TYPE LOCALITY AND TYPE REPOSITORY. Sri Lanka, Kandy; FKCP.

TYPE MATERIAL. Sri Lanka, Kandy, IV.2001, 1♂ after fifth ecdysis (holotype, Figs. 208, 219, 235, 250, 259, 378–379, 382, 384–385, 387–389, 394–400, 402, 419), 1♂ 3♀ (paratypes, Figs. 220, 236, 380–381, 383, 386, 390–393, 401, 420, 570), FKCP, leg. V. Fura.

ETYMOLOGY. Named after Prof. Kithsiri B. Ranawana who organized our Sri Lankan expedition.

DIAGNOSIS. Total length 35–43 mm. Male with very slightly longer metasomal segments than female. Pedipalp segments and telson approximately the same length and width in both sexes. Pedipalp movable finger longer than manus of chela in both sexes. Pedipalps and legs with brown maculation, identical on femur and patella. First metasomal segment with 10 carinae, second through fourth segments with eight carinae, fifth segment with five carinae in female and three to five in male. Posterior terminal tubercle of each dorsal carina on metasomal segments of both sexes scarcely larger than preceding tubercles. Subaculear tooth wide and rounded, dorsally with granules in four rows; six symmetrical granules in three rows and one or two granules on tip. Ratio metasomal segment II length/ width 1.78– 1.80 in male. Glabrous zone stretching over almost whole posterior margin of fifth sternite. Pectinal teeth number 12–14 in both sexes.

DESCRIPTION. Total length 35–43 mm. The habitus is shown in Figs. 378–381. For measurements and ratios see Tables 4–5. For positions and distribution of trichobothria see Figs. 395–400. The male has very slightly longer metasomal segments than the female. Length and width of the telson is approximately the same in both sexes (Figs. 419–420).

Coloration (Figs. 378–381). Base color reddish, with brown to black spots. Chelicera strongly reticulated mainly anteriorly, with spotted fingers. Ventral surface of mesosoma and pedipalps yellowish brown with a pair of black spots mainly on the sixth and seventh sternites. The carapace and pedipalps dorsally and laterally yellowish to reddish, with brown to black spots, identical on pedipalp femur, patella and manus. Pedipalp fingers reddish black. Legs with the same color and pattern as the pedipalp femur and patella. Metasomal segments and telson are yellowish to reddish with spots.

Mesosoma and carapace (Figs. 382–386). Carapace without carinae but with large granules. Tergites I–VI with one granulated median carina, tergite VII pentacarinate. Fifth sternite with glabrous zone stretching over almost the whole posterior margin. Seventh sternite with four incomplete carinae, sparsely granulate. Pectinal tooth count 12–14 in females, 13–14 in males. Pectines with three marginal lamellae and six to seven middle lamellae. The lamellae bear numerous pale setae.

Metasoma and telson (Figs. 219–220, 387–392, 419– 420). The first metasomal segment bears 10 carinae and the second to the fourth segments bear eight carinae, the fifth segment bears five carinae developed in both sexes.

Ventral carina present on telson. Intercarinal surfaces of metasoma granulated, including dorsal surface. In both sexes, posterior terminal tubercle of each dorsal carina on metasomal segments not enlarged. Telson elongate, with subaculear tooth wide and rounded, dorsally with granules in four rows; six symmetrical granules in three rows and one or two granules on the tip.

Pedipalps (Figs. 235–236, 393–400). Femur and patella only very sparsely hirsute, with complete carinae, granulated. Chela manus in both sexes granulated, with dorsal carinae indicated. Sixth row of granules on movable finger with one external granule. Seventh row of granules on the fixed finger without additional granules.

Legs (Fig. 208). Femur and patella with complete carinae, granulated. Legs hirsute, without bristle combs.

AFFINITIES. The described features distinguish R. ranawanai sp. n. from all other species of the genus. All other Sri Lankan Reddyanus species exhibit sexual dimorphism in the length of the telson, which is absent in R. ranawanai sp. n. (c.f. Figs. 419–420 versus Figs. 409–418).
