This species is characterized by the silky white hairs and white long scaly hairs densely covering the thorax and abdomen.
Etymology. The patronymic name mogyi is proposed in honor of my colleague and friend Prof. Dr Mohamed El-Mogy, Entomology Department, Faculty of Science, Cairo University, Egypt.
