CHIRONOMIDAE (INSECTA: DIPTERA) OF SAN SALVADOR ISLAND, BAHAMAS: ENHANCING KNOWLEDGE OF NEOTROPICAL BIODIVERSITY
The Chironomidae (Diptera), commonly known as non-biting midges, are a species-rich family of holometabolous insects that live out their immature stages in aquatic habitats. Following emergence of the adult, the pupal exuviae (cast pupal skin) remains floating on the water’s surface. Pupal exuviae are species-specific, allowing identification to species, and thereby, providing a means to use them in biodiversity assessments. While this family is very diverse, with approximately 5,500 described species worldwide, knowledge of Neotropical species is lacking. Approximately 900 species are known to this ecoregion and only 16 species are known from the Bahamas. Our goal is to enhance the knowledge of Chironomidae of the Bahamas, specifically focusing on those from San Salvador Island. Chironomidae pupal exuviae were collected from various aquatic habitats, including rock pools and intermittent ponds, on San Salvador in June 2013 and were compared to a similar study from March 2012. Cumulatively, twenty-nine specimens were found, with representatives from 12 morphospecies and 9 genera.; Chironomus was the most common genus; this genus is tolerant of various environmental conditions, matching San Salvador’s relatively harsh environment. Ultimately, these results enhance knowledge of chironomid diversity in the Neotropics.
