  • Two new beetles from summit forests in the Lesser Antilles
    Two newly discovered species of beetles from the mountaintops of St. Kitts and Nevis have been named for a famous Nevisian scientist and a recently departed Kittitian civil servant.

    DuPorte’s Ground Beetle (Platynus duportei Liebherr and Ivie) and Racquel’s Ground Beetle (Platynus racquelae Liebherr and Ivie) were named to honor the McGill University (Montreal, Canada) insect morphologist Professor Ernest Melville DuPorte (1891–1981), born in Nevis, and Racquel Williams-Ezquea (1983–2018), recently of The Government of the Federation of St Kitts and Nevis’ Forestry Unit.

    Professors James Liebherr of Cornell University and Michael Ivie of Montana State University described the new species in the March, 2021, issue of the international journal Coleopterists Bulletin. The two species occupy the northernmost geographic limit of a species group of Carabidae that is distributed throughout the Lesser Antillean island chain, with their relatives in South America. They are both restricted to the uppermost remnant montane forests on their respective islands, and enhance our biological knowledge of this critically endangered habitat.
