A revision of the Australian taxa of the genus Spergularia (Caryophyllaceae) on the basis of herbarium material, field studies and analysis of morphological characters necessitates realignment of some taxa and application of some neglected names, clarifying circumscription and understanding of the species of this genus. Eleven species are here recognised, with five considered indigenous, Spergularia nesophila and S. diandroides described as new and S. tasmanica transferred to Spergularia from Lepigonum. Fruits and seeds provide compelling diagnostic characters in this genus and are used in supplementary dichotomous and tabular diagnostic keys. Scanning electron micrographs (SEMs) illustrate key seed shape and surface features.

A taxonomic revision of the flea beetle genus <em>Diphaulacosoma</em> Jacoby, endemic to Madagascar, is provided. This genus includes seven species of which three are new to science: <em>D. elegans</em> sp. n., <em>D. jenisi</em> sp. n., and <em>D. nigroscutis</em> sp. n. An updated catalogue including new material, new faunistic records, distributions, chorotypes, and ecological notes is supplied. Lectotypes for <em>Diphaulacosoma</em> <em>laevipenne</em> Jacoby, <em>D. bicolor</em> (Weise) and <em>D. scutellare</em> (Weise) are designated. Additionally, the revision comprises a key for the identification of all seven species considered, habitus photos, and microscope and scanning electron micrographs of diagnostic characters, including aedeagus and spermatheca.

There is a geographic separation of the two pollen morphs in European Silene latifolia, with the changeover zone running northwest – southeast from the Netherlands to Greece. Reticulate grains are characteristic of western populations and microechinate grains are characteristic of eastern populations. The present study is based on a sample of one pollen grain from each of the male individuals from each of 32 greenhouse-grown populations representing the distribution of S. latifolia across Europe. The 316 grains were scored for 11 morphological characters (61 character states) under the light microscope. Population character-state frequencies were analysed using cluster analysis and principal components analysis. The results support the geographic distribution of pollen morphs, but the populations with the typical eastern and western morphs are linked by a belt of populations with intermediate pollen morphology. Intermediate pollen is characteristic of populations in a zone from Belgium to Italy; the zone represents a region of relatively rapid morphological change and is coincident with a similar zone of change in seed and flavonoid characters in S. latifolia. Scanning electron micrographs from each population provided further information on the pollen morphology and complemented the light microscopical observations. The variation pattern is illustrated by scanning electron micrographs from selected populations.

In this paper a revision of the Afrotropical flea beetle genus Serraphula Jacoby, 1897 is reported. Three species previously attributed to this genus are transferred to the new genus Bechynella gen. n. and the following new combinations are established: Bechynella bohumilae (Bechyné, 1955) comb. n.; Bechynella pallens (Bechyné, 1955) comb. n.; Bechynella sesengensis (Bechyné, 1959) comb. n. The genus Serraphula includes currently 19 species, 16 of which are new to sci-ence: Serraphula aenea Jacoby, 1897; S. elongata Jacoby, 1900; S. puncticollis Bryant, 1944; S. alticola sp. n.; S. audisiana sp. n.; S. bulirschi sp. n.; S. colonnellii sp. n.; S. debiasei sp. n.; S. drakensbergensis sp. n.; S. duplessisi sp. n.; S. grobbelaariae sp. n.; S. monticola sp. n.; S. mpumalangaensis sp. n.; S. natalensis sp. n.; S. oberprieleri sp. n.; S. osellai sp. n.; S. transvaalensis sp. n.; S. uysi sp. n.; S. wittmeri sp. n. Lectotypes for S. aenea, S. elongata and S. puncticollis are designated. A key to all the species is presented as well as line drawings of male and female genitalia, scanning electron micrographs of some diagnostic morphological characters, and autoecological and distributional data.

The previously monotypic genus Tritonus Mulsant is revised. Six new species are described from Madagascar, from which the genus is also recorded for the first time: T. complanatus sp.n., T. crenulatus sp.n., T. madagascarensis sp.n., T. riambavy sp.n., T. riana, sp.n., and T. steineri sp.n. New records for the previously described and Mauritian-endemic species Tritonus cribratus (Mulsant) are given. All known species occur in hygropetric habitats, consistent with the biology of other members of the Oocyclus-genus group of the tribe Laccobiini to which Tritonus belongs. A key to species, aedeagal illustrations, and scanning electron micrographs of diagnostic characters are provided.

A detailed morphological examination of 12 specimens representing seven species in the genera Lamproderma and Meriderma collected from snowbank habitats in the Himalayan Mountains in northwestern India was carried out. Two of the specimens are described herein as Lamproderma spinisporum, a species new to science. In addition, the material from northwestern India is compared with other similar taxa belonging to the genus Lamproderma. Light microscope photographs and scanning electron micrographs of the most representative morphological characters are provided.

The North American species of the broad-nosed weevil genus Pachyrhinus Schönherr 1823 (Coleoptera: Curculionidae, Entiminae) are revised. Three species of Pachyrhinus are here recognized in North America: P. elegans (Couper 1865), P. californicus (Horn 1876), and P. cinereus (Casey 1888). Pachyrhinus lateralis (Casey 1888) and P. miscix (Fall 1901) are here designated as synonyms of P. elegans. Pachyrhinus crassicornis (Casey 1888) and P. albidus (Fall 1901) are here designated synonyms of P. cinereus (Casey 1888) The previously proposed synonymy of P. ferrugineus (Casey 1888) with P. californicus was confirmed. This revision includes detailed images of diagnostic characters as well as scanning electron micrographs of scale morphology for all species. A key to the Nearctic species of Pachyrhinus is provided. All Nearctic species of Pachyrhinus are considered minor pests of Pinus spp. [Pinaceae].

The family Sabellariidae is represented in Australian waters by eleven species belonging to five genera, including eight of themnew to Science: Idanthyrsus nesos n. sp., I. willora n. sp., Lygdamis wambiri n. sp., Phalacrostemma maloga n. sp., Sabellariakooraltha n. sp., S. lungalla n. sp., S. pyramis n. sp., and Tetreres terribilis n. sp. Three genera, Phalocrostemma, Sabellaria andTetreres, are newly recorded from Australia. Descriptions of all species are given, acompanied by detailed illustrations, includingdrawings, photographs and scanning electron micrographs, tables summarising specific diagnostic characters of all species ofeach genus, and distribution maps within Australia. A key to all genera worldwide and Australian species is given. Maximumparsimony analyses based on morphological features have been performed to assess the position of the new species and relation-ships with other Sabellariidae. For this purpose, the Australian species, the type species of each genus and some others species,representing the variability within each group, were incorporated into the analyses. Some of the species were recovered withinmonophyletic genera (Phalacrostemma and Tetreres), while others have been considered as member of previously recognised genera (Idanthyrsus, Lygdamis and Sabellaria) have not been assessed as monophyletic.

Zanna robusticephalica sp. nov. (Hemiptera: Fulgoromorpha: Fulgoridae: Zanninae: Zannini), representing the third species of the planthopper genus Zanna Kirkaldy, 1902 from China, is described and illustrated from Yunnan in southwestern China. Scanning electron micrographs of the antennal sensilla, rostral apex, hind tarsal segments, gonoplac and wax glands of the new species are provided. The generic diagnostic characters of Zanna are redefined and the autapomorphies are proposed to support the monophyly of the genus. A check-list of the Oriental Zanna species is included.
