A new dragonfly: Libellula coahuiltecana

Dragon flies of the genus Libellula are commonly called skimmers. Most members are from the Northern Hemisphere. These large, wide-bodied dragonflies have wide wings. They spend their time perching on the ground or on vegetation, waiting for insects to fly within range before darting out to capture them.

This new species was found in Mexico and named after the Coahuiltecans, an indigenous group who inhabited the territory of the present day States of Coahuila (where this species was found)and Nuevo León in México and southern Texas in USA.

For the experts: A new species of Libellula is described from specimens collected in the most interesting area of Cuatro Ciénegas, Coahuila, México. Libellula coahuiltecana sp. nov. is similar in color and morphology to L. needhami Westfall with which it co-occurs locally. It differs from the latter by having conspicuous orange spots on base of wings and nodal area, and costal, subcostal, and wing tip areas slightly infumated with the same color. Other differences exist in the morphology of the secondary genitalia of males and the shape of the vulvar plate of female
