Syllepte melanopalis is a species of moth in the family Crambidae, subfamily Spilomelinae. The species was first described by entomologist George Hampson in 1912.

Description
The original description by Hampson noted that S. melanopalis possesses the typical wing shape of the genus, with a wingspan ranging approximately 20–30 mm. The forewings are generally brownish‑gray with distinctive darker markings that give the species its epithet “melanopalis” (from Greek melano = black, -palis = band or stripe). Hindwings are similar in coloration but lack the pronounced dark band present on the forewings. Detailed morphological characters, such as genitalia structure, are used to differentiate it from closely related Syllepte species; however, comprehensive illustrations are limited in publicly accessible literature.
Distribution
Records indicate that Syllepte melanopalis occurs in the Indo‑Australian region, with confirmed presence in:
- Papua New Guinea – notably in lowland rainforest habitats.
- Northern Australia – occasional specimens have been collected from Queensland coastal forests.
The full extent of its range remains poorly documented, and additional populations may exist in adjacent tropical areas.
Habitat and Ecology
Syllepte melanopalis inhabits tropical and subtropical forest environments, where its larvae are presumed to feed on understory herbaceous plants or low‑lying shrubs, a feeding habit common among many Spilomelinae. Adult moths are nocturnal and are attracted to light, which facilitates their collection in light‑trap surveys. Specific host‑plant relationships have not been conclusively identified, and life‑cycle details (egg, larval instars, pupation) are not well recorded in the literature.
Conservation Status
The species has not been evaluated by the International Union for Conservation of Nature (IUCN). Its relatively limited known distribution and the paucity of ecological data preclude an accurate assessment of conservation concerns.
