Three New Species

Over the last five decades, only two new species of Syllis (Syllidae, Annelida) have been described from South Africa, suggesting a greatly underestimated richness and the expectation that many more indigenous species still remain undescribed. In this paper, we describe three new species from algal turf along a rocky shore on the south coast of South Africa. All three species are characterised by having pseudo-simple chaetae by loss of blade and enlargement of shafts together with compound heterogomph bidentate falcigers. Syllis zahri sp. nov. (up to 5 mm long) is characterised by light pink to light brown colouration on its prostomium and anterior chaetigers, dark transverse bars that fade towards the posterior region, superior anterior chaetae having short spines and posterior parapodia with distally hollow aciculae. Syllis jaylani sp. nov. (up to 7 mm long) is narrow anteriorly, relatively wider at midbody and tapers posteriorly toward the pygidium, has a pharyngeal tooth slightly back from the anterior margin, strongly bidentate chaetae with teeth perpendicular to the main shaft, thin sinuose bidentate ventral simple chaetae with a serrated edge and pseudo-simple chaetae with a serrated edge in anterior parapodia. Syllis bunaa sp. nov. (up to 9 mm long) shows a characteristic dark brown colouration on its prostomium and anterior region, is distinctly rounded dorsally, and has unidentate or minutely bidentate chaetae, up to three pseudo-simple chaetae on parapodia along the whole body and posterior ventral simple chaetae that are thick with rounded tips or sinuose with a serrated inner edge.

Three New Species

The examination of a collection of fleas, obtained during the last two years in the course of the investigation of plague amongst the rodents of the South African veld, has resulted in the finding of three new species of Xenopsylla, which are described below.My thanks are again due to Dr. K. Jordan and to Dr. G. A. K. Marshall for advice and help kindly given to me.

Almost All

Another three new species of Riccia in section  Pilifer Volk are described from Namaqualand, namely  R. furfuracea, R vitrea and R. namaquensis. There are certainly more undescribed species present in that region, but species from there are often very difficult to distinguish: almost all have hyaline scales, the free-standing dorsal cell pillars need to be examined in living plants and the spore ornamentation is quite variable.

Three New Species

Field studies of the sub-Saharan African and largely southern African Hesperantha conducted since 2003 have resulted in the discovery of three new species in this genus, bringing the total to 82. Hesperantha longistyla J.C.Manning Goldblatt. known from one collection from the mountains of SW Namibia, is a dwarf plant with moderately long-tubed, purple flowers and unusually long style branches, possibly allied to the Kamiesberg species,  H. latifolia. A second species,  H. helmei Goldblatt J.C.Manning, also known from a single collection from the interior mountains of Eastern Cape near Graaff- Reinet, has terete leaves and small flowers with tepals ± 8 x 2.5 mm, about as long as the perianth tube. It is apparently most closely allied to the Roggeveld species, H. cliolata. A third novelty, H. lithicola J.C.Manning Goldblatt. restricted to the Swartruggens range in the eastern Cold Bokkeveld, has bell-shaped corms with toothed margins, leaves 1-2 mm wide, and white flowers with a tube 10-12 mm long, and appears most closely allied to the widespread H. falcata. A new collection of H karooica from northeast of the Hantamsberg represents a small but significant range extension for this local endemic previously known from just two collections near Calvinia, south of these mountains. The flower size, especially dimensions of the tepals, confirms its status as a separate species allied to H. vaginata. Lastly, new collections o f the relatively uncommon, yellow-flowered variant of H. acuta show that this plant, confined to the eastem portion of the range of the species, differs consistently from the white-flowered form in several floral features, and it is raised to subspecies rank as H. acuta subsp.  tugwelliae.

Bioclimatic Variables

Twelve new species in a new genus, Geelus gen.n. are described, 10 species from a confined area in the north- and south-western parts of South Africa and two from Namibia. The genus has been recorded from 35 plant species in 18 families, with one species Geelus dundraad collected on Rooibos Tea, Aspalathus linearis (Fabaceae), which is indigenous to South Africa and cultivated commercially. The 12 new species are Geelus driehoekdraad sp.n., G. drietanddraad sp.n., G. dundraad sp.n., G. haakdraad sp.n., G. kinkeldraad sp.n., G. lemdraad sp.n., G. nektanddraad sp.n., G. platdraad sp.n., G. slangdraad sp.n., G. stompdraad sp.n., G. viertanddraad and G. vurkdraad sp.n. This new genus is allied to the Bonaspeiini, in the Deltocephalinae based on the broad lorum, apically expanded clypellus, dorsal side of the pygofer deeply and broadly incised, large sclerotized segment X, smooth merging of face and crown and Y-shaped connective with short stem. A MaxEnt distribution model based on 19 bioclimatic variables confirmed that the South African species occur within a confined region in the south-western parts of southern Africa.

A New Species

Carlisle (1954) described Styela mammiculata, a new species of stalked ascidian from the Plymouth area, and suggested that it had been brought into British waters, probably with oysters. Its recent discovery on other parts of the south coast of England (Houghton & Millar, 1960) supports the idea that it is an introduced species which is now spreading through a favourable environment. It is well, therefore, to consider whether this may not be a species known from another part of the world. Tokioka (1955) examined one of Carlisle's specimens and suggested that it fell within the range of variation of S. clava Herdman. As many specimens of S.mammiculata are now available, a more extensive comparison has been made and is reported in this paper.
