Twenty three genera and 228 species of the millipede order Spirostreptida are currently known from Southern Africa. Non-specialists face considerable problems in identifying spirostreptidan millipedes even to generic level. This publication provides an illustrated and annotated key to the genera of the four families of spirostreptidans (Julornorphidae, Spirostreptidae, Harpagophoridae and Odontopygidae) represented in Africa south of the Zambezi and Kunene Rivers. Data on diversity within each genus and its distribution in and outside of Southern Africa are provided, as are references for keys to species where these exist.
A review of the South African species of Opomyzidae (Diptera: Schizophora), with description of a new species of Opomyza FallÃ©nSource: Annals of the Natal Museum 40, pp 23 –30 (1999)More Less
The Southern African fauna of Opomyzidae is reviewed, new material is recorded, and a new species of Opomyza FallÃ©n is descriptionbed from South Africa. The Southern African species of Opomyzidae are: Opomyza australis Stuckenberg, 1963: O. capensis Stuckenberg, 1963; and O. milleri sp. n., all of which are restricted to the southern and western Cape. A key to the species is presented. The distribution of the Opomyzidae in the Afrotropics and Southern Africa is discussed.

The world fauna of the rarely collected family Neminidae, and the known biology of some of its species are reviewed. The apparent rarity and recognition of the southern Africa species are discussed. A key to the two southern African genera and four species is presented. Ningulus simatus McAlpine, 1983 (Eastern Cape, South Africa) is redescriptionbed based on additional material. Ningulus macalpinei sp. n. (collected from the leaves of Strelitzia nicolai Regel & Koern), is descriptionbed from the Chimanimani Mountains of eastern Zimbabwe. The genus Nemo McAlpine, 1983, is recorded from the Afrotropical Region for the first time; two new species are descriptionbed: N. capensis from the southwestern Eastern Cape coast and N. zuluensis (collected from the leaves of S. nicolai) from the northern KwaZulu-Natal coast. Unique character states of southern African Nemo species are discussed. Dorsal and profile views of the head, and the wing, and the male terminalia, are illustrated for each species.
Afrotropical Asilidae (Diptera) 31. A review of the genera Stenopogon Loew, 1847 and Rhacholaemus Hermann, 1907 with the description of the new genera and species (Stenopogoninae)Author Jason G.H. LondtSource: Annals of the Natal Museum 40, pp 47 –82 (1999)More Less
In revising the afrotropical genera Stenopogon and Rhacholaemus new taxa have been descriptionbed and taxonomic changes made: New genera: Afroscleropogon (Genotype Dasypogon dilutus Walker, 1851); Haroldia (Genotype Stenopogon trivialis Oldroyd, 1974). New species: Afroscleropogon: bullingtoni, clementsi, lavignei, nagatomii; Haroldia: oldroydi; Rhacholaemus: artigasi, fisheri, grimmi, hradshyi, josephi, nelsoni, tsacasi; Stenopogon: lehri. New combinations: Transferred to Afroscleropogon: armatus (from Stenopogon), braunsi (from Stenopogon), dilutus (from Dasypogon). Transferred to Haroldia: trivialis (from Stenopogon). Transferred to Rhacholaemus: antigenes (from Dasypogon). New Synonyms: Stenopogon atrox Oldroyd, 1974 and S. compactus Oldroyd, 1974 = Rhacholaemus variabilis Hermann, 1907. Lectotype designation: Rhacholaemus variabilis Hermann, 1907. Keys to the genera of afrotropical Stenopogoninae and the species of Afroscleropogon, Haroldia and Rhacholaemus are provided. Only one species of Stenopogon is believed to be present in the Afrotropics - the newly descriptionbed S. lehri. The distributions and systematic positions of taxa are discussed.

Prosopantrum acrostichale sp. n. (Nigeria), P. congolense sp. n. (Republic of Congo) and P. demeteri sp. n. (Nigeria) are descriptionbed. A generic diagnosis is given and a key is presented for the identification of the four species known from sub-Saharan Africa. Some pecularities of the male and female genitalia of Cnemospathididae are stressed.

The Afromontane species of Wiedemannia Zetterstedt from East Africa are reviewed. Clinocera aquatica (Becker) is reclassified as Wiedemannia aquatica (Becker) comb. n., and W. kenyae sp. n. from Mt Kenya is descriptionbed. The species of the Ruwenzori Range and those of Mt Kenya form two distinct groups, with the former group considered most closely related to Southern African species. Additional biogeographic patterns and relationships with Southern African species are detailed.

The Clinocerinae of Southern Africa are reviewed and include six genera and 14 species. A primitive genus, Afroclinocera gen. n. and two new species (obesa and pecki) are descriptionbed and the new genus is considered the sister genus of the South American and Australian genus Proagomyia Collin. The first Southern African record of Roederiodes Coquillett (R. bifidus sp. n.) is reported. Two new species of Clinocera (smithi and adesa) together with C. tripunctata Smith are the only species of this genus in Africa and represent a previously unrecognised species-group. The male of Dolichocephala duodecempunctata Smith is descriptionbed, and additional records of other clinocerine species are provided. Keys to genera and species and illustrations of male terminalia are included. The phylogenetic relationships of all Southern African genera and/or species of Clinocerinae are discussed.
A new species of Lampromyia Macquart, from Oman: the first record of Vermileonidae (Diptera) from the Arabian PeninsulaSource: Annals of the Natal Museum 40, pp 127 –136 (1999)More Less
A descriptionption is given of Lampromyia umbraticola sp. n., discovered in the Hajar Mountains of northern Oman. This distinctive species is phylogenetically isolated and constitutes a monospecific species-group. The wide but fragmented range of Lampromyia Macquart, 1835, suggests that this genus is a relict of an old African fauna, and that it was distributed across the Saharan and Arabian areas before their aridification.

An account is given of the fossil insects of the Beaufort Group (Late Permian) investigated since the last publication by Riek (1976). The Odonata and Trichoptera are reported for the first time; specimens are assigned to three known genera not previously recorded in South Africa; eight new species are descriptionbed, two in new genera. The new taxa are as follows. Megasecoptera: Karoohymen minutus sp. n.; Homoptera: Permocicada thompsoni sp. n., Stenotegmocicada triclades gen. n. et sp. n., Afrostenivicia rediae gen. n. et sp. n.; Mecoptera: Callietheira granthami sp. n., Prochoristella balgowanensis and P. bulwerensis spp. n., Neochoristella goodalli sp. n. Several previously descriptionbed taxa are recorded from additional sites.
A review of the genus Burnupena Iredale, 1918 (Gastropoda: Buccinidae), with descriptions of two new speciesAuthor G.M. Dempster, Y. & BranchSource: Annals of the Natal Museum 40, pp 173 –204 (1999)More Less
The southern African genus Burnupena lredale, 1918, in the gastropod family Buccinidae has presented ongoing taxonomic problems because of morphological plasticity and the existence of forms that are intermediate between species. Based on morphological and genetic analyses, seven species can be recognised. In this paper we provide taxonomic descriptionptions of these species, including the merging of two previously recognised species as subspecies (Burnupena cincta cincta (RÃ¶ding, 1798) and B. cincta limbosa (Lamarck, 1822)), and the recognition and descriptionption of two new species (B. rotunda and B. denseliriata).
South African Mollusca described by Ferdinand Krauss: their current status and notes on type material housed in the Naturhistorika Riksmuseet, StockholmAuthor A.** Herbert, D.G.* & WarÃ©nSource: Annals of the Natal Museum 40, pp 205 –243 (1999)More Less
A complete alphabetical list of all South African taxa descriptionbed by Ferdinand Krauss is provided. The bulk of Krauss's type material housed in the Stuttgart Museum was lost during World War II, but important holdings of original Krauss material remain in the Swedish Museum of Natural History [Naturhistoriska Riksmuseet], Stockholm. Much of this was collected by the Swede, Johan Wahlberg. The validity and status of this as type material is discussed, together with the presently accepted taxonomic standing and generic relationships of the taxa. Type material of 54 Kraussian taxa has been located in Stockholm. The existence of additional type material in other institutions, or the possibility thereof, is also indicated. Diodora kraussi is proposed as a nomen novum for Fissurella australis Krauss, 1848 [non Philippi, 1845].

Nine species of the genera Nucula Lamarck, 1799, Ennucula Iredale, 1931, and Brevinucula Thiele, 1934, are here recorded from southern Africa and Mozambique. The sole Mozambican species is Nucula (Lamellinucula) semen Thiele, 1931, which occurs also in Durban Bay sediments dating from the mid-ÂHolocene or perhaps late Quaternary. New species: Nucula (Nucula) planiculmen, N. (N.) subluxa, N. (Lamellinucula) rhytidopleura; Ennucula oliva. Revised status: Nucula (Lamellinucula) sculpturata Sowerby, 1904, for N. pulchra auct. ( N. pulchra Hinds, 1843, is a nomen dubium). New synonym: Nucula fragilis Boshoff, 1968 = Nucula [= Ennucula] fragilis Thiele, 1931. Types figured: Lectotype (here designated) of Nucula fragilis Thiele, 1931, holotype of N. aequalitas Barnard, 1964. Type localities corrected: N. (L.) sculpturata, N. (L.) irregularis Sowerby, 1904 Development: Nucula planiculmen and N. subluxa are incubatory.
Designation of lectotypes for Microchaetus microchaetus (Rapp, 1849) and Microchaetus rappi Beddard, 1886, and historical perspectives on these species (Oligochaeta: Microchaetidae)Author Jadwiga Danuta PliskoSource: Annals of the Natal Museum 40, pp 269 –276 (1999)More Less
Microchaetus microchaetus (Rapp, 1849) is redescriptionbed, a lectotype designated and type depository indicated. M. rappi Beddard, 1886, is reassessed and determined to be a valid species, and its lectotype is designated. Historical perspective and synonymy for both species are provided. The gigantic species - M. braunsi Michaelsen, 1899, M. decipiens Michaelsen, 1899, M. klopperi Plisko, 1991, M. microchaetus (Rapp, 1849), M. rappi Beddard, 1886 and M. stuckenbergi Plisko, 1991, constitute a natural group within the genus Microchaetus, apparently confined to the Eastern Cape Province.
