Description
In males, the hindwing is 27 to 30 mm in length and the total body length ranges from 34 to 37 mm. The thorax is black with two yellow lines on the dorsum and prominent narrow yellow bands on the sides. Mature individuals develop pruinescence on the thorax, thus obscuring the markings. When viewed dorsally, the shape on the abdomen is characteristic; it broadens quite markedly from the fifth segment and narrows again towards the apex, giving it a spear-shape. Abdominal segments six to eight are bright red above. The eyes are brown on top and pale yellow below. The female has similar thoracic markings with a dark brown (red when young) abdomen.
Superficially, Nesoxenia lineata resembles Agrionoptera insignis, but is easy to separate by the colour pattern of thorax and the distinctive shape of the abdomen.
