Paradysderina asymmetrica , new species Figures 140–157

TYPE: Male holotype taken in pitfall trap at an elevation of 465 m at Río Camisea , Pagoreni, 11 ° 42922.50S, 72 ° 54910.70W, Cusco, Peru (May 7–28, 1998; S. Córdova), deposited in MUSM (501435, PBI_OON 534) .

ETYMOLOGY: The specific name refers to the differences between the right and left palps.

DIAGNOSIS: Males can easily be distinguished by uninflated right palp (figs. 149– 151) and the cross-shaped embolus (figs. 144, 145), females by the complex, wide anterior genitalic process (figs. 155–157).

MALE (PBI_OON 534, figs. 140–151): Total length 1.45. Elevated portion of pars cephalica appears reticulate. Chilum short, relatively wide. Paturon with strongly produced anterior ledge bearing small, sharp, ventrally directed process, inner margin with strong, heavily sclerotized spine. Endites anteriorly with two strong, curved, clawlike processes. Leg spination: femur I p0-0-1; tibiae: I v4-4-0, II v4-3-0; metatarsi: I v2-2- 1p, II v2-1p-0. Right palp much less inflated than left palp, widened distally; right embolus with distal half much longer, directed more medially than left embolus.

FEMALE (PBI_OON 537, figs. 152–157): Total length 1.62. Chilum small, triangular. Postepigastric scutum covering about onethird of abdomen length, fused to epigastric scutum. Leg spination: femora: I p0-0-2, II p0-0-1; tibiae I, II v4-4-1p; metatarsi I, II v2- 2- 1p. Anterior genitalic process heavily sclerotized, wide, darkest along midline.
