The taxonomy of Acanthopsis is poorly understood, resulting in great difficulties in distinguishing and identifying infrageneric taxa. In this contribution a taxonomic account of the shrublet members of Acanthopsis is provided. Four species are recognized, two of which are newly described, namely A. dregeana and A. erosa (both confined to the Northern Cape Province, South Africa). Acanthopsis trispina, hitherto only known from the orginal collection, is considered a synonym of A. horrida. Acanthopsis spathularis has been recollected after more than 180 years and its status as a distinct species is confirmed. The names A. spathularis and A. horrida are lectotypified here. An identification key to the species of the shrublet group in Acanthopsis is provided.

Two new species of the genus Paragus Latreille, 1804 are described from the Republic of South Africa: Paragus longipilus Tot, Vujić et Radenković sp. nov. and Paragus megacercus Tot, Vujić et Radenković sp. nov. These new species belong to the subgenus Pandasyopthalmus Stuckenberg, 1954a. Paragus longipilus sp. nov. is a member of the P. jozanus group, whereas Paragus megacercus sp. nov. belongs to the P. tibialis group. The taxonomic status of Paragus chalybeatus Hull, 1964 is revised and proposed as synonym of Paragus punctatus Hull, 1949. Additionally, an identification key to males of the South African species of Paragus is provided. Results of the present study confirm a significant level of endemism of Paragus in the Afrotropical Region (12 out of 29).

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.

Trachyandra eriocarpa and T. bulbosa are two new species from Northern and Eastern Cape Provinces of South Africa. They are placed in T. sect. Liriothamnus based on their wiry roots, the cataphylls not forming membranous collars, and the remains of the outer leaves forming a fibrous collar. Trachyandra eriocarpa from the Great Winterberg in Eastern Cape is recognised by its unusual, villous ovary and capsules; and T. bulbosa from north of Springbok in Northern Cape by the irregular, bulbous rhizome, microscopically puberulous leaves and maculate tepals.

Two New Species

Two new species from South Africa, Dactylonotus nigricorpus sp. nov. and Dactylonotus tsitsikamma sp. nov., are described and illustrated. D. nigricorpus sp. nov. differs from all other species of the genus in the black body, the smaller size and the shorter antenna. D. tsitsikamma sp. nov. is peculiar in the genus in bearing a flag of long setae on the fifth segment of the fore tarsus. An identification key to 6 Afrotropical species of the genus is provided.

Pelargonium hammansbergense and P. roseopetalum are described as new species. Both are deciduous geophytes with turnip-shaped tubers belonging to P. section Hoarea. These two species share spathulate petals with narrow cuneate claws.  However, they differ in leaf shape, flower colour and markings on the petals. Their flower structure corresponds to that of P. aridicola, P. hirtipetalum, P. pubipetalum, P. reflexipetalum and P. tripalmatum. The seven species are compared with regard to the flower and leaf morphology, palynology and chromosome numbers. They all occur in the winter rainfall region along the west coast of South Africa. The two new species described here are illustrated and a key for the identification of the seven species with a P. aridicola flower type is included.

Capezoum Adlbauer, 2003 is known only from male specimens. Herein, we describe two new species: Capezoum richardi sp. nov. and C. brunneopunctatus sp. nov., from the Northern Cape region in South-Africa. The discovery of these new species, one of them represented by both sexes, allowed us to describe the hitherto unknown female. Moreover, the genus is transferred to the tribe Xystrocerini and a key to the species of the genus is provided. Lastly, the position of Mythozoum Thomson, 1878 in Cerambycidae is discussed.

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.

Two new annual species of Nemesia Vent, are described from southern Africa. Nemesia suaveolens is characterized by magenta and yellow flowers. It differs from the closely related N. euryceras by having a lower lip that is yellow rather than white with pale violet margins, an upper lip with a conspicuous yellow rectangular patch just above the corolla opening, a spur that is ± equal to the length of the lower lip, not half the length, and a hypochile that is yellow rather than dark violet.This new species is known only from the arid Tanqua Karoo east of the Cedarberg Mountains. N. aurantia is characterized by orange saccate flowers with a brown and orange bearded palate. It is closest to N. versicolor, but differs from that species by its orange corolla, the absence of a spur, and its bearded palate with brown and orange trichomes. It is known from a single locality adjacent to the Swart Doting River in Namaqualand between Nuwerus and Garies.

Three New Species

Acanthopsis is a poorly understood genus taxonomically, confined to arid parts of southern Africa. The density of the inflorescences and the morphology of the bracts are taxonomically useful characters for species delimitation. This contribution focuses on the taxonomy and conservation status of those members in the genus characterized by semi-dense inflorescences with 5-fid bracts, all of which are confined to arid parts of the Northern Cape Province, South Africa. Six species, A. carduifolia, A. glabra, A. glandulopalmata, A. insueta, A. nitida and A. scullyi, are recognized in this group. Three new species, A. glandulopalmata, A. insueta and A. nitida, are described. An identification key to the species of the group with semi-dense spikes and 5-fid bracts is provided.
