TYPES: Male holotype from Costa Rica: Heredia, Estación Biológica La Selva , in Carapa guianensis , 50–150 m, 10.433333°, -84.016667°, Mar. 05, 1993, collector not provided, deposited in INBIO 1230859, PBI_OON 27936 ; same data, in Conceveiba pleiostemona , one female paratype, deposited in INBIO 1227995, PBI_OON 27935 ; same data, in Virola koschnyi, Jan. 14, 1993, one female paratype deposited in INBIO 1225068, PBI_OON 27943 .

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

DIAGNOSIS: Males can be distinguished by the short embolus with flat, sclerotized projection in prolateral view (fig. 36G). Females can easily be distinguished by having two adjacent external pockets on the median line of the epigastric region (figs. 40C, 44H).

MALE (PBI_OON 27936): Total length 1.00. Habitus as in figure 30A–C. CEPHALOTHO- RAX: Carapace as in figure 30A–C. Chelicerae anterior face unmodified but provided with group of dark, needlelike setae, slightly thicker than others (fig. 30C). Labium rectangular.

ABDOMEN: Pale orange. LEGS: Patella plus tibia I shorter than carapace. GENITALIA: Cymbium yellow, bulb stout, tapering apically; embolus dark, short, with flat, sclerotized projection on prolateral side; sperm duct coiled, with few loops (figs. 36G–I, 42G, H).

FEMALE (PBI_OON 27943): Total length 1.00. Habitus as in figure 30D, E. Chelicerae anterior face with needlelike setae. GENITALIA: Epigastric region with two adjacent pockets on median line; anterior receptaculum straight with wide anterior tip; posterior receptaculum present, posterior apodeme formed by entire plate (figs. 40C, 44H).
