Cebrennus

Jäger, Peter, 2014, Cebrennus Simon, 1880 (Araneae: Sparassidae): a revisionary up-date with the description of four new species and an updated identification key for all species, Zootaxa 3790 (2), pp. 319-356 : 327

Cebrennus spec. B

Figs 39–41 , 63 , 173

Material examined. MOROCCO: Guelmim-Es Semara: 1 female (PJ 3467), Aouinet Torkoz [N 28°29'10.97", W 9°51'16.11", ca. 300 m elev.], 27 December 1969, Yves Vial leg., MP 62 (A) ( MNHN).

Diagnosis. Medium-sized Sparassinae, body length of female: 18.1. Female copulatory organ similar to those of C. wagae , C. flagellatus spec. nov., C. aethiopicus and C. castaneitarsis in having two moderately bend lateral ledges, a strongly sclerotised part of the copulatory duct plus a membranous (functionally posterior) part including a pair of blind ending tubes with glandular tissue attached to the apical end ( Figs 39–41 ). The lateral slits at ledges are relatively wide in comparison to those of females of other species. From the similarity of the sclerotised part of the internal duct system with that of C. aethiopicus , it might belong to this species. However, the locality of the present female is far away from the otherwise continuous range of that species. Chelicerae with 2 anterior and 5 posterior teeth ( Fig. 63 ). Margin of chelicerae close to fang base with 6 bristles.

Description. Female: PL 6.4, PW 5.6, AW 4.3, OL 11.7, OW 10.6; AME 0.41, ALE 0.31, PME 0.30, PLE 0.32, AME–AME 0.29, AME–ALE 0.31, PME–PME 0.60, PME–PLE 0.94, AME–PME 0.39, ALE–PLE 0.82, clypeus AME 0.20, clypeus ALE 0.20. Spination: Palp: 130, 0 0 0, 1000, 1011; legs: femur I–III 323, IV 321; patella I–IV 000; tibia I–IV 2024; metatarsus I–II 2024, III 2024 (3), IV 3036(5). Ventral metatarsi I–IV with scopula in distal half, without spines or bristles distally. Measurements leg I: 23.0 (6.5, 2.8, 5.9, 6.2, 1.6). Palpal claw with 7 to 8 teeth.

Colouration: pale yellowish brown, without pattern; distal appendages slightly darker.

Note. It cannot be stated whether this female belongs to one of the described species or represents a species on its own. Neither cheliceral dentition nor the ratio of epigynal width and length can help in this respect. The same is true —by the current state of the knowledge— for the female copulatory organ.
