On the taxonomy of the genera Cyana Walker, Palaeugoa Durante, Euproctosia Hampson, and Lymantriopsis Hampson from continental Africa with the description of five new genera, three new subgenera, and fifteen new species (Lepidoptera: Erebidae: Arctiinae: Lithosiini)

The paper is devoted to the taxonomy of certain Afrotropical genera related to Cyana Walker, 1854, viz. Palaeugoa Durante, 2012, Euproctosia Hampson, 1914, and Lymantriopsis Hampson, 1900. Vulpeculella Karisch, 2013, stat. n. is raised to genus level from a subgenus of Cyana. The genus-group names Paravulpeculella Karisch, 2013 and Louisia Karisch, 2013 are transferred from Cyana to Vulpeculella at the rank of subgenera: Vulpeculella subgenus Paravulpeculella Karisch, 2013, stat. rev. and Vulpeculella subgenus Louisia Karisch, 2013, stat. rev. The genus-group name Cyabarda Karisch, 2013 is synonymised with Paravulpeculella. Five new genera, three new subgenera, and fifteen new species are described: Vulpeculella (Vulpeculella) admiranda sp. n. (Democratic Republic of Congo), Reticuligoa gen. n. (type species: Palaeugoa asafis Volynkin & László, 2020), Reticuligoa meyi sp. n. (Uganda), Palaeugoa (Sacculigoa) subgen. n. (type species: Palaeugoa smithi Volynkin & László, 2020), Palaeugoa (Sacculigoa) montana sp. n. (Cameroon), Afroadites gen. n. (type species: Palaeugoa ndoki Volynkin, 2024), Afroadites phebe sp. n. (Cameroon), Euproctosia (Pseudoproctosia) subgen. n. (type species: Euproctosia (Pseudoproctosia) pemba sp. n.), Euproctosia (Pseudoproctosia) pemba sp. n. (Tanzania), Lymantriopsis mysterica sp. n. (Liberia, Ghana), Euproctosiella gen. n. (type species: Euproctosiella elegans sp. n.), Euproctosiella elegans sp. n. (Republic of Congo), Euproctosiella amabere sp. n. (Uganda), Processosia gen. n. (type species: Processosia (Processosia) obscura sp. n.), Processosia (Processosia) obscura sp. n. (Republic of Congo, Democratic Republic of Congo, Gabon, Uganda, Liberia), Processosia (Processosia) banco sp. n. (Ivory Coast), Processosia (Armatosia) subgen. n. (type species: Processosia (Armatosia) imbalanga sp. n.), Processosia (Armatosia) imbalanga sp. n. (Republic of Congo), Processosia (Armatosia) crystallina sp. n. (Gabon), Processosia (Armatosia) asymmetrica sp. n. (Liberia, Ivory Coast, Ghana), Simplicosia gen. n. (type species: Simplicosia smithi sp. n.), Simplicosia smithi sp. n. (Republic of Congo, Democratic Republic of Congo, Gabon), and Simplicosia nigrescens sp. n. (Republic of Congo). Twenty-one new combinations are introduced: Vulpeculella (Vulpeculella) basisticta (Hampson, 1914), comb. n., Vulpeculella (Vulpeculella) loloana (Strand, 1912), comb. n., Vulpeculella (Vulpeculella) ueleana (Karisch, 2003), comb. n., Vulpeculella (Vulpeculella) rubritermina (Bethune-Baker, 1911), comb. n., Vulpeculella (Vulpeculella) rawlinsi (Karisch, 2013), comb. n., Vulpeculella (Vulpeculella) rubriterminalis (Strand, 1912), comb. n., Vulpeculella (Vulpeculella) luchoana (Karisch, 2003), comb. n., Vulpeculella (Paravulpeculella) pallidilinea (Karisch, 2003), comb. n., Vulpeculella (Paravulpeculella) torrida (Holland, 1893), comb. n., Vulpeculella (Paravulpeculella) nambi (Volynkin & László, 2019), comb. n., Vulpeculella (Paravulpeculella) suessmuthi (Karisch, 2013), comb. n., Vulpeculella (Louisia) quentini (Karisch, 2003), comb. n., Vulpeculella (Louisia) yaseminae (Baron & Karisch, 2016), comb. n., Vulpeculella (Louisia) smithi (Volynkin & László, 2019), comb. n., Reticuligoa takanoi (Volynkin & László, 2020), comb. n., Reticuligoa asafis (Volynkin & László, 2020), comb. n., Afroadites aristophanousi (Volynkin & László, 2020), comb. n., Afroadites laszloi (Volynkin, 2024), comb. n., Afroadites ndoki (Volynkin, 2024), comb. n., Afroadites ngoko (Volynkin & László, 2020), comb. n., and Afroadites peregrinus (Hacker, 2014), comb. n. Lectotypes are designated for Euproctosia cretata Hampson, 1914 and Nudaria lacteata Holland, 1893. Adults and male and female genitalia of the taxa considered are illustrated.
