Schutte, A.L. 1995. Five new species of the genus Liparia (Fabaceae) from South Africa. - Nord. J. Bot. 15: 149–156. Copenhagen. ISSN 0107–055X.
Five distinct new species of the genus Liparia are described, namely L. bonaespei, L. confusa, L. congesta, L. rafnioides and L. triata . These species are, like many of the species included in the recently enlarged generic concept of Liparia , also localized, and are all endemic to the Cape Province of South Africa.     

Palystes kreutzmanni sp. n. - a new huntsman spider species from fynbos vegetation in Western Cape Province, South Africa (Araneae, Sparassidae, Palystinae

Palystes kreutzmannisp. n. is described from habitats close to Kleinmond, in the Western Cape Province, South Africa. Spiders of this new species live in the typical fynbos vegetation of the Western Cape region. They build retreats between apical leaves of Leucadendron bushes. The systematic position of Palystes kreutzmannisp. n. is discussed. Male and female show characters of different species groups, especially the female copulatory organ seems to be unique within the genus Palystes L. Koch, 1875.     

Acaulonopsis,a new moss genus of the Pottiaceae from Western Cape Province of South Africa,and comments on Vrolijkheidia

Abstract

A new genus, Acaulonopsis (Pottiaceae, Bryophyta), including two new species, A. fynbosensis and A. eureka, is described from the Western Cape Province of South Africa. Together with the similarly much reduced pottiaceous genus Acaulon, Acaulonopsis is unique in the family with a very short seta and spherical capsule, which lacks the apiculus found in other genera. The new genus is also distinguished by short plant stature, and a total of about five ovate leaves that clasp closely the capsules in nearly spherical leaf bases. Continuing bryological study of the fynbos region has recently resulted in a number of startling discoveries of bryophytes new to science and distinct at the genus level. A new combination is made for the South African endemic genus Vrolijkheidia (Pottiaceae) with discussion of its dimorphic habitus.     

The pennatulacean genus Cavernularia Valenciennes (Octocorallia: Veretillidae)

Two new species of sea pens referable to the genus Cavernularia Valenciennes are described from Natal and Transkei, east coast of southern Africa, at depths of 24 and 190 to over 300 m. The two new species are distinguished from other members of the genus by unique combinations of features regarding the axis, colonial growth form, autozooid size, as well as the size, shape, and distribution of sclerites. A comparative review of the genus is included. The 13 presently recognized worldwide species are differentiated and a key for their separation, together with a table of comparative characters, is provided. Of these, ten (77%) are Indo-Pacific in distribution whilst the remainder (23%) are presumably restricted to the eastern Atlantic. Four species are presently recorded from southern Africa. The deepest known bathymetric stations for the genus are here recorded from northern Namibia at 274 m, and from northern Natal at 310/320 m. Relationships to members of the related genus Cavernulina Kükenthal & Broch are discussed.     

Two new species of Askidiosperma (Restionaceae) from South Africa

Askidiosperma delicatulum , sp. nov., from the arid margins of the Cold Bokkeveld mountains in the Western Cape Province, South Africa, is described and illustrated. A. chartaceum ssp. alticolum is raised to specific level. A new key to the species in the genus Askidiosperma is provided.     

Paradiaptomus peninsularis, P. hameri and P. warreni, three new species of Paradiaptomus (Calanoida: Diaptomidae) from South Africa

Three new species of Paradiaptomus from southern Africa are described, Paradiaptomus peninsularis, P. hameri and P. warreni. Paradiaptomus peninsularis occurs in temporary blackwater pools on the peninsula of the Western Cape province, P. hameri in saline pools in the Western Cape province and P. warreni in mountain tarns in the Drakensberg Range in Kwazulu Natal and Lesotho. The genus Paradiaptomus was first established by Sars (1895) for Paradiaptomus lamellatus. There are five described species of Paradiaptomus endemic to Africa ( lamellatus, schultzei, similis, natalensis and rex) and P. greeni from India and Sri Lanka. The three new species have highly-weighted morphological characters which set them apart from each other and from any of the described species of Paradiaptomus.     

A new genus of soft coral of the family Alcyoniidae (Cnidaria, Octocorallia) with re-description of a new combination and description of a new species

A new genus, Aldersladum (family Alcyoniidae), is established to accommodate a previously described species, Efflatounaria sodwanae Benayahu, 1993 (family Xeniidae) from Sodwana Bay, South Africa that was wrongly assigned to the latter genus. This species is redescribed and a second new species, Aldersladum jengi from Penghu Is., Taiwan, is described. The diagnostic features of the new genus include the presence of only figure-eight shaped platelets in all parts of the colony, thus differentiating it from all known genera of the Alcyoniidae. Based on examination of additional material from other localities, the zoogeographical distribution of the genus is confirmed to include the coral reefs of South Africa, Kenya, Gulf of Oman, Taiwan and Japan. Phylogenetic analyses of two mitochondrial genes strongly support its placement in the family Alcyoniidae.     

A review of the alderfly genus Leptosialis Esben-Petersen (Megaloptera, Sialidae) with description of a new species from South Africa

The monotypic South African alderfly genus Leptosialis Esben-Petersen, 1920 is reviewed and Leptosialis africana Esben-Petersen, 1920 is redescribed. In the process a new species of alderfly Leptosialis necopinatasp. n. from the Eastern Cape and KwaZulu-Natal provinces of South Africa is recognised and described. Within Sialidae the new species most closely resembles Leptosialis africana. A key to the two species of Leptosialis using both adult and larval characters is provided.     

DIVERSIFICATION OF THE AFRICAN GENUS PROTEA (PROTEACEAE) IN THE CAPE BIODIVERSITY HOTSPOT AND BEYOND: EQUAL RATES IN DIFFERENT BIOMES

The Cape region of South Africa is a hotspot of flowering plant biodiversity. However, the reasons why levels of diversity and endemism are so high remain obscure. Here, we reconstructed phylogenetic relationships among species in the genus Protea, which has its center of species richness and endemism in the Cape, but also extends through tropical Africa as far as Eritrea and Angola. Contrary to previous views, the Cape is identified as the ancestral area for the radiation of the extant lineages: most species in subtropical and tropical Africa are derived from a single invasion of that region. Moreover, diversification rates have been similar within and outside the Cape region. Migration out of the Cape has opened up vast areas, but those lineages have not diversified as extensively at fine spatial scales as lineages in the Cape. Therefore, higher net rates of diversification do not explain the high diversity and endemism of Protea in the Cape. Instead, understanding why the Cape is so diverse requires an explanation for how Cape species are able to diverge and persist at such small spatial scales.     

Paraquimperia Africana n. sp (Nematoda : Quimperiidae), a new intestinal parasite of the eel Anguilla mossambica Peters, in South Africa

A new seuratoid nematode of the family Quimperiidae, Paraquimperia africana n. sp., is described from the small intestine of the longfin eel, Anguilla mossambica Peters, from the Eastern Cape Province, South Africa. The new species is characterized mainly by the presence of a ventral sucker in mature males, short spicules (147-171 microm), the number and arrangement of caudal papillae, the postesophageal position of the excretory pore, and by the slender female tail. In this new species, a variability in the number (3-5 pairs) of subventral preanal papillae was observed. Paraquimperia africana is the first representative of the genus in Africa. In view of recent reports, Paraquimperia aditum (Mueller, 1934) is considered a junior synonym of Paraquimperia tenerrima (Linstow, 1878). Paraquimperia xenentodonia Gupta and Bakshi, 1984 is considered a species inquirenda.     

The genus Ectonura Cassagnau, 1980in South Africa (Collembola, Neanuridae, Neanurinae), with a key to South African Neanurinae

Two new species of Neanurinae (Collembola) are described from the Western Cape, South Africa: Ectonura monochaetasp. n. and Ectonura barraisp. n.Ectonura monochaetasp. n. differs from other species in the genus by its strongly reduced chaetotaxy, and the lateral shift of dorso-internal chaetae on Abd. V and their integration in the tubercles (De+DL). Ectonura barraisp. n. is similar to Ectonura natalensis (Womersley, 1934), but differs in chaetotaxic details and chaetal group arrangement. A key to the seven species of Neanurinae recorded from South Africa is given.     

The taxonomy and affinities of Papaver gorgoneum from the Cape Verde Islands

A new subspecies of Papaver gorgoneum , ssp. theresias is described from the Cape Verde Islands, West Africa. A detailed comparison of the 2 subspecies is made and the ecology, the affinities of the species in the genus and the origin are discussed. The chromosome numbers of both subspecies (2n = 38) are reported for the first time and a note on the compatibility system is made.     

A new genus and three new species of cockroaches (Blattaria: Dictyoptera) from Africa

A new genus Princisaria belonging to family Blaberidae is described from Africa. A key to the African genera of the subfamily Laxatinae is given. Three new species, P. carvalhoi, P. ugandana and P. curta are described.     

Eight new species of Marasmodes (Asteraceae,Anthemideae) from South Africa

During a stay at the Kirstenbosch Research Centre in Cape Town (South Africa), several groups of Asteraceae were studied. One of these was the genus Marasmodes (tribe Anthemideae). After a careful taxonomic study of additional material, including the first species described by A. P. de Candolle, the author has concluded that eight collections should be considered as new species. These new species are described and their relationships with the most similar species of the genus are discussed. © 2009 The Linnean Society of London, Botanical Journal of the Linnean Society, 2009, 159 , 330–342.     

A new genus and species of a dendrochirotid holothurian from Southern Africa

A new genus and species of a dendrochirotid holothurian, Pawsonellus africanus , from shallow waters off the east coast of Southern Africa, are described. The new genus is compared with several genera within the family Cucumariidae and it is concluded that it is not closely related to any of them. Although its body wall spicules strongly resemble those of Panningia hyndmani (Thompson), notably the typical form described by Madsen (1942), there are several features which suggest that the two species are not congeneric.     

Revision of the umbellatarum species group of Anthaxia (Coleoptera: Buprestidae)

Abstract. The umbellatarum species group of the genus Anthaxia Eschscholtz of the Mediterranean region is characterized. A key is provided to distinguish this group from some superficially similar groups occurring in the same region, and to the five species and one subspecies referable to the group. Two new species, scylla and hamata are described. A.inculta ab. boissyi Obenberger is recognized as a distinct species and a lectotype is designated. A.domina Abeille is made a subspecies of umbellatarum (Fabricius). A.inculta ab. karamani Obenberger is found to be a colour form of cichorii (Olivier), not of umbellatarum as previously regarded. The other species belonging to the group is lusitanica Obenberger. All species belonging to the group are described.
