Oosagitta gen. nov. from tropical Africa, with revision of two species and description of four new species (Coleoptera: Chrysomelidae, Galerucinae)
Full text linkAfter our taxonomic revision of Ootheca Chevrolat, 1837, and the description of Oothecoides Kortenhaus & Wagner, 2011 and Ootibia Kortenhaus & Wagner, 2012, it became clear that a further four galerucine species, closely related to the above named taxa, form a distinct monophyletic group, that constitutes a new genus, Oosagitta gen. nov. with O. anningae sp. nov., O. geescheae sp. nov., O. melanopicta sp. nov. and O. thomasi sp. nov.. Exosoma angolensis Laboissière, 1939, the type species of the new genus, and Ergana minuta Laboissière, 1937 are newly transferred to Oosagitta gen. nov. All species of Oosagitta gen. nov. are characterized by a broad body and pronotum, a more or less convex dorsum and short legs, and as such are most similar to the other above named genera. The antennae of Oosagitta gen. nov. are distinctly longer than those of Ootheca, Oothecoides and Ootibia. Genital structures of the males allow a reliable identifi cation of the genus. (Re-) descriptions are given for all species, including semi-schematic illustrations depicting the habitus outline, shape of the basal antennomeres and the median lobe. Photographs of the name-bearing types and distribution maps are provided
No Name, No Game
Full text linkIn an interesting contribution Joppa et al. (2011) revisit some aspects of the taxonomic impediment (Evenhuis 2007; http://www.cbd.int/gti/) and come to the conclusion that, contrary to the generally accepted idea, both the rates of species description and the number of taxonomists have increased exponentially since the 1950’s. Joppa et al. (2011) also note a marked decline in the number of species described per taxonomist which they attribute to the difficulty of finding new species in an ever declining ‘missing species pool’. Therefore, their results might be interpreted that today’s taxonomic workforce is sufficient to describe the remaining (shallow) ‘pool of missing species’. In this contribution, we question if this is indeed the case and propose a solution for speeding up taxonomic descriptions
On the mysterious Hylobius huguenini Reitter, 1891 (Coleoptera: Curculionidae: Molytinae)
No full textDuring verifications of museum material for the Catalogue of the Palaearctic Coleoptera, the type specimen of Hylobius huguenini Reitter, 1891 conserved in the Hungarian National Museum was examined. The type specimen had been found by Gustav Huguenin in the Emmental region in Switzerland. The species was never found again and remained therefore mysterious. After the examination of the type specimen, it became clear that Hylobius huguenini belongs to the American genus Heilipodus Kuschel, 1955 (comb. nov.), and there it ranks as a good species next to Heilipodus goeldii sp. nov., described here, and H. polyspilus (Pascoe, 1889), both from Brazil. The type specimens of Heilipodus goeldii sp. nov. were found in the Emil August Göldi-collection in the Natural History Museum of the Burgergemeinde Bern
Ichneumonid wasps from Madagascar. VI. The genus Pristomerus (Hymenoptera: Ichneumonidae: Cremastinae)
No full textPristomerus species of Madagascar are revised. We report 15 species, of which 12 are newly described: P. guinness sp. nov., P. hansoni sp. nov., P. kelikely sp. nov., P. keyka sp. nov., P. moramora sp. nov., P. melissa sp. nov., P. patator sp. nov., P. ranomafana sp. nov., P. roberti sp. nov., P. vahaza sp. nov., P. veloma sp. nov. and P. yago sp. nov. Pristomerus albescens (Morley) and P. cunctator Tosquinet are newly recorded from Madagascar and new host and/or distribution records are provided for this species. A dichotomous key to all species is provided. The zoogeographical relation of the Malagasy fauna of Pristomerus with respect to mainland Africa is discussed: only three of the 15 species are reported to occur outside of Madagascar, suggesting a high level of endemism in Madagascar which was not unexpected
Capalictus, a new subgenus of Lasioglossum Curtis, 1833 from South Africa, with description of three new species (Hymenoptera, Apoidea, Halictidae)
No full textCapalictus, a new subgenus of Lasioglossum Curtis, 1833 (Hymenoptera, Apoidea, Halictidae), endemic to the South African Cape Province, is described. The type species is Halictus mosselinus Cockerell, 1945. Evylaeus (Sellalictus) fynbosensis (Pauly et al., 2008) is a new junior synonym of L. (C.) mosselinum. Three new species are described: Lasioglossum (Capalictus) hantamense sp. nov., L. (C.) tigrinum sp. nov. and L. (C.) timmermanni sp. nov. DNA sequence data from three nuclear genes support morphologically-determined species limits. Capalictus is a basal clade of the Hemihalictus series of Lasioglossum
Second contribution to the knowledge of the Lithosiini of Gabon: the genus Nanna Birket-Smith (Lepidoptera, Erebidae, Arctiinae)
Full text linkThe presence of the genus Nanna in Gabon is treated. Four species are recorded, two of which are
new to science (N. molouba sp. nov. and N. semigrisea sp. nov.), and the hitherto unknown female of Nannaa ceratopygia is described. A checklist and a key to the species of the genus Nanna are provided
Review of Campsicnemus species from the Atlantic Ocean Islands (Diptera: Dolichopodidae)
Full text linkNew species Campsicnemus flavissimus sp. nov., C. meridionalis sp. nov., and C. sanctaehelenae sp. nov. are described from St. Helena. A review and key to seven Campsicnemus species inhabiting Azores, Canary Is., Madeira and St. Helena are provided. A new status (as subspecies of C. armatus Zetterstedt, 1849) for C. caffer Curran, 1926 stat. nov. is proposed
West Palaearctic species of the genus Diostracus Loew, 1861 (Diptera: Dolichopodidae)
No full textA new status (as subgenera of Diostracus Loew, 1861) for Sphyrotarsus Mik, 1874, Lagodechia Negrobov & Tsurikov, 1996 and Ozmena Özdikmen, 2010 stat. nov. is proposed. A new species, Diostracus (Sphyrotarsus) kustovi sp. nov., is described from the Russian Caucasus. The following recombinations (comb. nov.) are also proposed: Diostracus (Sphyrotarsus) argyrostomus (Mik, 1874); D. (S.) caucasicus (Negrobov, 1965); D. (S.) hervebazini (Parent, 1914); D. (S.) hessei (Parent, 1914); D. (S.) hygrophilus (Becker, 1891); D. (S.) leucostomus (Loew, 1861); D. (S.) parenti (Hesse, 1933); D. (Lagodechia) spinulifer Negrobov & Tsurikov, 1988; and D. (Ozmena) stackelbergi (Negrobov, 1965). A key to ten Diostracus species inhabiting the West Palaearctic Region is provided
Cyrioctea (Araneae, Zodariidae) in Africa: temperate Gondwanaland relict, recent radiation, or both?
No full textTwo new species of the zodariid genus Cyrioctea Simon, 1889 are described: C. sawadee sp. nov. and C. lotzi sp. nov., both only known from males. The genus now contains seven Afrotropical species and this abundance is discussed in the context of its basal situation in the family and its apparent temperate Gondwanaland distribution, which implies a much greater age of the Zodariidae than presently accepted. Unlike most taxa with a temperate Gondwana distribution, Cyrioctea boasts a high number of species with small distribution areas. This points in the direction of a recent radiation initiated after a long period of stasis
A new species of Hortipes (Araneae, Corinnidae), the first spider with an insertable retrolateral tibial apophysis on the male palp
Full text linkHortipes gigapophysalis (Araneae, Corinnidae) is a new species described from both sexes from montane forest on Mt Nimba, eastern Guinea. The species is remarkable for its long, whip-shaped retrolateral tibial apophysis (RTA) on the male palp. The structure apparently has an insertable function as the epigyne of the female contains a separate set of ducts starting from a central concavity that is unique in the genus. This duct system is apparently meant to receive the supple RTA. This type of structural arrangement has never previously been found in spiders
