ETYMOLOGY: The specific name is a noun in apposition taken from the
type
locality.
DIAGNOSIS: Males can be distinguished by the combination of the following characters: clypeus rebordered (fig. 89C), chelicerae directed backward, anterior face with basal conical projections (fig. 89B), copulatory bulb with additional apophysis forming a nearly V-shaped structure with the embolus in dorsal view (fig. 97D–F). Females can easily be distinguished by the presence of two external pockets that converge on the median field (fig. 111B) and by the wide anterior tip of the anterior receptaculum.
MALE (PBI_OON 43369): Total length 1.04. Habitus as in figure 89A. CEPHALOTHORAX: Carapace as in figure 89B, orange. Clypeus vertical in lateral view, rebordered (fig. 89B, C). Sternum as long as wide (fig. 89D). Chelicerae directed posteriorly, anterior face with basal blunt projections (fig. 89B). Labium rectangular, with sclerotized margins (fig. 89D). ABDOMEN: Pale white. LEGS: Only left legs I–II are present.
GENITALIA: Bulb with apophysis of almost same length as embolus; sperm duct coiled with many loops (fig. 97D–F).
FEMALE (PBI_OON 50047): CEPHALOTHO- RAX: Carapace length 0.60. ABDOMEN: Ovoid (separated from prosoma). LEGS: Missing. GEN-
ITALIA
: External pockets converging on median field, internal pockets absent, anterior receptaculum with wide tip; posterior receptaculum present, posterior apodeme formed by entire plate (fig. 111B).
DISTRIBUTION: Known only from the
type
locality in

(
