basal portion, grey costal edge and wide grey submarginal area with serrated inner edge and big round discal spot. Hind wing milky-white with small grey basal portion,

wide grey submarginal area with serrated inner edge and big round discal spot.

DISTRIBUTION. Indonesia, Province Papua.

ETYMOLOGY. The new species is named after Professor Walter Karl Johann

Roepke (1882–1961), a prominent Dutch entomologist, who indicated this interesting new species and did a great research in Lepidoptera of South-Eastern Asia including

Cossoidea. Roepke was the Director of The Central Java Experiment Station and then Entomologist at the Institute of Plant Diseases and Pests of Buitenzorg; later served as the Professor at the Agricultural College, Wageningen, where he arrived in 1919 to teach Tropical agriculture till 1925, and from 1925 till his retirement in

1953 – Applied entomology (Kalshoven & Diakonoff, 1961).

with labels (1–3) and female genitalia (4). 1 – holotype; 2–4 – paratypes.

Thus, currently the family includes 4 genera (two of which, Sumatratarda and

Praesaturnia , are monotypic), uniting the nine described species. The new finding significantly enlarges the area of the family Ratardidae in the east to New Guinea

Island. It was previously considered that the family representatives inhabit East

India, Indochina ( Myanmar, Thailand), Taiwan, the Philippines (Palawan Island),

Malaysia and Indonesia to the east to the Moluccas (Halmahera Island) (Yakovlev,

2018 a, b). The general distribution of the species of this little studied family is presented in Fig. 5 .
