hydrophylita lutzimicron emporos shih polaszek hymenoptera trichogrammatidae from taiwan parasitising eggs and phoretic on adults of the damselfly psolodesmus mandarinus mandarinus zygoptera Calopterygidae
PLOS ONE, 2013Co-Authors: Yuan-tung Shih, Chiun-cheng Ko, Andrew PolaszekAbstract:Hydrophylita emporos n. sp. reared from eggs of Psolodesmus mandarinus mandarinus McLachlan (Zygoptera: Calopterygidae) in Taiwan is described. This is the first species of Hydrophylita to be described from the Old World, and the first record of phoresy in the genus. Adult females were observed aggregating at the base of the female damselfly’s abdomen. When the damselfly begins ovipositing, females move to the tip of the abdomen, enter the water and quickly locate eggs for parasitising. The article contains links to video footage of this process.

additions and refinements to the molecular phylogeny of the calopteryginae sl zygoptera Calopterygidae
Odonatologica, 2012Co-Authors: Zhaoying Guan, Andy Vierstraete, Henri J DumontAbstract:Of 8 previously unstudied calopterygine taxa, the ITS 1 and 2 was sequenced and inserted into a pre-existing phylogenetic tree of all Eurasian and American genera. ITS is mainly appropriate for looking at shallow phylogenetic relationships, and resolved the relationship within and between genera best, with weak support for relationships at the subfamily level. Thus, Atrocalopreryx-Matrona was found to be a complex but very robust clade, while Vestal is s.l. was confirmed to consist of 2 distinct genera. The generic versus specific or subspecific status of few other taxa is discussed. Within Mnais and Vestalis, the position was tested of 2 suspected "aberrant" members, M. gregoryi and V. beryllae. Both were confirmed to belong to the genera to which they had been traditionally assigned.

a revised molecular phylogeny of the calopteryginae zygoptera Calopterygidae
Odonatologica, 2007Co-Authors: Henri J Dumont, Andy Vierstraete, Jacques R. VanfleterenAbstract:An updated version of an ITS-based phylogeny of the Calopteryginae, using sequences of 31 ingroup taxa, is given. The subfamily consists of 3 main clades, each with 2 subclades. Only clade 1 (Calopteryx s. s.) is not exclusively Asian but extends to Europe and North America. In the East-Asian Glade 2, the genus Matrona is found to be descended from an Atrocalopteryx-like ancestor. Several so-called South-East Asian Calopteryx probably either belong to Atrocalopteryx or to as yet unnamed genera near Atrocalopteryx. Archineura consists of 2 spp., limited to China and Indo-China, and is rather basal to clade 3. The subclade Neurobasis-Matronoides is worthy of further analysis.

phylogenetic relationships divergence time estimation and global biogeographic patterns of calopterygoid damselflies odonata zygoptera inferred from ribosomal dna sequences
Systematic Biology, 2005Co-Authors: Henri J Dumont, Jacques R. Vanfleteren, Johan F De Jonckheere, Peter H H WeekersAbstract:The calopterygoid superfamily (Calopterygidae + Hetaerinidae) is composed of more than twenty genera in two families: the Calopterygidae (at least 17) and the Hetaerinidae (at least 4). Here, 62 calopterygoid (ingroup) taxa representing 18 genera and 15 outgroup taxa are subjected to phylogenetic analysis using the ribosomal 18S and 5.8S genes and internal transcribed spacers (ITS1, ITS2). The five other families of calopterid affinity (Polythoridae, Dicteriadidae, Amphipterygidae, Euphaeidae, and Chlorocyphidae) are included in the outgroup. For phylogenetic inference, we applied maximum parsimony, maximum likelihood, and the Bayesian inference methods. A molecular phylogeny combined with a geographic analysis produced a well-supported phylogenetic hypothesis that partly confirms the traditional taxonomy and describes distributional patterns. A monophyletic origin of the calopterygoids emerges, revealing the Hetaerinid clade as sister group to the Calopterygidae sensu strictu. Within Calopterygidae, seven clades of subfamily rank are recognized. Phylogenetic dating was performed with semiparametric rate smoothing by penalized likelihood, using seven reference fossils for calibration. Divergence time based on the ribosomal genes and spacers and fossil constraints indicate that Calopteryginae (10 genera, approximately 50% of all Calopterygid taxa studied here), Vestalinae (1 genus), and Hetaerinidae (1 genus out of 4 studied here) started radiating around 65 Mya (K/T boundary). The South American Iridictyon (without distinctive morphology except for wing venation) and Southeast Asian Noguchiphaea (with distinctive morphology) are older (about 86 My) and may be survivors of old clades with a Gondwanian range that went extinct at the K/T boundary. The same reasoning (and an even older age, ca. 150 My) applies to the amphipterygids Rimanella and Pentaphlebia (South America-Africa). The extant Calopterygidae show particular species and genus richness between west China and Japan, with genera originating between the early Oligocene and Pleistocene. Much of that richness probably extended much wider in preglacial times. The Holarctic Calopteryx, of Miocene age, was deeply affected by the climatic cooling of the Pliocene and by the Pleistocene glaciations. Its North American and Japanese representatives are of Miocene and Pliocene age, respectively, but its impoverished Euro-Siberian taxa are late Pliocene-Pleistocene, showing reinvasion, speciation, and introgression events. The five other calopterid families combine with the Calopterygidae and Hetaerinidae to form the monophyletic cohort Caloptera, with Polythoridae, Dicteriadidae, and Amphipterygidae sister group to Calopterygoidea. The crown node age of the latter three families has an age of about 157 My, but the Dicteriadidae and Polythoridae themselves are of Eocene age, and the same is true for the Euphaeidae and Chlorocyphidae. The cohort Caloptera itself, with about 197 My of age, goes back to the early Jurassic.
