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…
Prodasineura doisuthepensis sp. nov. from Thailand is described and figured. The holotype and two paratypes were collected by the author on 11 May 2002 on the slopes of Doi Suthep, Chiang Mai Province, Thailand (18°48′N, 98°56′E). The material will be deposited at the Naturhistorisches Museum Basel (NHMB). The female is unknown. This is the only…
The reproductive behaviour of Neurobasis kaupi was studied for the first time in Central and South Sulawesi. The species was recorded in a wide variety of clear and fast flowing creeks, streams and rivers, mostly in forested areas. The males were territorial and defended potential oviposition sites, a limited resource. Territory owners demonstrated their presence…
Thirty-five dragonfly species are reported from Mongolia and Inner Mongolia. Three are first records. A non-parametric test is used to determine the total number of species to be expected. It suggests that the current number of 62 may be asymptotically complete, except for some specific zones like the Bulgan valley in the south-west, and the…
