Aschnaoonops villalba , new species

Figures 579–589

TYPES: Male holotype and female allotype from forest leaf litter taken at an elevation of 3900 feet at a site 6 mi N of Villalba on Rt. 149, 6.7 mi W of Rt. 143, near Cerro de Punta, Villalba, Puerto Rico (Mar. 18, 1992; L. Herman), deposited in AMNH ( PBI_ OON 38066 ) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males can easily be recognized by the pair of parallel, ventrally directed flanges at the base of the embolus (figs. 585– 587); the single known female specimen is probably teratological, but can be recognized by the presence of spines on the prolateral surfaces of tibiae and metatarsi III and IV.

MALE (PBI_OON 38066, figs. 579, 582– 587): Total length 2.03. ALE separated by less than their radius. Sternum surface coarsely reticulate, microsculpture everywhere but front. Endites with anterior process narrow, sharply pointed. 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, r1-1-1; II p0-0-2; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-1p-2; II v3- 0-2. Sperm pore small, narrow, slitlike. Cymbium without distal patch of setae. Embolus as seen in lateral view, with two parallel, ventrally directed prongs.

FEMALE (PBI_OON 38066, figs. 580, 581, 588, 589): Total length 2.35. Dorsal scutum covering more than 3/4 of abdomen length, more than 1/2 to most of abdomen width, fused to epigastric scutum. Postepigastric scutum almost semicircular, covering about 1/2 of abdomen length. Leg spination: femora I, II p0-0-2, r1-1-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-1p-2; II v3-0-2 (tibiae, metatarsi III, IV also have prolateral spines, right and left sides different, specimen probably teratological). No anterior genitalic process detected, only short, translucent basal sclerite (probably teratological).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Puerto Rico.
