Sixteen species of Latrunculiidae Topsent, 1922, belonging to the genera Latrunculia du Bocage, 1869, Strongylodesma Lévi, 1969, Cyclacanthia Samaai & Kelly, 2004, Samaai & Kelly, 2002, are currently known from the temperate waters of South Africa. Extensive new sponge collections from the Amathole region of South Africa revealed the existence of three new species of Tsitsikamma, T. amatholensis sp. nov., T. madiba sp. nov., and T. beukesi sp. nov., and a new species of the endemic South African genus Cyclacanthia, C. rethahofmeyri sp. nov. With the recent addition of two new species of Tsitsikamma from Algoa Bay and Tsitsikamma National Park (T. michaeli Parker-Nance, 2019; T. nguni Parker-Nance, 2019) the total number of known South African Latrunculiidae is now 20 species in four genera. Here we propose two new subgenera of Tsitsikamma, Tsitsikamma Samaai & Kelly, 2002 and Clavicaulis subgen. nov., based on the morphological groups “favus” and “pedunculata” hypothesized by Parker-Nance et al. (2019). Species in the nominotypical subgenus Tsitsikamma, containing the type species, are thick encrusting to hemispherical with a rigid honeycombed choanosome, while species in the new subgenus Clavicaulis subgen. nov. have a purse or sac-like morphology with little choanosomal structure. Despite the obvious species-level differences in morphology, multivariate analysis based on spicule measurements (anisostyle length, discorhabd length, shaft and whorl length) was not able to distinguish between the proposed Tsitsikamma species, but separated known species T. favus Samaai & Kelly, 2002, T. pedunculata Samaai & Kelly, 2003, and T. scurra Samaai & Kelly, 2003, from each other. Similarly, DNA barcoding of the mitochondrial COI  and the nuclear ITS of Tsitsikamma specimens failed to clearly differentiate between species, but was able to differentiate sister taxon relationships within the Latrunculiidae.

A new species of the endemic South African genus Stenomastigus Leleup (Staphylinidae, Scydmaeninae, Mastigini), S.pseudofranzi sp. n. is described. Because some morphological structures of the new species highly resemble those of S.franzi Leleup, description of the latter species is supplemented with previously unknown details of the aedeagus (includingthe copulatory piece). Habitus, aedeagi, modified fore legs of males and other diagnostic characters of both species are illustrated.

Capalictus, a new subgenus of Lasioglossum Curtis, 1833 (Hymenoptera, Apoidea, Halic-tidae), endemic to the South African Cape Province, is described. The type species is Halictus mosselinus Cockerell, 1945. Evylaeus (Sellalictus) fynbosensis (Pauly et al., 2008) is a new junior synonym of L. (C.) mosselinum. Three new species are described: Lasioglossum (Capalictus) hantamense sp. nov., L. (C.) tigrinum sp. nov. and L. (C.) timmermanni sp. nov. DNA sequence data from three nuclear genes support morphologically-determined species limits. Capalictus is a basal clade of the Hemihalictus series of Lasioglossum.

AbstractThe New World genus Erythrothrips is redefined and a key to the species provided. A new genus and species, Erythridothrips cubilis, is described from Australian tropical rain-forest. The South African genus Audiothrips is withdrawn from synonymy with Erythrothrips and a new species, A. senckenbergiana, is described. The sole African species in the American genus Stomatothrips is transferred to the African genus Allelothrips. The relationships of these taxa are discussed, together with reasons for questioning the validity of the tribe Orothripini.

Macrobiotus furciger Murray, has been considered a probable cosmopolitan species. The authors examined specimens named M. furciger from two subantarctic areas from New Zealand, and from South Africa and noted that in the subantarctic area two species are present: M. furciger and a new species here described and named Macrobiotus aradasi sp. nov. The specimens from New Zealand belong to a different species here described and named Macrobiotus divergens sp. nov., and the specimens from South Africa belong to a third new species here described and named Macrobiotus sicheli sp. nov. The authors also hypothesize that the records of Macrobiotus furciger from Andamane Islands and from Europe may refer to different species.

Trechodes intermedia sp. nov. and T. kogelbergensis sp. nov. are described from South Africa. A third species, T. humeralis (Jeannel, 1930) comb.nov. is transferred to Trechosia Jeannel from the genus Cothresia Jeannel. All three species are macropterous, endemic to the South African Cape region, and together represent a new species group of the genus Trechosia. Keys to the species groups of the genus Trechosia and to the species of the new T. intermedia group are provided.

A new South African species of the genus Chaperiopsis is described from material deposited in the Muséum National d'Histoire Naturelle, Paris. Chaperiopsis stephensoni is redescribed and figured from the original material.The genus Chaperiopsis Uttley, 1949 is widely distributed in the southern hemisphere. Numerous species of this genus have been described in different works; notable amongst these are the works of Busk (1854, 1884), Kluge (1914), Uttley (1949), Gordon (1984), Hayward & Thorpe (1988), Reverter Gil & Fernández Pulpeiro (1995) and Hayward (1995). Some previous records of Chaperiopsis spp. from South Africa are included in the works of Jullien (1881), Busk (1884), O'Donoghue & De Watteville (1935), O'Donoghue (1957) and Hayward & Cook (1983).

The genus Stuckenbergomyia Smith is revised with the description of a new species from Namibia (S.namibiensissp. nov.) and an undescribed species based on females from Western Cape Province of South Africa. The genus is fully illustrated and its phylogenetic relationships within the Hybotidae are discussed with the proposal of a new subfamily, Stuckenbergomyiinaesubfam. nov.

The branchial-attaching cymothoid genus, Elthusa Schioedte & Meinert, 1884 is a genus with a worldwide distribution of 36 species, including the three species described here. Elthusaraynaudii (Milne Edwards, 1840) is the only species that has been described from southern Africa. All South African material held at the National Museum of Natural History, Paris, France (MNHN) and the Iziko South African Museum, Cape Town (SAMC) identified as, or appearing to belong to, Elthusa was examined. Four species were identified, Elthusaraynaudii and three species that proved to be undescribed. Elthusaxenasp. n. can be distinguished by an evenly rounded pereonite 1 anterior margin, a roughly rectangular pleotelson, and narrowly rounded uropod apices that extend to more than half the length of the pleotelson. Elthusaacutinasasp. n. is identified by the produced and narrowly rounded cephalon anterior margin, acute uropods that are shorter than half the length of the pleotelson, and pereonite 1 anterior margin with medial projection. Elthusarotundasp. n. is characterised by the round body shape, broadly rounded uropod apices, and protrusions on the proximal and lateral margins of the merus and carpus of pereopod 7. A key to the South African Elthusa species is provided, together with a table summarising the hosts and localities of the 33 previously known species of Elthusa.

Background: Berkheya is a large, mainly southern African genus of approximately 75 species, several of which are poorly known and under-collected. Since revision in 1959, only a few new species have been described. Publication of new taxa facilitates conservation objectives and contributes to a better understanding of the southern African flora.Objectives: The objectives of this study were to describe a new species of Berkheya, consider its taxonomic position within the genus and assess its conservation status.Methods: Macromorphology and micromorphology of the new species were compared with known species.Results: Berkheya dumicola N.G.Bergh Helme was described from two subpopulations from the northern Bokkeveld escarpment, Northern Cape Province, South Africa. The species is a tall shrub with radiate flowerheads, toothed receptacle alveole margins, a uniseriate pappus of small, rounded scales and very short twin-hairs on the cypsela.Conclusion: Berkheya dumicola is a new species with a unique combination of features. Based on morphological characteristics, its closest relative within the genus is likely to be the recently describedBerkheya chrysanthemoides J.C.Manning Goldblatt. The limited geographic extent and small population size of B. dumicola warrant an International Union for Conservation of Nature (IUCN) status of ‘Endangered’.
