Title : A peculiar new species of Nyodes Laporte, 1970 (Lepidoptera: Noctuidae)
Abstract : A new, externally atypical Nyodes is described from Equatorial Africa: Nyodes paludicola sp. nov. The new species is compared to the superficially most similar Nyodes steelei Laporte, 1971, and N. punctatoides Laporte, 1973, with the closest genital morphology. The new species is associated with wetland habitats and is widely distributed in West, Central and East Africa. Genetic divergence between the geographically distant populations has been assessed based on mtDNA COI barcodes.

Title : Degrees of specialism in butterflies: a method for defining levels of specialism and an evaluation of South African species
Abstract : Butterflies may be specialists, generalists, or somewhere in between. In this paper, we propose a method for defining various categories of specialism, test the robustness of the method, and allocate all South African butterfly species to a category. The results are then evaluated and discussed.

Title : The genera of the tribe Charaxini (Papilionoidea, Nymphalidae, Charaxinae)
Abstract : The systematics of Charaxini is revised. The three historical genera are confirmed: Charaxes (Ochsenheimer, 1816); Polyura (Billberg, 1820) and Euxanthe (Hübner, 1819). The genera Eriboea (Hübner, 1819) status rev.; Zingha (Hemming, 1939) status rev.; Viridixes (Bouyer & Vingerhoedt, 2008) status rev. and Euxanthe subgenus Hypomelaena (Aurivillius, 1898) status. rev. are reinstated. Three new genera are described: Laodice genus nov. with the type species Papilio lycurgus (Fabricius, 1793); Setechin genus nov. with the type species Charaxes nichetes (Grose-Smith, 1883) and Ydeali genus nov. with the type species Charaxes lydiae (Holland, 1917). A key to the nine genera is provided.
Résumé: La systématique des Charaxini est revue. Les trois genres historiques sont confirmés : Charaxes (Ochsenheimer, 1816); Polyura (Billberg, 1820) et Euxanthe (Hübner, 1819). Les genres Eriboea (Hübner, 1819) status rev.; Zingha (Hemming, 1939) status rev.; Viridixes (Bouyer & Vingerhoedt, 2008) status rev. et Euxanthe sous-genre Hypomelaena (Aurivillius, 1898) status. rev. sont réhabilités. Trois nouveaux genres sont décrits: Laodice genus nov. avec comme espèce type Papilio lycurgus (Fabricius, 1793); Setechin genus nov. avec comme espèce type Charaxes nichetes (Grose-Smith, 1883) et Ydeali genus nov. avec comme espèce type Charaxes lydiae (Holland, 1917). Une clé dichotomique permet de séparer les neuf genres.

Title : Description of a new species from Africa in genus Coccothera Meyrick, 1914, with additional taxonomic and faunistic information on two other Coccothera species (Lepidoptera: Tortricidae: Grapholitini)
Abstract : A new species from Africa is described in the genus Coccothera Meyrick, 1914 (Lepidoptera: Tortricidae: Grapholitini). Coccothera albolineana spec. nov. Laspeyresia nicomacha Meyrick, 1921 is transferred to Coccothera Meyrick, 1914 comb. nov. The unknown male is described and a full description of the hitherto only partly known female genitalia is presented. Coccothera ferrifracta Diakonoff, 1968 is a synonym of Coccothera spissana (Zeller, 1852) syn. nov. The genus Coccothera Meyrick, 1914 now contains eight species. Faunistic and distributional information of Coccothera spissana (Zeller, 1852), C. nicomacha (Meyrick, 1921) and C. albolineana spec. nov. is also presented.

Title : Taxonomic revision of the tribe Acraeini Boisduval, 1833 (Papilionoidea: Nymphalidae: Heliconiinae)
Abstract : The systematic and taxonomic history of the tribe Acraeini is reviewed. Using a robust dated molecular phylogeny published in 2021, and combining this with morphological and ecological data-sets, we divided the clearly paraphyletic genus Acraea (sensu lato) into five genera. We raised the subgenera Rubraea Henning, 1992, Stephenia Henning, 1992 to genera and reinstate Bematistes Hemming, 1935 and Telchinia Hübner, [1819] as valid genera. The genus Tildia gen. nov. is erected for a monophyletic clade of Acraea (sensu lato), and we treat the Neotropical Actinote and the Afrotropical Telchinia as separate genera. Because of the relatively low sampling of ‘Telchinia’ species in the dated molecular phylogeny we suggest that the possibly paraphyletic Telchinia be further investigated using more complete sampling. We furthermore present an updated alpha taxonomy for the six Afrotropical genera in the tribe – Acraea, Rubraea stat. nov, Stephenia stat. nov, Tildia gen. nov., Bematistes stat. rev. and Telchinia stat. rev. The current alpha taxonomy of the New World genus Actinote and the Old World genus Cethosia is given.
