Figs 32–35 , 76 , 87 , 97–100 , 173

Type material. AFGHANISTAN: Nangarhar: Holotype male (PJ 3406), 12–20 km ESE Jalalabad, Povolný & Tenora leg. 16 March 1966, #36 ( MMBC).

Diagnosis. Medium-sized Sparassinae, body length of male: 11.6. Copulatory organ ( Figs 32–35 ) similar to those of C. wagae , C. castaneitarsis and C. aethiopicus in having a very long embolus with distal loop as long as the tegulum or larger, but distinguished from these three species by the additional flagellum at the embolus kink. RTA with distinct wrinkle (W) basally and building almost a right angle with this wrinkle in ventral view.

Etymology. The specific name refers to the additional flagellum at the embolic kink (Latin “ flagellatus , -a, - um”, meaning verbatim “whipped”, in the figurative sense “equipped with a whip”); adjective.

Description. Male: PL 5.3, PW 4.5, AW 3.0, OL 6.3, OW 4.5. AME 0.41, ALE 0.31, PME 0.25, PLE 0.26, AME–AME 0.16, AME–ALE 0.15, PME–PME 0.52, PME–PLE 0.55, AME–PME 0.32, ALE–PLE 0.45, clypeus AME 0.15, clypeus ALE 0.19 ( Fig. 87 ). Spination: Palp: 130, 0 0 0, (1201; stiff setae rather than spines), 1000; legs: femur I–III 323, IV 322; patella 000; tibia I–IV 2024; metatarsus I–III 2024, IV 3036. Ventral metatarsi I–IV with sparse scopula in distal half, without spines or bristles distally. Leg formula: 2143. Measurements of palp and legs: Palp 7.7 (2.2, 1.1, 1.4, -, 3.0), leg I 25.7 (7.1, 2.5, 6.8, 7.3, 1.8), leg II 28.1 (8.1, 2.6, 7.5, 7.9, 2.0), leg III 20.8 (6.3, 2.3, 5.2, 5.5, 1.5), leg IV 25.4 (7.8, 2.4, 6.4, 7.0, 1.8). Cheliceral furrow with 2 anterior and 5 posterior teeth (3 adnate + 2 smaller single teeth), without denticles ( Fig. 76 ). Margin of chelicerae close to fang base with 3 bristles. Epiandrium with two darker sockets with each 6–10 distal setae (spigots?).

Palp as in diagnosis ( Figs 32–35 ). Distal third of cymbium with dorsal scopula. RTA with voluminous base (in retrolateral view), reaching almost middle part of tegulum, distal tip bent. Embolus arising in a 4-o’clock-position, embolic kink situated at 12-o’clock.

Colouration in ethanol ( Figs 97–100 ): Yellowish-brown with anterio-lateral margin of dorsal shield of prosoma and distal chelicerae darker. Sternum, ventral coxae, gnathocoxae, labium and ventral femora pale yellowishbrown. Palp and legs yellowish-brown with distal segments darker. Dorsal and lateral opisthosoma with elongate small patches.

Female: unknown.

Distribution. Only known from the type locality ( Fig. 173 ).
