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 : 70

Reductoonops napo , new species ( figs. 453–468 )

TYPE: Male holotype taken at an elevation of 1005 m in the Parque Nacional Napo-Galeras , 00°44′00″S, 77°28′07″W, Napo, Ecuador (Nov. 27, 2009; Niarchos Exped. ), deposited in QCAZ (PBI_OON 51323) .

DIAGNOSIS: Males and females have not been taken together and are only tentatively matched here, but they show similarly odd and seemingly autapomorphic genitalic characters. Males can easily be recognized by the lobate palpal apophysis ( figs. 460–463 ), females by the sharply pointed cap on the tip of the anterior genitalic process ( figs. 467, 468 ).

MALE (PBI_OON 51323, figs. 453–464 ): Total length 1.07. 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 indented at middle. Endite tip with sharply pointed, diagonally directed projection. Palpal apophysis lobate, embolus and conductor apparently fused; cymbium not fused with bulb.

FEMALE (PBI_OON 51325, figs. 465–468 ): Total length 0.90. Anterior genitalic process relatively wide, tip rounded, with sharply pointed lateral extensions.

OTHER MATERIAL EXAMINED: ECUADOR: Napo: Sacha Wagra Lodge, Río Hollín , 00°57′18″S, 77°44′51″W, Nov. 29, 2009, elev. 665 m ( Niarchos Exped., AMNH PBI _OON 51324), 2♀ , Berlese , litter from humid forest with karstic rocks, elev. 750 m (M. Ramírez et al., Niarchos Exped., MACN PBI _OON 51325), 2♀ .

DISTRIBUTION: Ecuador (Napo).
