Hesperocordulia berthoudi, known as the orange streamcruiser, is a medium-sized orange, red and black dragonfly with clear wings and very long legs.[7] It inhabits streams, rivers and pools,[8] and its conservation status is assessed as Near Threatened.[1]
Taxonomy
Hesperocordulia was described by Robin Tillyard in 1911 as part of the corduliid group.[2] It has subsequently been assigned to several different families in historical classifications.[9] Phylogenetic studies have since clarified its relationships, and it is now placed in the family Austrocorduliidae.[4][10]
Etymology
The genus name Hesperocordulia combines the Greek ἑσπέρα (hespera, "evening" or "west") with Cordulia, a genus name derived from the Greek κορδύλη (kordylē, "club" or "cudgel"). The name possibly refers to the occurrence of the species in south-western Western Australia.[11]
In 1911, Robin Tillyard named this species berthoudi, an eponym honouring his friend George Berthoud (1856-1936) of State Farm, Hamel, Western Australia, who collected the original specimen.[2][11][12]
