Cebrennus aethiopicus Simon, 1880: 334  (description of male; holotype male, Eritrea, Massaua, MNHN 1613-3274, examined). Fage 1921: 162, figs 1 d –e (illustration of male); Jäger 2000: 176, figs 49–55 (illustration of male, description of female); Jäger and Kunz 2005: 169, figs 283–291 (illustration of male and female from A [Ain/Al/As?] Sefza [Sefra/ Safra?].

Material examined. SUDAN: Red Sea: 1 male (PJ 3474), open alkaline plain, Gowb, C. Dewhurst leg. March 2001 ( RMCA 236151). ERITREA: Anseba: 1 female (PJ 3408), Gheleb, RII 12975View Materials ( SMF 9912975). Northern Red Sea: Holotype male (PJ 3441), Massaua, 1613-3274 ( MNHN); 1 female (PJ 3473), Red Sea Coast, in sand on Red Sea, C. Dewhurst leg. 9 November 1996 ( RMCA 236132). DJIBOUTI. 1 male (PJ 3442; + 1 immature), Djibouti, 1613-1944 ( MNHN).

Diagnosis. Medium-sized Sparassinae, body length of males: 10.5–11.1, females: 12.7–17.5. Copulatory organ similar to those of C. wagae  , C. castaneitarsis  and C. flagellatus  spec. nov. in having a very long embolus with distal loop as long as the tegulum or larger ( Figs 24–31View FIGURES 24 – 29View FIGURES 30 – 35. 30 – 31). Distinguished from C. flagellatus  spec. nov. by the absence of an additional flagellum at the embolus kink. In males, the RTA in retrolateral view is as long as the tibia or slightly longer, i.e. the ratio RTA/tibia ranges from 1.00 to 1.16, which is intermediate between C. castaneitarsis  and C. flagellatus  spec. nov. on the one hand and C. wagae  on the other hand. Moreover, males differ from those of the three other species by having the embolus arising in a 3 to 3.30 o’clock-position from tegulum, embolus base reaching the retrolateral margin of tegulum. Females ( Figs 55–62View FIGURES 55 – 62): Epigynal field’s ratio width/length ranges from 1.46 to 1.58, i.e. generally wider than the other Cebrennus  spp. Lateral epigynal ledges with their posterior ends closer to each other than anterior ends or as close as these. Males and females with 5 to 6 cheliceral posterior teeth ( Figs 70–75View FIGURES 63 – 76).

Description. See Jäger (2000). Additional data of PJ 3474 as following (with data, if present, of holotype in parentheses): Male. PL 5.8 (6.2), PW 5.3 (5.0), AW 3.4 (3.6), OL 4.7 (4.9), OW 3.7 (3.3).

Chelicerae with 2 anterior teeth and with 5 (6) posterior teeth. Margin of chelicerae close to fang base with 5 bristles ( Figs 73, 75View FIGURES 63 – 76).

Colouration: pale yellowish brown, without distinct pattern, but chelicerae, dorsal prosoma and opisthosoma with indistinct markings; distal appendages slightly darker.

Spination: Palp: 130, 0 0 0, 1000 (0001), 1000 (0002); legs: femur I –II 323, III 323 (2), IV 322; patella I –IV 000; tibia I 202 (1) 4, II –IV 2024; metatarsus I 2024 (3034), II 2024 (2034, median prolateral missing), III 2024 (3034), IV 3036. Ventral metatarsi I –IV with sparse scopula in distal half, without spines or bristles distally. Measurements leg I: [n= 2] 23.1–28.3 (6.6–7.8, 2.7–3.4, 5.5 –7.0, 6.5 –8.0, 1.8–2.1). Palpal claw with 8 to 9 teeth. Margin of chelicerae close to fang base with 3–5 bristles ( Figs 70 –72, 74View FIGURES 63 – 76).

Colouration: (pale) yellowish brown, without distinct pattern, dorsal opisthosoma with indistinct dots; chelicerae (light) reddish brown, distal appendages slightly darker.
