A taxonomic survey of marine and estuarine benthic green algae has been conducted at Lord Howe Island, the site of the world’s southernmost (at 31.5˚S) consolidated coral reef. Thirty-two genera and 71 species are described from habitats ranging from upper intertidal to 20–30-m depths. Sixteen of the species are based on Lord Howe types, and 11 are described as new. Twelve species are currently known only from the Island. Particularly well represented in the flora are the genera Enteromorpha (six species, one variety), Chaetomorpha (four species), Cladophora (13 species),Codium (five species), Caulerpa (seven species, two varieties) and Bryopsis (three species). The island is further distinctive in having two representatives of some relatively obscure genera (Cladophoropsis, Rhipiliopsis, Pseudochlorodesmis) and in being the highest-latitude collecting locality for several species. Affinities of the Lord Howe flora are primarily tropical Indo-Pacific, with very few elements otherwise restricted to southern Australia and New Zealand.

The marine benthic green macroalgae of the New South Wales mainland and of Lord Howe Island are listed, each with bibliographic, distributional and specimen-voucher details. Included are 113 species in 9 orders, 14 families and 38 genera, of which 12 species are based on New South Wales types. With respect to biodiversity, New South Wales is as rich in numbers of genera and species as southern Australia. Eight genera (Pedobesia, Boodlea, Neomeris, Trichosolen, Ventvicaria, Caulerpella, Pseudochlorodesmis, Sporocladopsis) and 41 species are new records for the State, and 14 species are newly recorded for the Australian continent. The largest genus represented is Cladophora; 22 species are recorded, 13 from Lord Howe Island alone, and 7 are new to Australia (C. cymopoliae, C. colabense, C. dotyana, C. nigrescens, C. ohkuboana, C. patentirainea, C. ryukyuensis). Examination of type and recently collected material of Caulerpa annulata (from Port Arthur, Tasmania) shows it to be synonymous with the earlier Caulerpa hodgkinsoniae (from Ballina, New South Wales).

New Diagnosis

Four new species of Actaecia Dana are described from Australia; three of these (A. bipleura, A. cyphotelson and A. nasuta) are from beaches in south-eastem Australia and one (A. forrnida) is from the mid-eastern coast of Queensland. Specimens from Tasmania identified previously as Actaecia pallida Nicholls & Barnes belong to A. bipleura. The same probably applies to others from New South Wales and Lord Howe Island. The distributions of the six Australian species are noted. A review of the monogeneric family Actaeciidae includes a new diagnosis of Actaecia and a key to species. The distributions of the two New Zealand species are listed.

AbstractThe lithobiomorph centipede Henicops is widely distributed in Australia and New Zealand, with five described species, as well as two species in New Caledonia and Lord Howe Island. Parsimony, maximum likelihood and Bayesian analyses of ca. 800 aligned bases of sequence data from 16S rRNA and 28S rRNA were conducted on a dataset including multiple individuals of Henicops species from populations sampled from different parts of species' geographic ranges, together with the allied henicopines Lamyctes and Easonobius. Morphological characters are included in parsimony analyses. Molecular and combined datasets unite species from eastern Australia and New Zealand to the exclusion of species from Western Australia, New Caledonia and Lord Howe Island. The molecular data favour these two geographic groupings as clades, whereas inclusion of morphology resolves New Caledonia, Lord Howe Island, southwest Western Australia and Queensland as successive sisters to southeastern Australia and New Zealand. The basal position of the Lord Howe Island species in the phylogeny favours a diversification of Australasian Henicops since the late Miocene unless the Lord Howe species originated in a biota that pre-dates the island. The molecular and combined data resolve the widespread morphospecies H. maculatus as paraphyletic, with its populations contributing to the geographic groupings New South Wales + New Zealand and Tasmania + Victoria.

Galaxias maculatus is a small diadromous fish found in Australia, New Zealand, South America and on some oceanic islands. Two hypotheses have been advanced to explain this widespread, disjunct distribution. McDowall promoted dispersal through the sea of salt-tolerant juveniles but Rosen and others claimed that the distribution reflected the break-up of Gondwana and subsequent drift of the southern continents. Allozyrne electrophoresis of muscle extracts of specimens of Galaxias maculatus from eastern and western Australia, New Zealand and Chile was used to test the hypothesis that populations of G. maculatus from the western Pacific and the eastern Pacific do not differ genetically. FST based on allele frequencies and genotypes was 0.14, suggesting only minor differentiation between eastern and western Pacific populations. Minor differentiation in allele frequency existed at some loci, but no fixation of alternative alleles has occurred. The populations examined appear to be part of the same gene pool, indicating that gene flow via dispersal through the sea occurs today. It is unlikely that South American and Australasian populations would be conspecific if they have exchanged no migrants since the break-up of Gondwana at the end of the Mesozoic.

A new species of tube-dwelling diatom, unusual in being araphid, is described from benthic coral reef habitats in Guam, Palau, Puerto Rico and Jamaica. Gato gen. nov. is heteropolar and heterovalvar, exhibits very fine striae delimiting a narrow and irregular sternum, and possesses a series of rimmed pores on each side of the foot pole. One valve of the frustule has a rimoportula at the foot pole, but both valves possess a rimoportula at the head pole. The generitype, G. hyalinus sp. nov. forms small, branched colonies. Individual cells are oval, slightly tapered along the apical axis, 30–40 µm x 13–15 µm, with 60–70 striae in 10 µm. On the foot pole with a rimoportula the rimmed pores are connected to the sternum by diagonal striae; several additional rimmed pores interrupt transapical striae further up both valves. We compare valve structure of G. hyalinus with Florella portoricensis and F. pascuensis, which we report for the first time from the Marshall Islands, and to Licmophora spp. We find no taxa to which this genus is related, and can identify no structure potentially homologous to the series of rimmed pores among the diatoms.
