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.

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.

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.

Madagascar
(
Fig. 23
