Etymology. The name is a noun in apposition of the type locality.

Diagnosis. C. anjozorobe sp. nov. is similar to C. ampijoroa sp. nov., C. andranomay sp. nov., C. ambrense sp. nov., C. ashleyi sp. nov., C. fisheri sp. nov., C. griswoldi sp. nov. and C. rothi sp. nov. in the dumbbell-shaped spermathecae and the U-shaped CA. C. anjozorobe sp. nov. females are differentiated by the copulatory ducts entering the spermathecae more posteriorly than in C. ambrense sp. nov., the morphologically closest species (compare Figs 9 and 33 ). The males of C. anjozorobe sp. nov. are differentiated by the CA ending with a flattened expansion(s) near the apex and these expansion(s) can be variable and on one or both sides of the main shaft ( Figs 35–36 ).

Description. Female: (n = 10): TL = 6.81 (4.6–9.5); CL = 2.84 (2.1–4.0); CW = 2.07 (1.5–2.8); OAL = 0.39 (0.30–0.45); OAW = 1.25 (0.95–1.65); CLL = 0.08 (0.05–0.10). Chelicerae: robust with long fangs; cheliceral fang furrow with eight or nine teeth of unequal size, PMT:RMT = 3:5–6 ( Fig. 31 ). Measurements: AME–AME 0.25; AME–ALE 0.35; AME diameter 0.15; PME–PME 0.35; PME–PLE 0.35; PME diameter 0.15; MOQAW 0.60; MOQPW 0.40; CI (CL/CW) 1.32; LL:CL 5.61; STL 1.7; STW 1.3. Leg measurements (leg formula can be 1:4:2:3 or 1:2:4:3): I—4.7+1.5+5.0+5.4+1.9 = 18.5; II—3.1+1.2+3.0+3.3+1.1 = 11.7; III—2.3+1.0+1.8+2.3+0.8 = 8.2; IV—3.3+1.2+3.0+3.5+1.1 = 12.1; palp—1.7+0.6+1.1+1.3 = 4.7. Leg spines: I 0-1p-1p, 2v-2v- 1p, 2 v1 p1r-2 v2 p1r- 1 v1 p1r; II 0-1p-1p, 0- 2 v-1p, 2 v1 p1r-2 v1 p1r-3 v1 p1r; III 0-1p1r-1p1r, 0-1p1r-0, 1 v1 r-2 v1 p1r-3 v1 p1r; IV 0-0-1p1r, 0-1 v1 r-0, 2 v1 p1r-2 v1 p1r-3 v1 p1r. Abdomen ( Fig. 25 ): creamy-yellow without distinct heartmark. Epigynum ( Figs 32–33 ): wider than long, with two depressions separated by a septum; copulatory openings in posterior-medial edge of depressions under a slight lip; internally, copulatory ducts proceed anterio-laterally, curving posteriorly before ending in medio-posterior part of dumbbell-shaped spermathecae; fertilization ducts exit spermathecae posteromedially.

Male: (n = 10): TL = 6.59 (5.4–7.5); CL = 2.79 (2.3–3.4); CW = 1.97 (1.5–2.5); OAL = 0.40 (0.30–0.50); OAW = 1.18 (0.90–1.40); CLL = 0.09 (0.05–0.10). Chelicerae: similar to female, except with PMT:RMT = 3:6 ( Fig. 34 ). Measurements: AME–AME 0.10; AME–ALE 0.30; AME diameter 0.20; PME–PME 0.30; PME–PLE 0.35; PME diameter 0.15; MOQAW 0.50; MOQPW 0.60; CI (CL/CW) 1.32; LL:CL 9.91; STL 1.8; STW 1.3. Leg measurements (leg formula can be 1:4:2:3 or 1:2:4:3): I—7.6+1.5+9.0+10.0+3.6 = 32.7; II—5.2+1.2+5.6+6.1+1.9 = 20.0; III—3.3+1.0+2.8+3.9+1.2 = 12.2; IV—5.2+1.2+5.0+6.2+1.6 = 19.2; palp—3.0+0.7+1.8+1.4 = 6.9. Leg spines: I 0-1p-1p, 2v-2v, 2v- 2v-1v; II 0-1p-1p, 0- 2 v-1p, 2v-2 v2 p2r-3 v1 p1r; III 0-1p1r-1p1r, 0-0-1p1r, 2v-2 v1 p1r- 3 v1 p1r; IV 0-1r-1p1r, 0-0-1r, 2 v1 r-2 v1 p1r-3 v1 p1r. Abdomen ( Fig. 26 ): similar to female, but a bit more elongate. Palp ( Figs 35–36 ): cymbium elongate, shorter to about equal tibia length, with a long, distally curled apophysis with a flattened extension before the apex (there is some variation in the structure of the CA); RTA broad, ending with a beaked apex; TA unsclerotized, long and bent at apex; EM long, almost encircling tegulum, ending at CON apex; CON unsclerotised but distinct.

Distribution. Several localities throughout Madagascar ( Fig. 23 ).

Habitat. Dwarf littoral forest to high altitude rainforest, including tropical dry forest and gallery forest.
