Quadratum Selys, with a Key to Theknown Larvae
Odonatologica 38(4): 321-328 December 1, 2009 Description of thelarva of Acanthagrion quadratum Selys, with a key to theknown larvae of the genus (Zygoptera: Coenagrionidae) R. Novelo-Gutiérrez Systematics Network, Institute de Ecología, A.C., Apartado Postal 63, MX-91070 Xalapa,Veracruz, Mexico [email protected] Received 18 August 2009 / Reviewed and Accepted 5 September 2009 The larva is described, illustrated, and compared with other described congeneric larvae. A. quadratumis distinguished from all others by possessing 3 premental setae, 4 setae on labial palp, and caudal lamellae 8-10 times longer than their widest part. A key tothe 9 known congeneric larvae is provided INTRODUCTION The neotropical genus Acanthagrion Selys, 1876 comprises 40 known species ELLENRIEDER & (VON LOZANO, 2008), A. inexpectum Leonard and A. quadratum Selys occur in Mexico (GONZAlEZ-SORIANO & NOVELO-GU- TIERREZ, 2007). The genus was redefined by VON ELLENR1EDER & LOZ- ANO (2008), who diagnosed the larvae from those of Oxyagrion by their markedly lanceolate caudal lamellae, with width/length ratio 0.18 or less, and longer than abdomen (1.02 or more). Despite the speciose nature of the genus, larvae of only eight species (20% of genus) have been described: A. ascendens Calvert (GEIJS- KES, 1941), A. adustum Williamsonand A. indefensum Williamson(GEIJSKES, 1943), A. fluviatile De Marmels (DE MARMELS, 1990), A. apicale Selys (DE MARMELS, 1992), A. hildegarda Gloger (MUZON et al. 2001), A. vidua Selys (DE MARMELS, 2007), and A. aepiolum Tennessen (LOZANO et al., 2007). WESTFALL & MAY (1996) keyed the larva of A. quadratum, providing some but did include figures, not a description. -

A Revised, ANNOTATED Checklist of Victorian Dragonflies (Insecta: Odonata)
A REVISED, ANNOTATED CHECKLIST OF Victorian DRAGONFLIES (Insecta: Odonata) I.D. ENDERS by 56 Looker Road, Montmorency, Victoria 3094, Australia E-mail: [email protected] ENDERS by , I.D. 2010. A revised, annotated checklist of the Victorian dragonflies (Insecta: Odonata). Proceedings of the Royal Society of Victoria. 122(1): 9-27. ISSN 0035-9211. Seventy-six species of Odonata are known from Victoria (26 Zygoptera; 50 Anisoptera). In the last ten years one new species Austroaeschna ingrid Theischinger, 2008 has been described from the State; Austroepigomphus praeruptus (Selys, 1857) and Pseudagrion microcephalum (Rambur, 1842) have now been recorded; and records of Rhadinosticta banksi (Tillyard, 1913) and Labidiosticta vallisi (Fraser, 1955) are judged to be erroneous. Generic names of Aeshna, and Trapezostigma have been changed. Some changes in higher level names and relationships, based on recent phylogenetic analyses, have been incorporated. Distribution maps for all species, based on museum collections, are provided. Key Words: Odonata, Zygoptera, Anisoptera, Victoria, Australia, checklist, Hemiphlebia IN the ten years since an annotated checklist of the molecular study seeks greater taxon and genome Victorian Odonata was published (Endersby 2000), sampling and, as this occurs, slow convergence be- a new species has been described from Victoria, tween the alternatives is appearing. In the meantime additional species have been recorded in the State, some framework is needed on which to list the Vic- substantial museum collection label data have be- torian fauna today. Theischinger & Endersby (2009) come available, and numerous phylogenetic stud- have tried to steer a middle course, avoiding the ex- ies have been published. Theischinger & Endersby tremes but acknowledging that change is occurring; (2009) have incorporated many of these changes into it will still annoy some but must be seen as a work in an identification guide for the adults and larvae of progress. -

The Superfamily Calopterygoidea in South China: Taxonomy and Distribution. Progress Report for 2009 Surveys Zhang Haomiao* *PH D
International Dragonfly Fund - Report 26 (2010): 1-36 1 The Superfamily Calopterygoidea in South China: taxonomy and distribution. Progress Report for 2009 surveys Zhang Haomiao* *PH D student at the Department of Entomology, College of Natural Resources and Environment, South China Agricultural University, Guangzhou 510642, China. Email: [email protected] Introduction Three families in the superfamily Calopterygoidea occur in China, viz. the Calo- pterygidae, Chlorocyphidae and Euphaeidae. They include numerous species that are distributed widely across South China, mainly in streams and upland running waters at moderate altitudes. To date, our knowledge of Chinese spe- cies has remained inadequate: the taxonomy of some genera is unresolved and no attempt has been made to map the distribution of the various species and genera. This project is therefore aimed at providing taxonomic (including on larval morphology), biological, and distributional information on the super- family in South China. In 2009, two series of surveys were conducted to Southwest China-Guizhou and Yunnan Provinces. The two provinces are characterized by karst limestone arranged in steep hills and intermontane basins. The climate is warm and the weather is frequently cloudy and rainy all year. This area is usually regarded as one of biodiversity “hotspot” in China (Xu & Wilkes, 2004). Many interesting species are recorded, the checklist and photos of these sur- veys are reported here. And the progress of the research on the superfamily Calopterygoidea is appended. Methods Odonata were recorded by the specimens collected and identified from pho- tographs. The working team includes only four people, the surveys to South- west China were completed by the author and the photographer, Mr. -

Holistic Survey on Damselfly (Anisoptera : Odonata)Diversity in Rice Ecosystem of Eastern India
International Research Journal of Natural Sciences Vol.4, No.4, pp.19-34, December 2016 ___Published by European Centre for Research Training and Development UK (www.eajournals.org) HOLISTIC SURVEY ON DAMSELFLY (ANISOPTERA : ODONATA)DIVERSITY IN RICE ECOSYSTEM OF EASTERN INDIA C.R. Satpathi and A. Mondal Department of Agricultural Entomology Bidhan Chandra Krishi Viswavidyalaya( State agricultural University), P.O- Mohanpur, Dist. – Nadia, West Bengal -741252, India ABSTRACT: This study highlights the richness of Damselfly (Anisoptera: Odonata) fauna associated with rice ecosystems in Eastern India.. Sampling of the Damselfly community was conducted during 2010-14 to determine species composition, abundance and distribution in 3 different habitats of rice fields which were selected at 60 m (Chakdaha), 600 m (Cooch Behar) and 1250 m (Kalimpong) respectively. Each location was surveyed at a biweekly interval after transplanting of rice plants and about 10 species of Damselfly were recorded as insect predators in rice crops of Eastern India. General morphology, biology, ecology, behavior of the Damselfly are being highlighted in the present investigation. After comparing different body parts, double branching keys are prepared for their easy identification. The studies of their diversity showed that maximum and minimum value of both Simpson and Shannon-Weiner index were at the flowering and the vegetative stage of crop respectively. The value of Margalef index and Menhinck index also indicated that the highest value in reproductive stage of rice crop. The studies on Evenness index designated that the value of E1, E2 and E3 were influenced by species richness and not evenness. Consequently the influence of fertilizer on the incidence of Damselfly in rice ecosystem showed that there was a remarkable increase of population where high doses of nitrogen (120 kg/ha) were applied followed by the use of mix fertilizer(120:60:60 N:P:K). -
2010 Animal Species of Concern
MONTANA NATURAL HERITAGE PROGRAM Animal Species of Concern Species List Last Updated 08/05/2010 219 Species of Concern 86 Potential Species of Concern All Records (no filtering) A program of the University of Montana and Natural Resource Information Systems, Montana State Library Introduction The Montana Natural Heritage Program (MTNHP) serves as the state's information source for animals, plants, and plant communities with a focus on species and communities that are rare, threatened, and/or have declining trends and as a result are at risk or potentially at risk of extirpation in Montana. This report on Montana Animal Species of Concern is produced jointly by the Montana Natural Heritage Program (MTNHP) and Montana Department of Fish, Wildlife, and Parks (MFWP). Montana Animal Species of Concern are native Montana animals that are considered to be "at risk" due to declining population trends, threats to their habitats, and/or restricted distribution. Also included in this report are Potential Animal Species of Concern -- animals for which current, often limited, information suggests potential vulnerability or for which additional data are needed before an accurate status assessment can be made. Over the last 200 years, 5 species with historic breeding ranges in Montana have been extirpated from the state; Woodland Caribou (Rangifer tarandus), Greater Prairie-Chicken (Tympanuchus cupido), Passenger Pigeon (Ectopistes migratorius), Pilose Crayfish (Pacifastacus gambelii), and Rocky Mountain Locust (Melanoplus spretus). Designation as a Montana Animal Species of Concern or Potential Animal Species of Concern is not a statutory or regulatory classification. Instead, these designations provide a basis for resource managers and decision-makers to make proactive decisions regarding species conservation and data collection priorities in order to avoid additional extirpations. -
