Paradysderina macho , new species Figures 187–195

TYPE: Male holotype taken at an elevation of 1720 m at Quellouno , Alto Lorohuacana, Calca, 12 ° 35911.050S, 72 ° 31907.190W, Cusco, Peru (Dec. 14, 2009; W. Paredes), deposited in MUSM (501269, PBI_OON 543) .

ETYMOLOGY: The specific name, meaning male in Spanish, refers to the exaggerated, darkened appearance of the male, with enlarged swellings that almost double the thickness of the chelicerae.

DIAGNOSIS: Males can easily be recognized by their darkened coloration (the carapace and abdominal scuta are dark reddish brown, the dorsal scutum has a submarginal, Ushaped row of lighter spots (fig. 189), the postepigastric scutum has a W-shaped row of submarginal, lighter spots, and the leg coxae and femora are darkened) and by the highly modified chelicerae (fig. 188); the embolus is short and wide (figs. 192–195).

MALE (PBI_OON 543, figs. 187–195): Total length 1.92. Elevated portion of pars cephalica granulate. Chilum large, long, triangular. Paturon with anterior swelling greatly produced, almost doubling thickness of chelicerae, bearing long, sharply pointed, ventrally directed, median prong at ventral edge of swelling; inner margin with heavily sclerotized, dorsally directed spine at base. Endites anteriorly with two long, narrow, clawlike processes. Leg spination: femur I p0- 0-2; tibiae: I v4-4-2, II v4-4-1p; metatarsi: I v2-2-2, II v2-2- 1p. Palps symmetrical; embolus short, wide, extending across distal tip of palpal bulb.
