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).

p1r. Abdomen (
Fig. 59
): 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.
