Diagnosis. Macrobathra is characterized by the labial palpus with the third segment longer than the second segment, and the antenna with the scape elongated; the lanceolate forewing with R 4 stalked with R 5, the wider hindwing with Rs and M 1 parallel basally, farther apart distally; in the male genitalia by the symmetrical or rarely asymmetrical socius and the valva with dense setae distally; in the female genitalia by the accessory bursae arising from the ductus bursae, and the corpus bursae with paired signa.

Macrobathra is similar to Pancalia Stephens, 1829 in the labial palpus with the third segment longer than the second segment, the fore- and hindwings having a same vein pattern, and the aedeagus not integrating with the anellus. Macrobathra differs from Pancalia in the forewing with a distinct fascia and without tubercular spots of shining metal luster.

Macrobathra is geographically distributed in the Australian, the Ethiopian, the Palaearctic and the Oriental regions.

Host plants of the genus Macrobathra include Acacia spp. of Fabaceae [Leguminosae] ( Meyrick 1922), Quercus serrata Thunberg and Q. glauca Thunberg of Fagaceae ( Moriuti 1973) , Cunninghamia lanceolata (Lamb.) of Taxodiaceae ( Qian & Liu 1997) .
