Reductoonops tina , new species ( figs. 381–397 )

TYPES: Male holotype, female allotype, and female paratype from Berlese sample of forest litter taken at an elevation of 720 m at Tinalandia, 16 km southeast of Santo Domingo, 00°17′56″S, 79°03′09″W, Santo Domingo de Los Tsáchilas, Ecuador (Dec. 6, 2009; N. Dupérré, E. Tapia, Niarchos Exped. ), deposited in QCAZ (PBI_OON 51321), plus one male and one female paratypes, same data, deposited in AMNH (PBI_OON 49611) .

DIAGNOSIS: Males can be recognized by the shape of the palpal apophysis, which in ventral view is basally narrow, greatly expanded at about half its length, and then abruptly narrowed ( figs. 389–392 ); females have a sinuous anterior genitalic process with a subdistally narrowed tip ( figs. 396, 397 ).

MALE (PBI_OON 51321, figs. 381–393 ): Total length 0.93. 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 enlarged, ridged, anterolateral lobe. Palpal apophysis, in ventral view, basally narrow, greatly expanded at about half its length, then abruptly narrowed; cymbium not fused with bulb.

FEMALE (PBI_OON 51321, figs. 394–397 ): Total length 0.95. Anterior genitalic process long, narrow, sinuous, subdistally narrowed.
