The genus Malgacheliodes is recorded in South Africa for the first time. Malgacheliodes martensi spec. nov. is described from soil of Hogsback State Forest, Eastern Cape Province. Adults of the new species differ from those of Malgacheliodes guillaumeti by the presence of ribs and furrows in the aggenital region, bacilliform leg tracheae, rounded ventral keel on leg I femur and four pairs of notogastral setae (h1 absent); while its tritonymph differs from that of M. guillaumeti by the presence of five pairs of gastronotic setae (c1 absent). The generic diagnosis of Malgacheliodes is updated. The differences in morphology of the tritonymphal instar in Malgacheliodes and other genera of Licnodamaeidae are presented.

Fluorescence Polarisation

Krimpsiekte (the syndrome associated with chronic cardiac glycoside poisoning) was purportedly induced by Ornithogalum toxicarium in the Karas mountains area of Keetmanshoop, Namibia. This chinkerinchee species was previously linked to a condition known as 'kwylbek' krimpsiekte in small stock in the Beaufort West district of the Western Cape Province, South Africa. In a dosing trial, respiratory distress, tachycardia and sternal recumbency were observed in 2 sheep drenched with fresh plant material. A fluorescence polarisation immunoassay (FPIA) detected the presence of a substance that cross-reacted with digoxin antibodies in some of the plant material collected at Keetmanshoop and Beaufort West. This is the first time that apparent cardiac glycoside poisoning was induced by a southern African chinkerinchee species. The presence of the cardiac glycoside-like substance in O. toxicarium requires further chemical verification.

New records are presented based on a collection of Campylopus specimens made by the second author in the Western Cape Province of South Africa. . The austral species Campylopus clavatus (R. Brown) Wils. in Hook. and Campylopus vesticaulis Mitt. are reported for the first time for Africa, and Campylopus acuminatus Mitt. var. kirkii (Mitt.) J.-P. Frahm is recorded for the second time for Africa. Campylopus arctocarpus (Hornsch.) Mitt. ssp. madegassus (Besch.) J.-P. Frahm is reported for the first time for the Republic of South Africa, and this is the southernmost record of this species. Campylopus simii Schelpe is not synonymous with C. julaceus Jaeg. ssp. arbogastii (Ren. & Card.) J.-P. Frahm but combined here as new as a variety of C. pilifer Brid.

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.

The Status

Historically there has been confusion over the status and identification of Callitriche species in South Africa. Review of herbarium specimens and fieldwork have enabled confirmation of the presence of C. deflexa as a naturalised species in this country and confirmed that C. compressa and specimens named as C. bolusii are conspecific. Field surveys showed that C. compressa still occurs in the areas from which most historic collections were made with no evidence of a decline, it is widespread but local in Kwa-Zulu Natal and Eastern Cape Provinces and extends into eastern Western Cape Province. However because it is known from only five widely scattered sites, it is classed as Vulnerable under the IUCN Red List. We also typify here the names C. compressa and C. deflexa.

A new genus of the spider family Trachelidae L. Koch, 1872 from the Afrotropical Region is described. Capobula gen. nov. is represented by five species, known from South Africa and Lesotho only. Adults of both sexes of Orthobula infima Simon, 1896a, which is widely distributed in the Western Cape, South Africa, are described for the first time, and this species is transferred to Capobula gen. nov. as its type species. Four new species are described: C. capensis spec. nov. and C. neethlingi spec. nov. (South Africa: Western Cape), C. montana spec. nov. (Lesotho and South Africa: Eastern Cape, Free State and KwaZulu-Natal) and C. ukhahlamba spec. nov. (South Africa: KwaZulu-Natal). A phylogenetic analysis based on the cytochrome oxidase subunit I (COI) gene, including 14 genera of Trachelidae, one genus of Clubionidae Wagner, 1887 and three genera of Phrurolithidae Banks, 1892, supports the placement of Capobula gen. nov. in Trachelidae, with Orthobula Simon, 1897 as its likely closest relative.

AbstractThe known Southern African species of the pubescens species-group in the genus Meligethes Stephens, 1830, are revised. A diagnosis of the M. pubescens species-group is given and eight new species are described from South Africa, Namibia and Botswana: M. argentarius sp. n. (Eastern Cape Province, Kwa-Zulu Natal), M. aurivestis sp. n. (Western Cape Province), M. eremita sp. n. (Namibia, Northern Cape), M. hermanniae sp. n. (Western Cape Province), M. massivus sp. n. (Northern Transvaal), M. namakwaensis sp. n. (Namaqualand, Western Cape Province, and southern Namibia), M. pecten sp. n. (Western Cape Province, Free State), and M. rufofuscus sp. n. (Namibia, Botswana, and northern South Africa). Redescriptions and line drawings of male and female genitalia, legs and habitus of M. pubescens Reitter, 1872, M. translatus Grouvelle, 1913, M. confertus Reitter, 1872, M. plumbeus Reitter, 1872, M. fuerschi Spornraft & Audisio, 1995 (= M. antlia Kirejtshuk, 1996, syn. n.), M. marshalli Grouvelle, 1915, and ecological data on most of the species dealt with (all probably using Sterculiaceae of the genus Hermannia as larval host-plants) are also included.
