U. suralis was one of a number of specimens described by the lepidopterist William Schaus in a series of articles published across multiple volumes of the Annals and Magazine of Natural History.
Morphology The type specimen was female and measured 32mm in length.
Forewing Schaus describes the forewing as cinnamon-colored with a pinkish hue and the terminal wing and wing base. The forewing is patterned with several white spots edged with "mikado-brown" (a color similar to chestnut). The edge of the forewing is bordered by a fine "snuff-brown" (grayish brown to yellow-brown) line. The edge of the wing is lined with whitish cilia (a fine, hair-like fringe).
Hindwing The hindwing of U. suralis is somewhat punctiform with a slight retraction at the second vein. The hindwing is white and semi-translucent with a cinnamon-buff distal edge (termen); this is bordered inwardly by a dentate brownish line and outwardly by a darker "mikado-brown" (chestnut) line. Head and body U. suralis has a clay-colored head, collar (the area between the head and thorax) and tegulae. The dorsal palpi are cinnamon-colored while the ventral palpi are buff-white. Schaus describes the color of abdomen as "vinaceous-buff" (i.e. wine red-buff).
