Paradysderina tambopata , new species Figures 196–213

TYPES: Male holotype, female allotype, and female paratype taken from bamboo litter at Tambopata, Madre de Dios, Peru (Oct. 28, 1982; L. Watrous, G. Mazurek), deposited in FMNH (PBI_OON 10584) .

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

DIAGNOSIS: Males resemble those of P. asymmetrica in having the right palp greatly reduced (figs. 202–207); the right embolus is much wider than the left (figs. 200, 201). Females have the almost circular anterior genitalic elements filling much of the genitalic atrium in ventral view (figs. 211–213).

MALE (PBI_OON 10584, figs. 196–207): Total length 1.33. Elevated portion of pars cephalica granulate. Chilum short, wide, triangular. Paturon with medially directed prong on inner surface of anterior swelling; inner margin with obliquely ventrally direct- ed, heavily sclerotized spine. Endites anteriorly with two wide, distally curved, clawlike processes, ventral process widened. Leg spination: femur I p0-0-1; tibiae: I v4-4-0, II v4-2-0; metatarsi: I v2-2-1p, II v2-2-0. Right palp much less inflated than left palp; left embolus Scaphiella -like, twisted near base, right embolus much thicker, shorter.

FEMALE (PBI_OON 10584, figs. 208– 213): Total length 1.62. Postepigastric scutum covering about one-third of abdomen length, fused to epigastric scutum. Leg spination: femur I p0-0-2; tibiae: I v4-4-2, II v4-3-1p; metatarsi I, II v2-2- 1p. Anterior genitalic process heavily sclerotized, occupying about one-third of atrial width, with thumblike posterior sclerotization.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Peru (Madre de Dios).
