Data-rich description of a new genus of praying mantid egg parasitoids, Lasallegrion gen. n. (Hymenoptera: Torymidae: Podagrionini), with a re-examination of Podagrion species of Australia and New Caledonia
Abstract
The genusLasallegriongen. n.is described, and three species,Lasallegrion koebelei(Crawford1912),comb. n.,Lasallegrion virescens(Strand1911),comb. n., andLasallegrion washingtoni(Girault1915),comb. n., are redescribed and transferred to it.Podagrion holbeiniGirault 1923,syn. n., andPodagrion metatarsumGirault 1929,syn. n., are synonymised here withLasallegrion koebelei. Further, 14 species from Australia and New Caledonia are confirmed as belonging toPodagrionSpinola, 1811.
The classic morphological approaches are combined with multivariate ratio analysis and molecular and additional morphological methods for (re-)descriptions. A comprehensive set of morphometric data, COI barcode sequences, a fully sequenced transcriptome and detailed mu CT data are provided.
An updated key to the Australasian genera of Podagrionini and to theLasallegrionspecies is given. Additionally, we present some discussion on the collisions of the concepts of modern taxonomy, and the restrictions caused by poorly conditioned old type material.
