Reductoonops tandapi

new species

Reductoonops tandapi   , new species ( figs. 353–372 View FIGURES 353–367 View FIGURES 368–380. 368–372 )

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 View Materials ), plus male paratype, same data, deposited in AMNH (PBI_ OON 49613 View Materials ) GoogleMaps   .

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 View FIGURES 353–367 ); 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 View FIGURES 368–380. 368–372 ). Compared to the sympatric species R. pichincha   , these animals have much larger eyes ( figs. 353, 354 View FIGURES 353–367 , 370 View FIGURES 368–380. 368–372 ), and more widespread sternal setae ( figs. 368, 369 View FIGURES 368–380. 368–372 ).

MALE (PBI_ OON 51317 View Materials , figs. 353–368 View FIGURES 353–367 View FIGURES 368–380. 368–372 ): 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 View Materials , figs. 369–372 View FIGURES 368–380. 368–372 ): 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.
