Orchestina truncata Wunderlich, 2004a: 1854 , figs. 5–6 (male holotype in copal from Colombia and two separated pieces of copal, from Peña Blanca, Santander province, Colombia (ca. 5.94755°, -73.64110°), deposited in SGN; not examined).

NOTE: We have tentatively included the following specimens under O. truncata , a subfossil spe- cies described from a male from Colombia. The specimens treated here are very similar in male palp morphology to the type as illustrated by Wunderlich (2004a); we consider that the small differences are insufficient to justify describing a new species. Among the examined specimens there is a single male from Quindío, Colombia, which is very close to the type locality, although most of the specimens are from Costa Rica. We have received an image of the label belonging to the holotype with the following inscription: F1113/CC/AR/OON/C 7W. We provide a full description of male and female. A further, detailed analysis of the type material by micro-CT scanning may confirm this assignation.

DIAGNOSIS: Males can easily be distinguished by the shape of the pedipalp, characterized by a small femur, patella attached to the tibia subbasally, tibia swollen, and copulatory bulb stout, almost the same width as the tibia with short embolus (fig. 37A–C). Females resemble those of some species from Panama and O. cali from Colombia by the general shape of the genitalia, with internal pockets and anterior receptaculum with massive lateral projections. However, in O. truncata the internal pockets are more parallel to each other (figs. 39F, 41C, 44E), and the tip of

the anterior receptaculum is slightly different in O. cali and in all the Panamanian species.

MALE (PBI_OON 31129): Total length 1.10. Habitus as in figure 29A–C. CEPHALOTHO- RAX: Sternum wider than long. Labium rectangular. ABDOMEN: Pale grey. LEGS: Spination, metatarsi: III, IV d0-0-2. GENITALIA: Femur sinuous, patella attached to tibia subbasally; embolus dark, short; sperm duct highly spiraled, with many loops (figs. 37A–C, 42C, D).

FEMALE (PBI_OON 27986): Total length 1.35. Habitus as in figure 29D–F. CEPHALOTHORAX: Sternum as long as wide. ABDOMEN: Dorsum, sides, venter soft portions with patches of purple pigment (fig. 29D–F). GENITALIA: Besides diagnostic characters, external pockets absent; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 39F, 41C, 44E).

DISTRIBUTION: Known from Costa Rica, Colombia, and Ecuador (map 3).
