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,

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 (
