Pseudagrion lorenzi sp. nov. is described from New Britain island, Papua New Guinea. Male and female characters are illustrated by means of scanning electron microscopy. A differential diagnosis with Pseudagrion civicum Lieftinck, 1932 from New Guinea and Pseudagrion incisurum Lieftinck, 1949 from the Solomon Archipelago is provided. The female of P. incisurum is described for…
The larva of Heliaeschna uninervulata is described and figured for the first time. Its characters mostly fall within the limits of variation of Gynacantha spp. Comparison of the larval characters of H. filostyla, the only other member of the genus for which the larva is known, suggests that it is not congeneric with H. uninervulata….
The female of Mortonagrion ceylonicum is described and figured for the first time. The female was described briefly by Laidlaw (1924) but was not assigned to a genus or species. An amended description of the male is also provided. Additional notes on habitat, distribution and behaviour are given.
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…
Indocypha catopta sp. nov. (holotype ♂: China, Guizhou, Maolan National Nature Reserve 28 vii 2008, to be deposited in the Collection of Aquatic Insects and Soil Animals, Department of Entomology, South China Agricultural University, Guangzhou) is described, illustrated and compared with all known Indocypha species. The uncertain taxonomic status of some Chinese Indocypha species is…
Teinobasis cryptica sp. nov. (holotype ♂: Borneo, Sarawak, Bahagian Samarahan, Kota Samarahan, old UNIMAS campus, disturbed peatswamp forest, 25 ii 2008, RMNH) from Malaysia is described from both sexes and compared with other Teinobasis species known to occur in Malaysia. The members of the genus known from Sundaland are reviewed. Records of T. ruficollis from…
The F stadium larva of both sexes of Tetracanthagyna plagiata is described and figured based on exuviae from which confirmed adult specimens had been reared. Larvae were originally collected in small, slow forest streams in Singapore, and in captivity were fed on local shrimp and small fish species. The known larvae of Tetracanthagyna species, T….
When comparing the phenology of species within the family Lestidae in Numidia, northeastern Algeria, we found that: (1) four of five species—Lestes barbarus, L. numidicus, L. viridis, and Sympecma fusca—feature a prolonged pre-reproductive period approaching five (Lestes spp.) or eight months (S. fusca); (2) adults of L. numidicus, and probably of S. fusca, move to…
With a total of 75 species the odonate diversity in the Namibian desert is surprisingly high. Based on their distribution characteristics, invasion patterns, and breeding success, there are six well-defined categories of Odonata: widespread species – (1) permanently living in the desert, and desert biased, (2) permanently living in the desert, but not desert-biased; (3)…
Microsatellite loci have become the genetic markers of choice for population-level molecular ecological studies. However, microsatellite loci had been isolated for comparatively few species of odonate until the past five years. This review summarises the main characteristics – expected heterozygosity and microsatellite length – of 116 microsatellite loci that have been isolated from the genomes…
