Reductoonops yasuni , new species ( figs. 1–96 )

TYPES: Male holotype from leaf litter taken at an elevation of 200 m in the Estación Científica Yasuni , Río Tiputini, 0.67111°S, 76.4002°W, Orellana, Ecuador (Dec. 1, 2009; Niarchos Exped. ), deposited in QCAZ (PBI_OON 892) .

DIAGNOSIS: Males can be recognized by the bipartite conductor ( figs. 35–38 ), females by the spear-shaped tip of the anterior genitalic process ( figs. 53, 54 ).

MALE (PBI_OON 891, figs. 1–44, 46–51 ): Total length 0.84. Surface of elevated portion of pars cephalica smooth. Eyes two; ALE touching. Sternum with anterior channels, surface finely striated, without pits, microsculpture absent; setae densest laterally. Labium anterior margin deeply incised. Endite tip with rounded, posteriorly directed lobe. Cymbium not fused with bulb.

FEMALE (PBI_OON 891, figs. 45, 52–96 ): Total length 1.13. Anterior genitalic process long, relatively wide, originating from bowl-shaped sclerite.
