Diagnosis. Differs from C. kioloa   as follows: palpal RVTA with short stalk; RDTA a thick, undulate spine-like process; MA with lateral process largest & weakly sclerotized. Epigynal septum not widened at middle; paired fossae with lateral extensions often longer than in C. kioloa   (“dumbbellshaped”).

Description

Male (holotype). BL 5.83, CL 2.50 (male range 2.25–3.17), CW 1.92, CapW 0.94, EGW 0.71, LL 0.31, LW 0.39, SL 1.22, SW 1.06. Legs: 1423 (I: 11.08; II: 8.67; III: 7.50; IV: 9.75); ratio tibia I length:CW = 1:0.66. Male palp ( Fig. 7a,b View Fig ). RVTA like C. kioloa   but with shorter, wider stalk; RDTA a thick, undulate, spine-like process. Distal loop of sperm duct V-shaped with limbs. Embolus longer and thinner than in C. kioloa   , and conductor apex less strongly “crested”. MA lateral process usually weakly sclerotized and larger than in C. kioloa   .

Female (KS75360). BL 6.08, CL 2.58 (female range 2.42–3.25), CW 1.67, CapW 1.14, EGW 0.75, LL 0.35, LW 0.41, SL 1.31, SW 1.10. Legs: 1423 (I: 9.10; II: 7.27; III: 6.41; IV: 8.24); ratio tibia I length:CW = 1:0.72. Epigynum ( Fig. 7c–e View Fig ). Median septum relatively narrower than in C. kioloa   and not obviously widened at middle. Paired fossae often with longer lateral extensions and more obviously narrowed centrally (more or less “dumbbell-shaped”, cf. C. kioloa   ). Internal genitalia similar to C. kioloa   .

Distribution. Central eastern New South Wales to southeast Queensland.

Etymology. The species name is taken from the type locality.
