MALE: Measurements (n =9) DSW: 3.3-3.4 (3.3); DSL: 4.6-5.2 (4.6); CL: 1.5-2.0 (1.5). FIVL: 5.0-5.3 (5.0). ChL: 1.7-3.0 (2.1). Coloration: (Fig. 22A View Figure 22 ): Predominantly orange, with two longitudinal black spots in the lateral portion of areas I-IV. Lateral margins of the dorsal scutum yellowish, with small black spots. Posterior margin of the dorsal scutum, free tergites and legs predominantly black. Chelicerae and pedipalpus orange and reddish. Dorsum: (Fig. 2B View Figure 2 ) Alpha-type DSS, with the constrictions weakly marked (when compared to most Ayacucho spp.). Anterior margin of carapace covered with granules in all its width. Ocularium unarmed, smooth or with a few granules in some individuals. Carapace with scattered granules distributed throughout its surface. Areas I-IV with one pair of small median tubercles; densely granulate. Posterior margin of dorsal scutum with a median row of 6-8 (6) acuminate tubercles (larger than tubercles of areas I-IV). Free tergites I-III with a row of tubercles similar to those on the posterior margin of dorsal scutum. Chelicerae: (Fig. 2B View Figure 2 ) Swollen in some males (not swollen in the holotype). Segment I covered with granules throughout their length. Segment II predominantly smooth; finger with three teeth. Segment III with two teeth. Pedipalpus : With granules sparsely distributed on the dorsal surface of the femur and patella. Trochanter with a distal ventral setiferous tubercle. Femur with a ventrobasal setiferous tubercle and a row of 5-6 (5) small ventromedial setiferous tubercles. Tibia: prolateral IIII, retrolateral IIII. Tarsus: prolateral IIi, retrolateral Iii. Venter: Coxa I with scattered small tubercles; coxae II-III, predominantly smooth, with sparse granules; Coxa IV with denser granulation than coxae II-III. Genital area smooth. Free sternites I-IV and anal operculum with granules sparsely distributed. Legs: (Figs 2B View Figure 2 , 7C, D View Figure 7 ) Coxa I with a prolateral apophysis; coxa II with a retrolateral and a prolateral apophysis. Coxa IV densely granulate. Trochanters I-IV with few granules, unarmed. Femora I-IV, with granules distributed throughout its length. Tarsal formula: (n = 9) 7-8 (7), 11, 7, 8. Penis: (Fig. 16D-F View Figure 16 ) VP subrectangular; distal margin with a V-notch, and with conspicuous laterodistal projections; slightly curved in lateral view. MS C1-C7 subdistal long and curved; MS A1 long and straight; medially placed; MS B1 sub basal long and straight; MS D1 subdistal very short, dorsally placed. Lateral sacs long and apically acuminate; with long T3-like microsetae. Stylus apically robust and with projections. Dorsal process absent. Promontory convex. - FEMALE: Measurements (n =10) DSW: 3.5-4.0; DSL: 4.5-5.2; CL: 1.6-1.8. FIVL: 4.7-5.6. ChL: 1.7-2.1. (Fig. 22B View Figure 22 ) Chelicerae not swollen. Strongly similar to small males. Tarsal segmentation: (n =10) 6, 10-11, 7, 8.


Similar to Ayacucho pomacocha sp. nov., A. silvae sp. nov., A. titschacki and A. vargasllosai sp. nov. 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. 2B View Figure 2 ); femur IV of males without strong armature (except in ventral surface of femur IV in A. silvae sp. nov., Fig. 7C, D View Figure 7 ). It differs from the four previously mentioned species in the following combination of characteristics: DSS with weakly marked constrictions (Fig. 2B View Figure 2 ); ocularium unarmed and smooth or with a few granules (Fig. 2B View Figure 2 ); male femur IV unarmed (unlike A. silvae sp. nov., Fig. 7C, D View Figure 7 ); and penis VP subrectangular with a V-notch on distal margin (Fig. 16D, F View Figure 16 ).

Derivatio nominis.

The specific epithet of masculine gender, in the genitive form, dedicated to the Brazilian filmmaker, actor and writer Glauber de Andrade Rocha (1939-1981).
