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;…
In this article the genus Argiolestes s.str. is defined and three new species belonging to this group are described: A. foja sp. nov. (holotype: Foja Mountains, Indonesia, dep. in MBB}); A. muller sp. nov. (holotype: Baia River, Papua New Guinea, dep. in SAMA); A. roon sp. nov. (holotype: Roon Island, Indonesia, dep. in BPBM). New…
Climate change brings with it unprecedented rates of increase in environmental temperature, which will have major consequences for the earth’s flora and fauna. The Odonata represent a taxon that has many strong links to this abiotic factor due to its tropical evolutionary history and adaptations to temperate climates. Temperature is known to affect odonate physiology…
