Newly described are two new species of Spiloxene Salisb.:  S. nana Snijman from the Bokkeveld Escarpment, Northern Cape Province, is a shade-loving plant with narrow, pale green leaves and small, white or rarely cream-coloured flowers; S. pusilla Snijman from the Matsikamma, Gifberg and Pakhuis Mountains. Western Cape Province, resembles S. nana in habit but the yellow- or white-tepalled flowers which are tetramerous or hexamerous have darkly coloured stamens and style and an ovary with a short, solid, narrow prolongation at the apex. Inhabiting rock overhangs formed by quartzitic sandstone sheets, both species are close allies of S. scullyi (Baker) Garside from Namaqualand.

The Asiatic blue tick, Rhipicephalus microplus, a known vector of bovine babesiosis and bovine anaplasmosis, is of great concern in the cattle industry. For this reason, detailed knowledge of the distribution of R. microplus is vital. Currently, R. microplus is believed to be associated mainly with the northern and eastern Savanna and Grassland vegetation in South Africa. The objective of the study was to record the distribution of R. microplus, and the related endemic Rhipicephalus decoloratus, in the central-western region of South Africa that comprises Albany Thicket, Fynbos and Savanna vegetation. In this survey, ticks were collected from 415 cattle in four provinces (Eastern Cape, Northern Cape and Western Cape and Free State provinces) and from the vegetation in the Eastern Cape province of South Africa between October 2013 and September 2015. More than 8000 ticks were collected from cattle at 80 localities of which R. microplus was present at 64 localities and R. decoloratus at 47 localities. A total of 7969 tick larvae were recorded from the vegetation at 20 localities of which 6593 were R. microplus and 1131 were R. decoloratus. Rhipicephalus microplus was recorded in each of the regions that were sampled. Rhipicephalus microplus is now present throughout the coastal region of the Eastern Cape province and at multiple localities in the north-eastern region of the Northern Cape province. It was also recorded in the western region of the Western Cape province and one record was made for the Free State province. The observed range changes may be facilitated by the combined effects of environmental adaptability by the tick and the movement of host animals.

Plants until now identified as Drimia marginata (Thunb.) Jessop on account of their leathery, oblong to elliptical leaves with thickened, cartilaginous margins and capitate inflorescences of campanulate flowers, are shown to comprise three sets of populations separable on leaf morphology, ecology and distribution. Typical D. marginata produces 1 (2) oblong, apiculate leaves with retrorsely-scabridulous margins and occurs in fine-grained clay soils on the Hantam and Roggeveld Plateaus. Plants from Namaqualand and the Richtersveld. described here as Drimia pulchromarginata J.C.Manning Goldblatt. occur in sandy or gravelly soils and produce 2 -4 , elliptical to suborbicular, apiculate leaves with an ornate, duplex margin: the dorsal surface bears a submarginal band of dense, velvety trichomes fringing the thickened, colliculate margin. A third series of populations from seasonally moist sandstones at higher altitude on the interior mountains of the West Coast produces2 or 3(4) narrowly oblong, obtuse leaves with a simple, papillate or colliculate margin and are recognized as D. ligulata J.C.Manning Goldblatt. A fourth taxon with a similar capitate inflorescence of campanulate flowers produces a solitary, subterete or subclavate leaf, elliptical in section. Recorded from scattered localities in the Northern and Western Cape', it is here described as D. vermiformis J.C.Manning Goldblatt.

The Republic of South Africa, known as South Africa, occupies the most southern tip of Africa with a coastline stretching from the border of Namibia on the Atlantic Ocean (south-west coast) of Africa, down to the tip of Africa and then north along the south-east coast to the border of Mozambique on the Indian Ocean. South Africa is bordered by Namibia, Botswana, Zimbabwe, Eswatini (formerly Swaziland), and Mozambique and surrounds the small landlocked Kingdom of Lesotho in the east-central region of South Africa. The total area of South Africa is approximately 1.22 million square kilometres (km), with a population of an estimated 58.78 million (2019). The country is divided into nine provinces, Western Cape, Eastern Cape, Northern Cape, Free State, Kwa-Zulu Natal, Northwest, Gauteng, Mpumalanga, and Limpopo. Gauteng Province is the most densely populated province with approximately 809.6 people per square kilometre, Kwa-Zulu Natal being the second most densely populated at 120.7 people per square kilometre, with Western and Eastern Cape following substantially behind at 59.1 and 51.1 people per kilometres respectively. There are three capitals in South Africa: Pretoria in the Gauteng province (administrative), Cape Town in the Western Cape (Legislative), and Bloemfontein in the Free State (Judicial). The

Four new species of Kazimierzus are described from the Western Cape and Northern Cape, South Africa: K. kleinoodi sp. n., K. nietvoorbiji sp. n., K. nieuwoudtvillensis sp. n., and K. phumlani sp. n. Kazimierzus kleinoodi is distinguished from the other species of this genus by the position of the calciferous glands in 9 and paired spermathecae in five segments. The position of the spermathecae in 11/12–15/16 as well as the position of the calciferous glands in 11 separates K. nietvoorbiji from the other new species. Kazimierzus nieuwoudtvillensis is distinguished from the others by the position of the clitellum (12–25) and spermathecae in four rows. The combination of the position of the clitellum, three rows of spermathecae and the position of the calciferous glands in 10 distinguish K. phumlani from the other species.

Detailed Assessment

Acanthopsis is a taxonomically poorly understood genus confined to arid parts of southern Africa. This contribution is the first detailed assessment of the diversity within the Acanthopsis disperma-hoffmannseggiana complex, the latter of which comprises the bulk of the specimens of the genus represented in herbaria. Species concepts are resolved and the misapplication of names is noted. In addition to the recognition of A. disperma and A. hoffmannseggiana, five new species of Acanthopsis formerly treated under these two names, are described, namely A. tuba and A. ludoviciana (both confined to the Richtersveld, Northern Cape, South Africa), A. adamanticola (endemic to southern Namibia), A. villosa (endemic to Bushmanland, Northern Cape) and A. dispermoides (endemic to the Western Cape, South Africa). The names A. disperma and A. hoffmannseggiana are lectotypified here. An identification key to the members of the Acanthopsis disperma-hoffmannseggiana complex is provided, as well as an interim key to the major artificial groupings in the genus, the taxonomy of some which still needs to be resolved.

Established Species

Fifteen years after establishing the genus Beckhoplia Dombrow, 2005 a large amount of new material collected has warranted a critical review of the established species and a revision of the genus. From this process, we describe fifteen new species from the Northern Cape Province and Western Cape Province of the Republic of South Africa: Beckhoplia bicolor Dombrow, new species, B. caliginosa Dombrow, new species, B. castanea Dombrow, new species, B. dolichiocnemis Dombrow, new species, B. elkeae Dombrow, new species, B. fusca Dombrow, new species, B. gifbergensis Dombrow, new species, B. nigra Dombrow, new species, B. nigrofasciata Dombrow, new species, B. nigrosetosa Dombrow, new species, B. pallidibrunnea Dombrow, new species, B. pulchra Dombrow, new species, B. pumilla Dombrow, new species, B. setosa Dombrow, new species and B. suturalis Dombrow, new species. Two cryptic species complexes within the species B. colvillei Dombrow, 2005 and B. occidentalis Dombrow, 2005 were detected. A revised key of the genus and observations about its biogeography are given. Important details of the morphological characters of the body and the parameres of the species are illustrated and their distributions are mapped. We also provide habitat and host plant information.
