ETYMOLOGY: The specific name is a noun in apposition taken from the
type
locality.
DIAGNOSIS: Males can easily be recognized by the shape of multiple embolar projections (figs. 428–430). The females here assigned to the species have not been collected together with males, and may be mismatched; they resemble those of
A. chorro
but have a differently shaped extension on the anterior genitalic process and a sinuous anterior margin of the sclerite at the base of that process (figs. 431, 432).
MALE (PBI_OON 872, figs. 422, 425– 430): Total length 2.31. ALE separated by their radius to diameter. Sternum surface coarsely reticulate, microsculpture everywhere but front. Endites with tip of anterior process directed anterolaterally. Dorsal scutum covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum. Postepigastric scutum long, almost rectangular, extending to nearly full length of abdomen. Leg spination: femora: I p0-0-2, r0-1-1; II p0-0-2; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-1p; II v2- 0-2. Sperm pore small, narrow, slitlike. Cymbium without distal patch of setae. Distal prong of embolus with three processes.
FEMALE (PBI_OON 38041, figs. 423, 424, 431, 432): Total length 3.12. Dorsal scutum covering more than 3/4 of abdomen length, more than 1/2 to most of abdomen width. Postepigastric scutum almost semicircular, covering about 1/3 of abdomen length. Leg spination: femora I, II p0-0-2; r1-1-1; tibiae I, II v4-4-2; metatarsi: I v2-2-2; II v3-0- 2. Anterior genitalic process with spadeshaped anterior extension, sclerite at base with medially invaginated anterior margin.
