Arctornis sclerotuncus Holloway sp. n.
Diagnosis
♂ 19mm. The diaphanous wing facies appears similar to that of aureopalpatus, though the specimen is worn. The frons has a deep pinkish set of markings as in sinuoharpe, but with a slight rufous tinge ventral to the white area. The palps are rufous-yellow, the legs unspotted. The male genitalia are distinguished from those of sinuoharpe by the narrow, sclerotised uncus, the sinous harpe with its greatest flexure subbasally and subapically, rather than just the former as in sinuoharpe. The valve is deeper, and the aedeagus has a single apical spine.
