Paradysderina pinzoni , new species Figures 609–621

TYPES: Male holotype and female allotype from Quebrada el Ayo, La Pedrera, 1 ° 359S, 69 ° 319W, Amazonas, Colombia (May 2002; J. Pinzon), deposited in ICN (2222, PBI_OON 612) .

ETYMOLOGY: The specific name is a patronym in honor of Jaime Pinzón, collector of the types and sorter of many Colombian oonopids.

DIAGNOSIS: Males resemble those of P. vlad and P. imir , but have sharper clypeal projections (figs. 609, 610) and a much longer embolus (figs. 612–615); females have distinctive sclerotizations extending almost the full length of the postepigastric scutum (figs. 618–621).

MALE (PBI_OON 612, figs. 609–615): Total length 1.36. Elevated portion of pars cephalica appears reticulate. Chilum small, triangular, clypeus with pair of long, sharply pointed projections situated at about half of paturon width. Inner surface of paturon strongly excavated, inner margin bearing long, wide, dorsomedially directed, heavily sclerotized spines, right and left spines overlapping. Endites with ventral and dorsal processes divergent, dorsal process wider than ventral. Leg spination: femur I p0-0-1; tibiae: I v4-3-0, II v4-2-0; metatarsi I, II v2-2- 0. Palps symmetrical; embolus elongated, originating on basal half of bulb, with sharply pointed ventral projection.

FEMALE (PBI_OON 612, figs. 616–621): Total length 1.50. Postepigastric scutum covering about one-third of abdomen length, fused to epigastric scutum. Leg spination: femur I p0-0-2; tibiae I, II v4-4-0; metatarsi: I v2-2-1p, II v2-2-0. Both anterior and posterior receptacula visible through cuticle as distinctive sclerotizations, both wide, posterior receptaculum long, extending almost to posterior margin of postepigastric scutum, more than three times length of atrium.

OTHER MATERIAL EXAMINED: One female taken with the types.

DISTRIBUTION: Southern Colombia (Amazonas).
