Diagnosis.
Sertaneja gen. nov. resembles Gyndoides because of the ocularium armature (despite being variable in Sertaneja ), four scute areas, a pair of paramedian spines on scute area II (except S. falcata sp. nov.) and unarmed free tergites. S ertaneja gen. nov. differs from G yndoides Mello-Leitão, 1927a by: (i) the lateral margin of DS with an external row of tubercles slightly increasing in size posteriorly, (ii) presence of the mesal apical seta on the pedipalp femur (Figs 3F View Figure 3 , 6F View Figure 6 , 9F View Figure 9 ), (iii) male trochanter IV retro-apical projection as a straight apophysis instead of a tubercle (Figs 3D View Figure 3 , 6D View Figure 6 , 9D View Figure 9 ), (iv) the absence of a retro-basal apophysis on male femur IV, (v) male femur IV bearing a prodorsal apical distinguished apophysis, (vi) male tibia IV ventral face armed, (vii) glans without ventral process (Figs 5 View Figure 5 , 8 View Figure 8 , 11 View Figure 11 ), (viii) stylus apex bearing distinct projections (Figs 5 View Figure 5 , 8 View Figure 8 , 11 View Figure 11 ), (ix) VP of penis without prominent ventral lobes (Figs 5 View Figure 5 , 8 View Figure 8 , 11 View Figure 11 ), and, (x) 4 pairs of MS A clustered instead of lined up in a row (Figs 5 View Figure 5 , 8 View Figure 8 , 11 View Figure 11 ). It differs from other Pachylinae genera by the combination of the sub-rectangular VP, 2 paralateral pairs of MS D, glans stylus bearing a dorso-apical longitudinal projection and lack of ventral process of the glans.
Description.
DS gamma (γ) to alpha (α) shaped (Figs 3A, B View Figure 3 , 6A, B View Figure 6 , 9A, B View Figure 9 ). Ocularium height at least two to up to three times the size the eye diameter, with posterior face tuberculate, and slightly close to the anterior margin of DS, in lateral view (Figs 3C View Figure 3 , 6C View Figure 6 , 9C View Figure 9 ); bearing a pair of divergent large spines (Figs 3G View Figure 3 , 9G View Figure 9 ), or a single central robust one (Fig. 6G View Figure 6 ). Four scute areas; scute areas I, II and IV with one to two pairs of slightly enlarged paramedian tubercles; scute area III with a pair of distinct paramedian elevations, ranging from acuminated tubercles (Fig. 9A, C View Figure 9 ) to large posteriorly curved spines (Figs 3A, C View Figure 3 , 6A, C View Figure 6 ). Chelicerae segment I posterior face covered with acuminated tubercles. Pedipalp femora with a mesal sub-apical setiferous tubercle. Coxa IV well developed, bearing dense and high tuberculation, with robust prodorsal apical apophysis. Trochanter III with a retro-ventral apical conical tubercle. Trochanter IV with a straight retro-apical conical apophysis (Figs 4A, C, D View Figure 4 , 7A, C, D View Figure 7 , 10A, C, D View Figure 10 ), and a short probasal apophysis. Penis VP sub-rectangular (Figs 5A View Figure 5 , 8A View Figure 8 , 11A View Figure 11 ); glans without dorsal or ventral processes (Figs 5B View Figure 5 , 8B View Figure 8 , 11B View Figure 11 ), stylus with a dorso-apical projection slightly curved posteriorly, ventral face with sub-apical transversal row of trichome-like projections. MS A group generally composed of four to five pairs of paralateral setae, at instances showing asymmetry between the sides (Fig. 8A View Figure 8 ). MS C composed by three (Figs 5 View Figure 5 , 8 View Figure 8 ) or five pairs of setae (Fig. 12 View Figure 12 ) inserted laterally on the apical third of the VP. MS D as two pairs of paralateral setae, inserted more dorsally on the VP, between de MS A and C sets. MS E as a pair of paralateral small setae, inserted ventrally near the MS C and D groups. Ventral surface of VP sparsely covered by microsetae.

Etymology.
' Sertaneja ' is a Brazilian adjective (fem.) that refers to a woman who lives in the Sertão regions in rural communities often in harsh survival conditions. Sertão is the largest sub-region of Brazilian Northeast characterized by dry climates and Caatinga vegetation.
