Paradysderina baehrae , new species Figures 464–477

TYPES: Male holotype and female allotype taken by hand collecting at an elevation of 2400 m at the Yanayacu Biological Station , 0 ° 36.4969S, 77 ° 52.9479W, Napo, Ecuador (Nov. 28, 2009; B. Baehr, Niarchos Exped. ), deposited in QCAZ (PBI_OON 585) .

ETYMOLOGY: The specific name is a patronym in honor of Barbara Baehr, collector of the types.

DIAGNOSIS: Males have a distinctive embolus, with a small barb set back from the tip (figs. 468–471), and differ from those of the sympatric species P. yanayacu in lacking deep excavations on the chelicerae (fig. 465); females of both share a long anterior genitalic process, extending anterior of the anterior spiracles, but have a smaller subdistal widening on the anterior genitalic process (figs. 476, 477).

MALE (PBI_OON 585, figs. 464–471): Total length 1.80. Elevated portion of pars cephalica granulate. Chilum short, wide, triangular. Anterior ledge of paturon with heavily sclerotized, medially directed ridge bearing medially directed denticles. Endites with ventral process wide, with short tip, dorsal process narrow, with long, medially directed tip. Leg spination: femur I p0-0-2; tibiae: I v4-4-1p, II v4-3-0; metatarsi I, II v2- 2- 1p. Palps symmetrical; embolus with small barb set back from tip on dorsal edge.

FEMALE (PBI_OON 585, figs. 472–477): Total length 2.03. Postepigastric scutum only around epigastric furrow, fused to epigastric scutum. Leg spination: femora: I p0-0-2, II p0-0-1; tibiae: I v4-4-1p, II v4-4-0; metatarsi:

I v2-2-2, II v2-2-0. Anterior genitalic process with small, subdistal widening.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Ecuador (Napo).

Paradysderina righty , new species Figures 478–495 TYPES : Male holotype and female allotype taken by hand collecting at an elevation of

2400 m at the Yanayacu Biological Station , 0 ° 36.4969S, 77 ° 52.9479W (Nov. 28, 2009; B. Baehr, Niarchos Exped. ), Napo, Ecuador deposited in QCAZ (PBI_OON 586) .

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

DIAGNOSIS: Males have highly asymmetric palps, with the left palp uninflated and shorter than the right palp; the emboli are similarly simple and distally twisted (figs. 482–489), and the chelicerae have a darkened protrusion near the fang furrow. Females have a sclerotized plate that almost fills the genital atrium (figs. 494, 495).

MALE (PBI_OON 586, figs. 478–489): Total length 1.89. Elevated portion of pars cephalica granulate. Chilum small, thumb shaped. Paturon with small, sharply pointed, heavily sclerotized, dorsally directed spine situated just dorsal of cheliceral tooth. Endites with ventral, dorsal processes both wide, sharply pointed. Leg spination: femur I p0-0-2; tibiae I, II v4-4-1p; metatarsi: I v2-2- 1p, II v2-2-0. Left palpal bulb small, narrow; right bulb greatly inflated; embolus short, bent medially at about half its length.

FEMALE (PBI_OON 586, figs. 490–495): Total length 2.35. Postepigastric scutum only around epigastric furrow, fused to epigastric scutum. Leg spination: femora I, II p0-0-2; tibiae: I v4-4-2, II v4-4-1p; metatarsi: I v2-2- 2, II v2-2- 1p. Atrium semicircular, almost entirely filled with semicircular sclerotization.

Paradysderina centro , new species

Figures 496–508.

TYPES: Male holotype and female allotype taken at an elevation of 220 m at the Centro Cientifico Río Palenque, 0 ° 549S, 79 ° 009W, Los Ríos, Ecuador (Mar. 2, 1979; S. Sandoval), deposited in QCAZ (PBI_OON 10738) .

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

DIAGNOSIS: Males have a distinctive embolus that is very narrow at its base, then flared, and finally twisted (figs. 499–502); females have triangular, anterolateral sclerotizations in the genital atrium (figs. 507, 508).

MALE (PBI_OON 10785, figs. 496–502): Total length 1.32. Elevated portion of pars cephalica appears reticulate. Chilum tiny, triangular. Aside from anterior swelling, paturon unmodified. Endites with ventral process wide, dorsal process with long, narrow tip. Leg spination: femur I p0-0-1; tibiae: I v4-4-0, II v2-2-2; metatarsi: I v2-2- 1p, II v2-2-0. Palps symmetrical; embolus narrow at base, then flared, distally twisted.

FEMALE (PBI_OON 10785, figs. 503– 508): Total length 1.66. Postepigastric scutum only around epigastric furrow, fused to epigastric scutum. 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. Atrium with anterolateral, fingerlike sclerotizations; apodemes inconspicuous.
