  • An Overview of Molecular Odonate Studies, and Our Evolutionary Understanding of Dragonfly and Damselfly (Insecta: Odonata) Behavior
    International Journal of Odonatology Vol. 14, No. 2, June 2011, 137–147 Dragons fly, biologists classify: an overview of molecular odonate studies, and our evolutionary understanding of dragonfly and damselfly (Insecta: Odonata) behavior Elizabeth F. Ballare* and Jessica L. Ware Department of Biological Sciences, Rutgers, The State University of New Jersey, 195 University Ave., Boyden Hall, Newark, NJ, 07102, USA (Received 18 November 2010; final version received 3 April 2011) Among insects, perhaps the most appreciated are those that are esthetically pleasing: few capture the interest of the public as much as vibrantly colored dragonflies and damselflies (Insecta: Odonata). These remarkable insects are also extensively studied. Here, we review the history of odonate systematics, with an emphasis on discrepancies among studies. Over the past century, relationships among Odonata have been reinterpreted many times, using a variety of data from wing vein morphology to DNA. Despite years of study, there has been little consensus about odonate taxonomy. In this review, we compare odonate molecular phylogenetic studies with respect to gene and model selection, optimality criterion, and dataset completeness. These differences are discussed in relation to the evolution of dragonfly behavior. Keywords: Odonata; mitochondrion; nuclear; phylogeny; systematic; dragonfly; damselfly Introduction Why study Odonata? The order Odonata comprises three suborders: Anisozygoptera, Anisoptera, and Zygoptera. There are approximately 6000 species of Odonata described worldwide (Ardila-Garcia & Gregory, 2009). Of the three suborders Anisoptera and Zygoptera are by far the most commonly observed and collected, because there are only two known species of Anisozygoptera under the genus Epiophlebia. All odonate nymphs are aquatic, with a few rare exceptions such as the semi-aquatic Pseudocordulia (Watson, 1983), and adults are usually found near freshwater ponds, marshes, rivers (von Ellenrieder, 2010), streams, and lakes (although some species occur in areas of mild salinity; Corbet, 1999).

  • Taxonomy and Conservation Concerns of the Critically Endangered Roppaneura Beckeri, a Phytotelm-Breeding Damselfly in the Southern Brazilian Atlantic Forest
    Bulletin of Insectology 74 (1): 91-101, 2021 ISSN 1721-8861 eISSN 2283-0332 Taxonomy and conservation concerns of the critically endangered Roppaneura beckeri, a phytotelm-breeding damselfly in the southern Brazilian Atlantic Forest Leonardo POLIZELI1,2, Ângelo Parise PINTO2 1Undergraduate course of Ciências Biológicas, Universidade Federal do Paraná, Curitiba, Paraná, Brazil 2Laboratory of Systematics on Aquatic Insects (LABSIA), Departamento de Zoologia, Universidade Federal do Pa- raná, Curitiba, Paraná, Brazil Abstract Phytotelm-breeding Odonata are rare: from the 6,300 known species of these charismatic freshwater organisms, only a small number of about 50 develop in phytotelmata habitats. Mainly members of the damselflies (suborder Zygoptera) are dependent on this special type of environment. The small coenagrionid Roppaneura beckeri Santos (Odonata Coenagrionidae Protoneurinae), a damselfly endemic to the Brazilian Atlantic Forest, is the only known Odonata breeding in the terrestrial umbellifers of Eryngium floribundum (Cham. et Schltdl.). This is a species-specific association with a hostplant unparalleled in the order. It also is the only species within the subfamily Protoneurinae to occupy phytotelmata habitats. Here, we report on a population of R. beckeri rediscovered after 42 years and recorded for the first time from the southern Atlantic Forest from the state of Paraná. The morphology and the distribution of this species is reviewed and based on these primary data future conservation strategies are discussed. We suggest including R. beckeri as a priority species for dragonfly conservation policies due to its exclusive biological characteristics, evolutionary rele- vance, and occurrence in urban to peri-urban landscapes. Key words: conservation, Plateau Paranaense, Zygoptera, Coenagrionidae, urban insects.

This is not the first book about this order of insects, and the work of Sid Dunkle in Dragonflies Through Binoculars was a great help in assembling and presenting the material. Pat Morton was a great help in reviewing the material and keeping the work on track. Booklet.qxd 11.07.2003 10:59 AM Page 4 INTRODUCTION Background Dragonflies and Damselflies are members of the insect order Odonata, derived from the Greek word odonto meaning tooth. They are insects meaning that they have three body regions — a head, a thorax to which their four wings and six legs are attached and an abdomen. They are characterized by two pairs of net-veined wings and large compound eyes. Their wings are not linked together, allowing each wing to operate independently of the others. Damselflies have narrowly rectangular heads and eyes separated by more than their own width while dragonfly eyes are never separated by more than their own width. Both are preda- tors throughout their lives and valuable in destroying mosquitoes, gnats and other insects though they can become pests near beehives and may take other beneficial insects like butterflies.

These non-iridescent damselflies rest with wings closed over their body. The wings are transparent and rounded at the tip. The long and slender abdomen is slightly longer than the hind wing. Some of the smallest damselflies like the Golden Dartlet (Ischnura aurora) is from this family. Marsh Darts are found throughout the world. World over, this family is represented by about 1147 species. Within Indian limits, 65 species are known and in peninsular India 25 species are recorded. The marsh darts breed in a variety of aquatic habitats like ponds, marshes, streams and Photo:E.Kunhikrishnan rivers. Though most of the species are closely associated with aquatic habitats, some Golden Dartlets mating species like the Common Marsh Dart (Ceriagrion coromandelianum) can be found far away from any aquatic habitat.

  • Prodasineura Doisuthepensis Sp. Nov. from Thailand (Odonata: Protoneuridae)
    ------- Received 29 july 2006; revised and accepted 09 December 2006 ------- Prodasineura doisuthepensis sp. nov. from Thailand (Odonata: Protoneuridae) Rene Hoess Normannenstrasse 35, 3018 Bern, Switzerland. <ReneHoess@1 st.ch> Key words: Odonata, dragonfly, Prodasineura, new species, Southeast Asia, Thailand. ABSTRACT Prodasineura doisuthepensis sp. nov. from Thailand is described and figured. The holotype and two paratypes were collected by the author on 11 May 2002 on the slopes of Doi Suthep, Chiang Mai Province, Thailand (18°48'N, 98°56'E). The material will be deposited at the Naturhistorisches Museum Basel (NHMB). The female is unknown. This is the only known species of the genus with the dor­ sum of the synthorax almost entirely azure-blue. INTRODUCTION The genus Prodasineura is a relatively large one, with about 35 named species dis­ tributed in the Old World tropics from West Africa through India to the Philippines in the east. The greatest species diversity is found at the eastern end of the range in Borneo. The general appearance of the species is fairly uniform, all being similar in size and having a slender black body with pale markings in different colours, espe­ cially on the thorax and at the end of the abdomen. The structure of the cerci in the male and of the posterior margin of the prothorax in the female is fairly similar in all species but shows sufficient variation in details to be useful for interspecific dis­ tinction. So far six species of Prodasineura are known to occur in Thailand (Hamamlainen & Pinratana 1999). One of these, although widespread and described in detail (Asahina 1983), has no name (P.

  • Deciphering the Förster Dragonfly Collection Hadley Samarco, Erika Tucker P.H.D
    Collection Detective: Deciphering the Förster Dragonfly Collection Hadley Samarco, Erika Tucker P.h.D. Fig. 1 Fig.2 Abstract Discussion Friedrich Förster was a german zoologist who traveled the globe In total, 180 specimens were identified from all around the around the turn of the twentieth century collecting hundreds of globe, spanning six different continents and 27 countries. dragonfly and damselfly specimens. After his death, his collection They belonged to six different species: Coenagrionidae, was donated to the University of Michigan for safe keeping, but Platycnemididae, Protoneuridae, Megapodagrionidae, has remained largely unexplored. In an effort to make the Euphaeidae, and Calopterygidae. Of all the dragonflies and collection and associated data accessible, we are digitizing the damselflies imaged, a bit less than half of them had available Forster collection, and using the data to map where he traveled. locations to be plotted on the map. Some of these locations To do this, we are systematically imaging the specimens alongside were vague, for example just identifying the country of their original labels and adding a scannable unique identification origin with no other details. The dragonflies and damselflies code to identify them within the university’s collection. These identified do not represent the entire Förster collection; for a images are then uploaded to a drive where the labels are complete exploration of the collection all specimens would transcribed and entered into an organized spreadsheet. The Results need to be analyzed in a similar manner. specimens are then returned to their collection case with their new Specimens with a known location were put on the map pictured in identification number.
