TYPES: Male holotype from Panama: Chiriqui: Reserva Forestal Fortuna, Quebrada Honda , 1 hectare PANCODING Inventory , 1135 m, 8.75000°, -82.23889°, June 7–12, 2007, M. Arnedo, D. Dimitrov, G. Hormiga, F. Labarque, M. Ramírez, deposited in MIUP, PBI_OON 42286, PANCODING: SFU1N7R030, barcoding: PA897 ; same data, 1 female paratype deposited in MACN-Ar 29889, PBI_OON 42305, PAN-

CODING: SFB1D9H029, barcoding: PA895.

ETYMOLOGY: The specific name is a patronym in honor of Facundo Labarque, colleague and collector of the type specimen and other species from Panama.

DIAGNOSIS: Males resemble those of O. campana by the general shape of the copulatory bulb, but in O. labarquei the embolic region is wider in lateral view (fig. 38A–C). Females resemble those of O. campana , O. truncata , and O. cali by the general shape of genitalia, but can be distinguished by subtle details of the anterior receptaculum tip shape, larger than in the other species; the lateral projections, and internal pockets (figs. 40B, 41D, 44G).

MALE (PBI_OON 42286): Total length 1.20 (taken from paratype PBI_OON 42319). Habitus as in figure 33A–C. CEPHALOTHORAX: Carapace as in figure 33A, B. Sternum as in figure 33C. Labium rectangular. ABDOMEN: Pale white. GENITALIA: Embolus dark, short, with claw-shaped projection seen in prolateral view; sperm duct slightly coiled, with several loops (fig. 38A–C).

FEMALE (PBI_OON 42304): Total length 1.25 (taken from paratype PBI_OON 42322). Habitus as in figure 33D–F. ABDOMEN: Dorsum, sides, venter soft portions with pale-purple bands.

GENITALIA: External pockets absent, internal pockets present, small, placed at margins of epigastric fold; anterior receptaculum with massive, rounded-lateral projections, anterior tip wide, with long anterior apodemes, almost hidden by these projections; posterior receptaculum absent,

posterior apodeme formed by entire plate (figs. 40B, 41D, 44G).

DISTRIBUTION: Known from the provinces of Chiriqui and Cocle in Panama (map 4).
