Thrips are small, cosmopolitan insects directly or indirectly associated with plants. Records of these associations in the neotropics add greatly to better understanding of Thysanoptera, not the least because some thrips species are economically important in agriculture and amenity plantings. In this paper we report new plant associations of Franklinothrips vespiformis (Crawford), Gastrothrips sp. Hood, Haplothrips gowdeyi Franklin, Leptothrips astutus Johansen, Leptothrips obesus Johansen, Liothrips spp. Uzel, Torvothrips martinezi Johansen, Arorathrips mexicanus Crawford, Caliothrips fasciapennis (Hinds), Caliothrips nanus (Hood), Caliothrips punctipennis (Hood), Echinothrips caribbeanus Hood, Echinothrips selaginellae Mound, Frankliniella cephalica Crawford, Frankliniella standleyana Hood, Hoodothripiella ignacio Retana-Salazar, Microcephalothrips abdominalis (Crawford) and Retanathrips silvestris (Hood). Some records of the presence of thrips species are new for Costa Rica and Central America.
