Notoaeschna sagittata is a species of Australian dragonfly of the family Aeshnidae, known as the southern riffle darner. It is endemic to eastern Australia, occurring south of the Hunter River, New South Wales, where it inhabits rapid streams.
Notoaeschna sagittata is a large, dark brown to black dragonfly with yellow markings. It appears similar to Notoaeschna geminata, the northern riffle darner, which occurs north of the Hunter River.
Etymology The genus name Notoaeschna is derived from the Greek νότος (notos, "south" or "the south wind"), combined with -aeschna, a suffix commonly used for dragonflies associated with the Aeshna group. The name refers to a southern representative of that group.
The species name sagittata is derived from the Latin sagitta ("arrow") and the suffix -atus ("provided with" or "marked with"), referring to spearhead-shaped markings on the abdomen.
