( Figs. 7–8 ) Description. FEMALE ( holotype ). Gnatosoma inserted terminally. Cheliceral base 90 long, cheliceral shaft 115 long. Fixed cheliceral digit 15 long, with numerous apical tines. Movable cheliceral digit with basal spur. Palpal femur and genu with smooth setae, 60 and 65 long, respectively. Palpal tibia with 3 smooth setae and short claw, palpal tarsi with 3 smooth setae ( Fig. 8 A–B). Subcapitulum with filiform setae n , 25 long. Free lateral part of peritremal branch 40 long. Hypostome 170 long, with smooth rounded apex. Idiosoma 410 long and 945 wide. FIGURE 7. Pterygosoma olape sp. nov. , female. A , dorsal view; B , ventral view. Dorsum ( Fig. 7 A) with 3 groupings of setae: 27 pairs of antero-lateral plumose setae, 15–20 long; 2 pairs of dorsomedian setae, 35 long: dm1 serrated, dm2 paddle-shaped with spicules on apical part and with 4 pairs of posterolateral paddle-shaped setae with minute spicules on apical part, 40–70 long. Eyes absent. Venter ( Fig. 7 B) with 3 pairs of ventro-median setae: vm1 filiform, vm2–vm3 slightly serrated. Peripheral series represented by 3 pairs of paddle–shaped setae with spicules on apical margin, 95–155 long, situated laterally and 13 pairs of setae of 2 types : tapered or apically expanded, 280–385 long, located on posterior part of idiosoma. Genital slit situated ventrally. Genital series represented by 1 pair of spin-like setae g1 . Pseudoanal setal series represented by 4 pairs of paddleshaped setae, ps1–2 situated ventrally, about 190 long, ps3–4 situated dorsally, 125–140 long. Legs. Coxal setation: 1a , 1b , 2b , 3a , 3b arranged in formula 2–1–2–0, all setae filiform; setae of trochanters I–IV (1–1–1–1), femora I– IV (3–1–1–1), genua I–IV (2–0–0–1), tibiae I–IV (5–3–3–3). All setae on each prodomers filiform, except for plumose setae d’FI and l’FII–FIV. Setation of tarsi: I 13 setae ( ft , tc’ , tc” , p’ , p” , a’ , a” , it’ , it” , u’ , u” , vs’ , vs” ) and solendion ω1 ; II 8 setae ( tc’ , p’ , p” , it’ , it” , u’ , u” , vs’ ) and ω1 ; III and IV with 8 setae each ( tc’ , p’ , p” , it’ , it” , u’ , u” , vs’ ). Setae tc’ , tc” , a’ , a” of leg I represented by euphatidia, p’ and p” fan-like. Setae tc’ of legs II–IV and it’ , it” , u’ , u” , vs’, vs” of legs I–IV smooth. FIGURE 8.

Holotype female from Agama sankaranica (ZMUC R36473) [dorsal surface] NIGERIA : Ondo State, Idanre; 18–21 August 1958 , coll. Schiøtz and Volsøe. Type material deposition. Holotype is deposited in the ZMUC (ZMUC–R36473). Etymology. This new species is dedicated to the mythological Maasai God of the Sun. Differential diagnosis: P. olape sp. nov. is similar to P. engai sp. nov . In females of both species, the cheliceral shaft is 1.3 longer than the base, setae n , dF , and dG are subequal in the length, the free peritremal branches are present and are approximately the same length, the eyes are absent, ventro-median setae vm1 are filiform, setae ps are paddle-shaped with spicules on the apical margin. This new species differs from P. engai by the presence of the hypostome with a smooth rounded apex, there are 16 pairs of the peripheral setae inserted ventrally, the genital series is represented by one pair of setae g situated ventrally, the pseudoanal series is represented by four pairs of setae ps situated ventrally and terminally. In females of P. engai , small denticles at the hypostomal apex are present, the peripheral setae are absent, the genital series is represented by three pairs of setae g situated dorsally, the pseudoanal setal series is represented by three pairs of setae ps and all of them are situated dorsally.
