BOLD: SPIPA603-10.

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

DIAGNOSIS: Males resemble those of the other species from Panama by the general shape of the palp, but can be distinguished by a small lateral projection on base of the embolus in dorsal and lateral view (fig. 37G–I). Females resemble those of O. guatemala by the shape of the anterior receptaculum but can be distinguished by the internal pockets, placed ~45° from the body axis (figs. 39E, 41F).

MALE (PBI_OON 51107): Total length 1.10. Habitus as in figure 32A–D. CEPHALOTHO- RAX: Carapace as in figure 32A, C, D. Sternum as in figure 32B. Labium rectangular. ABDO- MEN: Pale white. LEGS: Only legs II present. GENITALIA: Embolus dark, short, with ventral projection near base; sperm duct spiraled with several loops (fig. 37G–I).

FEMALE (PBI_OON 51107): Total length 1.41. Habitus as in figure 32E–G. CEPHALO- THORAX: Carapace yellow (fig. 32E, G). Sternum yellow (fig. 32F). Chelicerae, endites, labium yellow. ABDOMEN: Pattern of dorsal squares and lateral bands of pale-purple pigment (fig. 32E–G). LEGS: Yellow. GENITA- LIA: Epigastric region without external pockets, internal pockets present, well developed, placed at sides of epigastric fold; ante- rior receptaculum with rounded base, anterior apodemes short; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 39E, 41F, 44F).
