Five new species ofMaurotarionAlberti, 1969 from the Silurian Lipeón Formation and Lower Devonian Talacasto Formation of Argentina are recognized. The comparisons with Bolivian and South African species support a Malvinokaffric clade based on librigenal synapomorphies, here erected asMaurotarion(Malvinotarion) new subgenus. The Malvinokaffric origin of the family would not be a migration from lower paleolatitudes but an Early Silurian stock of rare cosmopolitan ancestors which underwent a great Devonian radiation. Two lineages can be recognized within MalvinokaffricMaurotarion.The Silurian-Pragiandereimsilineage is a plesiomorphic one resembling Silurian representatives and involvesM.(Malvinotarion)dereimsi, M.(Malvinotarion)talacastoensenew species,M.(Malvinotarion?) new species A,M.(Malvinotarion?) new species B,M.(Malvinotarion) sp., and eventuallyM. (Malvinotarion?)cf.dereimsi.Theisaacsonilineage ranges from the Lower Pragian to Eifelian exhibiting a defined morphologic trend in the librigena. This lineage comprisesM.(Malvinotarion)isaacsoni, M.(Malvinotarion) sp. A from South Africa,M.(Malvinotarion)gauchonew species,M.(Malvinotarion)haudeinew species andM.(Malvinotarion)legrandi.A Lochkovian diversification probably took place yet an adequate assessment remains difficult. In contrast, a great evolutionary burst is recognized during the Emsian and is related to Pragian-Emsian global relative sea level curves which are coincident with those proposed from Bolivian and Argentinian basins.

The Family

The recently described family Chummidae, now the sister clade of Macrobuninae, so far only known from two South African species, is extended with seven new species, six from the southern part of South Africa and one from Lesotho: Chumma bicolor sp. nov. (♀), C. foliata sp. nov. (♂♀), C. interfluvialis sp. nov. (♂♀), C. lesotho sp. nov. (♀), C. striata sp. nov. (♂♀), C. subridens sp. nov. (♂♀) and C. tsitsikamma sp. nov. ♂. A key to the species is provided. Although Chumma is part of a clade containing the Macrobuninae, it is argued that the family name Chummidae should remain valid.

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.

Two new species of the genus Paragus Latreille, 1804 are described from the Republic of South Africa: Paragus longipilus Tot, Vujić et Radenković sp. nov. and Paragus megacercus Tot, Vujić et Radenković sp. nov. These new species belong to the subgenus Pandasyopthalmus Stuckenberg, 1954a. Paragus longipilus sp. nov. is a member of the P. jozanus group, whereas Paragus megacercus sp. nov. belongs to the P. tibialis group. The taxonomic status of Paragus chalybeatus Hull, 1964 is revised and proposed as synonym of Paragus punctatus Hull, 1949. Additionally, an identification key to males of the South African species of Paragus is provided. Results of the present study confirm a significant level of endemism of Paragus in the Afrotropical Region (12 out of 29).

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).

Species of the genera of the Cryptopygus complex in South Africa are morphologically revised. Five new species of the genus Cryptopygus Willem, 1902 s. s. and one new species of the genus Isotominella Delamare Deboutteville, 1948 are described. Cryptopygus abulbussp. nov. and C. bulbussp. nov. have only one chaeta on the anterior side of dens and no chaetae on the anterior side of manubrium, the latter species being characterized by the presence of a bulb at apex of antennae; C. inflatussp. nov. shows a rare combination of eight ocelli on each side of the head with a tridentate mucro; C. longisensillussp. nov. has five long s-chaetae on the fifth abdominal segment; C. postantennalissp. nov. is unique by having a very long and slender postantennal organ with strong inner denticles; Isotominella laterochaetasp. nov. is the second member of the genus and differs from the type species by many more anterior chaetae on the manubrium and the presence of chaetae on ventral side of metathorax. The genera are discussed and a key to all species of the Cryptopygus complex recorded in South Africa is given. The focus is on the Western Cape Province where the complex is the most diverse and sampling more complete than in other provinces of South Africa.

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.
