Figs 101–108View FIGURES 101 – 104View FIGURES 105 – 108, 173View FIGURE 173

Type material. CANARY ISLANDS. Holotype male (PJ 3404), labelled “ 71.I.d” ( MNHN). Paratype: 1 male (PJ 3405), labelled “ 71.1 a, T 71 - 1 ” ( SMF).

Diagnosis. Medium-sized Sparassinae, body length of female: 12.8. Copulatory organ similar to those of C. villosus  and C. concolor  in having the distal part of the embolus coiled in a circle, but distinguished by 1. distal coil of embolus situated at distal tegulum (retrolaterally in C. villosus  and C. concolor  ), 2. RTA distinctly longer than in C. villosus  and C. concolor  (shorter or almost absent in C. villosus  and C. concolor  ), 3. embolus arising in a 6 - o’clock-position (8 - to 9 -o’clock-position in C. villosus  and C. concolor  ) ( Figs. 105–106View FIGURES 105 – 108).

Etymology. The species is dedicated to my beloved daughter Laura Schwalbach; noun (name) in genitive case.

Description. Female (holotype): PL 6.4, PW 5.3, AW 4.0, OL 6.5, OW 4.5. AME 0.39, ALE 0.31, PME 0.25, PLE 0.28, AME –AME 0.31, AME –ALE 0.35, PME –PME 0.48, PME –PLE 1.04, AME –PME 0.43, ALE –PLE 0.82, clypeus AME 0.27, clypeus ALE 0.23 ( Fig. 108View FIGURES 105 – 108). Spination: Palp: 0 20, 0 0 0, 1000; legs: femur I 223 (324), II 3 (4) 23, III 322 (1), IV 321; patella 000; tibia 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 7.0 (2.4, 0.9, 1.1, -, 2.6), leg I 24.0 (6.7, 2.6, 6.2, 6.6, 1.9), leg II 26.6 (7.4, 2.7, 7.1, 7.3, 2.1), leg III 19.2 (5.8, 2.3, 4.9, 4.7, 1.7), leg IV 23.2 (7.1, 2.4, 5.8, 6.2, 1.7). Cheliceral furrow with 2 anterior and 6 adnate posterior teeth, without denticles ( Fig. 107View FIGURES 105 – 108). Margin of chelicerae close to fang base with 2 bristles.

Palp as in diagnosis ( Figs 105–106View FIGURES 105 – 108). RTA similarly long as in C. intermedius  , but disto-retrolaterad (distad in C. intermedius  ). Distal cymbium with intermediate shape between C. villosus  (blunt) and C. concolor  (pointed). Distal half of cymbium with dorsal scopula. Distal coil of embolus partly hidden behind bulging tegulum.

Colouration in ethanol ( Figs 101–104View FIGURES 101 – 104): Yellowish- to reddish-brown. Dorsal prosoma yellowish-brown with anterio-lateral margin darker. Sternum, ventral coxae and femora pale yellowish-brown. Gnathocoxae and labium reddish-brown with light yellowish-brown distal lip. Chelicerae deep reddish-brown with distal margins black. Palp and legs yellowish-brown with distal segments darker. Opisthosoma uniformly yellowish-brown.

Female: unknown.

Variation. Paratype with PL 5.8, PW 5.0, AW 3.6, OL 5.7, OW 5.0. Dorsal opisthosoma with median row of indistinct patches.

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