Paradysderina fusiscuta , new species Figures 509–528

TYPES: Male holotype and female allotype taken by hand collecting in litter in a cloud forest with palms at an elevation of 1495 m near Tandapi , 2 km from the main road to Quito, 0 ° 239170S, 77 ° 499040W, Pichincha, Ecuador (Dec. 7, 2009; N. Dupérre´, E. Tapia, Niarchos Exped. ), deposited in QCAZ (PBI_OON 596) .

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

DIAGNOSIS: Males have a sickle-shaped embolus (figs. 514, 515), and the right palp is less inflated than the left (figs. 516–521); females have what appears to be a remnant of the dorsal abdominal scutum, fused to the epigastric scutum (fig. 522).

MALE (PBI_OON 596, figs. 509–521): Total length 1.54. Elevated portion of pars cephalica appears reticulate. Chilum tiny, triangular. Anterior ledge of paturon with slight knob on dorsomedian side. Endites with ventral process much shorter than dorsal process. Leg spination: femur I p0-0- 1; tibiae: I v4-4-1p, II v4-2-0; metatarsi: I v2- 2-1p, II v2-2-0. Right palp consistently different from left palp; embolus sickle shaped in prolateral view; right bulb less inflated than left.

FEMALE (PBI_OON 596, figs. 522–528): Total length 1.61. Postepigastric scutum only around epigastric furrow, fused to epigastric scutum. Leg spination: femora: I p0-0-2, II p0-0-1; tibiae: I v4-4-2, II v4-4-1p; metatarsi I, II v2-2- 1p. Anterior ridge of atrium strongly recurved, producing pair of lateral corners; anterior half of atrium sclerotized.
