TYPE LOCALITY AND TYPE REPOSITORY. Malaysia, Kelantan Dabong, Gunung Stong, 05°20'34.5"N 101°58'41.4"E, 125 m a. s. l.; FKCP.
TYPE MATERIAL. Malaysia, Kelantan Dabong, Gunung Stong, 05°20'34.5"N 101°58'41.4"E, 125 m a. s. l., 30.VIII.2016, 1♂ (holotype) 1♀ 2juvs. (paratypes), leg. D. Hoferek, FKCP.
ETYMOLOGY. The species epithet is a patronym honoring David Hoferek, the collector of types of the new species. He is also the author of the photograph of type locality (Fig. 71).
DIAGNOSIS. Adult from 31 mm (female) to 35 mm (male) long. Male has longer metasomal segments and telson. Legs and metasoma yellow, with brown spots. Base coloration of pedipalp yellow with dark spots, identical on femur and patella. Manus of pedipalps yellow with black spots, fingers black. Metasoma V and partly IV and telson black in male. First metasomal segment bears 10 carinae, second through fourth bear eight carinae, lateral carinae on metasoma II represented only by several granules in posterior part. Metasoma V bears five carinae which can be reduced. Terminal tubercle on second and third metasomal segments of male slightly enlarged. Telson elongate in male, shorter in female. Subaculear tooth large but not rounded, dorsally with 3–4 granules in two rows. Pectinal teeth number 11 in male, 10 in female.
DESCRIPTION. The adults are 31 mm (female paratype) – 35.32 mm (male holotype) long. The habitus is shown in Figs. 37– 40. For position and distribution of trichobothria of pedipalps see Figs. 52–55, and 57–58. Sexual dimorphism: adult male with longer and narrow metasomal segments and telson.
Coloration (Figs. 37–40). The base color is yellow with dark spots. The chelicera is yellow, strongly reticulated. The fingers of chelicerae are spotted. The carapace and mesosoma are with a pattern that forms three dark longitudinal strips. The tergits with two symmetrical yellow spots on posterior part. The ventral side of the mesosoma is reddish brown. Base coloration of pedipalp yellow with dark spots, identical on femur and patella. The legs are also yellow with large black spots. The metasoma I–III is yellowish or redish brown with black spots, metasoma IV–V is black in male and reddish black and spotted in female.
Carapace and mesosoma (Figs. 37–48). The entire carapace is covered with large granules; carinae are absent. The anterior margin of the carapace is medially convex. The mesosoma bears one median carina and is strongly granulated. Tergite VII is pentacarinate. The pectinal tooth count is 11 in male holotype and 10 in female paratype. The two subadult paratypes have 10–11 pectinal tooth. The pectine marginal tips extend to the end of the third sternite in the male and to the third quorter of the third sternite in the female. The pectines have three marginal lamellae and 8–9 middle lamellae. The lamellae and fulcra bear numerous light setae. Sternites are smooth with two parallel furrows except sternite VII which bears four incomplete carinae and is smooth. The glabrous zone in the middle of the posterior margin of sternite V present in both sexes.
Metasoma and telson (Figs. 41–42, 61–66). The first segment bears 10 carinae. The metasoma II–IV bear eight carinae, lateral carinae on metasoma II represented only by several granules in posterior part. The fifth segment bears five carinae from which the dorsal in male are reduced. Ventral carina is present on the telson in male and ventral and lateral in female. Surfaces between carinae are obviously smooth, with small, sparse granules that become more numerous on metasoma I– II in female. Terminal tubercle on the second and the third metasomal segments of both sexes only very slightly enlarged. The telson elongate in male, shorter in female. Subaculear tooth not rounded, dorsally with 3–4 granules in two rows.
Pedipalps (Figs. 49–60). The pedipalps are very sparsely hirsute. The femur bears five and patella seven granulated carina. The chela is with four granulated carinae in both sexes. The chela and patella are slightly and femur is densely granulated. Movable finger with six and fixed finger with seven rows of granules, both with several accessory granules and 6 external and 5 internal accessory granules.
Legs (Figs. 67–70). The legs without tibial spurs. The tibia and tarsomeres of legs with setae not arranged into bristle combs on dorsal surfaces. Tarsomere II of leg IV with two sparse rows of <20 spiniform setae on ventral surface. The femur bears 3–4 and patella, 5 carinae; both femur and patella are granulated.
Measurements. See Table 1.
AFFINITIES. The described features distinguish R. hofereki sp. n. from all other species of the genus. They are recounted in the key. Morphologically closest species is R. krasenskyi from Java, which differs mainly by the darker pedipalp patella and more elongate metasomal segments in male (Figs. 194 versus 196).
DISTRIBUTION. Malaysia (Fig. 225).
