Paradysderina newtoni , new species Figures 239–253

TYPES: Male holotype and female allotype from a Berlese sample of rainforest litter taken at an elevation of 1700 m at Cordillera Azul, 39 km NE Tingo María, Huánuco, Peru (Jan. 11, 1983; A. Newton, M. Thayer), deposited in FMNH (PBI_OON 545) .

ETYMOLOGY: The specific name is a patronym in honor of Al Newton, one of the collectors of the types.

DIAGNOSIS: Males can be recognized by the fan-shaped, distally expanded embolus (figs. 249–253); females resemble those of P. apurimac but have conspicuous, paired posterolateral sclerotizations at the sides of the anterior genitalic process (figs. 242–244).

MALE (PBI_OON 545, figs. 245–253): Total length 1.69. Elevated portion of pars cephalica granulate. Chilum short, triangular. Anterior ledge on paturon with only slight, anteriorly directed tubercle. Endites anteriorly with two wide, clawlike processes, both basally widened. 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 fan shaped, recumbent.

FEMALE (PBI_OON 545, figs. 239–244): Total length 1.76. Chilum very short. 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 v4-4-0; metatarsi: I v2-2-1p, II v2-2-0. Genital atrium very wide, with ovoid posterolateral sclerotizations; anterior genitalic process with W-shaped base.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Peru (Huánuco).
