Identification:
This species shares characteristics with the genus Lethe previously described. It is a small species, comparable in size to L. confusa. The dorsal coloration of the male is similar to that of L. europa.
Male ventral side: Dark in color with prominent, circular eyespots: 4 eyespots are located in the mid-area of the forewing, positioned vertically and nearly parallel to the outer wing margin. These 4 spots, along with a light-colored line starting from the upper margin and cutting across towards the inner and outer wing corners, form a V-shape. The hindwing also features 6 distinct, circular eyespots of varying sizes, arranged sequentially from the mid-upper margin to the outer margin.
Wingspan: 45-50 mm.
Biology and Ecology:
This species is typically observed during early mornings and late evenings. The larval food source is Arumdianaria falcuta, a plant species belonging to the Poaceae family (grasses). It is distributed at altitudes below 1,200m, inhabiting forests, shrubs, grasslands, and caves.
Distribution:
Found in Southern China, Laos, and Vietnam. In Vietnam, this species is present in most northern provinces, ranging from Lang Son to Cuc Phuong.
Conservation Status and Measures:
This species has a more restricted distribution and is less frequently encountered compared to other species within the Lethe genus.
