Reductoonops jatun , new species ( figs. 452 , 469–485 )

TYPE: Male holotype taken at an elevation of 410 m at the Fundación Jatun Sacha , 01°03′57.5″S, 77°37′00.2″W, Napo, Ecuador (Dec. 2, 2009; Niarchos Exped. ), deposited in QCAZ (PBI_OON 51326) .

DIAGNOSIS: Males can be recognized by the prolaterally excavated palpal apophysis ( figs. 482–485 ), females by the relatively short anterior genitalic process, which is sharply narrowed subdistally ( figs. 472, 473 ).

MALE (PBI_OON 51326, figs. 452 , 469 , 474–485 ): Total length 1.10. 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 small lobe bearing modified seta, two other modified setae situated more proximally, one of those jutting out to side of endite. Palpal apophysis prolaterally excavated, embolus and conductor separate; cymbium fused with bulb but with clearly defined seam between.

FEMALE (PBI_OON 51327, figs. 470–473 ): Total length 0.97. Anterior genitalic process relatively short, curvaceous, set in very shallow boat-shaped process.
