Tramea tillyardi Lieftinck, 1942 | |
Tramea loewii, commonly known as the common glider, is a species of dragonfly in the family Libellulidae.[4][3]
It occurs from Indonesia and New Guinea through Australia and the western Pacific to New Caledonia.[5] The species is recently self-introduced to New Zealand.[6]
Tramea loewii is a medium to large dragonfly with dark patches at the base of the hindwings, a striped thorax, and a red abdomen in males.[5]
Taxonomic history
In 1866, Brauer published the description of Tramea loewii using the manuscript name proposed by Kaup.[2] Brauer noted that Kaup had already assigned names to many specimens sent to him for study, and that he generally retained those names unless they were already occupied.[7]
In 1942, Lieftinck reviewed Indo-Australian populations of Tramea loewii and described the Australian form as Tramea loewii tillyardi.[8] He regarded the Australian populations as closely related to specimens from Ceram and western New Guinea, differing mainly in thoracic colouration and minor differences in the male genitalia.[8]
Tramea tillyardi is now treated as a synonym of Tramea loewii.[3]
Description
Tramea loewii is a medium to large dragonfly with a wingspan of about 85 mm and a body length of about 45 mm.[5]
The thorax is striped yellowish to brown on a purplish background.[5] Males have a red abdomen with black markings near the tip, while females are dull brown.[5] Dark patches at the base of the hindwings are characteristic of the species; these patches are red in males and brown in females.[5]
Tramea loewii is similar in appearance to Tramea stenoloba, but differs in the colouration of the thorax and the structure of the secondary genitalia.[5]
Distribution and habitat
Tramea loewii inhabits a wide range of still-water habitats including ponds, swamps and lagoons.[5]
In Australia it is widespread except for the far south-west of the continent.[5]
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.[7]
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.[7]
In 1866, J. J. Kaup named this species löwii, now loewii, an eponym honouring either the German entomologist Hermann Loew (1807–1879) or the Austrian physician and entomologist Franz Löw (1829–1889).[2][7][9]
