Arctornis tricorniger Holloway sp. n.
Redoa sp. 7; Holloway: 1976: 44.
♂♂ 17, 19mm. The facies is much as in the naphtha group with broad irregularities in the satiny reflection from the wings. The frons and palps are extensively rufous-yellow, the latter darker apically. The foretibia has a basal patch of the same colour, and the forewing costa is also slightly tinged yellow.
