About Teulisna tumida (Walker, 1862)
This species has a wingspan of 28 mm. A costal lobe is present on the forewing in both sexes. In males, the head, thorax, and basal segments of the abdomen are pale brown, while the terminal abdominal segment is black. The male forewing is pale brown with a purplish tinge and is suffused with fuscous. A black streak runs along the costal base of the forewing, and a large black spot sits at the end of the cell. Male hindwings are yellowish, with fuscous suffusion toward the outer margin. In females, the abdomen is fuscous, and the anal tufts are ochreous. The black spot at the end of the forewing cell is reduced to a minute speck in females. This species is commonly found in lower montane zones, and its larvae feed on mosses.
