The taxonomy of Chlorocypha species is problematic due to variability and the paucity of morphological characters. Subspecies radix of C. glauca is raised to specific rank. C. sharpae is found to be a synonym of C. luminosa. The synonymy of C. jejuna with C. luminosa is rejected. The former species is similar to the Southern…
Pseudagrion emarginatum is removed from the synonymy of P. melanicterum. The following synonymies are established: P. coeruleiceps of P. emarginatum and P. angelicum of P. camerunense. The latter, formerly known as Enallagma camerunense, should be removed from the list of threatened African Odonata.
From 12 to 25 August 2009, the odonate fauna of Santo Antão, Cape Verde was surveyed by recording adults and collecting larvae and exuviae at 26 localities, mostly situated in the northwest of the island. Based on the results of this survey and literature data on the Cape Verdes it appears that the resident odonate…
In this report we review the conservation status of Odonata of southwestern Africa, viz Angola, Botswana, Namibia, Zambia and Zimbabwe. In total, 287 species have been recorded of which three have been previously listed by IUCN. We consider 60 species mainly because of their endemism in the region. The majority of the species have to…
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…
Argiagrion leoninum, known only from the female holotype alleged to be West African, is shown to be a junior synonym of the Brazilian species Leptagrion macrurum. Moroagrion danielli, known only from the male holotype thought to be from the Philippines, is a junior synonym of the European Pyrrhosoma nymphula. Argiagrion and Moroagrion were both monotypic…
The region is broadly determined by desert, which forms a huge belt between the western Palaearctic and the Afrotropics. Fourteen out of the 125 odonate species recorded so far are endemics. There are two main centres of endemism in the region: the northern Maghreb and the southern Arabian Peninsula. Odonate habitats in the desert are…
From eastern Africa, ranging from Somalia and Ethiopia south to Mozambique and Zimbabwe and west to eastern Democratic Republic of Congo and Botswana, ca 500 species of Odonata are known. Comments on species and sites of conservation concern are given as well as recommendations for future research and conservation activities. Due to the rapid and…
The global population structure and dispersal patterns of Pantala flavescens (Fabricius, 1798) are evaluated using a geographically extensive mitochondrial DNA dataset, a more limited samples of nuclear markers, wing isotopic (δ²H) data and a literature review. No spatial or temporal haplotype structure was recovered between the samples.
Global warming has altered the ranges of many species, especially those of insects and other ectotherms that are particularly susceptible to rising temperatures. Four decades ago, the dragonfly Crocothemis erythraea began to demonstrate northern range expansion in Germany, as well as in Belgium, the Netherlands, Poland and the UK. The rapid range expansion of C….
