Etymology. The name is a patronym in honour of the collector of the holotype, Rudy Jocqué.

Diagnosis. Females of C. jocquei sp. nov. are differentiated by the convoluted copulatory ducts (Fig. 77). Males are differentiated by RTA with a double pointed apex, and the long and double pointed TA (Figs 79–80).

Description. Female: (n = 4): TL = 6.68 (5.9–8.5); CL = 2.50 (2.3–2.9); CW = 2.00 (1.9–2.1); OAL = 0.39 (0.35–0.40); OAW = 1.06 (1.0–1.1); CLL = 0.05 (0.05–0.05). Chelicerae: robust with long fangs; cheliceral fang furrow with six teeth of unequal size, PMT:RMT = 3:3 (Fig. 75). Measurements: AME–AME 0.15; AME–ALE 0.20; AME diameter 0.15; PME–PME 0.20; PME–PLE 0.25; PME diameter 0.15; MOQAW 0.40; MOQPW 0.50; CI (CL/CW) 1.38; LL:CL 5.21; STL 1.4; STW 1.2. Leg measurements: I—4.0+1.3+4.3+4.3+1.2 = 15.1; II—2.8+1.0+2.8+2.8+1.0 = 10.4; III—1.9+0.9+1.6+2.0+0.9 = 7.3; IV—2.8+1.1+2.5+3.1+1.0 = 10.5; palp—1.2+0.5+0.8+1.1 = 3.6. Leg spines: I 0-1p1r-1p1r, 2v-2 v1 p1r-1p1r, 2 v1 p1r-2 v1 p1r-1 v1 p1r; II 0-1p1r-1p1r, 1p1r-1v-1 v1 p, 2 v1 p1r-2 v1 p1r-1 v1 p1r; III 0-1p1r-1p1r, 1p1r-1p1r, 2 v1 p1r-2 v1 p1r-3 v1 p1r; IV 0-1p1r-1p1r, 1v- 1p1r-1p1r, 2 v1 p1r-2 v1 p1r-3 v1 p1r. Abdomen ( Fig. 59 View FIGURES 55 – 60 ): creamy-yellow with a heartmark. Epigynum (Figs 76–77): wider than long, with a broad transverse central depression; copulatory openings in the lateral sides of the depression; internally, copulatory tubes proceed anteriorly, curving medially before turning posteriorly after a series of loops to end anteriorly in round spermathecae; fertilization ducts exit spermathecae posteromedially.

Male: (n = 4): TL = 6.50 (6.0–8.0); CL = 2.83 (2.5–3.5); CW = 2.11 (1.85–2.60); OAL = 0.40 (0.35–0.45); OAW = 1.13 (1.0–1.5); CLL = 0.06 (0.05–0.10). Chelicerae: similar to female, except longer, with PMT:RMT = 3:3 (Fig. 78). Measurements: AME–AME 0.10; AME–ALE 0.20; AME diameter 0.12; PME–PME 0.20; PME–PLE 0.20; PME diameter 0.12; MOQAW 0.35; MOQPW 0.45; CI (CL/CW) 1.35; LL:CL 7.52; STL 1.30; STW 1.05. Leg measurements: I—4.4+1.3+5.4+5.8+1.9 = 18.8; II—3.4+1.0+3.3+3.5+1.1 = 12.3; III—2.3+0.9+2.0+2.6+0.9 = 8.7; IV—3.4+1.0+3.2+4.0+1.2 = 12.8; palp—1.5+0.4+0.9+1.3 = 4.1. Leg spines: I 0- 1p1r-1p1r, 2v-2 v1 p1r-1p1r, 2 v1 p1r-1 v1 p1r-1 v1 p1r; II 0-1p1r-1p1r, 2v-2 v1 p1r-1p1r, 2 v1 p1r-2 v1 p1r-1 v1 p1r; III 0- 1p1r-1p1r, 1v- 1p1r-1p1r, 2 v1 p1r-1 v1 p1r-3 v1 p1r; IV 0-1p1r-1p1r, 1v- 1p1r-1p1r, 2 v1 p1r-2 v1 p1r-3 v1 p1r. Abdomen ( Fig. 60 View FIGURES 55 – 60 ): slightly more elongate than in female. Palp (Figs 79–80): cymbium elongate, about equal to tibia plus patella length, with an apophysis that points proximally, with a single point at apex; RTA with two points at apex; TA sclerotized, long and with two points at apex; EM long, almost encircling tegulum, ending at CON apex; CON unsclerotized but distinct.

Distribution. Comoros and south-western Madagascar ( Fig. 54 View FIGURES 49 – 54 ).

Habitat. Collected in forest and spiny forest/thicket.
