description: Aschnaoonops cosanga, new species
Figures 242–252
TYPE: Female holotype taken in montane evergreen forest litter at an elev. of 2150 m at a site 2.5 km W of Cosanga, 0 ° 35'24"S, 77 ° 53'19"W, Napo, Ecuador (Nov. 5, 1999; R. Anderson), deposited in AMNH (PBI_ OON 823).
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
DIAGNOSIS: Females have a short postepigastric scutum and an anteriorly narrow anterior genitalic process (figs. 243, 252); the single male here tentatively assigned to the species resembles that of A. silvae but has a retrolaterally flatter embolar base (figs. 248– 250).
MALE (PBI_OON 835, figs. 242, 245– 250): Total length 1.85. ALE separated by less than their radius. Sternum surface coarsely reticulate, microsculpture everywhere but front. Anterior part of endites with narrow, triangular projection. Dorsal scutum covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum. Postepigastric scutum long, semicircular, extending to nearly full length of abdomen. Leg spination: femur I p0-0-2, r1-1-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-1p; II v2-2-0. Sperm pore small, circular. Cymbium with distal patch of setae. Embolus with translucent median prong between dark proximal and distal prongs.
FEMALE (PBI_OON 823, figs. 243, 244, 251, 252): Total length 2.11. Dorsal scutum covering 1/2 to 3/4 of abdomen length, more than 1/2 to most of abdomen width, fused to epigastric scutum. Postepigastric scutum short, covering about 1/3 of abdomen length. Leg spination: femora: I p0-0-2, r0-1-1; II p0- 0-2, r0-1-0; tibiae I, II v4-4-2; metatarsi: I v2- 2-1p; II v2-2-0. Anterior genitalic process relatively short, wide.
