description: Sadala rufa (Keyserling, 1880) comb. rest.
Figs 56–61, 90
Sparassus rufus Keyserling, 1880: 263, plate 7, fig. 145 (Female holotype from Bogota [4.6492, ‑74.0628], Bogota, Colombia, NHM 1890.7.1.3138, examined); Simon 1897: 35.
Sadala rufa: Simon 1880: 318.
Olios rufus: Simon 1903a: 1020; Petrunkevitch 1911: 502; Jäger 2020: 94, figs 341–348 (misplaced in Olios).
Olios corallinus Schmidt, 1971: 390, fig. 2 (holotype female, 2 female paratypes assumingly from Ecuador, introduced to Germany: Hamburg, Lübeck, Mainz, depository uncertain, not examined). Jäger 2020: 81, figs 273–280 (misplaced in Olios). syn. nov.
Note. The location of the types of O. corallinus is uncertain. Jäger (2020) illustrated an epigyne of what he believes might be a paratype, mounted on a glass slide, deposited in Senckenberg Research Institute (SMF 25776), which is in accordance to that depicted by Schmidt (1971). Based on these illustrations, this species is here considered a junior synonym of S. rufa (Keyserling).

Diagnosis. Males of S. rufa resemble those of S. keyserlingi (Figs 24–26) and S. velox (Figs 72–74) by the palp with embolus, arising from tegulum at 6 o’clock position (Fig. 57). They are distinguished from both species by the cymbium lacking hook-shaped dorsal proximal projection (Fig. 58) and conductor base extending from central tegulum to embolus base (Fig. 57) (cymbium with hook-shaped dorsal proximal projection and conductor base not extending to embolus base in S. keyserlingi and S. velox). Females are distinguished from the remaining congeners by the epigyne with TP short, more than 7 times wider than long and arising anteriorly from MS (roughly as wide as wide as long or longer than wide and arising medially or posteriorly from MS in other species) (Fig. 59).
Description. Male (MCZ 69149): Total length 11.5. Prosoma: 5.5 long, 5.0 wide. Opisthosoma: 6.1 long, 3.6 wide. Eyes: diameters: 0.40, 0.34, 0.30, 0.34; interdistances: 0.28, 0.10, 0.50, 0.42, 0.22, 0.20. Legs: I: 31.9 (8.6, 2.8, 8.8, 9.3, 2.4): II: 34.7 (9.3, 3.1, 9.7, 9.7, 2.4); III: 23.4 (7.0, 2.4, 6.1, 6.1, 1.8); IV: 26.7 (8.0, 2.2, 7.1, 7.4, 2.0). Spination follows the generic pattern except patella III: p0. Palp: RTA two times longer than wide, finger-like, pointing antero-ventrad in retrolateral view; PTA triangular, as long as wide; subtegulum visible prolaterally in ventral view; tegulum oval; conductor more than five times longer than wide, anteriorly fanned (Figs 56–58).
Redescription. Female (MCZ 69333): total length 20.8. Prosoma: 8.8 long, 8.1 wide. Opisthosoma 11.7 long, 7.3 wide. Eyes: diameters: 0.60, 0.46, 0.34, 0.48; interdistances: 0.48, 0.30, 0.78, 0.70, 0.50, 0.36. Legs: I: 37.1 (10.5, 4.5, 9.9, 10.0, 2.2); II: 39.3 (11.3, 4.5, 10.5, 10.7, 2.3); III: 29.3 (9.1, 3.7, 7.4, 7.0, 2.1); IV: 32.0 (9.8, 3.5, 7.9, 8.6, 2.2). Spination follows the generic pattern. Epigyne: EF slightly wider than long with transversal anterior groove; MAB embedded in EF; MS rectangular, wider than long; LL touching posteriorly; (Fig. 67). Vulva: FW postero-mediad; GP short, rounded, arising from ducts at second turn; SP elongate; FD laterad (Figs 60–61).
Variation. Males (n = 9): total length 11.2–12.9; prosoma length 4.9–5.7; femur I length 8.2–9.9. Females (n = 9): total length 18.1–22.8; prosoma length 8.0–9.2; femur I length 8.3–10.7.
Distribution. Panama and northwestern South America (Colombia and possibly Ecuador) (Fig. 90).
