description: Aschnaoonops yasuni, new species
Figures 219–230
TYPE: Male holotype from a Berlese sample of humid forest litter taken at an elevation of 295 m at the Estacio´ n Científica Yasuní, 0.067428 ° S, 76.39764 ° W, Orellana, Ecuador (Dec. 1–5, 2009; M. Ramírez, Niarchos Exped.), deposited in QCAZ (PBI_OON 826).
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
DIAGNOSIS: Both sexes can easily be recognized by the protrusions at the posterolateral corners of the carapace and the sharp denticles on the lateral margins of the carapace (fig. 219), features shared only with the Colombian species A. orito. Males of A. orito are unknown, but females of A. yasuni have the anterior genitalic process widened both anteriorly and posteriorly (fig. 230).
MALE (PBI_OON 826, figs. 219, 220, 222–227): Total length 2.24. ALE separated by less than their radius. Sternum surface coarsely reticulate, microsculpture everywhere but front. Anterior portion of endites with triangular, heavily sclerotized ventral process not reaching as far distally as more dorsal, less heavily sclerotized tip. Dorsal scutum covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum. Postepigastric scutum long, semicircular, extending nearly full length of abdomen. Leg spination: femora: I p0-0-2, r0-1-1; II p0-0-1, r0-1-0; tibiae: I v4-4- 2; II v4-4-1p; metatarsi: I v2-2-2; II v2-2- 1p. Sperm pore large, narrow, slitlike. Cymbium with distal patch of setae. Embolus with distal prong more heavily sclerotized than proximal prong.
FEMALE (PBI_OON 827, figs. 221, 228– 230): Total length 2.96. ALE separated by their radius to diameter. Postepigastric scutum almost semicircular, extending to about 2/3 of abdomen length. Leg spination: femora I, II p0-0-2, r0-1-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi I, II v2-2-2. Anterior genitalic process relatively wide, expanded anteriorly.
