Cajamarca uniseriata Roewer, 1957: 76 (desc.), fig. 34 (femur IV); Kury 2003: 144 (cat.).

Redescription.

MALE: Measurements (n =5) DSW: 3.6-4.6 (4.4); DSL: 4.1-4.8 (4.3); CL: 1.3-1.7 (1.7). FIVL: 3.5-4.0 (4.0). ChL: 1.8-2.7 (2.6). Coloration: (Fig. 23G) Predominantly brown-orange. Trochanters lighter. Chelicerae and pedipalpus more orange. Dorsum: (Fig. 3H) Alpha-type DSS, with wide and slightly short coda. Anterior margin of dorsal scutum with granules scattered; with median elevation. Ocularium granulate, with a pair of spines. Areas I-IV covered with setiferous granules of similar size throughout their length. Lateral margins of dorsal scutum granulate. Posterior margin of dorsal scutum with a row of granules. Free tergites I-III with a row of tubercles; I with a pair of small tubercles; II-III with large acuminate tubercles. Chelicerae: (Fig. 3H) Slightly to proeminently swollen (as in the holotype). Segment I smooth. Segment II predominantly smooth, with four teeth on finger. Segment III with five teeth. Pedipalpus: Small granules distributed on the dorsal surface of the femur, tibia and patella. Trochanter with two ventrodistal setiferous tubercles. Femur with a ventrobasal setiferous tubercle; a row of five tiny ventral setiferous tubercles. Tibia: prolateral IiIi, retrolateral iIii. Tarsus: prolateral IiIii, retrolateral Iiii. Venter: Coxae I-IV with scattered small granules. Genital area with few granules. Free sternites I-III with row of small granules. Anal operculum with granules distributed throughout extension. Legs: (Figs 3H, 8A, B) Coxae I-III each one with a prolateral and a retrolateral apophysis. Coxa IV granulate, with a proapical acuminate apophysis. Trochanters I-III few granulate. Trochanter IV with some dorsal median granules; one retroapical acuminate tubercle. Femora I-IV with granules densely distributed throughout their length. Femur IV with a prolateral row of 11-13 small blunt tubercles; a retroventral row of 17-18 long and acuminate tubercles. Patellae I-III with few granules sparsely distributed. Patella IV with densely distributed granules and 3-4 dorsoapical acuminate tubercles. Tarsal formula: (n =5) 7-9 (7), 11-16 (13), 7-8 (7), 8-10 (9). Penis: (Fig. 17A-C) VP rectangular; distal margin slightly convex; slightly curved in lateral view; there is a more ventral projection, across the entire length of the VP, to the lateral sacs. MS C1-C3 subapical long and straight; MS A1 median long and straight; MS B1 sub basal long and straight (shorter than MS C and A); MS D1 very short, dorsally placed, near MS C3. Lateral sacs long, with blunt apex; without T3-like microsetae. Stylus cylindrical; with inflated apex, laterally flattened, ventrally projected. Dorsal process keel-shaped, laterally flattened. Promontory extremely elongated, triangle shaped. - FEMALE: Measurements (n =4) DSW: 3.6-3.9; DSL: 4.1-4.2; CL: 1.3-1.4. FIVL: 3.2-3.7. ChL: 1.3-1.4. (Fig. 23H) Chelicerae slightly smaller than that of males. Pedipalpus femur with a proapical setiferous tubercle, bigger than the ventral tubercles of femur. Femur IV unarmed. Tarsal segmentation: (n =4) 7, 10-12, 7-8, 8-9.

Diagnosis.

It differs from other species of the genus (with males known) by the set of the following characteristics: ocularium with a pair of spines; scutal areas unarmed; free tergites I-III with a pair of tubercles (Fig. 3H); male femur IV with a retroventral row of long acuminate tubercles (Fig. 8A, B); penial lateral sacs without T3-like microsetae (Fig. 17A-C).

Remarks.

Regarding the type of C. uniseriata: Roewer designated one male as holotype and two males as paratypes, but the type material is preserved without any distinction in the same vial. Therefore, it is not possible to recognize with absolute certainty which of the males is the holotype. Because of this, one of the males, whose femur IV most closely resembles the drawing in the original description, was separated as the holotype (although it is important to point out that the drawing does not faithfully represent any of the specimens).
