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 : 72-73

Reductoonops pinta , new species ( figs. 543–559 )

TYPES: Male holotype and male paratype from Pisonia litter taken on a southern slope with dry substrate at an elevation of 380 m on Isla Pinta , Galapagos Islands (Jan. 20, 1977; W. Reeder), deposited in TMM (57873, PBI_OON 36961) .

DIAGNOSIS: Males can easily be recognized by having all the terminal palpal elements fused into a single structure ( figs. 556–559 ), females by the hourglass-shaped anterior genitalic process ( figs. 546, 547 ).

MALE (PBI_OON 36961, figs. 543 , 548–559 ): Total length 1.18. 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 narrow, laterally directed lobe. Palpal apophysis, conductor, and embolus apparently fused into single structure, process on embolus still visible; cymbium completely fused with bulb, no seam visible.

FEMALE (PBI_OON 36959, figs. 544–547 ): Total length 1.69. Labium anterior margin indented at middle. Anterior genitalic process short, hourglass shaped.

OTHER MATERIAL EXAMINED: GALAPAGOS ISLANDS: Isla Pinta: Jan. 19, 1977, from dry litter and mineral soil at base of Pisonia , southern slope, camp area, elev. 250 m (W. Reeder, TMM 30400, PBI_OON 36960), 1♀, July 18, 1977, screened from damp Zanthoxylum and Salvia litter 2–4 cm above ash soil, elev. 400 m (W. Reeder, TMM 57874, PBI_OON 36959), 2♀.

DISTRIBUTION: Galapagos Islands ( Isla Pinta).
