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 : 14

Reductoonops monte , new species ( figs. 199–218 )

TYPES: Male holotype and female allotype taken by sifting leaf litter at an elevation of 1500 m at Monteverde , Puntarenas, Costa Rica (Feb. 23–27, 1991; H., A. Howden), deposited in AMNH (PBI_OON 1435) .

DIAGNOSIS: Males can be recognized by the hook-shaped process on the palpal apophysis, best seen in prolateral view ( fig. 210 ), females by the very wide arms at the base of the anterior genitalic process ( figs. 217, 218 ). ffle species occurs sympatrically with R. naci , but differs from that and all other known species in these characters.

MALE (PBI_OON 1435, figs. 199–213 ): Total length 0.95. 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. Endites with bipartite distal lobe situated beside short, modified seta situated at anterolateral corner. Palpal apophysis with hook-shaped projection; cymbium not fused with bulb.

FEMALE (PBI_OON 1435, figs. 214–218 ): Total length 1.34. Anterior genitalic process long, narrow, base with wide arms bearing relatively straight anterior margin.

OTHER MATERIAL EXAMINED: None

DISTRIBUTION: Costa Rica (northern Puntarenas).
