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 : 16-63

Reductoonops almirante , new species ( figs. 254–266 , 269–273 )

TYPES: Male holotype, male paratype, female allotype, and female paratype from Berlese sample of overflow of debris on ground from split tree hole 6 ft up on the trail to the dam on Nigua Creek, Almirante, Bocas del Toro, Panama ( Mar. 25, 1959; H. Dybas), deposited in FMNH (PBI_ OON10395 ) .

DIAGNOSIS: Males resemble those of the Costa Rican species R. lucha in having a triangular palpal apophysis, but have a much more sinuous embolus ( figs. 263–266 ); females also resemble those of R. lucha in having an asymmetrical anterior genitalic process, but that process is shorter and is situated on a much shorter base ( figs. 272, 273 ).

MALE (PBI_ OON 10395 , figs. 254–266 , 269 ): Total length 1.00. Surface of elevated portion of pars cephalica smooth. Eyes two; ALE touching. Sternum with anterior channels, surface smooth, without pits, microsculpture; setae densest laterally. Labium anterior margin deeply incised. Endites with bipartite terminal lobe, proximal portion with two modified setae. Palpal apophysis triangular, basal portion of embolus highly sinuous; cymbium not fused with bulb.

FEMALE (PBI_ OON 10395 , figs. 270–273 ): Total length 1.17. Labium anterior margin indented at middle. Anterior genitalic process asymmetrical, situated on short base.

OTHER MATERIAL EXAMINED: PANAMA: Bocas del Toro: Almirante , Apr. 1, 1959, Berlese, thatch on nest of snapping ant ( H. Dybas, FMNH 33890 , PBI_ OON 10392 ), 1♂ ; Almirante, trail to left of trail to dam on Nigua Creek , Mar. 30, 1959, Berlese, concentrated floor litter on hill ( H. Dybas, FMNH PBI_ OON 10402 ), 1♀ .

DISTRIBUTION: Panama ( Bocas del Toro).
