The genus Tsitsikamma Samaai & Kelly, 2002 is to date exclusively reported from South Africa. Three species are known from the southern coast: Tsitsikamma favus Samaai & Kelly, 2002, from the Garden Route National Park Tsitsikamma Marine Protected Area (MPA) and Algoa Bay; T. pedunculata Samaai, Gibbons, Kelly and Davies-Coleman, 2003, collected from Cape Recife in St. Francis Bay, and T. scurra Samaai, Gibbons, Kelly and Davies-Coleman, 2003, collected from a wreck site in a small bay west of Hout Bay on the west coast of South Africa. Here two new species are described: Tsitsikamma michaeli Parker-Nance, sp. nov., a small green purse-like species, collected from Algoa Bay, and Tsitsikamma nguni Parker-Nance, sp. nov., from The Garden Route National Park, Tsitsikamma MPA. Additional morphological characteristics, spicule morphology, and distribution records are provided for T. favus and T. pedunculata from Algoa Bay. The phylogenetic relationship of these five Tsitsikamma species is investigated.

Two new multifoliolate species of Oxalis L. (Oxalidaceae) from the Hantam Karoo region of South Africa are described and illustrated: Oxalis carolina and O. filifoliolata. Both species occur in single populations in the extremely geophyte-rich area on the Bokkeveld Plateau in the Northern Cape Province. Morphological characteristics, phylogenetic position, habitat description and conservation status of the new species are provided, in addition to a diagnostic comparison with other phenotypically similar Cape species. Fifteen multifoliolate Oxalis species are currently recognized in South Africa, disregarding multifoliolate varieties of otherwise trifoliolate species. A key for multifoliolate Oxalis species known from the Bokkeveld Plateau is presented.

The praying mantis subgenus Syngalepsus Beier, 1954 occurs in sub-Saharan region and represents the least diverse subgenus of Galepsus in Africa (Ehrmann 2002). All species included within the subgenus Syngalepsus are comprehensively revised with a distribution stretching from North of Congo Basin to South Africa. Two new species of Galepsus (Syngalepsus) Beier, 1954 (Mantodea, Tarachodidae) from the Central African Republic (CAR) and Malawi are described. Among several Galepsus specimens collected during scientific expeditions of SANGHA, Biodiversité en Terre Pygmée, in CAR’s Dzanga-Ndoki National Park, a specimen differed by genitalia conformation and other morphological characters. Two specimens collected in Malawi proved to differ by genitalia morphology. Galepsus (Syngalepsus) buchetisp. n. and Galepsus (Syngalepsus) dudleyisp. n. are described. An identification key for the six species of the subgenus is provided.

Two new Oxalis species from the Richtersveld National Park (South Africa) are described and typified. Both species show strong morphological resemblance to members of the South African Oxalis section Cernuae. Oxalis nivea sp. nov. closely resembles the well-known weed O. pes-caprae, but it bears white flowers, and has a very restricted distribution range north of the northernmost known locality of O. pes-caprae. Oxalis rosettifolia sp. nov. is distinguished from all other species by a combination of a flat basal rosette of leaves, terete petioles, flask-shaped floral tubes and at least some enlarged, spathulate bracts at the terminal articulation of the peduncle. Phylogenetic analyses based on nuclear ITS and plastid trnSG data confirmed the placement of both of these species within a clade containing O. pes-caprae. The exact placement of these two species differs between ITS- and trnSG-based trees, but both analyses confirm a close relationship between the two new species and O. copiosa and O. cf. haedulipes.

Two new species of the ant genus Myrmecina Curtis, 1829 are described and illustrated based on the worker and queen castes collected in Sumatra, Indonesia under the names M. andalas sp. nov. and M. nitidiuscula sp. nov. Each species displays unique morphological characteristics. Myrmecina andalas sp. nov. is characterized by a combination of the following characteristics: head dorsally sculptured, with the ventrolateral area smooth and shiny; propodeal spine short, triangular, pointing dorsad and with a broad base; propodeal declivity vertical, with the posterodorsal angle almost 90°. Myrmecina nitidiuscula sp. nov. is characterized by a combination of the following characteristics: head dorsum largely smooth and shiny; propodeal spine triangular and pointing posteriad, with a very broad base. Updated key to Myrmecina species of Sumatra is given.

A New Species

The Chorthippus biguttulus group distributed in the west Palaearctic, while intensively examined in Europe, is poorly known in the glacial refugia such as Anatolia. This produces constraints in making accurate statements about evolution and the biogeography of the group. The C. brunneus subgroup of this lineage is examined using large amounts of morphological and song data from Anatolia (Asian Turkey) and representatives from Europe. Song and morphology in combination suggested three species to be found in Anatolia. The first is C. bornhalmi Harz which is also known from south-east Europe. The other two are new species: Chorthippus antecessor sp. n. and Chorthippus relicticus sp. n.. Morphologically, C. antecessor sp. n. is the most aberrant species of the C. brunneus subgroup, but is similar to C. bornhalmi in song. The specific song and morphology (the aberrant number of stridulatory pegs) define C. relicticus as a new species and both also indicate that it is closely related to C. brunneus and C. jacobsi. A song and morphology based phyloylogenetic assumption for C. brunneus subgroup suggests C. antecessor, C. bornhalmi and C. miramae to constitute one clade and C. brunneus, C. jacobsi and C. relicticus another. The scenario suggested for their evolution assume the following steps: (i) divergence of C. bornhalmi from a C. antecessor like ancestor, (ii) derivation of an ancestral population (which later give rise to C. brunneus + C. jacobsi + C. relicticus) from a C. bornhalmi like ancestor, and (iii) later fragmentation of this ancestral population to result in the present three species (C. brunneus + C. jacobsi + C. relicticus). All of these events seem to be correlated with the climatic cycles during Pleistocene. The conclusion is that the two new species are range-restricted, vulnerable species as is the case for many other taxa present in the Mediterranean Taurus biodiversity hotspot.

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.
