Two new combinations are made for taxa that were previously attributed to the genus Schizoglossum and are now placed in the genus Stenostelma. Included is the typification of Stenostelma capense, S. carinatum, S. corniculatum, S. eustegioides and S. periglossoides. Two new species, Stenostelma ligulatum and S. urceolatum, both with restricted distributions, are described here. Preliminary conservation assessments (Red List status) for the newly described taxa are provided.

Two new species of Brownanthus, B glareicola Klak and B fratemus Klak and one new species of Scopelogena, S. bruynsii Klak are described. S. gracilis L.Bolus is reduced to synonymy under S. verruculata (L.) L Bolus. Three new combinations are made: Antimima excedens (L.Bolus) Klak. Erepsia dunensis (Sond.) Klak and Hammeria meleagris (L.Bolus) Klak and full synonomy is given  Lampranthus maximilianii (Schltr. A.Berger) L Bolus is transferred back to Braunsia maximilianii (Schltr. A Berger) Schwantes and the identity of Ruschia polita L Bolus is discussed. The taxonomic position of Mesembryanthemum purpureostylum L.Bolus is clarified.

In The Wild

Sisyranthus species are cryptic in both their habit and small size of their flowers making them difficult to find in the wild. The genus was last revised in Flora Capensis (1908) and since then, two new species have been described. Currently it comprises 13 recognised species endemic to southern Africa. Many of these are range-restricted and poorly known. In this contribution the genus is further expanded by describing two novel species. Full descriptions, assessment of conservation status, distribution maps and line drawings of the new taxa are presented.

Two New Species

Sampling of remote inland aquatic habitats in South Africa has constantly been yielding novel endemic freshwater crab species (Potamonautes MacLeay,1838). During the present study, we report on the discovery and description of two new freshwater crab species (Potamonautes baziya sp. nov., and P. mariepskoppie sp. nov.) from Afrotemperate forested mountain regions in the Eastern Cape and Mpumalanga provinces of South Africa, respectively. Phylogenetic evidence derived from DNA sequence data of three partial mitochondrial loci (12S rRNA, 16S rRNA and cytochrome oxidase subunit one, COI) corroborates the evolutionary distinction of the two novel species. In addition, morphological and ecological data for the two new species further delineate their evolutionary distinction from congeneric sister species. A comparison of the taxonomically important gonopods 1 and 2 and carapace features among the sister species and other known freshwater crabs of South Africa was further used to provide evidence for the distinction of the two novel species. The discovery of two new species suggest that remote mountainous areas or unsampled regions in South Africa likely harbor several novel species, reiterating a call to document aquatic inland biodiversity in forested and mountainous regions of the country.

AbstractFive species of the subfamily Acrolobinae, viz. Panagrolobus vanmegenae gen. n., sp. n., Teratolobus regulus Andrássy, 1968, T. obscurus sp. n., T. hamatus (Andrássy, 1986) comb. n. and T. similis sp. n., are described and illustrated from material collected in The Netherlands, Ukraine, Costa Rica, Mexico, Australia and South Africa. The new genus is characterised by a crown-shaped labial region with six well-developed, leaf-like lips having a biradial symmetry; lips separated by narrow and internally sclerotised U-shaped clefts; lateral lips half as wide as the subdorsal and subventral ones; a broad anisomorphic stoma; strongly sclerotised, hookshaped, cheilorhabdia; a strongly developed dorsal prostegorhabdion extending inside the stegostom cavity; a conoid tail with a rounded terminus bearing a dorsally curved, hook-like, mucro; and phasmids located at 70-90% of tail length. Teratolobus obscurus sp. n. is distinguished from the closely related T. regulus by the following characters: a smaller spermatheca (7.0-14.5 vs 26-61 μm); a shorter PUB (12-19 vs 18-42 μm); a shorter female tail (42-50 vs 55-72 μm); and differently shaped mucro on the tail terminus (harpoon-like vs hook-like). Teratolobus similis sp. n. is distinguished from the closely related T. baloghi (Andrássy, 1986) comb. n. by the following characters: a smaller body (350-420 vs 470-480 μm); a shorter PUB (9-12 vs 35-38 μm; 0.5-0.8 vs ca. 2 VBD long); shorter female tail (41-53 vs 62-65 μm; c′ = 3.4-5.4 vs 6.5-7.0); and differently shaped mucro on the tail terminus (arrowhead-like vs finely forked). Based on current research, a revision is proposed of the taxonomy of the genus Teratolobus and the subfamily Acrolobinae. The following new combinations are proposed: Teratolobus baloghi; T. hamatus; and T. occultus (De Ley & Coomans, 1990) comb. n. Panagroteratus is proposed as a synonym of Teratolobus.

Two new species of South African Syllidae of the genusSyllisLamarck, 1818 are described.Syllis unzimasp. nov. is characterized by having unidentate compound chaetae with long spines on margin, a characteristic colour pattern and its reproduction by vivipary. Vivipary is not common among the polychaetes, but most representatives occur in the family Syllidae Grube, 1850 (in five otherSyllisspecies, two species ofDentatisyllisPerkins, 1981 and two species ofParexogoneMesnil & Caullery, 1818).Syllis unzimasp. nov. differs from the other viviparous species in having large broods (>44 juveniles) which develop synchronously. Development of the juveniles is similar to that of free-spawningSyllisspecies, but the appearance of the first pair of eyespots and the differentiation of the pharynx and proventricle occur later inS. unzima.Syllis amicarmillarissp. nov., is characterized by having an elongated body with relatively short, fusiform dorsal cirri and the presence of one or two pseudosimple chaeta on midbody parapodia by loss of blade and enlargement of shaft.Syllis unzimasp. nov. was found in high densities on culturedHolothuria scabraJaeger, 1833 with single specimens found on a culturedCrassostrea gigasThunberg, 1793 and on coralline algae, respectively, whileS. amicarmillariswas found mainly in sediment outside an abalone farm and less frequently on culturedHaliotis midaeLinnaeus, 1758. We discuss the possible benefits of the association withH. scabratoS. unzimasp. nov.

Abstract. The stratigraphic distribution of the Late Callovian to Early Oxfordian dinoflagellate cyst Stephanelytron Sarjeant 1961 emend provides new evidence pertaining to its evolution. Middle and Upper Callovian times favoured the development of speciations to a short-ranging Stephanelytron community with corona(s) in ventral–posterior position (Stephanelytron brontes, S. callovianum, S. ceto and S. tabulophorum) from eurytopic species with antapical coronas (S. caytonense, S. membranoidium, S. redcliffense and S. scarburghense). The former group of species (except S. tabulophorum) may represent an example of peripatric speciation from an unfavourable mutation. The reduced stratigraphic range gives the appearance of an endemic population. The genus Lagenadinium Piel, 1985 is a junior synonym of Stephanelytron Sarjeant, 1961. A new emendation of Stephanelytron, two new combinations (S. callovianum and S. membranoidium) and two new species (?S. brontes and S. ceto) are proposed.
