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.

The Family

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.

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).

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.

A recent major revision of the Family Latrunculiidae (Demospongiae: Poecilosclerida) recognised four valid genera; Latrunculia du Bocage, Sceptrella Schmidt, Strongylodesma Lévi, and Tsitsikamma Samaai & Kelly, from South Africa. The major diagnostic characters of the Family Latrunculiidae are the possession of discate acanthose microrhabd microscleres called acanthodiscorhabds, or more traditionally, “chessman” spicules, that form a dense palisade in the outer ectosome, a tangential layer of styles or anisostrongyle megascleres below this, and a wispy choanosomal skeleton of the same spicules. The sponge surface almost always has areolate porefields and short fistular oscules. This paper reports new Latrunculiidae from western and southeastern South Africa, including a redescription of Latrunculia biformis (Kirkpatrick). Four key characters, including microsclere ornamentation, spicule dimensions, colouration in life, and surface aquiferous features, define three new species of Latrunculia (L. lunaviridis sp. nov., L. microacanthoxea sp. nov., and L. bellae sp. nov.), two new species of Strongylodesma (S. algoaensis sp. nov. and S. tsitsikammaensis sp. nov.), and two new species of Tsitsikamma (T. pedunculata sp. nov. and T. scurra sp. nov.).

Two New Species

The Australian members of the vetigastropod family Anatomidae are revised and two new species are described. The family has thus far been treated as a subfamily of Scissurellidae, but recent molecular evidence (Geiger & Thacker, unpubl. data) indicates that Scissurellinae plus Anatominaeis not monophyletic, and full family rank is warranted for a group containing the genera Anatoma and Thieleella. Seven species from Australia belonging in Anatomidae are discussed and illustrated by SEM: Anatoma aupouria (Powell, 1937) mainly from New Zealand, though with some Australian records; A. australis (Hedley, 1903), A. funiculata n. sp., An turbinata (A. Adams, 1862), which has been misidentified in the past as the South African A. agulhasensis (Thiele, 1925), A. tobeyoides n. sp., Thieleella equatoria (Hedley, 1899) with a second known specimen, and T. gunteri (Cotton & Godfrey, 1933). Other species that have been (erroneously) indicated from Australia are discussed. A neotype is designated for A. agulhasensis from South Africa for taxon stabilization.
