ducts wide, with section connecting spermathecae narrowed; accessory glands tubular and pointing sideways, attached on joint of copulatory ducts and spermathecae; spermathecae kidney-shaped, fertilization ducts attached on mound on spermathecae.

Variation. Males from Lambir Hills Nat. Pk. have dense pale grey setae on dorsal body, whereas these setae are yellow in males from Mulu Nat. Pk.; setae on dorsal body of female are relatively sparse in the population of Lambir Hills Nat. Pk., but obviously dense in the population of Mulu Nat. Pk. ( Figs 28–29 ). These variations are considered intraspecific since no difference in genitalia has been observed between these two populations.

Distribution. Malaysia ( Sarawak).
