Etymology. The name is derived from Madagascar, the country from which most records originate.
Diagnosis. C. madagascarense sp. nov. is similar to C. africanum, but females are differentiated by the thinner copulatory ducts (Fig. 90), and males are differentiated by RTA with a single pointed apex (Figs 92–93).
Description. Female: (n = 10): TL = 6.14 (5.1–7.4); CL = 2.53 (2.1–3.1); CW = 1.92 (1.6–2.3); OAL = 0.41 (0.35–0.50); OAW = 1.11 (0.85–1.45); CLL = 0.05 (0.05–0.08). Chelicerae: robust with long fangs; cheliceral fang furrow with six teeth of unequal size, PMT:RMT = 3:3 (Fig. 88). Measurements: AME–AME 0.15; AME–ALE 0.15; AME diameter 0.15; PME–PME 0.20; PME–PLE 0.20; PME diameter 0.15; MOQAW 0.40; MOQPW 0.45; CI (CL/CW) 1.35; LL:CL 3.72; STL 1.30; STW 1.05. Leg measurements: I—2.5+1.0+2.4+2.4+1.0 = 9.3; II—1.9+0.9+1.8+1.8+0.8 = 7.2; III—1.5+0.7+1.1+1.3+0.6 = 5.2; IV—2.1+0.9+1.9+2.2+0.8 = 7.9; palp—0.9+0.4+0.5+0.9 = 2.7. Leg spines: I 0-0-1p, 0, 2v- 0- 1 v; II 0-0-1p, 0, 2v- 0- 1 v; III 0-1p1r-1p1r, 0-1p1r-0, 2v- 1p1r-3 v1 p1r; IV 0-0-1p1r, 0-0-1r, 2 v1 r-1p1r-3 v1 p1r. Abdomen (Fig. 82): creamy-yellow with a slight heartmark.
Epigynum (Figs 89–90): wider than long, with a large transverse central depression; copulatory openings in anterio-lateral sides of depression; internally, copulatory tubes proceed anteriorly, then loop around before turning posteriorly to end anterolaterally in small round spermathecae; fertilization ducts exit spermathecae posteromedially.
Male: (n = 10): TL = 5.65 (5.3–6.4); CL = 2.53 (2.2–2.7); CW = 1.88 (1.6–2.2); OAL = 0.37 (0.35–0.40); OAW = 0.98 (0.8–1.2); CLL = 0.05 (0.05-0.05). Chelicerae: similar to female, except longer, with PMT:RMT = 3:3 (Fig. 91). Measurements: AME–AME 0.10; AME–ALE 0.15; AME diameter 0.15; PME–PME 0.15; PME–PLE 0.15; PME diameter 0.15; MOQAW 0.40; MOQPW 0.45; CI (CL/CW) 1.44; LL:CL 5.62; STL 1.2; STW 1.0. Leg measurements: I—3.7+1.2+4.0+4.2+1.5 = 14.6; II—2.8+1.0+2.1+3.0+1.0 = 9.9; III—1.8+0.8+1.6+2.2+0.8 = 7.2; IV—2.9+1.0+2.6+3.5+1.0 = 11.0; palp—1.2+0.4+0.6+1.1 = 3.3. Leg spines: I 0-1p-1p1r, 2v- 3v-2v, 2v- 1v-1v; II 0- 1p-1p, 1v-1v- 1p, 2v- 1v-1v; III 0-1p1r-1p1r, 0-0-1p1r, 2 v1 p1r-1 v1 p1r-3 v1 p1r; IV 0-1p-1p1r, 1v- 1r-1p1r, 2 v1 p1r- 2 v1 p1r-3 v1 p1r. Abdomen (Fig. 83): slightly more elongate than in female. Palp (Figs 92–93): cymbium elongate, about equal to tibia plus patella length, with apophysis pointing proximally; RTA with a single point at apex; TA sclerotized, swollen distally, with a long point next to CON at apex; in some cases the TA also have a small point at the apex on the retrolateral side; EM long, almost encircling tegulum, ending at CON apex; CON unsclerotised but distinct.
Distribution. Comoros and Madagascar (Fig. 115).
Habitat. Forest, spiny forest/thicket, dry forests, littoral forests, plantations and cultivated lands.
