It is shown that Liptena homeyeri straminea Stempffer et al., 1974 is a synonym of Liptena homeyeri Dewitz, 1884, and subspecies Liptena homeyeri bimacula ssp. nov. is described.

The molecular data of Talavera et al. (2020) is re-analysed to provide a foundation for a taxonomic revision of Chrysoritis. A COI phylogeny recovers most of the Chrysoritis species as monophyletic, and a few as polyphyletic but supported by the CAD gene. In the thysbe clade, most species, despite occurring in sympatry with at least one other species in the clade, maintain distinctive wing facies and ecological identity without intermediate forms. Within the thysbe clade, which contains the majority of species, sister taxon comparisons based on the COI phylogeny suggest speciation has been predominantly allopatric and accompanied mostly by minor morphological change and sometimes also a change in male patrolling terrain and/or host ant species. The diversification of the thysbe clade and the taxonomic implications of our results are discussed.

Interest in citizen science, notably biodiversity mapping, has soared recently in Africa, owing to several converging factors. First, is the growing recognition that biodiversity is threatened, and second, there is a need for collective effort among the public to improve the state of biodiversity, driven by human activities. Amongst the important biodiversity components is Lepidoptera (butterflies and moths) which underpin crucial roles in the ecosystem. Although Lepidoptera has been a major field of study for the past decades, its ecology and distribution have only recently gained important attention among the public, particularly in West Africa. This paper reports on the number of butterflies and moths recorded for Nigeria on the LepiMap database. The database contains 1578 records from January 2010 up to August 2021, from 98 quarter-degree grid cells of the 1306 grid cells in Nigeria (7.5% of grid cells). There are 1219 recorded identified to species level (77%), with 359 awaiting identifications, mostly moths. The number of Lepidopterans recorded was 219 species belonging to 16 families. The most frequently recorded species were Catopsilia florella (28 grid cells, 64 records), Telchinia serena (27 grid cells, 61 records), and Danaus chrysippus alcippus (23 grid cells, 49 records). One of the most important successes of LepiMap during the last three years in Nigeria was the increase in the number of observers and coverage by 600%, which is crucial to gathering lepidopteran mapping data for conservation action. It is recommended that data collection be geared toward areas having no or low coverage, yet refreshing old records are also important for understanding changes in species composition across grid cells.

The identity of Asopia onychinalis Guenée, 1854 and its synonyms were studied based on type material and additional specimens from various locations. Lepyrodes astomalis Felder & Rogenhofer, 1875 is considered as a valid species and Nausinoe gueyraudi Guillermet, 2004 from Réunion is considered a junior subjective synonym of astomalis. The genus Chabulina Shaffer & Munroe, 2007 is discussed and is considered to consist of the following species: C. albinalis (Hampson, 1912) (Bocchoris) comb. nov.; C. amphipeda (Meyrick, 1939) (Margaronia) comb. nov.; with its synonym Glyphodes cadeti Guillermet, 1996 syn. nov.; C. astomalis (Felder & Rogenhofer, 1875) (Lepyrodes) comb. nov., with its synonym Nausinoe gueyraudi Guillermet, 2004 syn. nov.; C. bleusei (Oberthür, 1887) (Synclera) comb. nov.; C. cineralis (de Joannis, 1932) (Margaronia) comb. nov.; C. labarinthalis (Hampson, 1912) (Bocchoris) comb. nov., with Bocchoris labyrinthialis Klima, 1939 as a misspelling; C. nuclealis (de Joannis, 1927) (Bocchoris) comb. nov.; C. onychinalis (Guenée, 1854) (Asopia) comb. nov., with its synonym Zebronia braurealis Walker, 1859; C. putrisalis (Viette, 1958) (Diastictis) comb. nov., and C. tenera (Butler, 1883) (Hydrocampa) comb. nov.

A lectotype of Liptena fatima (Kirby, 1890) is designated and the subspecies nigeriana ssp. nov. from Nigeria is described. It is shown that L. fatima does not occur in Ghana, and the distribution of its subspecies is defined. It is also shown that the closely related Liptena alluaudi Mabille, 1890 is present in western Cameroon.
