Tramea stenoloba
species of insect
Tramea stenoloba, commonly known as the narrow-lobed glider, is a species of dragonfly in the family Libellulidae.
It occurs in the Cocos Islands, Lesser Sunda Islands, the Java Sea region and Australia. In Australia it is widespread except for the far south-east of the continent.
Tramea stenoloba is a medium to large dragonfly with a predominantly red thorax, dark patches at the base of the hindwings, and a red abdomen with black terminal segments. Females are duller brown.
Taxonomic history
In 1962, Watson established Trapezostigma stenoloba as a new species from material collected in Western Australia.
In 1967, Watson reviewed Indo-Australian species of the Trapezostigma eurybia group, providing a detailed analysis of Trapezostigma stenoloba and its relationships with related species including Trapezostigma eurybia and Trapezostigma loewii.
The genus Trapezostigma is now treated as a synonym of Tramea.
Description
Tramea stenoloba is similar in appearance to Tramea loewii, but differs in the colouration of the thorax and the structure of the male secondary genitalia.
The thorax is almost uniformly red, with only limited dark markings along the sutures.
The public source identifies “Tramea stenoloba” as species of insect. This brief keeps that definition visible, then builds a research path around Tramea, stenoloba and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Tramea stenoloba”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q2598509. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1962 and 1967.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
