Type material. Holotype: ♂ ( UBCZ; KYU-SAL700), MALAYSIA: Sarawak, Mulu Nat. Pk., headquarters area, 4.042°N, 114.814°E, 50 m elev., 25–27 March 2012, leg. W.P. Maddison, E.K. Piascik & A. Ang, WPM#12-094 GoogleMaps . Paratypes: 1♂ 1♀ ( UBCZ; KYU-SAL701~KYU-SAL702), same data as holotype GoogleMaps ; 1♂ ( UBCZ; KYU-SAL703), MALAYSIA: Sarawak, Mulu Nat. Pk., Canopy Walk , 4.032°N, 114.819°E, 80 m elev., 26 March 2012, leg. W.P. Maddison, E.K. Piascik & A. Ang, WPM#12-099 GoogleMaps .

Etymology. The specific epithet is a noun in apposition from “Yahaha” (also known as “Korok”), a very cute pixie in the game The Legend of Zelda: Breath of the Wild. Yahaha often hide in tree trunks, bushlands, or rocks, and if you find them, they will say “Yahaha!” and share with you some “fruits” as a gift. Collecting Orcevia specimens is very like searching for Yahaha.

Diagnosis. It can be distinguished from all other congeners by its long and baffy-like embolus ( Figs 322 View FIGURES 319–325 , 326 View FIGURES 326–331 ), and the small and ligulate embolic disc which is well defined from the base of embolus ( Fig. 329 View FIGURES 326–331 ). Females resembles O. calcicola sp. nov. in the relatively large atria close to genital furrow; however, they can be distinguished by the copulatory ducts that extend upward first, further down and then connect with spermathecae ( Fig. 331 View FIGURES 326–331 ; vs. CDs extend upwards and directly connect with spermathecae in O. calcicola sp. nov.).

Description. Male. Habitus as shown in Fig. 319 View FIGURES 319–325 . Measurements of holotype: carapace length 1.92; abdomen length 1.64; measurements of eyes: AME 0.40, ALE 0.25, PME 0.06, PLE 0.21; measurements of legs: I 4.21 (1.24, 0.83, 1.03, 0.68, 0.43), II 2.99 (0.93, 0.56, 0.63, 0.53, 0.34), III 3.12 (0.95, 0.49, 0.58, 0.73, 0.37), IV 3.32 (1.00, 0.47, 0.72, 0.75, 0.38); leg formula 1432. Dorsal body covered with dense white setae; legs I–II obviously darker than III–IV.

Palp ( Figs 321–323 View FIGURES 319–325 ): embolus long and baffy-like, distal half with many small protrusions on retrolateral surface; embolic disc small and ligulate, well defined from embolus ( Fig. 329 View FIGURES 326–331 ); lobe-like protrusion of tegulum well developed; tegular lobe well defined from main part of tegulum, with prolateral and retrolateral constrictions close to tegulum; RTA narrow in retrolateral view, bent medially; ventral femoral bump hook-like as in O. zabkai sp. nov. ( Fig. 342 View FIGURES 338–345 ), distal part blunt.

Female. Habitus as shown in Fig. 320 View FIGURES 319–325 . Measurements of paratype: carapace length 1.55; abdomen length 1.66; measurements of eyes: AME 0.33, ALE 0.22, PME 0.04, PLE 0.17; measurements of legs: I 2.41 (0.75, 0.45, 0.53, 0.37, 0.31), II 2.06 (0.68, 0.34, 0.40, 0.37, 0.27), III 2.50 (0.82, 0.36, 0.49, 0.50, 0.33), IV 2.71 (0.87, 0.37, 0.60, 0.55, 0.32); leg formula 4312. Dorsal body covered with dense golden setae; legs relatively light-colored, melanic area indistinct.

Epigynum ( Fig. 324 View FIGURES 319–325 ): Atria close to each other and close to genital furrow; outer edge of copulatory ducts faintly visible. Vulva ( Fig. 325 View FIGURES 319–325 ): Accessory glands rather small, hiden in ventral side of spermathecae and invisible in dorsal view of vulva; copulatory ducts flat and rolled, weakly sclerotized; spermathecae far from each other, fertilization ducts attached on small mound on spermathecae.
