Pipunculidae (Diptera) from the caldera de taburiente national park, la palma (canary islands, spain) — investigating the morphological and molecular variability in a new species of big-headed flies

espanolEste trabajo es el resultado del proyecto “Inventario y estudio de la fauna invertebrada del Parque Nacional de la Caldera de Taburiente” en la isla de La Palma, Islas Canarias. De las cuatro especies recogidas, se describe Chalarus guanche sp. nov. que se registra asimismo de Madeira, y Tomosvaryella freidbergi De Meyer, 1995 y T. parakuthyi De Meyer, 1995 son nuevos registros para La Palma. Se estudia la variabilidad morfologica y molecular de C. guanche sp. nov. y se discute la presencia de variacion intragenomica en el ADNr ITS2. EnglishThe present paper is a result of the project “Inventory and study of the invertebrate fauna of the Caldera de Taburiente National Park on La Palma, Canary Islands. Among the four species of Pipunculidae recorded, Chalarus guanche Kehlmaier sp. nov. is described and also recorded from Madeira, whereas Tomosvaryella freidbergi De Meyer, 1995 and T. parakuthyi De Meyer, 1995 are first records for La Palma. The morphological and molecular variability of C. guanche sp. nov. is studied and the presence of intragenomic variation in ITS2 rDNA is discussed.
