Paradysderina leticia , new species Figures 622–634

TYPES: Male holotype and female allotype from Berlese sample taken 7 km north of Leticia, Amazonas, Colombia (Feb. 20–25, 1972; S., J. Peck), deposited in AMNH (PBI_OON 37064) .

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

DIAGNOSIS: Males have long median ridges, terminating in dorsally directed spines, on the chelicerae (fig. 623) and a highly curved embolus originating on a relatively short palpal bulb (figs. 625–628); females have a large, U-shaped sclerotization occupying the lateral and posterior margins of the genital atrium (figs. 632–634).

MALE (PBI_OON 37064, figs. 622–628): Total length 1.45. Elevated portion of pars cephalica granulate. Chilum tiny, triangular. Inner surface of paturon deeply excavated, inner margin with two dorsally directed, heavily sclerotized spines. Endites with ventral process much wider than dorsal process. Leg spination: femur I p0-0-2; tibiae: I v4-4- 0, II v4-2-0; metatarsi: I v2-2-1p, II v2-2-0. Palps symmetrical; embolus originating ventrally on relatively small bulb, strongly bent at base, with recurved tip.

FEMALE (PBI_OON 37064, figs. 629– 634): Total length 1.72. Postepigastric scutum only around epigastric furrow, not fused to epigastric scutum. Leg spination: femora: I p0-0-2, r0-1-1, II p0-0-1, r0-1-0; tibiae: I v4-4- 1p, II v4-4-0; metatarsi I, II v2-2-2. U-shaped sclerotization occupying lateral and posterior margins of atrium.

OTHER MATERIAL EXAMINED: None.
