Pantala flavescens is new to the Azores and the Canary Islands. The first record of Ischnura hastata from Graciosa Island confirms the species' breeding in all nine islands of the Azores. The presence of Ischnura senegalensis in the Canary Islands is confirmed. Single specimens of Agriocnemis exilis, Anax rutherfordi, and Anax tristis found in museum collections bring the checklist of Cape Verde to 17 species. No new species have been reported from Madeira or the Savage Islands. In summary, the checklist of Macaronesian Odonata now comprises acknowledged records of 23 species (8 Zygoptera, 15 Anisoptera). 9 Boletín Rola nº 8, segundo semestre 2016 RESUMEN Se actualizan los inventarios de los odonatos detectados en todos los archipiélagos de Macaronesia, basandosé en la literatura publicada posteriormente al estudio de Weihrauch (2011). Desde entonces, se ha detectado Pantala flavescens, nueva en Azores e Islas Canarias. La primera cita de Ischnura hastata en Graciosa ha confirmado su reproducción en las nueve islas de las Azores. La presencia de Ischnura senegalensis fue confirmada en las Islas Canarias. Especímenes únicos de Agriocnemis exilis, Anax rutherfordi y Anax tristis han aparecido en colecciones de museos, elevando el inventario de Cabo Verde a 17 especies. No se han registrado nuevas especies en Madeira e Islas Salvajes. En resumen, el inventario de Macaronesia comprende actualmente 23 especies (8 Zigópteros, 15 Anisópteros). INTRODUCTION Weihrauch (2011) evaluated the then available, published and also a few unpublished records for his comprehensive review of the occurrence and distribution WEIHRAUCH, F. (2011) A of Odonata in the Macaronesian Islands and provided review of the distribution the first detailed checklist for the various Macaronesian of Odonata in the Archipelagos. However, only half a decade later, Macaronesian Islands, with particular reference to the increased knowledge as well as some new, sometimes Ischnura puzzle. Journal of unexpected, records have already altered the checklist. the B.D.S., 27: 28-46. What is more, significant parts of the so-called “Ischnura PEELS, F.

From these papers and others, especially PINHEY (1962a), 99 species ofOdonata have been recorded in Ghana to date.

    BINDURA UNIVERSITY OF SCIENCE EDUCATION AN ASSESSMENT OF INFESTATION BY PARASITIC WATER MITES ON DRAGONFLIES AT A MARSH ALONG MWENJE DAM, MAZOWE DISTRICT, ZIMBABWE BY CHARASHIKA ZAKARIA B1129476 SUPERVISOR: DR. C. PHIRI A DISSERTATION SUBMITTED TO BINDURA UNIVERSITY OF SCIENCE EDUCATION, IN PARTIAL FULFILLMENT OF THE REQUIREMENT FOR THE BACHELOR OF SCIENCE EDUCATION HONOURS DEGREE (BIOLOGY). JUNE 2014 1 ABSTRACT This study was done to determine the infestation levels by water mites (Hydrachnidae) on dragonflies (Anisoptera) that are found at a marsh along Mwenje Dam in Mazowe District, Zimbabwe. A total of 111 dragonflies comprising Aeshnidae (31.5%) and Libellulidae (68.5%) were collected over a period of four months (January to April 2014). The total length and gender of each individual was recorded, as well as number and attachment sites of the parasitic mites. Overall, a total of 28.8% insects were infected. Among the Aeshnidae, the proportion of males that were infected were significantly greater than the females (Chi- square, χ2, p < 0.05). However, for Libellulidae there was no significant difference in the proportions of infected males and females (Chi-square, χ2, p > 0.05). A significantly greater proportion of Aeshnidae was parasitized as compared to Libellulidae (Chi-square, χ2, p < 0.05). For both taxa, the parasites were attached on either the thorax or abdomen, with no significant difference in the number of parasites between the two attachment sites (ANOVA, p > 0.05). 2 ACKNOWLEDGEMENTS I would like to thank my supervisors Dr Phiri and Mr Munosiyei for guidance, encouragement and support during the research period especially when hope was oblique.

  • Dragonflies (Odonata) of Mulanje, Malawi
    IDF-Report 6 (2004): 23-29 23 Dragonflies (Odonata) of Mulanje, Malawi Klaas-Douwe B. Dijkstra Gortestraat 11, NL-2311 MS Leiden, The Netherlands, [email protected] Abstract 65 species of Odonata are recorded from Mulanje and its slopes. Only eight species dominate on the high plateau. Among them are two relict species of conservation concern: The endemic Oreocnemis phoenix (monotypic genus) and the restricted-range species Chlorolestes elegans. The absence of mountain marsh specialists on the plateau is noteworthy. Mulanje’s valleys, of which Likabula and Ruo are best known, have a rich dragonfly fauna. The Eastern Arc relict Nepogomphoides stuhlmanni is common here. Introduction Mulanje, at about 3000 m the highest peak between Kilimanjaro and Drakens- berg, is an isolated massif in Southern Malawi. From a plain at about 700 m altitude it rises almost vertically to a plateau with an average altitude of 2000 m. The plateau (including peaks) has a surface of about 220 km², being approxi- mately 24 km across at its widest point. The plain surrounding the massif was originally dominated by miombo (Brachystegia woodland), but is now largely under cultivation. The valleys are characterised by lowland and submontane forest, the plateau by montane forest, grasslands, bracken fields, scrub and rocky slopes, interspersed with countless streams (Dowsett-Lemaire 1988; Eastwood 1979). Surveys have shown that the Mulanje Massif contains over 30 million metric tonnes of bauxite, with an estimated excavation life of 43 years. In 2001 the government of Malawi announced to take action to exploit these reserves. Bauxite is an erosion mineral, which has been deposited superficially on the plateau.
