Redescription.

MALE: Measurements (n =2) DSW: 4.5; DSL: 4.6-5.0 (5.0); CL: 1.5-1.7 (1.5). FIVL: 4.2-4.5 (4.5). ChL: 1.5-3.0 (3.0). Coloration (in ethanol): Predominantly yellowish. Areas I-IV, posterior margin of DS and free tergites I-IV brown. Dorsum: (Fig. 3F) Alpha-type DSS, with wide coda. Anterior margin of DS with median elevation with few sparsely granules. Ocularium with a pair of short spines; with granules between the spines. Carapace with few granules in the lateral regions of the ocularium, predominantly smooth in the posterior region of the ocularium. Areas I-IV few granular. Lateral margins of DS with few sparsely granules. Posterior margin of DS with 10-11 tiny tubercles. Free tergites I-III each one with a row of tiny tubercles with a wider base than their height. Chelicerae: (Fig. 3F) Swollen in the largest specimen (the holotype of Cajamarca weyrauchi); similar to the females in the other male. Segment I granular. Segment II predominantly smooth; finger with one tooth. Segment III with five teeth. Pedipalpus: Small granules distributed on the dorsal surface of the femur and patella. Trochanter with a large ventrodistal setiferous tubercle. Femur with a ventrobasal setiferous tubercle; a ventral row of four or five setiferous tubercles, larger in larger males. Tibia: prolateral iiIi, retrolateral iIi. Tarsus: prolateral IIi, retrolateral Iii. Venter: Coxa I with a median row of six small tubercles. Coxae II-IV smooth. Three tiny apical tubercles between the coxae II-III and III-IV. Genital area smooth. Free sternites with a row of granules. Anal operculum with granules sparsely distributed over its length. Legs: (Figs 3F, 8E, F) Coxae I-III each one with a prolateral and a retrolateral apophysis (largest on coxa II); retrolateral apophysis on coxa II and prolateral apophysis on coxa III fused. Coxa IV with few granules, concentrated more on the distal part, with a prodistal spiniform apophysis. Trochanters I-III smooth. Trochanter IV with 3-4 median dorsal granules and a retroapical acuminate tubercle. Femora I-III with sparse granules throughout their length. Femur IV granular; with a median dorsal row of 5-8 large acuminate tubercles, growing apically in size; a retrolateral row with 3-4 large acuminate tubercles at distal half of this article; a retroventral row of 9-13 small tubercles, some of them similar to granules; a proventral row of 6-7 large acuminate tubercles along the apical portion. Patella I-IV with sparse granulation. Tibiae I-IV granular. Tarsal formula: (n =2) 7, 11-12 (12), 6-7 (6), 8 (?). Penis: (Fig. 13C, D) VP with greater width in the median region; distal margin concave; straight in lateral view (except the apical portion). MS C1-C3 subapical long and curved or straight; MS A1-A2 median long and straight. Lateral sacs long and apically acuminated, with long T3-like microsetae. Stylus sinuous, with inflated apex, a long ventral projection and several small apical projections. Dorsal process half the length of the stylus. Promontory convex. - FEMALE: Measurements (n =7) DSW: 3.8-4.1; DSL: 4.2-4.5; CL: 1.1-1.7. FIVL: 3.4-3.6. ChL: 1.3-1.6. Chelicerae similar to that of small males. Pedipalpus femur with a proapical spine. Femur IV with a dorsal row of 3-4 acuminate tubercles, spaced apart from each other; a retrolateral row of granules, with two acuminate tubercles in the median portion; a proventral row of 15-17 small tubercles, larger in the apical portion. All tubercles present in females are smaller than those in males. Tarsal formula: (n =7) 7, 11-13, 5-7, 8.

Diagnosis.

Similar to Ayacucho bambamarca comb. nov. and A. triarmatus nom. nov. for presenting three rows of acuminate tubercles in the male femur IV (Fig. 8E, F). It differs from A. bambamarca comb. nov. and A. triarmatus nom. nov. in having a maximum of four acuminate tubercles in the retrolateral row (Fig. 8E, F); smaller tubercles in ocularium; free tergites with small tubercles (with wide base); areas I-IV with few granulation (Fig. 3F). It differs from A. bambamarca comb. nov. in having scutal areas unarmed (Fig. 3F).
