Etymology. The name is a patronym in honour of Brian Fisher, one of the collectors of the holotype.
Diagnosis. C. fisheri sp. nov. is similar to C. ampijoroa sp. nov., C. andranomay sp. nov., C. ambrense sp. nov., C. anjozorobe sp. nov., C. ashleyi sp. nov., C. griswoldi sp. nov. and C. rothi sp. nov. in the dumbbell-shaped spermathecae and the U-shaped CA. In C. fisheri sp. nov. and C. griswoldi sp. nov. females the copulatory ducts proceed not just anteriorly, but first posteriorly and then anteriorly. C. fisheri sp. nov. is separated from C. griswoldi sp. nov. by the copulatory ducts being shorter (compare Figs 45 View FIGURES 43 – 48 and 69). C. fisheri sp. nov. males are differentiated by the RTA ending in two points (compare Figs 41–42, 47–48 View FIGURES 43 – 48 , 111–112). C. fisheri sp. nov. is also a larger species than C. ashleyi sp. nov. and C. rothi sp. nov.
.
Description. Female: (n = 6): TL = 11.63 (10.7–12.2); CL = 5.12 (4.7–5.6); CW = 3.62 (3.2–4.0); OAL = 0.63 (0.60–0.70); OAW = 2.28 (2.1–2.5); CLL = 0.16 (0.15–0.20). Chelicerae: robust with long fangs; cheliceral fang furrow with six teeth of unequal size, PMT:RMT = 3:3 ( Fig. 43 View FIGURES 43 – 48 ).

Leg measurements: I—8.1+2.4+9.0+9.4+3.2 = 32.1; II—5.3+2.0+5.0+5.5+1.4 = 19.2; III—3.8+1.5+3.0+4.0+1.2 = 13.5; IV—5.5+2.0+5.0+6.0+1.4 = 19.9; palp—2.9+0.9+1.9+2.0 = 7.7. Leg spines: I 0-1p-1p, 2v-2v- 0, 2v- 2v-1v; II 0-1p-1p, 0- 2 v-0, 2 v1 p- 2v-1v; III 0- 1p1r-1p1r, 0-1p, 2v-2 v1 p1r-3 v1 p1r; IV 0-1p-1p1r, 0-1r, 2v-2 v1 p1r-3 v1 p1r. Abdomen ( Fig. 29 View FIGURES 25 – 30 ): reddish-yellow with a faint heartmark. Epigynum ( Figs 44–45 View FIGURES 43 – 48 ): wider than long with two depressions separated by a septum; copulatory openings situated medially in the depressions; internally, copulatory ducts proceed anterio-laterally, curving posteriorly before turning anteromedially to end medially in the dumbbell-shaped spermathecae; fertilization ducts exit spermathecae posteriomedially.
Male: (n = 5): TL = 10.32 (8.5–12.1); CL = 4.78 (3.6–5.9); CW = 3.36 (2.3–3.8); OAL = 0.59 (0.45–0.70); OAW = 2.02 (1.5–2.3); CLL = 0.17 (0.10–0.20). Chelicerae: similar to female, except more robust, with PMT:RMT = 3:3 ( Fig. 46 View FIGURES 43 – 48 ). Measurements: AME–AME 0.20; AME–ALE 0.45; AME diameter 0.25; PME–PME 0.40; PME–PLE 0.50; PME diameter 0.20; MOQAW 0.70; MOQPW 0.80; CI (CL/CW) 1.31; LL:CL 7.57; STL 2.5; STW 1.7. Leg measurements: I—8.5+2.3+10.2+10.3+3.5 = 34.8; II—5.7+1.9+5.7+5.8+1.5 = 20.6; III—4.2+1.5+3.4+4.4+1.2 = 14.7; IV—5.9+1.9+5.5+6.4+1.5 = 21.2; palp—3.4+0.9+1.8+1.7 = 7.8. Leg spines: I 0-1p-1p, 2v-2v- 0, 2v- 2v-1v; II 0-1p-1p, v- 2v- 1p, 0-3 v1 p- 1v; III 0-1p1r-1p1r, 0-1p1r-0, 2v-2 v1 p1r-3 v1 p1r; IV 0- 1p1r-1p1r, 0-1r-0, 2v-2 v1 p1r-3 v1 p1r. Abdomen ( Fig. 30 View FIGURES 25 – 30 ): similar in colour to female, but slightly more elongate. Palp ( Figs 47–48 View FIGURES 43 – 48 ): cymbium elongate, longer than or nearly equal to tibia length, with a long, proximally curled apophysis without flattened extensions before the apex; RTA ending with beaked point at apex; TA unsclerotized, long and bent at apex; EM long, almost encircling tegulum, ending at CON apex; CON unsclerotised but distinct.
Distribution. Several localities both from northern and southern parts of Madagascar ( Fig. 49 View FIGURES 49 – 54 ).
Habitat. Forests, including littoral rainforest, dry tropical forest and gallery forest.
