Distance PME-PME 0.25, diameter PME 0.10, distance PME-ALE 0.05, distance AME-AME 0.05, diameter AME 0.10. Sternum wider than long (1.05/0.88). Habitus as in Fig. 6E, F View Figure 6 . Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus yellowish; sternum brown. Legs yellowish, but dark brown on patellae and whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and proximal and subdistal parts of tibiae. Opisthosoma yellowish, with dorsal and lateral spots. Ocular area elevated, without eye stalks. Thoracic furrow absent. Chelicerae (Fig. 6D View Figure 6 ) with pair of proximo-lateral apophyses and pair of distal apophyses provided with two teeth each. Pedipalps as in Fig. 5A, B View Figure 5 ; trochanter with long, retrolaterally strongly bulged ventral apophysis; femur with indistinct ventral protuberance; tibia with prolatero-ventral projection; procursus simple proximally but complex distally, with large, prolateral membranous lamella (arrowed 1 in Fig. 5C View Figure 5 ), large, dorsal membranous lamella with sawtooth (arrowed 2 in Fig. 5C View Figure 5 ), large, angular ventral sclerite (arrowed in Fig. 5B View Figure 5 ), spine-shaped prolateral apophysis (arrowed 3 in Fig. 5C View Figure 5 ), and dorsal spine (arrowed in Fig. 5D View Figure 5 ); bulb with short curved ‘pseudo-appendix’ (arrowed in Fig. 6C View Figure 6 ); uncus with scaly edge (Fig. 6C View Figure 6 ); embolus weakly sclerotized, with some transparent distal projections (Fig. 6C View Figure 6 ). Retrolateral trichobothrium of tibia I at 5% proximally; legs with short vertical setae on tibiae, metatarsi, and tarsi, without spines or curved setae; tarsus I with 33 distinct pseudosegments.

Female (IZCAS-Ar40903): Similar to male, habitus as in Fig. 6G, H View Figure 6 . Total length 5.19 (5.38 with clypeus), carapace 1.36 long, 1.66 wide, opisthosoma 3.83 long, 1.68 wide; tibia I: 8.50; tibia I L/d: 54. Distance PME-PME 0.20, diameter PME 0.10, distance PME-ALE 0.05, distance AME-AME 0.05, diameter AME 0.08. Sternum wider than long (1.08/0.92). Clypeus brown. External female genitalia (Fig. 6A View Figure 6 ) curved posteriorly, with short knob. Vulva (Fig. 6B View Figure 6 ) with slightly curved, sclerotized anterior arch provided with median sclerite (arrowed in Fig. 6B View Figure 6 ) and pair of oval pore plates.
