The primary and secondary types as well as some non-type material donated by Jason Londt (and various collaborators) to the Natural History Museum, London (NHMUK) have been examined and databased which comprises 35 holotypes, 293 paratypes, and 18 non-types (added for completeness), a total of 328 type specimens from 103 species (6% of the total Afro-tropical fauna). All specimen labels were imaged, both frontal and reverse sides, alongside the specimen. Notes were made of any dissections or damage to the specimens. Additional notes were made of any differences between the labels from the species descriptions and the actual specimens.

Amphoterus Bezzi, 1915 is a genus of rarely collected Afrotropical hover flies (Diptera, Syrphidae). We present the first description of the female of A. braunsi van Doesburg, 1956, redescribe the males of A. braunsi van Doesburg, 1956 and A. cribratus Bezzi, 1915, and describe a new species, A. londtisp. nov. We also provide the first colour photographs of two of the species, the first DNA barcodes for the genus and a key to identify the species.

Jason G.H. Londt contributed almost a quarter of the KwaZulu-Natal Museum’s specimens of Cicadidae, including a strong sample of females, and probably the best set to date of African records of predation on cicadas by robber flies. The collection provides evidence that robber flies catch more male cicadas; speculatively, because attacks on the heavier-bodied female fail more often. The metadata derived from these specimens also provide a small gazetteer of Londt’s collecting sites.
Jason G.H. Londt贡献了夸祖鲁-纳塔尔省博物馆近四分之一的蝉科标本，其中包括大量的雌性蝉标本，而且可能是迄今为止非洲关于盗蝇捕食蝉的最佳记录。收集的证据表明，盗蝇捕获的雄性蝉更多;据推测，这是因为对体型较重的雌性的攻击更容易失败。来自这些标本的元数据还提供了Londt采集地点的小型地名表。

A new species of Bittacus Latreille, 1805 is described based on two specimens from Gorongosa National Park in Mozambique. Bittacus londti sp. nov. is the second known Afrotropical Bittacus with a femoral bulla and brings the number of species known from Mozambique to four.

A new genus of mygalomorph spider Ekapagen. nov., is described from South Africa. The new genus was formed to include the species Hermacha curvipes Purcell, 1902 and Hermacha nigra Tucker, 1917. These species are synonymized based on their somatic similarities, such as fovea shape, cheliceral teeth distribution, ocular pattern, presence of preening combs, and their close geographic distribution. The new genus proposed is distinguished by the presence of a projection in the retroventral side of the palpal tibia in males, together with a distinctive copulatory bulb shape; and in females by the shape of their spermathecae, with a high base and apical stalks that open into oval apical receptacles.

A colony of the rare hydrozoan siphonophore Lilyopsis Chun, 1885, was observed for the first time in shallow water in False Bay, South Africa, swimming amongst kelp. A study of a high-quality image of this individual found it to share some characters with the prayine prayid L. fluoracantha Haddock, Dunn & Pugh, 2005, so far known only from Monterey Bay, California, in the eastern Pacific. No Lilyopsis species has previously been reliably identified from either the South Atlantic or the Indian Ocean, so this record represents an expansion of the known worldwide distribution for this genus.

The spider genus Ikuma Lawrence, 1938, endemic to Namibia, is rediagnosed and redescribed based on the characters both species originally included in the genus and of the newly described I. larsenisp. nov. A new synonymy is proposed: I. squamata Lawrence, 1938, described from a sole female is recognized a junior synonym of the type species I. spiculosa (Lawrence, 1927), based on a single juvenile. The currently described I. larsenisp. nov. differs from the generotype in the eye arrangement, structure of the abdominal scuta, and details of the colouration. The copulatory organs of both males and females belonging to Ikuma are studied, described and depicted for the first time. The previously known genus range confined to the far north of Namibia extends to the mid-western part of this country.

Male gonopods are useful in taxonomic diagnoses and descriptions of millipedes, although they may vary intraspecifically in shape and size. To assess this intraspecific variation, we used geometric morphometric analysis to compare gonopod morphology among eight isolated populations of the colour-polymorphic southern African millipede Bicoxidens flavicollis. Our results showed that gonopod shapes vary significantly across the examined populations, and elucidated subtle variations. CVA cross-validation test indicates an average classification rate of 75% for the five populations for which we had more than one specimen. Although we had a small number of replicates for three populations, our results still illustrate the importance of applying quantitative approaches to what would otherwise be qualitative and subjective gonopod shape categories in millipedes. As such, the taxonomic assignment of the populations of B. flavicollis may require further investigation, and further revisions would be required with an integrative approach, including molecular data, in order to re-evaluate the taxonomic diversity and distribution data of this species. Finally, we highlight the conservation potential of divergent populations as evolutionary insurance against a dynamic and unpredictable climate, whether or not they undergo full speciation.

Two new Phronia Winnertz, 1864 species—P. hannarostiaesp. nov. and P. ristoisp. nov.—are described from Taita Hills in Kenya, representing the first named species of this genus in the African continent. The new species are morphologically similar to each other as well as to P. flobertae Matile – a species described from the Comoro Islands. These three species can be distinguished by details of the male terminalia, in particular by comparing the structures of the gonostyli. The new species are photographed and hand-drawn figures provided, and their taxonomy is discussed.
