Diagnosis for males. Nanophareus bosqenublado sp. nov. resembles N. araucanus sp. nov. because of the frontal hump on dorsal scutum with an enlarged, high median tubercle, coxa IV reaching close to the posterior margin of dorsal scutum in dorsal view, prolateral apical apophysis of coxa IV surpassing the posterior margin of dorsal scutum, trochanter IV with a prodorsal apical apophysis and femur IV with a retromedian apophysis. Nanophareus bosqenublado sp. nov. can be distinguished from N. araucanus sp. nov. by: Widened and unarmed ocularium, prolateral apical apophysis of coxa IV bifid from the subasal area, prodorsal apical apophysis of trochanter IV long and pointed and patella IV with two ventral spines. Nanophareus bosqenublado sp. nov. can be distinguished from the other species of the genus by the: Coxa IV prolaterally with a dorsal apical apophysis, bifid from subasal region, directed backwards, dorsal branch longer than ventral one, and retrolaterally with a short apical apophysis; trochanter IV with a dorsoapical long apophysis curved to tip of dorsal branch of coxa IV prolateral apical apophysis; femur IV ventrally with 1 retrolateral subapical very long spine and 1 prolateral apical spine; patella IV with a proventral apical spine directed posteriorly and a retroventral subapical spine directed ventrally; tibia IV with two ventral rows of high, enlarged tubercles, retrolateral ones largest, prolateral ones decreasing in size apicad, ventroapically with a prolateral tubercle and a retrolateral spine.
Diagnosis for females. Nanophareus bosqenublado sp. nov. can be distinguished from the other species of the genus by the combination of the following characters: Ocularium widened; frontal hump armed with enlarged median tubercles; and scutal area IV undivided.
Etymology. In reference to the remarkable habitat where the holotype material has been collected.

Trochanters I–IV tuberculate; IV twice longer than wide, concave dorsally, prolaterally with a wide median apophysis with truncate apex, a dorsoapical long apophysis (approximately trochanter length) curved to tip of dorsal branch of coxa IV prolateral apical apophysis; retrolaterally with an enlarged median pointed tubercle and a short, conical apical apophysis. Femur IV straight, dorsally and laterally with some enlarged rounded tubercles, a medium sized (length approximately ¼ of femur IV length) prodorsal apical blunt spine, a medium sized retrodorsal apical blunt spine, an enlarged dorsomedian apical tubercle; retrolaterally with a subasal and a median spines; ventrally with a retrolateral row of tubercles increasing in size from the base to the middle length of femur; a prolateral row of tubercles increasing in size apically; one retrolateral, subapical, very long spine, and one prolateral apical spine. Patella IV densely covered by rounded enlarged tubercles, with a proventral apical spine directed posteriorly and a retroventral subapical spine directed ventrally. Tibia III with a proventral row of enlarged tubercles; IV with two ventral rows of high, enlarged tubercles, retrolateral ones largest, prolateral ones decreasing in size apically, ventroapically with a prolateral tubercle and a retrolateral spine. Metatarsus IV with slightly enlarged tubercles on basal ½. Basitarsus I slightly swollen. Tarsal process reduced to a seta. Tarsal segmentation: 6(3); 10(3); 6; 6.

Geographical distribution ( Fig. 13 View FIGURE 13 ): E Chile. Coquimbo and Valparaíso.
Biotope note. Nanophareus bosqenublado sp. nov. was collected in Rain Forest islands in the middle of semiarid environment. The distribution of this species coincides with forest of Aextoxicon punctatum (known in Chile as olivillo, an Aextoxicaceae tree), which was almost continuous for about 650 km from Fray Jorge to south before European occupation (see Squeo et al. 2005). Northern record of N. bosqenublado sp. nov. are in forested areas that have canopies about 13–17 m high and which are found in patches of about 5 ha in Sorón (near Parque Nacional Fray Jorge main office) and smaller sizes in Cerro Talinay, Cerro Santa Ines and localities of Region de Valparaíso. These patches have been isolated since the late Tertiary and they are located on coastal mountaintops (only at 450–600 m), surviving on the moisture input from fog. Southern records are also in forests dominated by olivillo trees, in coastal mountain slopes or in ravines. For more details on this biotope, see Squeo et al. (2004, 2005) and del-Val et al. (2006).
