The articles published since the author’s Publications on Afrotropical Lepidoptera during 2015, which deal with scientific research into Afrotropical Lepidoptera are listed alphabetically by author(s). Articles dealing with control of Lepidoptera as pests are excluded.

The climber Adenia repanda (Passifloraceae) is a new host-plant species record for Acraea trimeni, Acraea stenobea and Acraea neobule. Final instar larvae and pupae of A. trimeni and A. stenobea are described for the first time. Keys are provided with alignment of terminology to studies of Heliconiinae from the Neotropical Region. The final instar larvae of A. trimeni differ from others in the zetes-group. Use of host-plant A. repanda on the plains of semi-arid Eastern Kalahari Bushveld Bioregion with periodic droughts, is significant for A. trimeni which belongs to a tropical centred zetes-group. A. repanda is favoured by stock and often grows from under the canopies of Boscia albitrunca and Senegalia mellifera subsp. detinens trees. It is hypothesised that low stocking rates and the presence of large predators such as lions (Panthera leo) could favour abundance of A. repanda. A. repanda is an ant-associated plant species whose stems and leaves (with extrafloral nectaries) are constantly patrolled by ants of genera Anoplolepis and Crematogaster. Anoplolepis custodiens attack the larvae of A.neobule on A. repanda rather than forming symbiotic relationships which it has with many myrmecophilous lycaenid larvae.

Life history observations of this herbivorous and myrmecophilous butterfly are described and illustrated here, together with notes on its mutualistic ant symbionts Crematogaster melanogaster Emery and host-plant Hermannia (Malvaceae) species. It was noted that the female oviposited on dead plant material or on the sandy substrate some distance from its host plant. A tentative explanation given for this is that the eggs might otherwise suffer predation by ants nesting beneath the host-plant. A structural and colour similarity exists between the larvae of Argyraspodes Tite & Dickson and larvae of Trimenia Tite & Dickson, Aloeides Hübner and Erikssonia Trimen. This corresponds well with the monophyletic clade of Argyraspodes, Aloeides, Erikssonia and Trimenia as presented by Boyle et al. (2014).

The male of Iolaus (Epamera) malaikae from Mt. Namuli, Zambezia Province, Mozambique is described. The presence of an Iolaus (Epamera) pollux subgroup as a cohesive taxonomic subgroup is questioned; instead it is suggested the two species I. (E.) helenae & I. (E.) malaikae form the basis of a subgroup.
