Cebrennus castaneitarsis Simon, 1880: 333  (description of male; male syntypes from Algeria, Oran [= Wahran], MNHN 1614- 3548, examined). Simon 1897: 38, figs 36, 38, 40 (illustration of male), Fage 1921: 162, figs 1 a –c (illustration of male); Levy 1989: 159, figs 94–99 (illustration of male and female, synonymy of C. sparassoides  ); Jäger 2000: 174, figs 42–46 (modified illustration of male and female after Fage 1921 and Levy 1989).

Cebrennus sparassoides Caporiacco, 1928: 94  , fig. 6 (description of male).

Note. In MNHN 1614 -3548, 13 males and 2 females are present. One label [extra: Casablanca, Morocco, Benoit st. VI- 18] suggests that specimens have been added later to the original specimen(s)/series as it is known from other cases (e.g., in Heteropoda javana MNHN 1677 - 290, see Jäger 2002: 45). Jäger (2000) followed Levy (1989) and assumed a holotype male. The series only now examined showed that at least some males could constitute a series of syntypes. It is not clear, whether males were added from Casablanca or not.

Material examined. ALGERIA: Oran: 13 males, 2 females (PJ 3443 –3455, 3456– 3457; among these the male syntypes), Oran ( MNHN 1614-3548; but see also note above for potential additional locality in Morocco). 1 male (PJ 3458), without further data, E. Simon det. 1883 ( MNHN).

Diagnosis. Medium-sized Sparassinae, body length of males: 12.7 ( Levy 1989: males 10.1–13.9, females 12.4–16.4). Male copulatory organ similar to those of C. wagae  , C. flagellatus  spec. nov. and C. aethiopicus  in having a very long embolus with distal loop as long as the tegulum or larger ( Figs 15–17View FIGURES 12 – 17. 12 – 13). Distinguished from C. flagellatus  spec. nov. by the absence of an additional flagellum at the embolus kink, from C. aethiopicus  and C. wagae  by the distinctly shorter RTA: in retrolateral view the RTA is shorter than the tibia length in C. castaneitarsis  , i.e. the ratio RTA/tibia ranges from 0.7 to 0.9. Males differ from those of the three other species by having the embolus arising in a 6 o’clock-position from tegulum. There were only few females available ( Figs.View FIGURES 36 – 43. 36 – 38

36–38), therefore the following data are preliminary. Epigynal field’s ratio width/length ranges from 1.35 to 1.41. Lateral epigynal ledges with their anterior ends closer to each other than posterior ends or of equal distance (as in C. wagae  ). Males with 5 to 6 posterior cheliceral teeth, females with 4 to 6 ( Levy 1989).

Description. See Levy (1989). Some additional characters are given here for 1 male (PJ 3458): PL 6.3, PW 5.2, AW 3.8, OL 6.4, OW 4.9; AME 0.42, ALE 0.30, PME 0.28, PLE 0.30, AME –AME 0.20, AME –ALE 0.25, PME –PME 0.52, PME –PLE 0.81, AME –PME 0.39, ALE –PLE 0.68, clypeus AME 0.15, clypeus ALE 0.16. Spination: Palp: 0 30, 0 0 0, 1000; legs: femur I –II 323, III 3 (2) 23, IV 332 (222); patella 000; tibia I 2024 (3), II –III 2024, IV 2024 (3); metatarsus I-III 2024, IV 3026. Ventral metatarsi I –IV with scopula in distal half, without spines or bristles distally. Measurements leg I: 30.9 (8.2, 3.0, 7.6, 8.8, 2.3). Margin of chelicerae close to fang base with 4 bristles.

Colouration: yellowish to greyish brown, without distinct pattern. Distal leg segments darker, esp. in leg I.

Distribution: Algeria to Israel ( Fig. 173View FIGURE 173).
