O. ruginodis is known to occupy coastal areas in South Florida (Deyrup et al. 1985). I have made the following collections of ruginodis in Costa Rica:
Heredia: La Selva: Collected under epiphyte mat in treefall. Tree down, long-since leafless, but trunk and branches still above surrounding veg., scattered moss/epiphyte clumps still intact.
Limon: Hitoy Cerere: Primary wet forest. Nesting in rotten log.
Limon: 25km NW Cahuita: Coconut strand along beach edge.
Puntarenas: Corcovado, San Pedrillo: foragers on ground at beach edge.
Puntarenas: Corcovado, Sirena: clearing near beach. A colony was in a bed of closely-packed plant cuttings. There were wide, flat-bottomed chambers 2cm below the soil surface in a plastic bag full of potting soil. There was a short cone built on the surface of the soil. Cavities between the bases of adjacent bags contained pupae and tending adults.
Puntarenas: Corcovado, Llorona: collecting on one of the rock islands offshore, separated from land even at low tide, vegetated on top.
West Indies, USA (Florida), Costa Rica. Costa Rica: coastal lowlands of the Atlantic coast and Osa Peninsula; La Selva; Hitoy Cerere (100m).
