Platnick, Norman I. & Berniker, Lily, 2014, ffle Neotropical goblin spiders of the new genus Reductoonops (Araneae, Oonopidae), American Museum Novitates 2014 (3811), pp. 1-75 : 69

Reductoonops palenque , new species ( figs. 435–451 )

TYPES: Male holotype, 13 male paratypes, female allotype, and 24 female paratypes from Berlese sample of forest litter taken at an elevation of 700 ft at the Centro Científico Río Palenque , 47 km south of Santo Domingo, Los Ríos, Ecuador (May 18–30, 1975; S., J. Peck), deposited in FMNH (33701, PBI_OON 10203) .

DIAGNOSIS: Males can be recognized by the extremely long, narrow, flattened palpal apophysis ( figs. 448–451 ), females by the extremely long anterior genitalic process, which arises from a very narrow boat-shaped structure ( figs. 438, 439 ).

MALE (PBI_OON 10203, figs. 435 , 440–451 ): Total length 1.05. Surface of elevated portion of pars cephalica smooth. Eyes two; ALE touching. Sternum with anterior channels, surface smooth, without pits, microsculpture absent; setae densest laterally. Labium anterior margin deeply incised. Endite tip with triangular lobe bearing ventral ridge and two highly modified setae. Palpal apophysis long, narrow throughout most of its length, conductor long, narrow; cymbium fused with bulb but with clearly defined seam between.

FEMALE (PBI_OON 10203, figs. 436–439 ): Total length 1.10. Labium anterior margin indented at middle. Anterior genitalic process very long, gradually tapering toward tip, set in very narrow boat-shaped structure.

OTHER MATERIAL EXAMINED: ECUADOR: Los Ríos: Centro Científico Río Palenque , 47 km S Santo Domingo, May 18–30, 1975, Berlese, forest litter, elev. 700 ft (S., J. Peck, FMNH 33703 , PBI_OON 10205), 2♀ , Feb. 25, 1976, Berlese, litter under decaying fruit, elev. 260 m (S. Peck, FMNH 33725 , PBI_OON 10227), 1♂ .

DISTRIBUTION: Ecuador (Los Ríos).
