Paradysderina pithecia , new species Figures 386–398

TYPE: Male holotype taken by fogging at Pithecia, Río Samiria, 05 ° 159S, 74 ° 409W, Loreto, Peru (May–June 1990; T. Erwin et al.), deposited in MUSM (PBI_OON 40809) .

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

DIAGNOSIS: Males can be recognized by the abruptly bent embolar tip (figs. 389–392); females resemble those of P. thayerae in having a long, triangular anterior genitalic process, but lack the distinct lateral atrial sclerotizations found in that species (figs. 396–398).

MALE (PBI_OON 40809, figs. 386–392): Total length 1.49. Elevated portion of pars cephalica granulate. Chilum tiny, triangular. Anterior ledge of paturon with only slight tubercle at inner margin, inner margin with pair of dark, heavily sclerotized, dorsally directed spines. Endites with ventral process wide, short, dorsal process narrow, short. Leg spination: femur I p0-0-2; tibiae: I v4-4- 0, II v4-2-0; metatarsi: I v2-2-0, II v2-0-0. Palps symmetrical; embolus distally bifid, with sharply pointed, narrow, straight distal prong.

FEMALE (PBI_OON 548, figs. 393–398): Total length 1.86. Postepigastric scutum only around epigastric furrow, not fused to epigastric scutum. Leg spination: femora: I p0-0-2; r0-1-2, II p0-0-2; r0-2-0; tibiae: I v4- 4-2, II v4-4-1p; metatarsi: I v2-2-2, II v2-0-2. Atrium ovoid, anterior process with enlarged base occupying about half of atrial width.

OTHER MATERIAL EXAMINED: Peru: Loreto: Río Samiria, ca. 05 ° 089S, 75 ° 119W, May–June, 1990, fogging (T. Erwin, D. Silva, MUSM PBI_OON 548), 5♀.

DISTRIBUTION: Peru (Loreto).
