Reductoonops tandapi , new species ( figs. 353–372 )

TYPES: Male holotype and male paratype sorted by hand from cloud forest litter taken at an elevation of 2150 m at a site 21 km north of Tandapi , on the main road from Tandapi to Quito, 00°27′20.3″S, 77°45′15.5″W, Pichincha, Ecuador (Dec. 7, 2009; N. Dupérré, E. Tapia, Niarchos Exped. ), deposited in QCAZ (PBI_ OON 51317 ), plus male paratype, same data, deposited in AMNH (PBI_ OON 49613 ) .

DIAGNOSIS: Males can be recognized by the shape of the palpal apophysis, which in ventral view is moderately wide at its base and for about two-thirds of its length, with a narrowed distal portion ( fig. 364–367 ); females have the anterior genitalic process wider at the tip than at its middle, placed in a relatively wide, shallow boat-shaped structure, but lack lateral expansions on the tip of the anterior genitalic process ( figs. 371, 372 ). Compared to the sympatric species R. pichincha , these animals have much larger eyes ( figs. 353, 354 , 370 ), and more widespread sternal setae ( figs. 368, 369 ).

MALE (PBI_ OON 51317 , figs. 353–368 ): Total length 1.17. Surface of elevated portion of pars cephalica smooth. Eyes two; ALE separated by less than their radius. Sternum with anterior channels, surface smooth, without pits, microsculpture absent; setae evenly scattered. Labium anterior margin indented at middle. Endites with anterolateral edge enlarged, rounded. Palpal apophysis moderately wide for two-thirds its length, then abruptly narrowed distally; cymbium not fused with bulb.

FEMALE (PBI_ OON 51318 , figs. 369–372 ): Total length 1.19. Anterior genitalic process wider at tip than at middle but tip without lateral expansions, process placed in relatively wide, shallow boat-shaped structure.

OTHER MATERIAL EXAMINED: ECUADOR: Pichincha: 15 km E Tandapi, June 7, 1976, Berlese , moss, forest litter, elev. 2300 m (S. Peck, FMNH PBI_ OON 10565 ), 1♂, 2♀ ; 21 km N Tandapi, on main road from Tandapi to Quito , 00°27′20.3″S, 77°45′15.5″W, Dec. 7, 2009, Berlese, cloud forest litter, elev. 2150 m (N. Dupérré, E. Tapia, Niarchos Exped., AMNH PBI _ OON 51318 ), 1♂, 2♀ .

DISTRIBUTION: Ecuador (Pichincha).
