Paradysderina monstrosa , new species Figures 703–708 , 721–732

TYPES: Male holotype and female allotype from Winkler trap in secondary forest at an elevation of 3220 m at Sutamarchán, Serranía Marchán, 5 ° 459010N, 73 ° 409020W, Boyacá, Colombia (Apr. 7–9, 2003; E. González, C. Reina), deposited in IAVH (108122, PBI_OON 636) .

ETYMOLOGY: The specific name is an arbitrary combination of letters.

DIAGNOSIS: Males can easily be recognized by their palpal dimorphism; the left embolus is V-shaped (fig. 725), whereas the right embolus is blade shaped (fig. 726); females have a large genital atrium with a triangular posteromedian sclerotization (figs. 706–708).

MALE (PBI_OON 636, figs. 721–732): Total length 1.80. Elevated portion of pars cephalica appears reticulate. Chilum tiny, triangular. Anterior ledge of paturon obliquely oriented, with slight tubercle at inner edge. Endites with dorsal process much wider, longer than ventral process. Leg spination: femur I p0-0-1; tibiae: I v4-4-0, II v4-2-0; metatarsi: I v2-2-1p, II v2-2-0. Left embolus V-shaped, right embolus blade shaped.

FEMALE (PBI_OON 636, figs. 703–708): Total length 1.83. Postepigastric scutum only around epigastric furrow, fused to epigastric scutum. Leg spination: femur I p0-0-2; tibiae I, II v4-4-1p; metatarsi: I v2-2-1p, II v2-2-0. Atrium very large, longer than portion of postepigastric scutum posterior of atrium; base of anterior genitalic process short, triangular, restricted to posterior half of atrium.
