The Brenton Blue butterfly became nationally famous in the 1990s when the Lepidopterists' Society of Africa (LSA) launched a campaign to prevent its imminent extinction, because of the development of a luxury housing estate at Brenton-on-Sea on the southern coast of South Africa. This campaign gained support from national and international NGOs as well as the South African public and pressure mounted on the National Government to intervene. Eventually the Brenton Blue Butterfly Reserve (BBBR) was established to protect the butterfly in 1997, with the status of a “special nature reserve”. An intensive research project was conducted from 2000–2005, which uncovered the butterfly's unusual ecological requirements, including the caterpillar's habit of feeding on the rootstock of its host plant Indigofera erecta under the protection of Camponotus baynei ants. The vegetation composition and dynamics, the biology of the host plant, the ant community and the population dynamics of the butterfly were also outcomes of this research. This facilitated the development of a reserve management programme, which for over 20 years seemed to ensure the butterfly's survival. Fire exclusion was practiced because of the risk to the host ants, which nest in dead wood on the surface. Despite these precautions, during the unprecedented Knysna fire in June 2017 the entire butterfly reserve was burnt, and even though some butterflies emerged in November 2017, these were the last ones seen at the BBBR.

Robinson & Kirke (1990) reported the occurrence of Melipotis obliquivia (Hampson, 1926) on Ascension Island. After more material was available for genitalia dissection and barcoding, the identity of the Melipotis population on Ascension has been verified. The specimens are conspecific with Melipotis famelica (Guenée, 1852), which is widely distributed in southern North America, the Caribbean, Central and South America. On Ascension the species is quite common, with a focus on the Green Mountain.

Three new species from Africa are described in the genus Coccothera Meyrick, 1914 (Lepidoptera: Tortricidae: Grapholitini). Coccothera yangambiana sp. nov., Coccothera willydeprinsi sp. nov. and Coccothera juratedeprinsi sp. nov. Diagnostic characters are illustrated and described, and the type locality is illustrated. The biology and distribution of the species are not known except for the collecting dates and locality.

Male and female genitalia show that two species are confused under the name Liptena undina (Grose-Smith & Kirby, 1894); the new species, which flies in the eastern part of the range of L. undina, is named L. dunnia sp. nov. It has two subspecies, the nominate in the east and subspecies reducta ssp. nov. in the west. New data are also provided on the distribution of Liptena ochrea Hawker-Smith, 1933.

Les genitalia mâles et femelles montrent que deux espèces sont confondues sous le nom de Liptena undina (Grose-Smith & Kirby, 1894). La nouvelle espèce, qui vole dans la partie orientale de l'aire de répartition, est nommée L. dunnia sp. nov.; elle comporte deux sous-espèces, la sous-espèce nominative à l’est et la sous-espèce reducta ssp. nov. à l’ouest. Des nouvelles données sont fournies sur la distribution de Liptena ochrea Hawker-Smith, 1933.

New faunistic data from Namibia are given for the family Metarbelidae. A total of 17 species are recorded and a new species is described: Metarbela dietermeyi sp. nov. The adults of the new species and specimens of Lukeniana raymondrevellii and two Selagena species are illustrated in colour. The male genitalia and wing venation of M. dietermeyi sp. nov. are depicted as line drawings and its systematic position is briefly discussed.
