    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.

We list dragonfly observations of a Biodiversity Express Survey to the highland areas in north-west Mozambique, exploring for the first time the Njesi Pla- teau (Serra Jecci/Lichinga plateau), Mt Chitagal and Mt Sanga, north of the provincial capital of Lichinga. A total of 13 species were collected. Allocnemis cf. abbotti and Gynacantha im­ maculifrons are new records for Mozambique. Further key words. 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). While certain mountain ranges within this region have been relatively well studied biologically e.g.

  • The Damselfly and Dragonfly Watercolour Collection of Edmond
    International Journal of Odonatology, 2017 Vol. 20, No. 2, 79–112, https://doi.org/10.1080/13887890.2017.1330226 The damselfly and dragonfly watercolour collection of Edmond de Selys Longchamps: II Calopterygines, Cordulines, Gomphines and Aeschnines Karin Verspuia∗ and Marcel Th. 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).

  • The Atoconeura Problem Revisited: Taxonomy, Phylogeny and Biogeography of a Dragonfly Genus in the Highlands of Africa (Odonata, Libellulidae)
    Klaas-Douwe B. DIJKSTRA National Museum of Natural History Naturalis, Leiden, The Netherlands THE ATOCONEURA PROBLEM REVISITED: TAXONOMY, PHYLOGENY AND BIOGEOGRAPHY OF A DRAGONFLY GENUS IN THE HIGHLANDS OF AFRICA (ODONATA, LIBELLULIDAE) Dijkstra, K.-D. B., 2006. The Atoconeura problem revisited: taxonomy, phylogeny and bio- geography of a dragonfly genus in the highlands of Africa (Odonata, Libellulidae). – Tijdschrift voor Entomologie 149: 121-144, figs. 1-48, tables 1-2. [issn 0040-7496]. Published 1 De- cember 2006. The genus Atoconeura previously comprised two species; one with five subspecies. Principal Component Analysis of 33 characters of 148 specimens and cladistic analysis of 28 charac- ters revealed six discrete taxa, partly with narrowly overlapping ranges. Subspecies aethiopica, kenya and pseudeudoxia of biordinata are raised to specific rank; the synonymy of chirinda with biordinata is confirmed; A. luxata sp. n. is described from West Africa. A key to the species is provided and the poorly known behaviour, ecology and biogeography are discussed. The author has not witnessed oviposition; one report suggests that it may be perched, solitary and epiphytic, which is unusual within the family. The species are largely restricted to streams above 1000 m, except A. luxata sp. n. that is only known below that altitude, but always at the foot of highlands. Four species demonstrate a distribution pattern recalling a ‘ring species’ in high- lands, circling Lake Victoria and the dry north of Tanzania. The phylogeny suggests an expan- sion of the genus from the western lowlands to the eastern highlands, or vice versa, followed by an expansion through the Albertine Rift and Eastern Arc Mts to the Kenyan and ultimately Ethiopian highlands.
