This regional taxonomic revision of the genus  Wellstedia  Balf.f., a member of the family Boraginaceae  s.I. (including Hydrophyllaceae s.str.), is part of a series of publications on the Boraginaceae in southern Africa.  Wellstedia comprises six species, five in Socotra, Somalia and Ethiopia with the remaining one.  W. dinteri Pilg.. occurring in southern Africa.  W dinteri Pilg. subsp. dinteri occurs in Namibia and the Northern Cape, whereas the newly instated subspecies W. dinteri subsp. gracilior (D.R.Hunt) Retief A.E.van Wyk, based on W. dinteri Pilg. var. gracilior D.R.Hunt, is confined to Namibia only. The disjunct distribution of Wellstedia and numerous other plant and animal taxa between the arid regions of northeastern Africa and southern Africa is usually explained by the postulated periodic existence of an arid corridor between the two regions during the arid phases of the Pleistocene and even earlier.  Wellstedia is treated here in Wellstedioideae, a subfamily of Boraginaceae s.I. but is sometimes placed in a family of its own, Wellstediaceae Pilger. Morphologically Wellstedia displays strong similarity to genera of the Ehretioideae and also to certain members of the Hydrophyllaceae. The genus is characterized by a perennial, dwarf shrub habit, densely hairy leaves. 4-merous flowers, a terminal, bifid style and a 1- or 2-seeded capsule. A key to the two subspecies, diagnostic characters, a distribution map and illustrations of various macro- and micromorphological features are provided.

Ants of the Tetramorium solidum group occur in Africa, with the vast majority of species endemic to the arid regions of southern Africa. The first revision of the genus was published more than 30 years ago and ant surveys have since considerably expanded the number of specimens available for study. The revision of this group reveals five new species, expanding the total number to 19. Almost all the species in this group occur in the southern parts of the Afrotropical region, with the exception of T. setuliferum Emery, 1895 and T. rothschildi (Forel, 1907). These two species have broad distributions within African grasslands and savannas, with T. setuliferum occurring in southern Africa and T. rothschildi in East Africa and the Sahel. Five new species are described in this revision: T. aisha sp. nov., T. brigitteae sp. nov., T. duncani sp. nov., T. lerouxi sp. nov. and T. margueriteae sp. nov. An illustrated key is presented and descriptions of new species are provided, supported by montage images and distribution maps.

Family Level

Spiders of the family Philodromidae are free-living active predators, with laterigrade legs, eyes without tubercles, two tarsal claws and claw tufts. Although very common in zoological collections, their systematics is poorly known, especially in the Neotropics, and their specimens are usually identified only at family level. In this paper, the genus Gephyrellula Strand, 1932 is revised and the type species, G. violacea (Mello-Leitão, 1918) is redescribed and illustrated. Gephyrellula paulistana (Soares, 1943) is considered a junior synonym of G. violacea and thus, the genus becomes monotypic. In addition, the geographical distribution is extended and an updated distribution map is provided.

The genus Buglossoides Moench, a member of the family Boraginaceae. subfamily Boraginoideae. tribe Lithospermeae. is revised tor the Flora of southern Africa (FSA) region.  Buglossoides comprises about seven species of annual, biennial or perennial herbs and subshrubs native to Asia, southern Europe and northern Africa.  B. arvensis (L.) I.M Johnst.. a naturalized weed in many parts of the world, is the only member of the genus represented in the flora of southern Africa, presumably introduced with imported cereal seed. Although the similar polyaperturate pollen grains of  Buglossoides and Lithospermum support the view that they are congeneric, they are retained as separate entities here. Diagnostic characters, a full description, various illustrations and a distribution map of B. arvensis in southern Africa are given.

Local Representative

This is the first of several projected articles dealing with the southern African Aneuraceae H.Klinggr. The family is cosmopolitan and comprises two subfamilies, only one of which, the Aneuroideae. with two genera. Aneura Dumort. and Riccardia Gray, occurs locally. Because of the taxonomic problems associated with this family and the scarcity of  fruiting material, only one taxon in the genus Aneura, A. pinguis (L.) Dumort., has so far been accepted in this treatment. This is not meant to imply, however, that A. pseudopinguis Herzog does not occur in southern Africa: only, that the specimens I have examined, all belong to A. pinguis. A description and illustrations of A. pinguis. together with a distribution map are provided.

Home movies, like family photographs, are important parts of family life, acting as ways to frame the idea of the family and connect different, inter-generational memories together. Footage of key moments helps develop a family identity, as well as locate it within broader historical contexts. As a result, home movies provide an incredibly useful source with which to examine the intersections between narratives of the family, nation and belonging. Utilising a collection of personal home movies, this paper will explore how these themes are touched on within the context of British Colonial Southern Africa. These films explore how ideas of family identity are rooted within ideas of home and belonging, articulating a conceptualisation of colonial Southern Africa as a ‘home-scape’ for descendant of British settlers living there during the 1950s and 1960s. These home movies draw attention to the creation of the idea of home and family, while also producing disruptive elements to those narratives.
