Etymology

. The specific name is derived from the Greek word “cephalos”, meaning “head”, referring to the brown cephalic region of the females; noun in apposition.

Diagnosis

. The new species differs from congeneric species by the following combination of characters: 1) a somewhat rectangular scape; 2) a slender, translucent subterminal apophysis; 3) a tegular protuberance near the base of the median apophysis; and 4) an abdomen with an arcuate brown patch anteriorly and four transverse brown patches medially and posteriorly.

. Male (holotype, Figs 16 , 17D, E , 21C ). Total length 2.40. Carapace 1.20 long, 0.90 wide. Abdomen 1.20 long, 1.00 wide. Clypeus 0.10 high. Eye sizes and interdistances: AME 0.10, ALE 0.05, PME 0.08, PLE 0.05, AME-AME 0.08, AME-ALE 0.05, PME-PME 0.03, PME-PLE 0.08, MOA length 0.23, anterior width 0.25, posterior width 0.20. Leg measurements: I 3.90 (1.20, 1.25, 1.00, 0.45), II 3.30 (1.00, 1.00, 0.90, 0.40), III 2.20 (0.70, 0.70, 0.50, 0.30), IV 3.40 (1.05, 1.05, 0.90, 0.40). Carapace pear shaped, dark brown, cervical groove inconspicuous, fovea longitudinal. Chelicerae dark brown, four promarginal teeth, two retromarginal teeth. Endites and labium dark brown, paler distally. Sternum dark brown with indistinct, darker radial patches. Legs yellow without annulations, femur II with a furrow basally, tibia II with seven macrosetae. Abdomen elliptical, about 1.2 times longer than wide, dorsum yellow with arcuate brown patch anteriorly, four transverse brown patches medially and posteriorly; venter grayish yellow laterally, brown medially. Spinnerets grayish yellow.

Palp (Figs 16 , 21C ): with one patellar bristle; tegulum with a protuberance near base of median apophysis (see arrow in Fig. 16A ); median apophysis hooked; embolus thick, slightly curved; conductor membranous, as long as embolus in prolateral view; terminal apophysis prominent, pointed distally; subterminal apophysis slender, translucent.

Female (paratype IZCAS-Ar42559, Figs 17A-C, F, G ). Total length 2.45. Carapace 1.10 long, 0.85 wide. Abdomen 1.60 long, 1.10 wide. Clypeus 0.03 high.
