TYPES: Male holotype and female paratype from Venezuela: Aragua: Maracay, Rancho Grande, 1200 m, 10.40167°, -67.58500°, Dec. 20, 1954, A. Nadler, deposited in AMNH, PBI_ OON 1665.

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

DIAGNOSIS: Males can be distinguished by the presence of a rounded projection near base of the embolus (figs. 59G–I, 63K, L), females by the shape of the tip of the anterior receptaculum, with highly sclerotized base, and by the shape and position of the internal pockets, nearly parallel to the body axis (figs. 60E, 61F, 64C).

MALE (PBI_OON 1665): CEPHALOTHO- RAX: Carapace length 0.61; orange. Clypeus slightly sloping forward. Sternum as long as wide. Chelicerae anterior face with basal conical projections. Labium rectangular. ABDOMEN: Separated from prosoma, pale white. LEGS: Unfortunately, legs are separated in both sexes and mixed in the same vial. They have no spines, fourth femur swollen, two tarsal claws. GENITA- LIA: Embolus short, with rounded projection near base; sperm duct coiled with several loops (figs. 59G–I, 63K, L).

FEMALE (PBI_OON 1665): CEPHALOTHO- RAX: Carapace length 0.62. GENITALIA: External pockets absent, internal pockets almost parallel to each other; anterior receptaculum more sclerotized at base, slightly forked in apical region; posterior receptaculum present, posterior apodeme formed by entire plate (figs. 60E, 61F, 64C).

DISTRIBUTION: Known only from the type locality in Venezuela (Aragua, map 7).

OTHER MATERIAL EXAMINED: None.
