Description of female ( Fig. 3 ). Length of fore wing 40 mm. Antenna simple, not pectinate. Wing pattern resembles that of male. Fore wing slightly wider than in male. Wing mottled: wide dark-brown portion discally from costal edge to medial trunk, light-brown portion with bright dark-brown stroke between CuA 2 and A 1+2 from medial trunk to rear edge of wing, wide dark-brown portion postdiscally, light-creamy portion with dense reticulated brown pattern submarginally and apically. Hind wing grey without pattern. Fringe on all wings mottled: brown at veins, creamy between veins.

Female genitalia ( Fig. 6 ). Ovipositor long, with transverse notches on lateral surfaces; papillae anales cylindrical; apophyses posteriores twice longer than apophyses anteriores; VII sternum strongly sclerotized, consisting of two semicircular parts; ostium poorly submerged; antrum funnel-shaped, strongly sclerotized; ductus bursae copulatrix wide, relatively short, membranous; bursa copulatrix bag-like, elongated, without signa.

Distribution. Southern Myanmar (Tanintharyi Province), Northern Thailand (Nan and Chiang Mai Provinces), Laos (Sainyabuli Province), Malaysia (Malayan Peninsula, Borneo), Indonesia (Kalimantan, Java, Sumatra). New record for Laos.

Composition. Monotypic genus.

Taxonomic position. Morphologically, the genus Groenendaelia Yakovlev, 2004 is most close to the neotropical genus Miacora Dyar, 1905 (Type species: Cossus tropicalis Schaus, 1904 ) ( Figs 5 , 8 ). Their similarity was already discussed by us ( Yakovlev 2014: 58). In the present study, we unite the two genera into one tribe.
