Etymology.
The name is a patronym in honour of the late Vince Roth, one of the collectors of the
holotype
.

Diagnosis.
C. rothi
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. fisheri
sp. nov.
and
C. griswoldi
sp. nov.
in the dumbbell-shaped spermathecae and U-shaped CA. In females of
C. rothi
sp. nov.
the anterior sphere of the spermathecae is noticeably smaller than the posterior one, separating it from the other species mentioned above (
Fig. 109
). In males of
C. rothi
sp. nov.
and
C. ambrense
sp. nov.
the CA is relatively short compared to that of the other species in the group.
C. rothi
sp. nov.
is differentiated from
C. ambrense
sp. nov.
by the CA narrowing gradually towards the apex (
Figs 111–112
). Furthermore in
C. rothi
sp. nov.
and
C. ashleyi
sp. nov.
the RTA ends in three points (
Figs 41
and
111
).
Description.
Female
: (n = 10): TL = 5.12 (3.4–6.2); CL = 2.10 (1.5–2.5); CW = 1.50 (1.1–1.7); OAL = 0.30 (0.25–0.35); OAW = 0.93 (0.70–1.05); CLL = 0.05 (0.05–0.05). Chelicerae: robust with long fangs; cheliceral fang furrow with nine teeth of unequal size, PMT:RMT = 3:6 (
Fig. 107
). Measurements: AME–AME 0.15; AME–ALE 0.25; AME diameter 0.10; PME–PME 0.20; PME–PLE 0.25; PME diameter 0.10; MOQAW 0.40; MOQPW 0.45; CI (CL/CW) 1.44; LL:CL 5.76; STL 1.2; STW 0.9. Leg measurements: I—3.5+0.9+3.8+4.0+1.9 = 14.1; II—2.1+0.8+1.9+2.2+0.8 = 7.8; III—1.5+0.7+1.1+1.6+0.7 = 5.6; IV—2.3+0.8+2.3+2.6+0.8 = 8.8; palp—1.1+0.4+0.8+0.9 = 3.2. Leg spines: I 0-1p-1p1r,

p1r. Abdomen (
Fig. 99
): creamy-grey with a heartmark bordered in white. Epigynum (
Figs 108–109
): wider than long, with two depressions separated by a septum; copulatory openings situated in anterior edge of depressions; internally, copulatory ducts proceed anterolaterally, curving medially and posteriorly before ending anterio-medially in the dumbbell-shaped spermathecae; fertilization ducts exit spermathecae posteromedially.
Male
: (n = 10): TL = 6.69 (5.2–8.2); CL = 2.65 (2.2–3.2); CW = 1.83 (1.5–2.1); OAL = 0.34 (0.30–0.40); OAW = 1.11 (0.85–1.45); CLL = 0.10 (0.08–0.10). Chelicerae: similar to female, except with PMT:RMT = 3:5–7 (
Fig. 110
). Measurements: AME–AME 0.10; AME–ALE 0.20; AME diameter 0.10; PME–PME 0.20; PME–PLE 0.20; PME diameter 0.10; MOQAW 0.30; MOQPW 0.40; CI (CL/CW) 1.33; LL:CL 8.54; STL 1.1; STW 1.0.

p1r. Abdomen (
Fig. 100
): similar to female, but slightly more elongate. Palp (
Figs 111–112
): cymbium elongate, about equal to tibia plus patella length, with a distally curled apophysis, without flattened extensions before apex; RTA with three-pointed apex, one point hooked and other two points only visible at a certain angle; TA unsclerotized, long and bent at apex; EM long, almost encircling tegulum, ending at CON apex; CON unsclerotised but distinct.
Distribution.
Known from several localities, mostly on the eastern side of
Madagascar
(
Fig. 118
).
Habitat.
Forests, including rainforest, dry forest and dwarf littoral forest.
