S. hilare Schmidt-Gobel from China, Myanmar and India. S. xanthophanum (Bates) from China and Vietnam, including two subspecies: S. xanthophanum xanthophanum (Bates) and S. xanthophanum nigrans (Bates). Some important features and genitalia are illustrated for the first time. Distributional records, diagnoses and a key to species and subspecies are given. S. xanthophanum xanthophanum is recorded from Vietnam for the first time.展开更多
