Austrothemis is a genus of dragonflies in the family Libellulidae,[4] endemic to southern Australia.[5][6] The single known species, Austrothemis nigrescens,[7] is commonly known as the swamp flat-tail.[5] It is endemic to southern Australia, where it inhabits lakes and swamps.[8][6] It is a small dragonfly; the male has a flattened abdomen with black and red markings, and the female has black and yellow markings.[5]
Etymology
[edit]The genus name Austrothemis combines the prefix austro- (from Latin auster, meaning “south wind”, hence “southern”) with -themis, from the Greek Θέμις (Themis), the goddess of divine law, order and justice. In early odonate taxonomy, names ending in -themis were introduced by Hagen and were widely used for dragonflies in the family Libellulidae.[9]
The species name nigrescens is derived from the Latin nigresco ("to become black"), referring to the dark colouring of much of the thorax and the markings on the abdomen.[9]
