Palaeugoa Durante, 2012 , European Journal of Taxonomy, 22: 5 (Type species: Xanthetis spurrelli Hampson, 1914 , by original designation).

Diagnosis. The male genitalia of the species of the genus are characterized by the combination of the following characters: (1) the uncus is short, dorso-ventrally flattened and fully fused with the tuba analis (such an uncus structure is unique within the Asura / Miltochrista generic complex, but similar to certain groups of Cyana having, however, only the tip of uncus separated from the tuba analis); (2) the transtilla either bears a large process ( P. spurrelli and takanoi species groups) or is strongly thickened, spinulose and fused with the dorsal part of the anellus ( P. peregrina species-group); (3) the sacculus bears one or two processes, of which the distal one is well-separated from the cucullus. The female genitalia are characterized by (1) the broad and well-sclerotized 8 th abdominal segment; (2) the short or reduced apophyses anteriores; (3) the presence of antevaginal plate; (4) the tubular and membranous ductus bursae (in other species of the Asura / Miltochrista generic complex the ductus bursae is dorso-ventrally flattened and sclerotized, with the exceptions of Barsochrista N. Singh & Kirti, 2016 and the subgenus Nebulene Volynkin & Černy, 2018 of the genus Ovipennis Hampson, 1900 where the ductus bursae is also membranous but short and broad); (5) the very broad and membranous appendix bursae, which is larger than or about the same size of the corpus bursae (this character is also unique within the Asura / Miltochrista generic complex and similar to that of the genus Cyana ).

Distribution. The genus is widespread in the rainforests of West and Central Africa.
