FEMALE (PBI_OON 379, figs. 410–417): Total length 1.80. Anterior genitalic projection long, narrow, posterior portion with triangular median receptaculum extending posterior of procurved rim.

Hortoonops excavatus , new species

Figures 418–425

TYPES: Male holotype and female allotype from forest litter taken at an elevation of 800 m at the Salto Jimenoa, 7 km SE of Jarabacoa, La Vega, Dominican Republic, Hispaniola (July 31, 1995; S., J. Peck), deposited in AMNH (PBI_ OON 21094 ) .

ETYMOLOGY: The specific name refers to the excavations on the anterior metatarsi.

DIAGNOSIS: Males can be recognized by the C-shaped tip of the embolus (figs. 419, 421), females by the basally narrow anterior genitalic projection (figs. 424, 425). The distinct abdominal pattern found in the male (fig. 418) is not detectable in the female taken with it (fig. 420). MALE (PBI_ OON 21094 , figs. 418, 419, 421, 422): Total length 1.38. Carapace and sternum not scanned. Abdomen with strong dark pigment patches visible through cuticle on dorsum, sides, venter. Embolus with distal portion C-shaped.

FEMALE (PBI_ OON 21094 , figs. 420, 423–425): Total length 1.51. Abdomen with no pigment patches visible through cuticle. Dorsal view: anterior genitalic projection very long, narrow, situated on very short base.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Hispaniola ( Dominican Republic).
