Plega variegata Navás, 1928 nomen dubium

The genus Plega was erected based on a single male specimen from Motzorongo (Tezonapa Municipality), Veracruz (Navás 1928), Mexico. According to Ohl (2004) the type specimen was deposited in the Navás Collection, of which a great part was housed in the Museo de Zoología of Barcelona after his death. Unfortunately, most of this collection was severely damaged during the Spanish Civil War, and a great amount of types were lost or destroyed (Monserrat 1985). In the list of types of the Navás Collection deposited at the Museo de Zoología of Barcelona published by Monserrat (1985), the type of P. variegata is not cited. Consequently, this specimen was probably destroyed. Because of insufficient information at this time to unravel the identity of this species, we opted to consider P. variegata as a nomen dubium and not to include it in the present taxonomic key.
