Abstract


Chironomidae (Diptera) are among the most diverse and widespread aquatic insects, with roughly 5,500 described species. However, prior to the present work, no species of Chironomidae had been documented from the island of Hispaniola. Collections of non-biting midges, with emphasis on the lotic fauna, were made in the Dominican Republic during July of 2015. In total, 578 specimens belonging to 27 genera and at least 44 species within the subfamilies Chironominae (20 taxa), Orthocladiinae (16 taxa) and Tanypodinae (8 taxa) were found. The subfamilies Chironominae and Orthocladiinae predominated. Polypedilum was the most widespread and diverse genus of Chironominae. Metriocnemus were collected in bromeliad tanks. The chironomid fauna in Dominican Republic includes multiple genera with worldwide distributions, including Holarctic and Neotropical components.
