Abstract
Abstract. A new polycentropodid caddisfly species is described from Miocene Dominican amber. The family Polycentropodidae is therefore represented in the Dominican amber with two species belonging to the genus Cernotina: C. pulchra Wichard, 2007, and C. fossilinova sp. nov. The endemic C. danieli Flint & Sykora, 2004, is the only representative of the genus occurring on Hispaniola today and is similar to the two fossil species. On the Caribbean islands altogether six extant species of the genus Cernotina are registered.

The family Polycentropodidae is represented in the Dominican amber with two species belonging to the genus Cernotina: C. pulchra Wichard, 2007, and C. fossilinova sp. nov
The genus Cernotina occurs in the Nearctic and Neotropical biogeographic regions with the greatest diversity in South America (Holzenthal and Calor, 2017); on the island Hispaniola only one endemic species is known: Cernotina danieli Flint & Sykora, 2004
Summary
The inclusion-rich Dominican amber originated in the Miocene on the Caribbean island Hispaniola. An overview of this rich amber lagerstätte was provided by Penney (2010) and Poinar (2010). Studies of amber inclusions up to 2007 have identified 31 fossil caddisfly species belonging to 15 genera in 11 families (Wichard, 2007). Nov., has been added and is described here These two extinct species are related to the extant C. danieli, which is endemically distributed on Hispaniola. The low diversity of the fossil Polycentropodidae found in Dominican amber is in stark contrast to its occurrence in Eocene Baltic amber where polycentropodids are much more common and diverse (Ulmer, 1912; Wichard, 2013)
