Cebrennus spec. A

Figs 14 , 173

Material examined. ALGERIA: Bechar Province: 1 male (PJ 3466), Grand Erg occidental, Beni Abbes [N 30° 8'0.01", W 2° 9'59.98", ca. 500 m elev.], Coll. Denis, December 1949 ( MNHN).

Diagnosis. Medium-sized Sparassinae, body length of male: 10.6. Male copulatory organ similar to those of C. wagae , C. flagellatus spec. nov., C. aethiopicus and C. castaneitarsis in having a very long embolus with distal loop as long as the tegulum or larger ( Fig. 14 ), but distinguished from C. flagellatus spec. nov. by the absence of an additional flagellum at the embolus kink, from C. castaneitarsis and C. flagellatus spec. nov. by its relatively long embolus (in retrolateral view the RTA is longer than the tibia length, i.e. the ratio RTA/tibia is 1.21), from C. aethiopicus distinctly and from C. wagae slightly in having the embolus arising point shifted prolaterally. Chelicerae with 2 anterior and 4 posterior teeth. Margin of chelicerae close to fang base with 3 and 5 bristles, respectively.

Description. Male: PL 5.1, PW 3.9, AW 2.8, OL 5.4, OW 3.5; AME 0.40, ALE 0.29, PME 0.25, PLE 0.26, AME–AME 0.17, AME–ALE 0.13, PME–PME 0.43, PME–PLE 0.50, AME–PME 0.30, ALE–PLE 0.45, clypeus AME 0.12, clypeus ALE 0.15. Spination: Palp: 130, 0 0 0, 1000; legs (II lacking): femur I, III 323, IV 322; patella I, III–IV 000; tibia I 2024, III 2024, IV 2023; metatarsus I, III 2024, IV 3026. Ventral metatarsi I–IV with scopula in distal half, without spines or bristles distally. Measurements leg I: 25.0 (7.2, 2.3, 6.6, 7.1, 1.8).

Colouration: pale yellowish brown, without pattern.

Note. This male specimen cannot be assigned clearly to one of the known species. Its intermediate position between C. wagae and C. castaneitarsis and the absence of sufficient data on intraspecific variability (see introduction) makes it difficult to decide whether the male possibly belongs to an own species or not. Considering its geographic distribution (1000 km SW of type locality of C. wagae , 640 km SSW of type locality C.

castaneitarsis , 760 km E of locality of the female listed below; Fig. 173 ) and considering that no other records of the species involved are known from the region around Beni Abbes, the specimen is left unidentified until more material is available.
