Paradysderina puyo , new species Figures 428–441

TYPES: Male holotype and female allotype from tropical forest litter taken at an elevation of 800 m at Puyo, Pastaza, Ecuador (Apr. 1965; J., N. Leleup), deposited in KBIN (PBI_OON 16669) .

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

DIAGNOSIS: Males have both flanges of the embolus straight, elongated, and club shaped (figs. 432–435) and deeply excavated chelicerae (fig. 429); females resemble those of P. zamora but have a long anterior genitalic process (figs. 440, 441).

MALE (PBI_OON 16669, figs. 428–435): Total length 1.82. Elevated portion of pars cephalica granulate. Chilum short, wide, triangular. Anterior ledge of paturon with small tubercle situated near middle of anterior surface, inner margin deeply excavated, with dark, anteriorly directed spine. Endites with ventral process much wider, longer than dorsal process. 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 elongated, originating at about half of bulb length, both flanges long, straight, parallel, basal portion of dorsal flange closely appressed to bulb surface.

FEMALE (PBI_OON 16669, figs. 436– 441): Total length 1.54. Chilum tiny. Postepigastric scutum covering about one-third of abdomen length, fused to epigastric scutum. Leg spination: femora: I p0-0-2, II p0-0-1; tibiae I, II v4-4-1p; metatarsi: I, II v2-2-0. Narrow anterior genitalic process originating from wide base occupying most of atrial width.
