The genus Temnotrogon is possible monotypic taxon with a single species - Hispaniolan trogon
The Hispaniolan trogon (Priotelus roseigaster) is a species of bird in the family Trogonidae. It is endemic to Hispaniola (both Haiti and the Dominican Republic) in the Caribbean. It is one of the only two trogon species found in the Caribbean. It is the national bird of Haiti.
Its natural habitats are subtropical or tropical moist montane forests, and heavily degraded forest. It is threatened by habitat loss. It is mostly confined to a few remaining protected areas. It inhabits rain, dry, pine and broadleaved deciduous forests. Several early records included mangrove swamps west of Miragoane but whether these were visitors or a resident population is unknown. It requires large, old decayed trees with holes for nesting. It primarily occurs at 500–3,000 m, but there appears to be some altitudinal migration with birds observed at lower elevations in winter. In Haiti, it is restricted to the Massif de la Hotte and Chaîne de la Selle, due to extensive habitat loss. It is still quite common in the Dominican Republic, especially in the relatively undisturbed Sierra de Baoruco, although there has been a moderately rapid population reduction, owing to deforestation.
