Paradysderina convencion , new species Figures 174–186

TYPE: Male holotype taken in a Winkler trap at an elevation of 581 m at Reserva Comunal Matsigenga , La Convención, 12 ° 10920.980S, 73 ° 02932.480W, Cusco, Peru (Aug. 16, 2007; A. Asenjo), deposited in MUSM (501483, PBI_OON 541) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: The two sexes have not been not collected together, and may be mismatched. Males can be recognized by the gradually increasing width of the embolus (figs. 177–180), females by the basally widened anterior genitalic process (figs. 184– 186).

MALE (PBI_OON 541, figs. 174–181): Total length 1.62. Elevated portion of pars cephalica granulate. Chilum wide, triangular. Paturon with ventrally directed, median prong situated on ventral edge of anterior swelling. Endites anteriorly with two long, narrow, clawlike processes. Leg spination: femur I p0-0-2; tibiae: I v4-4-1p, II v4-4-0; metatarsi: I v2-2-1p, II v2-2-0. Palps symmetrical; embolus sinuous, ventral flange depressed, dorsal flange with dorsal tubercle.

FEMALE (PBI_OON 542, figs. 182–186): Total length 2.27. Postepigastric scutum covering about one-third of abdomen length, not fused to epigastric scutum. Leg spination: legs I, II missing. Most of atrial width occupied by wide anterior genitalic process, that process with transverse sclerotization at about level of anterior atrial margin.
