Etymology.
The specific epithet is bestowed upon the Chilean entomologist Raúl Briones Parra, widely recognized by his nickname “ Goro ”, in recognition to his significant contributions to the field of entomology and his unwavering dedication to the conservation of the Chilean forests. A noun in apposition.
Diagnosis.
This species can be easily distinguished from the other species in the genus by having two sharp tubercles on the ventral-proximal region of the pedipalp femora. The male genitalia has a pair of ventrally curved capsula externa processes.
Distribution.
Chile: Regions of Bío-Bío, Araucanía, Los Ríos, Los Lagos.

Trochanter length 0.25, femora length 0.94, patella length 0.60, tibia length 0.70, tarsus length 0.68. Leg I: trochanter (tr) 0.27, femora (fe) 1.37, patella (pa) 0.59, tibia (ti) 0.90, metatarsus (mt) 1.13, tarsus (ta) 0.83. II: tr 0.28, fe 1.75, pa 0.79, ti 1.30, mt 1.50, ta 1.73.

Dorsum (Fig. 104 View Figure 104 , 105 View Figure 105 ). Eta (η) hourglass-shaped dorsal scutum. Ocularium low and rounded. Dorsal scutum microgranulate, with mesotergal areas that lack distinct demarcation but with small setiferous tubercles. Additionally, the mesotergal areas, posterior edge, and free tergites feature a row of small setiferous tubercles.
Chelicerae (Fig. 106 A, B View Figure 106 ). Segment I with an acute tubercle on the dorso-distal surface. Segment II bearing scattered setae in ectal and ventral views, with one triangular tubercle prominent from the others in front view.
Pedipalps (Fig. 106 C, D View Figure 106 ). Trochanter with a small dorsal and ventral tubercle. Femora bearing three dorsoproximal setiferous tubercles; 4–6 small ventral-distal tubercles and two ventral-proximal spines. Patella with 2–3 small ventral tubercles. Tibia possesses two prominent ventral-mesal spines, in addition to small sparse setiferous tubercles. Tarsus with three mesal and ectal spines in addition to setae and sparse setae.
Legs (Fig. 107 View Figure 107 ). Coxa I with 10 setiferous tubercles, II with 18–20 setiferous tubercles, III with three. Spiracles not obstructed by bridges. Smooth surface occupying 1 / 3 of leg II, ¾ of III and <1 / 3 of IV. Smooth area of leg II with 3 tubercles with subdistal setae on each side. Sternum arrow-shaped. Legs covered in small tubercles, astragalus longer than calcaneus on all legs. Tarsal count: 4–8 – 4 – 4.
Penis (Figs 108 View Figure 108 , 109 View Figure 109 ). Pars distalis characterized by a ventral plate divided into two halves by a small cleft. Each half of the plate bears three pointed macrosetae on the ventral surface and one small macroseta on the dorsal surface. The dorsal surface is covered by a capsula externa, with the upper portion of the plate featuring a wide notch that forms a pair of sharp pointed processes at the base of the genitalia. The capsula externa also exhibits a pair of broad lateral processes. It is slightly lower than the capsula interna, which is laterally flattened and compressed between the lateral processes of the capsula externa. The capsula interna does not have a visible stylus. Additionally, there is a dorsolateral plate connected to the pars basalis.
Female. Similar to males, with a shorter pedipalpal femora.
