A New Species

The new species Streptocarpus lilliputana (Gesneriaceae), collected on the Pondoland coast, South Africa, is described. Although its alliances are not obvious in terms of corolla morphology and rosulate habit, it approaches S. gardenii and its allies. The pollen and stigma of S. lilliputana differ markedly from the stenopalynous grains and bilobed stigmas of the other South African rosulate species. Streptocarpus lilliputana is exceedingly rare and is a further endemic from the Pondoland centre.

Characteristic Colour

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.

A New Species

A new species of Obuloides, Obuloides crinitus sp. nov., is described based on females and males collected from the galls and twigs of Grewia occidentalis (Tiliaceae) in South Africa. Obuloides crinutus is closely related to O. namibiensis and O. rajamohani but can be distinguished by the finely granulated shields, a character that no other species of this genus has. Another notable difference is the length of prodorsal setae v2, which are longer and more strongly serrated compared to the other species of this genus which have very short and mostly smooth setae. Males of this species lack setae d1. A key to known species is provided.

Trechodes intermedia sp. nov. and T. kogelbergensis sp. nov. are described from South Africa. A third species, T. humeralis (Jeannel, 1930) comb.nov. is transferred to Trechosia Jeannel from the genus Cothresia Jeannel. All three species are macropterous, endemic to the South African Cape region, and together represent a new species group of the genus Trechosia. Keys to the species groups of the genus Trechosia and to the species of the new T. intermedia group are provided.

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.

A New Species

A new South African species of the genus Chaperiopsis is described from material deposited in the Muséum National d'Histoire Naturelle, Paris. Chaperiopsis stephensoni is redescribed and figured from the original material.The genus Chaperiopsis Uttley, 1949 is widely distributed in the southern hemisphere. Numerous species of this genus have been described in different works; notable amongst these are the works of Busk (1854, 1884), Kluge (1914), Uttley (1949), Gordon (1984), Hayward & Thorpe (1988), Reverter Gil & Fernández Pulpeiro (1995) and Hayward (1995). Some previous records of Chaperiopsis spp. from South Africa are included in the works of Jullien (1881), Busk (1884), O'Donoghue & De Watteville (1935), O'Donoghue (1957) and Hayward & Cook (1983).

A New Species

During the examination of the rich collections of the genus, Rhynchosia housed in some South African herbaria (BNRH, NH, PRE), a new and yet to be described species was discovered. The species is similar to R. pauciflora in its erect habit, linear or oblong leaflets, and solitary flowers. The study is based on the examination of herbarium specimens. Measurements were taken from vegetative and reproductive parts. We describe here R. ngwenyii. The new species differs from R. pauciflora by its broader (24–38 mm), linear-lanceolate to oblong-lanceolate terminal leaflets that are without conspicuous revolute margins, wing petals that lack sculpturing and shorter peduncles, (25)30–42 mm. It is distributed in KwaZulu-Natal and Mpumalanga Provinces in South Africa. The preliminary conservation status is evaluated as Endangered. A detailed description, illustration, distribution map, and the information on ecology, as well as phenology are also presented.

African Genus

Sixteen species of Latrunculiidae Topsent, 1922, belonging to the genera Latrunculia du Bocage, 1869, Strongylodesma Lévi, 1969, Cyclacanthia Samaai & Kelly, 2004, Samaai & Kelly, 2002, are currently known from the temperate waters of South Africa. Extensive new sponge collections from the Amathole region of South Africa revealed the existence of three new species of Tsitsikamma, T. amatholensis sp. nov., T. madiba sp. nov., and T. beukesi sp. nov., and a new species of the endemic South African genus Cyclacanthia, C. rethahofmeyri sp. nov. With the recent addition of two new species of Tsitsikamma from Algoa Bay and Tsitsikamma National Park (T. michaeli Parker-Nance, 2019; T. nguni Parker-Nance, 2019) the total number of known South African Latrunculiidae is now 20 species in four genera. Here we propose two new subgenera of Tsitsikamma, Tsitsikamma Samaai & Kelly, 2002 and Clavicaulis subgen. nov., based on the morphological groups “favus” and “pedunculata” hypothesized by Parker-Nance et al. (2019). Species in the nominotypical subgenus Tsitsikamma, containing the type species, are thick encrusting to hemispherical with a rigid honeycombed choanosome, while species in the new subgenus Clavicaulis subgen. nov. have a purse or sac-like morphology with little choanosomal structure. Despite the obvious species-level differences in morphology, multivariate analysis based on spicule measurements (anisostyle length, discorhabd length, shaft and whorl length) was not able to distinguish between the proposed Tsitsikamma species, but separated known species T. favus Samaai & Kelly, 2002, T. pedunculata Samaai & Kelly, 2003, and T. scurra Samaai & Kelly, 2003, from each other. Similarly, DNA barcoding of the mitochondrial COI  and the nuclear ITS of Tsitsikamma specimens failed to clearly differentiate between species, but was able to differentiate sister taxon relationships within the Latrunculiidae.

A New Species

AbstractA new species, Paradiplozoon ichthyoxanthon (Monogenea: Diplozoidae) is described from the gills of Labeobarbus aeneus (Cyprinidae) in the Vaal Dam and Vaal River Barrage in the Vaal River, South Africa. This species is the first in this genus from southern Africa; Paradiplozoon aegtyptense and Paradiplozoon ghanense have been described from northern Africa. The new species differs from all other Paradiplozoon species on the basis of the combination of morphological characteristics, namely disk-like haptor, eggs without filaments, clamp and central hook morphology and size of specimens. The species description is accompanied by a description of the reproductive organs. The internal transcribed spacer of the ribosomal gene (ITS2) was studied and the South African individuals formed a distinct clade, supporting the establishment of a new species.

The South African Peripatopsidae comprise two genera: Peripatopsis Pocock, 1894 (eight described species) and Opisthopatus Purcell, 1899 (two described species, and three subspecies currently debated). Recent collecting in South Africa produced a new and unusual onychophoran, Opisthopatus herbertorum sp. nov., from Mt. Currie Nature Reserve, KwaZulu-Natal. The new species is characterised by 17 pairs of legs, 15 complete dorsal plical folds per body segment, a lack of body-pigmentation, and reduced eyes. A key to the three species of Opisthopatus is provided. Other species of white onychophorans have been identified in South Africa, Australia and Jamaica; some of these species are cave-dwellers. The discovery of O. herbertorum sp. nov. from a small, isolated forest patch means that this species may be threatened with extinction, mainly through fire or other stochastic events. The habitat contains species of myriapods typical of forests, which suggests that the fauna is relictual, and that small forest patches have high conservation value. The discovery of the new species also highlights the lack of knowledge about forest invertebrates in South Africa, and raises the possibility of a far greater onychophoran diversity in the country.
