Diagnosis: Males differ from those of C. concolor by the morphology of the tibial apophysis ( Figs. 13– 14 ) and palpal bulb ( Figs. 15–17 ) and from those of C. olivaceum by the retrolateral branch of tibial apophysis being narrower, shorter and bearing 10 spines or fewer ( Figs. 13–14 ). Females are distinguished by spermathecal morphology which comprise two very long, thin receptacula surmounted by a single terminal lobe ( Fig. 18 ).

Description: Male (holotype, NMW 18253). Total length 11.4. Carapace length 5.1, width 4.4. Eye tubercle length 0.6, width 0.8; anterior row procurved, posterior recurved, clypeus absent. Labium length 0.6, width 1.0. Sternum length 2.5, width 1.4. Chelicerae with 9 teeth of similar size on promargin. Labium as wide as long with 27 cuspules. Maxillae with ca. 80 cuspules on inner angle. Sternum oval, slightly longer than wide. Fovea transverse. Palp: femur 2.9/ patella 1.8/ tibia 2.3/ cymbium 0.9/ total 7.9. Legs I: femur 4.3/ patella 2.8/ tibia 3.4/ metatarsus 2.6/ tarsus 1.8/ total 14.9. II: 3.9/ 2.4/ 2.7/ 2.5/ 1.8/ 13.3. III: 3.4/ 1.9/ 2.2/ 2.8/ 1.8/ 12.1. IV: 4.5/ 2.3/ 3.6/ 4.1/ 2.3/ 16.8. Spines. Palp: tibia (p) 0–2–1. Legs: I: tibia (v) 1–2–1, (p) 0–0– 1, metatarsus (v) 0–0–ap 1. II: tibia (v) 2–1–ap3, (p) 0–0–1, metatarsus (v) 0–2–ap1, (p) 0–1–0.

Palpal bulb with long, thin embolus, inserted proximaly on tegulum ( Figs. 15–17 ). Tibial apophysis ( Figs. 13–14 ) comprising two branches: prolateral branch short with adjacent spine; retrolateral branch slightly curved, distal and proximal portion same width. Metatarsus I slightly curved, bends over retrolateral branch. Metatarsal scopulae extent (ventral surfaces only): I on distal three-quarters; II on slightly more than distal half; III on distal half; IV on distal third. Tarsal scopulae (ventral surfaces only): I–IV divided by longitudinal band of thick setae.

Female (paratype, NMW 18254). Total length 23.5. Carapace length 8.0, width 6.4. Eye tubercle length 0.9, width 1.3; anterior row procurved, posterior recurved, clypeus absent. Labium length 1.0, width 1.8. Sternum length 3.8, width 3.3. Chelicerae with 10 teeth of similar size on promargin. Labium as wide as long with ca.40 cuspules. Maxillae with ca.100 cuspules on inner angle. Sternum oval, slightly longer than wide. Fovea transverse. Palp: femur 4.2/ patella 2.6/ tibia 2.4/ tarsus 2.2/ total 11.4. Legs I: femur 5.5/ patella 3.7/ tibia 3.7/ metatarsus 2.8/ tarsus 2.0/ total 17.7. II: 4.7/ 3.2/ 2.9/ 2.5/ 1.8/ 15.1. III: 4.2/ 2.6/ 2.1/ 2.9/ 1.7/ 13.5. IV: 5.5/ 3.2/ 3.8/ 4.2/ 2.1/ 18.8. Spines.

IV: tibia (v) 2–2–ap2, (r) 1–1–0, metatarsus (v) 2–1–ap3, (p) 0–1–1, (r) 0–1–1. Spermathecae comprising two straight receptacula with single apical termini ( Fig. 18 ). Metatarsal scopulae extent (ventral surfaces only): I–II along entire length; III on slightly more than distal half; IV on slightly less than distal half. Tarsal scopulae (ventral surfaces only): I–IV divided by longitudinal band of thick setae.

Distribution: Known only from Cyprus.

Ecology: Spiders were found in gardens under rocks, logs and leaf litter where they construct a silk-lined tubular burrow. C. karlamani occurs sympatrically with C. olivaceum in Cyprus (V. von Wirth pers. comm.). Males are mature from January to March.
