Diagnosis.
C. punctipedellum
is most similar to
C. molle
L. Koch, 1875
, having a bifid DTA and a RTA in males and copulatory ducts where anterior proceeding part and posterior proceeding part lay close to each other and are of almost equal length in females. Differs by the copulatory ducts of female entering the spermathecae anteriomedially and not anterio-laterally (see
Lotz 2007a
: figs 87, 100), and males by the fangs lacking a basal knob and the TA apex being broader and the RTA’s having more rounded apexes (see
Lotz 2007a
: figs 91–92 and
Figs 35– 36
).
Description.
Females redescribed by

Male
: (n = 3): TL = 6.40 (6.0–6.7); CL = 2.93 (2.8–3.0); CW = 2.20 (2.1–2.3); OAL = 0.47 (0.45–0.50); OAW = 1.00 (1.0–1.0); CLL = 0.10 (0.1–0.1). Chelicerae: robust with long fangs, without basal knob; fang furrow with six teeth of unequal size, with PMT:RMT = 3:3 (

Leg measurements: I—4.4+1.5+4.5+5.1+1.9 = 17.4; II—3.3+1.3+3.1+3.6+1.1 = 16.4; III—2.7+1.1+2.1+2.9+0.8 = 9.6; IV—3.8+1.3+3.2+4.4+1.1 = 13.8; Palp—1.4+0.5+0.7+1.5 = 4.1. Leg spines: I 0-1p1r-1p1r,

Figs 35–36
): cymbium elongate, more than twice tibia length (excluding RTA’s), with a straight proximally directed apophysis with a sharp apex; tibia with bifid DTA and RTA; DTA short, dorso-lateral part with a sharp apex; RTA with a single apex; TA sclerotized, long, with broad apex; EM long, almost encircling tegulum, ending at CON apex; CON not sclerotized but distinct.
