Austroaeschna sigma is a species of large dragonfly in the family Aeshnidae,[3] known as the sigma darner.[4] It inhabits the upper reaches of small mountain streams in New South Wales and south-eastern Queensland, Australia.[5]
Austroaeschna sigma is a very dark dragonfly with pale markings. It appears similar to the multi-spotted darner, Austroaeschna multipunctata,[4] which inhabits mountain streams in southern New South Wales and Victoria.[5]
Etymology
[edit]The genus name Austroaeschna combines the prefix austro- (from Latin auster, meaning “south wind”, hence “southern”) with Aeshna, a genus of dragonflies.[6]
The species name sigma refers to the Greek letter sigma, corresponding to the English letter "S", and to the shape of a mark on the thorax.[2][7]
