TYPES: Male holotype and female allotype taken in leaf litter around Altamira, Alrededor Station, Puntarenas, Costa Rica (Aug. 5, 2003; C. Víquez, R. Gutierrez), deposited in INBIO (74344, PBI _OON 26359) .

DIAGNOSIS: Both sexes have relatively large and heavily sclerotized booklung covers (figs. 319, 351); males have an enlarged palpal femur and a relatively wide embolus, narrowed at about four-fifths its length and with a rounded apex (figs. 325–327), and females have a relatively wide anterior epigynal sclerite that fills much of the epigynal atrium (figs. 357–359).

MALE (PBI_OON 26359, figs. 318–349). Total length 1.53. Carapace sides mostly smooth, granulations restricted to lateral margins. Sternum smooth. Endites without anteromedian modifications. Abdomen unpatterned, scuta smooth. Palpal femur greatly expanded; embolus distinctly narrowed distal to sperm duct opening.

FEMALE (PBI_OON 26359, figs. 350–363). Total length 1.67. Anterior epigynal sclerite massive, widened throughout its length; apodemes short, curved dorsally.
