The Odonatafàuna consists of separatewing relîains, preservedas colllpl'essionsin fìne-grained,biturninotts malls, exposedin twcl f-ossilifèroussections developed along the Adriatic coast, in thelower part of a cliff about3 kpr north-westof Pesaro(Marches, Central ltaly) and includedin the Gessoso-solfìfèraFonnation of Lower Messinianage. Most of the dragonflies "strato havebeen discovered by thesenior author in the degliinsetti" (Gt'NltltNt, I 9tì9.1992" I 993:B,qc;Lr & Gr,NrrL-rNr,2003 ), a well celîerìtedinsect bed about 140 17 mm thick, locatednear the top of the Formationand consistingof very thin, dark- greyand light-grey evaporitic laminae probably related to a seasonaldeposition. In this layer severalinsect orders have beendiscovered, often associatedwith fish and leaf remains.These fossil assemblagesmay indicateboth deepoff-shore and shallow,near-shore paleoenvironments: the presenceof varved shalesnormally occurringin quiet basins,the predominanceof articulatedfish remainsand com- plete insectspreserved as adults(especially Hemiptera-Homoptera, Diptera Bibionidae,Mycetophilidae, Limoniidae and insectswith strongflying ability as Diptera Syrphidae,Hymenoptera and Odonata),may indicatea relatively deep- water/ofÈshorepaleoenvironment, while abundantremains of evergreenneedles and taxodiaceousleaves and the presenceof insectswith weak flying ability (Coleoptera,Trichoptera, terrestrial Hemiptera), may representa near-shore paleoenvironment(WrsoN, 1980).Moreover, the scarcityof marinetaxa among "strato theichthyofauna of the degliinsetti"( only few specimensof Latessp. and Harengula sp. have been found) and the predominanceof the hypereuryhaline speciesAphanius crassicaudus (Agassiz,l832), indicate highly salinewater conditions(SonsrNr,l988), with a normalsalinity marine environment, present at leastin cerlainperiods.The majority of the terrestrialplant assemblages collected in this insectbed, suggestvegetational belts characterizedbya greatdiversity of habitatswith the presenceof Thxodiumin the warm, humid and swampycoastal plains,a belt of thermophyleplants with prevailing Quercus,Acer, Populus and probablemountain slopes with predominanceof xerophileforests of Pinus,Sequoia and Thuja. However,the occurrenceof DipteraTrichoceridae in the insect assemblagesand the high proportionof Nearcticand Palearctic genera among the Odonatafauna, rnight suggest also climatic fluctuations including a possiblecooling phase,correlated with the salinitycrisis in the MediterraneanSea during the Late Miocene,with a vegetationalbelt of coniferslowered towards the depositional basin(BenrolaNr MnncHErrr & MnnrorrrLrrer, 1989); anyway, further collecting and comparativestudy will increaseour knowledgeof this Lower Messinian paleoenvironment. F-ossilAnisoptera(adults and larvae) from MonteCastellaro are relatively common, while fossil Zygopteraareextremely rare: only eightspecimens ( about3.5oA of the total numberof Odonata)have been found up to now. It is interestingto note that speciesbelonging to the subfamilyIschnurinae ( OdonataCoenagrionidae) and the family Calopterygidaeare infrequent in Tertiaryinsect localities and only one recordof the genusIschnura is known from the Eocene/Mioceneamber inclusionsof the DominicanRepublic; on the contrary,the familiesLestidae and Sieblosiidaeare well known from Cenozoicdeposits. Moreover, the finding of the generaDeielia and Trapezostigma(Odonata Libellulidae) is also of considerable interest:the wing of Deielia discoveredat Monte Castellaro,represents the first fossil recordof this genus,while well preservedspecies belonging to the genus Trapezostigmaare poorly known from EuropeanNeogene deposits. Fortunately,a Nature Reserve(Parco Naturale di Monte San Bartolo, including 18 the Monte Castellarooutcrop, considered as insectsdeposit of exceptional preservation), was establishedin 1994and now the protectedarea -uy b. used for research, educationand orgamzedvisits.

    nature needs more explorers What sixty new dragonfly and damselfly species from Africa can say about the state of our most critical resource and the exploration of life. Klaas-Douwe B. Dijkstra, Jens Kipping & Nicolas Mézière (1 December 2015) Sixty new dragonfly and damselfly species from Africa (Odonata). Odonatologica 44: 447-678 By naming 60 new dragonflies at once, we want to show that a biologist’s greatest importance today is to provide the names and knowledge needed to add all life to the human conscience. We do so by challenging three common misconceptions about biodiversity: 1. that most of Earth’s species are known to us 2. that the remaining unknown species are hidden and detectable only by genetics 3. that enough effort is being made in the field to uncover the unknown in time We demonstrate this with some of the most sensitive and beautiful of all biodiversity: 1. freshwater — Earth’s most dense and threatened species richness 2. Africa — the continent that will change most in the 21st century 3. dragonflies — the insects that could The new Sarep Sprite Pseudagrion sarepi was named be the best gauge of global change after the SAREP expedition to eastern Angola. Mankind knows just 20% of the 9 million species of animal, plant, fungus and protist thought to inhabit our planet. With 6000 species named, dragonflies and damselflies were regarded as well-known. The 60 new dragonflies described now are the most to be named at once in a century, adding 1 species to every 12 known in Africa. Their beauty and sensitivity can raise awareness for freshwater biodiversity, the densest and most threatened on earth.

Dragonfly, damselfly, Anisoptera, Zygoptera, biodiversity, survey Introduction The mountains of the East African Rift, stretching south from Ethiopia to Mozam- bique, are known to harbour a rich biological diversity owing to their unique habi- tats and long periods of isolation. Typically comprised of evergreen montane forests interspersed with high altitude grassland/moorland habitats, these montane archi- pelagos, often volcanic in origin, have been widely documented as supporting high levels of endemism across taxonomic groups and are of international conservation value (Myers et al. 2000).

Wasscherb aLingedijk 104, Tricht, the Netherlands; bMinstraat 15bis, Utrecht, the Netherlands (Received 3 March 2017; final version received 10 May 2017) In the nineteenth century Edmond de Selys Longchamps added watercolours, drawings and notes to his extensive collection of dragonfly and damselfly specimens. The majority of illustrations were exe- cuted by Selys and Guillaume Severin. The watercolour collection is currently part of the collection of the Royal Belgian Institute for Natural Sciences in Brussels. This previously unpublished material has now been scanned and is accessible on the website of this institute. This article presents the part of the collection concerning the following sous-familles according to Selys: Calopterygines (currently superfamilies Calopterygoidea and Epiophlebioidea), Cordulines (currently superfamily Libelluloidea), Gomphines (currently superfamily Petaluroidea, Gomphoidea, Cordulegastroidea and Aeshnoidea) and Aeschnines (currently superfamily Aeshnoidea). This part consists of 750 watercolours, 64 drawings and 285 text sheets. Characteristics and subject matter of the sheets with illustrations and text are pre- sented. The majority (92%) of all sheets with illustrations have been associated with current species names (Calopteryines 268, Cordulines 109, Gomphines 268 and Aeschnines 111). We hope the digital images and documentation stress the value of the watercolour collection of Selys and promote it as a source for odonate research. Keywords: Odonata; taxonomy; Severin; Zygoptera; Anisozygoptera; Anisoptera; watercolours; draw- ings; aquarelles Introduction The watercolour collection of Selys Edmond Michel de Selys Longchamps (1813–1900) did important work in odonate classifi- cation and taxonomy (Wasscher & Dumont, 2013; Verspui & Wasscher, 2016).

INTRODUCTION The South-West Province of Cameroon forms of what the part was formerly British Cameroons. There are some lowland areas in the South and West, but the province is predominantly hilly, perhaps about 60% of the terrain being above 600 m in altitude. These uplands (the Western Highlands) are made of Pre-Cambrian rocks overlain by volcanic material. There are also several peaks which rise from their surroundings to altitudes of 2000-3000 m. The southernmost one of these is Mount Kupe (4°48’N, 9°42’E), which reaches 2050 m. In the South, the volcanic Mount Cameroon (4°13’N, 9°11’E) rises to 4095 m and is separated from the rest of the upland regions by heavily-cultivated lowlands. The nearest peak to Mount is distance ofabout 86 km. The records in Cameroon Mount Kupe, a presented this refer the vicinities of Mount and Cameroon with the paper to Kupe only, greater emphasis being placed on the formermountainat which Birdlife Internationalhave recently established a reserve.

  • Critical Species of Odonata in Western Africa

    --- Guardians of the watershed. Global status of dragonflies: critical species, threat and conservation --- Critical species of Odonata in western Africa Klaas-Douwe B. Dijkstra 1 & Graham S. Vick 2 1 Gortestraat 11, 2311 MS Leiden, The Netherlands. <dijkstra®naturalis.nnm.nl> 2 Crossfields, Little London, Tadley, UK. <camdragonfly®aol.com> Key words: Odonata, dragonfly, IUCN, critical species, conservation, western Africa. ABSTRACT Western Africa - defined as the tropical area from Cameroon westwards - probably has the richest odonate fauna in Africa, particularly the region of (and around) the Cameroon highlands. This region is home to many relict and endemic species, such as the continent's only representatives of the families Amphipterygidae and Perilestidae. Previous selections of threatened West African Odonata have been arbitrary because it is impossible to differentiate between species that are genuinely endangered and those which are simply data-deficient. Many listed species just appear to be difficult to record or have been taxonomically confused; some 'en­ dangered species' have already dissolved into synonymy. A revised and probably more complete selection of species requiring attention is provided, but because the source data is so scanty it remains subjective. Species in Gomphidae and Corduliidae are not included, as the knowledge of their taxonomy and distribution is particularly problematic at present. Many listed species may prove to be of minor concern once more research in the field and in the museum has been done. It is argued that if rainforest reserves (existing in most nations discussed) are main­ tained, the great majority of West Africa's unique Odonata will be protected. Although most rare species are probably stenotopic rainforest inhabitants, open landscapes also harbour a rich and potentially endangered odonate fauna.

The primary objective of the study was to determine the species composition and community structure of the odonate fauna occurring in the forests. The goal is to infer the health status of the two forests. Three study sites were selected, one in each of the main water bodies in the forests (Rivers Kienke and Linde in Kribi forest, and River Bitande in Campo Ma’am National Park). All the specimens collected were identified to the lowest taxonomic level. A total of one hundred and ninety four (194) individuals of Odonata were collected in the forests comprising 10 families, 24 species of Anisoptera and 30 species of Zygoptera. Anthropogenic activities were less prevalent at Campo Ma’am National Park, an area in which all the 10 families were incidentally recorded. The community structure of the southern forest revealed that only River Bitande with Shannon-Wiener diversity index (H`) of 3.80 was having a stable environmental condition.
