Palaeugoa Durante, 2012 View in CoL , European Journal of Taxonomy, 22: 5.

Type species: Xanthetis spurrelli Hampson, 1914 , by original designation ( Durante 2012).

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 (this uncus structure is unique within the Asura / Miltochrista generic complex, but similar to certain groups of Cyana Walker, 1854 which have, however, only the tip of uncus separated from the tuba analis). (2) The transtilla either bears a large process in its diaphragmal part (in the P. spurrelli species-group) or on the anterior section of the editum (in the takanoi species-group), or its diaphragmal part is heavily spinulose and fused with the spinulose scobination of the anellus (the P. peregrina species-group). (3) The sacculus bears one or two processes, of which the distal one is well-separated from the distal section of the valva (‘cucullus’). The female genitalia are characterized by (1) the short or reduced apophyses anteriores; (2) the presence of an antevaginal plate (except in the P. peregrina species-group); (3) the tubular and membranous ductus bursae (in other species of the Asura / Miltochrista generic complex, the ductus bursae is dorso-ventrally flattened and sclerotised, with the exceptions of the Oriental Barsochrista N. Singh & Kirti, 2016 and Nebulene Volynkin & Černý, 2018 where the ductus bursae is also membranous but short and broad); (4) the large appendix bursae having a very broad and membranous distal section, which is larger than or about the same size as 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 reaching western Kenya ( Kakamega Forest) in the east ( Volynkin & László 2020).
