Description.

MALE: Measurements (n =3) DSW: 3.4-4.1 (4.0); DSL: 4.2-5.0 (4.8); CL: 1.4-1.7 (1.7). FIVL: 3.3-4.0 (3.5). ChL: 1.7-2.8 (2.4) Coloration (alive): Yellowish with black spots on carapace, lateral part of the scutal areas I-IV, lateral margins of dorsal scutum and legs. Dorsum: (Fig. 2G) Alpha-type DSS. Anterior margin of DS with median elevation with granules densely distributed. Granular ocularium, with two pairs of small tubercles taller than others. Carapace with granules densely distributed. Areas I-IV densely granulate; each one with a pair of median tubercles. Lateral margins of dorsal scutum with granules distributed throughout their length. Posterior margin of dorsal scutum and free tergites I-III with a row of acuminate tubercles, larger than those tubercles of areas of dorsal scutum, interspersed by small granules. Chelicerae: (Fig. 2G) Swollen in large males (Swollen in holotype). Slightly larger than females’ chelicerae in smaller males. Segment I granulate. Segment II predominantly smooth. Segment III with one tooth. Pedipalpus: Small granules distributed on the dorsal surface. Trochanter with a ventrodistal setiferous tubercle. Femur with a ventrobasal setiferous tubercle; a row of 5-6 ventrodistal median setiferous tubercles. Tibia: prolateral II, retrolateral iIii. Tarsus: prolateral Iii, retrolateral Iii. Venter: Coxa I with a median row of 4-5 small tubercles. Coxae II-IV and genital area with few scattered granules. Free sternites with a row of small granules. Anal operculum with granules sparsely distributed across its surface. Legs: (Figs 2G, 7K, L) Coxae I-II each one with a prolateral and a retrolateral apophyses; III with only prolateral apophysis; coxa II retrolateral and coxa III prolateral apophyses fused; IV with granules distributed throughout its surface, with a proapical spiniform apophysis. Trochanters I-III smooth; IV with 3-4 small dorsoapical tubercles and a larger retroapical median acuminate tubercle. Femora I-III with scattered granules; IV granular; with a retroventral row of three small acuminate tubercles and one large apical tubercle; a proventral row of 9-10 small tubercles, growing apically, and four large tubercles with curved apex; a prolateral row of 15-16 lanceolate tubercles, with the most basal slightly larger than granules, the most apical large, covering the entire length of segment; a retrolateral row of 11-12 tubercles. The shape of of retro- and prolateral tubercles are extremely variable and can have a blunt, acuminate or truncated apex. Patellae I-III with sparse granules; IV densely granulate dorsally, with more sparsely distributed granules on the ventral face, with three apical retrodorsal tubercles and a greater dorsoapical acuminate tubercle. Tibiae I-IV granular; IV with a row of 11-13 acuminate tubercles, growing apically. Tarsal segmentation: (n =3) 7, 8-10 (10), 6-7 (7), 7-8 (8). Penis: (Fig. 15D-F) VP rectangular; distal margin straight, with conspicuous laterodistal projections; slightly curved in lateral view. MS C1-C4 distal long and curved; MS A1 long and straight, medially placed; MS B1 sub basal long and straight; MS D1 very short, laterodorsally placed. Lateral sacs long, robust and with wider apex; with long T3-like microsetae. Stylus with triangular apex, with rounded corners; with a ventral projection with setae. Promontory straight. - FEMALE: Measurements (n =15) DSW: 3.5-3.6; DSL: 4.0-4.5; CL: 1.4. FIVL: 3.3-3.5. ChL: 1.2-1.4 Chelicerae similar to that of small males. Pedipalpus femur with a proapical spine. Femur IV unarmed. Tarsal segmentation: (n =15) 6, 9-10, 7, 7.

Diagnosis.

Similar to Ayacucho tapacocha nom. nov. because the tibia IV is armed (Fig. 7K, L). Differs from Ayacucho tapacocha nom. nov. because DSS with constriction II most marked (Fig. 2G); the presence of basal tubercles in a prolateral row in femur IV (totaling 15-16; 11-12 in A. tapacocha nom. nov.); retroventral row of femur IV with less than 5 tubercles (7-9 in A. tapacocha nom. nov.); presence of tubercles on the basal retrolateral row of tibia IV (Fig. 7K, L); two pairs of small tubercles in ocularium; coxa III retrolateral apophysis absent (Fig. 2G).

Derivatio nominis.

The specific epithet, a noun in apposition, in reference to the type locality, Laguna Querococha, a blue waters lagoon, from glacier of Parque Nacional Huascaran, Department of Ancash, type locality of the species.
