The name is a patronym in honour of the collector of the holotype , B. Ranson. Diagnosis. C. ransoni sp. nov. is similar to C. leucopheaum , in the two parts of the female spermathecae being next to each other and the short CA and RTA of the males, but is differentiated from C. leucophaeum by the tube between the two parts of the female spermathecae being straight and not U-shaped (compare Fig. 103 with fig. 73 in Lotz 2007a ). Males are differentiated by the short RTA with a single pointed apex and the CA being slightly longer and more U-shaped ( Figs 105–106 ). Description. Female : (n = 3): TL = 6.77 (6.4–7.4); CL = 2.90 (2.6–3.3); CW = 2.03 (2.0–2.1); OAL = 0.33 (0.30–0.35); OAW = 1.30 (1.3–1.3); CLL = 0.10 (0.10–0.10). Chelicerae: robust with long fangs; cheliceral fang furrow with six teeth of unequal size, PMT:RMT = 3:3 ( Fig. 101 ). Measurements: AME–AME 0.20; AME–ALE 0.20; AME diameter 0.15; PME–PME 0.25; PME–PLE 0.25; PME diameter 0.15; MOQAW 0.50; MOQPW 0.55; CI (CL/CW) 1.57; LL:CL 2.94; STL 1.3; STW 1.2. Leg measurements: I—2.5+1.0+2.5+2.6+1.1 = 9.7; II—2.0+1.0+1.6+1.9+0.8 = 7.3; III—1.6+0.9+1.1+1.5+0.6 = 5.7; IV—2.3+1.0+1.8+2.2+0.8 = 8.1; palp—1.0+0.4+0.6+0.9 = 2.9. Leg spines: I 0-0-1p, 2v-2v- 0, 2v-2 v1 p1r- 2v ; II 0-1p-1p, 0-1 v1 p-0, 2v-2 v1 p1r- 3v ; III 0-1p-1p1r, 0-1p1r-0, 2v-2 v1 p1r-3 v1 p1r; IV 0-0-1p1r, 1r-0-1p1r, 2v-2 v1 p1r-3 v1 p1r. Abdomen ( Fig. 97 ): creamy-yellow with a slight heartmark. Epigynum ( Figs 102–103 ): wider than long, with two depressions separated by a broad median septum; copulatory openings situated in anterior sides of depressions; internally, short copulatory ducts proceed laterally to end medially in compact dumbbell-shaped spermathecae; fertilization ducts exit spermathecae posteromedially. Male : (n = 10): TL = 5.77 (4.4–7.0); CL = 2.56 (1.9–3.1); CW = 1.93 (1.4–2.4); OAL = 0.36 (0.25–0.50); OAW = 1.19 (0.7–1.6); CLL = 0.84 (0.05–0.10). Chelicerae: similar to female, except longer and with PMT:RMT = 1–4:3–5 ( Fig. 104 ). Measurements: AME–AME 0.20; AME–ALE 0.35; AME diameter 0.20; PME–PME 0.30; PME–PLE 0.40; PME diameter 0.17; MOQAW 0.60; MOQPW 0.64; CI (CL/CW) 1.29; LL:CL 4.52; STL 1.7; STW 1.5. Leg measurements: I—3.4+1.3+3.7+4.2+1.4 = 14.0; II—2.5+1.1+2.5+2.6+1.0 = 9.7; III—2.0+0.9+1.5+2.1+0.9 = 7.4; IV—2.7+1.1+2.5+3.1+1.0 = 10.4; palp—1.4+0.5+0.9+0.9 = 3.7. Leg spines: I 0- 1p-1p, 2v-2v- 0, 2v- 2v-3v ; II 0-1p-1p, 2v-2v- 0, 2v-2 v1 p- 3v ; III 0-1p1r-1p1r, 1v- 1p1r-0, 2v- 1p1r-3 v1 p1r; IV 0- 1p1r-1p1r, 1 v1 p1r-1p1r-0, 2 v1 p1r-2 v1 p1r-3 v1 p1r. Abdomen ( Fig. 98 ): slightly more elongate than in female. Palp ( Figs 105–106 ): cymbium elongated, about equal to or slightly longer than, tibia length, with a short, broad; apophysis pointing laterally; RTA short and broad, with a single blunt point at apex; TA unsclerotized, long and bent at apex; EM semicircular, on posterior and prolateral sides of tegulum, ending at CON apex; CON unsclerotized but distinct. Distribution. Several localities on the eastern side of Madagascar ( Fig. 117 ). Habitat. Forest, spiny forest/thicket, dry forests to high altitude rainforests.
