Brachythemis leucosticta was found to include two morphotypes, which we consider to represent separate species. Males are separable by the ventral structure of S8 and often differ in the colour of the venation and genital lobe. Females are as yet not reliably distinguishable. Examination of 1,154 males demonstrated that both species are widespread: the true…
A comparison of the description of Brachythemis liberiensis with material of B. leucosticta and Parazyxomma flavicans has shown that B. liberiensis is a synonym of P. flavicans. B. liberiensis should be removed from the list of threatened African Odonata. The relationships between the genus Brachythemis and the Zyxommatini are briefly discussed. Further arguments for a…
Polymorphism has rarely been reported from dragonflies of the Libellulidae (Odonata: Anisoptera) family. Here, we report female-limited polymorphism in females of five species of the Libellulidae and a gynandromorph male of Brachythemis contaminata from South Asia. We describe the morphological variation between andromorph and heteromorph females, and collate records of andromorph females from various sources….
Of the 86 Odonata species so far recorded for the Levant, four are considered as endangered (Calopteryx hyalina, C. syriaca, Ceriagrion georgifreyi, Pseudagrion torridum hulae), six as vulnerable (Coenagrion vanbrinckae, P. sublacteum mortoni, Gomphus kinzelbacbi, Onychogomphus macrodon, Brachythemis fuscopalliata, Crocotbemis sanguinolenta), and two as extinct (Rhyothemis semihyalina syriaca, Urothemis edwardsi hulae). The history of odonatological…
