Oonops desultrix Keyserling, 1881: 301  , fig. 21 (female holotype from “ Pumamaria ” [presumably the famous archeological ruins at Pumamarca, Cusco], Peru, supposedly deposited in University of Warsaw collection, lost).

Dysderina desultrix: Simon, 1893: 304  .

DIAGNOSIS: Males resemble those of P. yungas  and P. manu  but differ from those of the former by lacking a dorsal lobe on the tip of the conductor and from those of both species by having a thicker embolus (figs. 65–67); females differ from those of both species by having a much less expanded tip on the anterior genitalic process (figs. 71, 72). Both sexes have submarginal denticles on the carapace (fig. 2) that are absent in P. yungas  .

MALE (PBI_ OON 10053View Materials, figs. 1–30, 61–68): Total length 1.98. Surface of elevated portion of pars cephalica appearing finely reticulate; lateral margin with blunt denticles. ALE separated by less than their radius. Postepigastric scutum long, almost rectangular, extending to nearly full length of abdomen. Leg spination: femur I p0-0-2, r1-1-0; tibiae: I v4-4-2; II v4-4-0; metatarsi: I v2-1p-2; II v2-0-2. Embolus short, narrow, bent at about two-thirds its length, conductor with slight prolateral projection at base, wider retrolateral projection near tip.

FEMALE (PBI_ OON 10053View Materials, figs. 31–60, 69–72): Total length 2.27. Dorsal scutum covering more than 3/4 of abdomen length, more than 1/2 to most of abdomen width, not fused to epigastric scutum. Postepigastric scutum almost semicircular, extending to about 3/4 of abdomen length, fused to epigastric scutum. Leg spination: femora I, II p0-0-2, r1-1-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi I, II v2-1p-2. Genital atrium wide, semicircular, posterior portion with transverse sclerotization visible through cuticle.
