Type material. Holotype: ♂ (UBCZ; SWK12-0488; KYU-SAL600), MALAYSIA: Sarawak, Bako National Park, Ulu Assam Trail, 1.712– 1.713°N, 110.445– 110.448°E, 30–80 m elev., 8 March 2012, leg. W.P. Maddison, E.K. Piascik, A. Ang & C. Lee, WPM#12-005. Paratype: 1♀ (UBCZ; KYU-SAL601), same data as holotype.
Etymology. The specific epithet is in honor of Freddie Mercury (1946–1991), the leader of the British band “Queen”. Many classic rock songs he wrote accompanied the growth of the first author.
Diagnosis. It can be distinguished from all other congeners by its bowl-like extension on the retrolateral side of tip of RTA (Fig. 169).
Description. Male (Holotype). Habitus as shown in Fig. 160. Measurements of holotype: carapace length 1.77; abdomen length 1.38; measurements of eyes: AME 0.31, ALE 0.22, PME 0.08, PLE 0.19; measurements of legs: I 3.23 (1.06, 0.67, 0.66, 0.49, 0.35), II 2.38 (0.80, 0.43, 0.46, 0.38, 0.31), III 2.50 (0.88, 0.38, 0.42, 0.51, 0.31), IV 2.74 (0.90, 0.40, 0.55, 0.53, 0.36); leg formula 1432. Carapace red brown to dark brown and abdomen brown, with rather sparse and short pale setae dorsally, two flanks and posterior part of carapace and area around muscle impression of abdomen bare, upper edge of AME lens with small orange setae sticked on. Legs dark but proximal tibiae IV, proximal metatarsi III–IV and tarsi III–IV lighter, with sparse short and pale setae on dorso-distal femora, dorsal patellae, dorso-proximal tibiae and slightly on dorso-proximal metatarsi.
Palp (Figs 162–164): embolus with many small grooves scored on basal part along embolic extension direction; RTA long and forward bending, lobe on tip of RTA rough, with many denticles on outer edge, embedded in bowl-like extension on tip of RTA.
Female. Habitus as shown in Fig. 161. Measurements of paratype: carapace length 1.57; abdomen length 1.78; measurements of eyes: AME 0.33, ALE 0.22, PME 0.08, PLE 0.18; measurements of legs: I 2.51 (0.85, 0.52, 0.51, 0.28, 0.35), II 2.23 (0.76, 0.42, 0.42, 0.31, 0.32), III 2.46 (0.85, 0.35, 0.48, 0.43, 0.35), IV 2.85 (0.91, 0.39, 0.61, 0.57, 0.37); leg formula 4132. Body and legs dark, without obvious pale setae; dorsal abdomen relatively smooth, with three pairs of muscle impression, and slight indigo and purple reflection.
Epigynum (Fig. 166): atria small and far from each other. Vulva (Fig. 167): median part of copulatory ducts touched, covering inner margins of spermathecae in ventral view, bottom margin of copulatory ducts almost at same level to bottom margin of spermathecae; spermathecae subspherical, one bridge-like cutinized band connecting two fertilization ducts (Fig. 172).
Distribution. Malaysia (Sarawak).
