Remarks on the taxonomy of Megapodagrionidae with emphasis on the larval gills (Odonata)
A list of genera presently included in Megapodagrionidae and Pseudolestidae is provided, together with information on species for which the larva has been described. Based on the shape of the gills, the genera for which the larva is known can be arranged into four groups: (1) species with inflated sack-like gills with a terminal filament;…
The larva of Podolestes orientalis from West Malaysia, with notes on its habitat and biology (Odonata: Megapodagrionidae)
The larva of the south-east Asian megapodagrionid, Podolestes orientalis, is described and figured.

Relict occurrence of East Palaearctic dragonflies in northern European Russia, with first records of Coenagrion glaciale in Europe (Odonata: Coenagrionidae)
The East Palaearctic Coenagrion glaciale and C. hylas are characterized by a current disjunct distribution. New data from northern European Russia significantly modify the earlier known pattern of their distribution. The first European records of C. glaciale and a new record of C. hylas west of the Urals are reported from the environs of Pinega…
Population structure of Polythore procera at a Colombian stream (Odonata: Polythoridae)
We studied a population of Polythore procera along a stream in the Colombian eastern Andean foothills. Mark and recapture samples were made during January to April 2006, covering both dry and wet seasons. We determined population size, daily survival probability, and longevity during the entire period and compared them with precipitation data. Age and sex…
Odonata biodiversity of the Argentine Chaco biome
Odonates of small temporary pools, marshes, large permanent ponds, oxbow lakes, dams, and perennial rivers were sampled in the semiarid Chaco biome of NW Argentina between September 2007 and December 2008. Information from 35 localities yielded 60 species; presence/absence information of species was recorded in a spatial-relational database. Alpha, beta, and gamma diversity and total…

Odonata of Tuva, Russia
The odonate fauna of Tuva in Siberia, Russia, is documented, based mainly on data from expeditions in 1990, 2000 and 2004, and examination of collections preserved in Novosibirsk. The checklist of Tuvinian Odonata presently includes 47 species. In the southern Ubsu-Nur depression 29 species were recorded (two just there); in the Central Tuvinian depression 34…
Crenigomphus kavangoensis sp. nov. from the Okavango River, Namibia (Odonata: Gomphidae)
A new species of Crenigomphus is described and illustrated from a type series of eight males and eight females, all collected along the Okavango River in Namibia during December 2004, three non-type adult specimens and several exuviae (holotype ♂ Namibia, N’Kwazi Lodge, 19 xii 2004, deposited at NMNW). Both sexes lack foliations at S8-9 as…
Lestinogomphus silkeae sp. nov. from the Okavango and Zambezi Rivers (Odonata: Gomphidae)
Lestinogomphus silkeae sp. nov. from the northern Okavango Delta in Botswana, the Kavango River in northern Namibia and the middle Zambezi River in Zimbabwe is described and illustrated (holotype ♂: Botswana, Xaro Lodge, 09 vi 2000, dep. at ZMBH). The shape of the male appendages distinguishes this species from all others in the genus. The…

Leucorrhinia pectoralis can coexist with fish (Odonata: Libellulidae)
The Palaearctic libellulid Leucorrhinia pectoralis is generally considered to be a species inhabiting fish-free water bodies. Yet, a long-term monitoring study of 38 water bodies in NE Germany resulted in 16 species offish being recorded in reproductive habitats of L. pectoralis, with Rutilus rutilus and Carassius carassius as the most numerous and widespread fish species.
Kinematic analysis of maiden flight of Odonata
The maiden flight of five species of Odonata of different families was filmed by slow motion up to 500 f/s and analysed frame by frame. The aim of this study was to find out if the maiden flight differs among various species as well as between tenerals and adults within the same species with respect…
Coloration indicates body size in Calopteryx maculata (Odonata: Calopterygidae)
Calopteryx maculata has become a model system for studying behaviour and reproduction in odonates. Its iridescent coloration is thought to be important in intraspecific interactions but no study has yet measured coloration in a quantitative manner. In a recent study, Fitzstephens & Getty (2000. Animal Behaviour 60: 851-855) showed that lipld levels predict coloration as…
