Description of the male of Megalava truncata Perrichot (Hymenoptera: Megalyridae) in Early Cretaceous amber from El Soplao (Spain).

Abstract : A new fossil of megalyrid wasp recently discovered in Early Cretaceous (Albian) amber from El Soplao (Cantabria, Spain) is described as the male of Megalava truncata Perrichot, 2009, originally described from Peñacerrada I (= Moraza) amber (Burgos, Spain). The new specimen permits a more thorough description of the genus Megalava, which was established originally from a single, fragmentary specimen lacking the metasoma, and also permits a discussion on the characters of phylogenetic value for the clade [Megazar + Megalava].
