Following on from a recent revision by Kurshakov & Zolotuhin (2013), the genus Strigivenifera Hering, 1937 is reviewed based on recently-collected material held at the African Natural History Research Trust. Investigation of genital morphology and newly-generated barcodes suggested that the diagnoses provided for the species in the previous revision were not entirely reliable for all taxa and as a result, a surplus of names exist in respect to valid species. The following taxonomic changes are implemented: S. livingstonei Kurshakov & Zolotuhin, 2013 syn. n. and S. cruisa Kurshakov & Zolotuhin, 2013 syn. n. are synonymised with S. albidiscalis (Hampson, 1910), S. ocellaris Kurshakov & Zolotuhin, 2013 syn. n. is synonymised with S. eborea Kurshakov & Zolotuhin, 2013 and S. tatooifera Kurshakov & Zolotuhin, 2013 syn. n. is synonymised with S. bartschi Kurshakov & Zolotuhin, 2013. A new species previously confused with S. ocellaris is described from the Western Area Peninsula in Sierra Leone: S. smithi sp. n. The intraspecific variability of the species together with appropriate diagnostic characters for identification are discussed and illustrated and an updated list of the valid species of the genus is provided.

This paper is the first comprehensive summary of the Limacodidae fauna of the Maputo Special Reserve in southern Mozambique, listing 18 species, eight of which are new records for the country. The lectotype of Somara albicosta Hampson, 1910 is designated. Latoia albicosta (Hampson, 1910) syn. nov. is synonymised with Latoia intermissa (Walker, 1865), and Trogocrada dimorpha Janse, 1964 syn. nov. is synonymised with Trogocrada deleter Tams, 1953. The paper is illustrated with 43 colour and 9 black and white diagnostic figures.

As part of a population management strategy for a troop of Guinea baboons (Papio papio) at Yorkshire Wildlife Park, adult females were given a Suprelorin contraceptive implant. There was no information on the effect of contraception on behavior in this species, so behavioral data were collected before and after implant placement to determine any impact on the troops' welfare. Social interactions, affiliative, agonistic, and self-directed displacement behaviors (SDBs) in all adults were monitored via focal sampling. Preimplant data were collected in August/September 2019 before Suprelorin placement on November 2019, and postimplant data were collected in August/ September 2020, allowing for comparison while controlling for seasonal differences in behavior. We found a significant reduction of SDBs after intervention, suggesting that contraception has a positive impact on group welfare, as SDBs are key behavioral indicators of stress and anxiety in nonhuman primates. Additionally, the rate of substate change per hour (i.e., the number of times the baboon changed their behavior), duration of sentry behavior, and the frequency of agonistic bouts were significantly lower postimplant, further suggesting improvements in welfare. There were also no significant decreases in the duration of positive social interactions, such as allogrooming and play.The results show that Suprelorin did not have a detrimental impact on the behavior of adults in the troop and may have even improved welfare. The use of Suprelorin in females could be considered as an effective population management strategy for primates existing in similar social systems.

The taxonomy of the monotypic genus Achrocerides Hering, 1937 is revised using a combination of morphological and genetic evidence. Achrocerides theorini (Aurvillius, 1891) was determined to be a widespread, forest-dwelling species which shows high levels of intraspecific variability in both the external and genital morphology. Examination of the holotype of Chrysopoloma flavoantennata Berio, 1937 revealed this to be a rare species of Achrocerides exhibiting a large body size, and a new combination is introduced thus: Achrocerides flavoantennata (Berio, 1937) comb. n. Finally, a new species is identified from the Central African Republic and is herein described: Achrocerides smithi sp. n. The adults and genitalia of all taxa are illustrated, and a distribution map provided to facilitate identification.
