Narrow-lobed Glider

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 dark patch at the base of the hindwing is usually conspicuous. In males, the genital lobe is long and narrow, a feature reflected in the species name stenoloba.

Tramea stenoloba inhabits riverine lagoons, lakes and ponds, including temporary ponds.

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.
