MALE: Measurements (n =1) DSW: 3.3; DSL: 4.6; CL: 1.7. FIVL: 4.7. ChL: 2.5. Coloration: (Fig. 23F View Figure 23 ) Chelicerae, pedipalpus, carapace and lateral margin of dorsal scutum and legs orange. Scutal areas, posterior margin of dorsal scutum and free tergites brownish. Dorsum: (Fig. 3G View Figure 3 ) Alpha-type DSS, with shallower constrictions. Anterior margin of carapace with median elevation totally covered with granules. Ocularium with tiny acuminate tubercles. Areas I-IV with one pair of small median tubercles (larger than the pair of the ocularium). Posterior margin of dorsal scutum with a transverse row of four tubercles. Free tergites I--III with a row of 3-6 tubercles, larger than tubercles of areas I-IV. Chelicerae: (Fig. 3G View Figure 3 ) Swollen in male. Segment I densely covered with granules throughout its length. Segment II predominantly smooth, with some hairs on the front surface; finger with four teeth. Segment III with two teeth. Pedipalpus : With very small granules sparsely distributed on the dorsal surface of the femur-tibia. Trochanter with a distal ventral setiferous tubercle. Femur with a ventrobasal setiferous tubercle and a row of five small ventromedian setiferous tubercles. Tibia: prolateral IIII, IiI; retrolateral iII(II), iIII. Tarsus: prolateral IIi; retrolateral Iii, Ii. Venter: Coxae I-IV and stigmatic area with sparse small granules; coxa I with a longitudinal row of small setiferous tubercles. Genital area smooth. Free sternites I-IV and anal operculum with sparse small granules. Legs: (Figs 3G View Figure 3 , 8C, D View Figure 8 ) Coxae I-III each one with a retrolateral and a prolateral apophysis. Coxa IV densely granulate, unarmed. Trochanters I-IV densely granulate, unarmed. Femora I-IV densely granulate throughout their dorsal, retrolateral and prolateral faces. Femora I-III with two rows of granules in the ventral face, larger than other granules of these segments. Femur IV with two ventral rows of granules that increase in size apically, greater than other granules of femur IV. Patellae I-IV densely granulate. Tibiae I-IV granulate (larger granules on ventral face). Tarsal segmentation: (n = 1) 7, 11, 7, 7. Penis: (Fig. 13A, B View Figure 13 ) VP subrectangular in dorsal view, with distal half larger than basal half; distal margin straight. MS C1-C7 (C8) apical, long and curved; MS A1 median placed, long and straight (smaller than MS C); MS B1 sub basal, long and straight (smaller than MS A). Lateral sacs long, apically tapered; with long T3-like microsetae. Stylus apically inflated, with a conspicuous ventral projection. Dorsal process absent. Promontory straight. - FEMALE: Measurements (n=3) DSW: 3.0-3.1; DSL: 4.4-4.5; CL: 1.7. FIVL: 4.5-4.7. ChL: 2.2-2.3. Areas I-IV with one pair of small median tubercles, smaller than in males. Pedipalpus with ventral tubercles slightly smaller than in males. Tibia: prolateral IiI; retrolateral iIIIi, iIII. Tarsus: retrolateral iIIi, iIii. Genital area with sparse granules. Femur IV with ventral tubercles smaller than in males. Tarsal segmentation (n =3): 7,11,7,8.


Similar to Ayacucho glauberrochai sp. nov. A. pomacocha sp. nov., A. silvae sp. nov., and A. titschacki in the following combination of characteristics: dorsal scutum densely granulate; ocularium and areas I-IV of DS unarmed or armed with tiny tubercles, slightly greater than granules; posterior margin of DS and free tergites I-III with median rows of acuminate tubercles (Fig. 3G View Figure 3 ); femur IV of males without strong armature (except in ventral surface of femur IV in A. silvae sp. nov.; Fig. 8C, D View Figure 8 ). It differs from the previously mentioned species in the following combination of characteristics: ocularium with a pair of small tubercles; areas I-IV with a pair of tubercles (larger than those in ocularium; Fig. 3G View Figure 3 ); male femur IV unarmed (unlike A. silvae sp. nov.; Fig. 8C, D View Figure 8 ); and penis VP subrectangular, with 7-8 apical MS C (Fig. 13A, B View Figure 13 ).

Derivatio nominis.

The specific epithet of masculine gender, in the genitive form, dedicated to the Peruvian writer, politician, journalist, essayist, filmmaker, college professor and Nobel Prize winner Jorge Mario Pedro Vargas Llosa (born 1936), more commonly known as Mario Vargas Llosa.
