A New Species

Agistemus collyerae Gonzáles-Rodrigues (Stigmaeidae) is reported for the first time in South Africa on grapevines in the Western Cape Province. We investigate a possible introduction pathway of this mite as a contaminant on imported agricultural goods. Based on South African interception data, we report new country records of A. collyerae in the USA, Chile, Yemen, Spain and France. We re-describe it based on the South African specimens, including first-time descriptions of the male and deutonymph. Female specimens have shorter dorsal setae than those documented in the original descriptions, but we do not consider this enough evidence to justify a new species.

Annotated Checklist

The Swartberg Nature Reserve is situated in the Large Swartberg mountain range, in the Oudtshoorn district of the Western Cape Province. Spiders were collected from the reserve over a 10-year period. This is one of the inventory projects of the South African National Survey (SANSA) for spiders of the Succulent Karoo Biome. A total of 45 families comprising 136 genera and 186 species were collected, all which are new records for the area. This represents about 9.4 of the total known South African spider fauna. Of the spiders collected 142 species (76.5 ) were wanderers and 44 (23.5 ) web dwellers. The plant dwellers comprised 43.3 of the total number of species and the ground dwellers 56.7 . The Gnaphosidae was the most diverse family represented by 33 species, followed by the Salticidae with 23 and Thomisidae with 15. Ten species are possibly new to science and the Filistatidae is a first record for South Africa. An annotated checklist with information on the guilds, habitat preference and web types are provided.

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.

A New Species

The first record of the straptail fish, genus Macruronus, from South Africa was based on a single specimen captured off the Atlantic Cape coast and described as a new species, M. capensis Davies 1950. Davies did not examine specimens of the other extant nominal species in the genus, but based his conclusions solely on references to the original descriptions of M. novaezelandiae (Hector 1870) and M. magellanicus Lönnberg 1907. We show that all of the characters used by Davies (1950) to distinguish M. capensis from its congeners are in fact shared by the other nominal species of this genus. We also present molecular evidence from a Macruronus specimen recently caught off South Africa to support the conclusion that M. capensis is a junior synonym of M. novaezelandiae.

In the course of a taxonomic revision of the genus Massonia Houtt., Massonia citrina M.Pinter, Deutsch, U.Müll.- Doblies & D.Müll.-Doblies, a new species of this genus from the Western Cape Province (South Africa), is here described. This species is similar to members of the M. depressa group, but it can be easily distinguished by its yellow filaments and style and the longer perigone-filament tube. A complete morphological description of the new species is presented.

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.

A New Species

A new species of the family Stenothoidae,Wallametopa cylindricasp. nov., is described from samples collected in 2015 in the Knysna Estuary, Western Cape, South Africa. This is the first record of the genusWallametopain South Africa, a genus now being represented by two species found in Africa, Madagascar and Australia.Wallametopa cylindricais closely related to the Australian and MadagascanW. cabonBarnard, 1974, from which it differs by having a distinct cylindrical elongation of the merus of gnathopod 1 in both sexes but more striking in males. Both the basis and the merus of gnathopod 2 are also acutely produced postero-distally. The palmar margin of the propodus of gnathopod 2 in males is strongly, irregularly incised and with a deep, broad excavation (larger male). The dactylus reaches the whole length of the propodus and is densely setose on the inner margin.

A New Species

A new species of soft scale (Hemiptera: Coccomorpha; Cocccidae) from South Africa, Coccus giliomeei Łagowska & Hodgson sp. n., collected on Gymnosporia buxifolia (L.) Szyszyl, is described and illustrated. Also, Coccus rhodesiensis (Hall) is recorded for the first time from South Africa and is redescribed and illustrated based on the adult females of the type series and fresh South African specimens. An updated key to the species of Coccus and similar species known from Africa is included. Based on this latter study, (i) Marsipococcus proteae (Brain) and M. durbanensis (Brain) are considered not to be congeneric with Marsipococcus marsupialis (Green), the type species of Marsipococcus Cockerell & Bueker, and are placed in a new genus Proteacoccus Łagowska & Hodgson, gen. n. with Lecanium proteae Brain as the type species; (ii) it is considered that Coccus asiaticus Lindinger is clearly not a junior synonym of Parasaissetia nigra (Nietner) and is accepted as a full species, rev. stat., and (iii) Neoplatylecanium adersi (Newstead) is considered to be non-conspecific with N. cinnamomi Takahashi, the type species of Neoplatylecanium Takahashi, and is transferred to Maacoccus Tao & Wong, as Maacoccus adersi (Newstead), comb. n.
