Tramea eurybia, commonly known as the dune glider, is a species of dragonfly in the family Libellulidae.[4] It occurs from Southeast Asia through New Guinea to Fiji, and in Australia is found mainly at coastal dune lakes in eastern Australia.[5][6]

It is a medium-sized dragonfly with red, brown and black markings and a distinctive dark patch at the base of the hindwing.[7]

Taxonomic history

In 1878, Selys described Tramea eurybia from specimens collected in Sulawesi.[2]

In 1967, Watson reviewed Indo-Australian species of the Tramea eurybia group, examining the relationships between Tramea eurybia and related species including Tramea stenoloba.[8] Watson recognised Tramea eurybia as a widespread species occurring from the Andaman Islands through the Indonesian archipelago and New Guinea to Australia and Fiji.[8]

Description

Tramea eurybia is a medium-sized dragonfly with red, brown and black markings and a distinctive dark patch at the base of the hindwing.[7]

It is similar in appearance to Tramea stenoloba, but differs in the structure of the reproductive appendages of the male and the vulvar scale, a structure beneath the abdomen of the female.[7][8][9]

The thorax is reddish-brown to red, with limited dark markings.[8] In males, the front of the head is orange-red to deep red, with a narrow metallic band along the rear margin.[8] The dark patch at the base of the hindwing is usually large and lacks the surrounding pale border seen in some related species.[8]

Distribution and habitat

Tramea eurybia occurs from the Andaman Islands through the Indonesian archipelago and New Guinea to Fiji.[8][5]

In Australia it is found mainly at coastal dune lakes in eastern Australia.[6]

Outside Australia the species inhabits a wider range of still-water habitats.[7]

Etymology

The genus name Tramea is derived from the Latin trameare ("to pass through" or "travel across"), referring to the migratory or vagrant behaviour of species in the genus.[10]

The former genus name Trapezostigma is derived from the Greek τραπέζιον (trapezion, "trapezium") and στίγμα (stigma, "spot" or "mark"), likely referring to the shape of the pterostigma.[10]

The species name eurybia is derived from Εὐρυβία (Eurybia), a minor sea goddess in Greek mythology.[10]
