The Family

Two species of large extension feeding barnacles are abundant on exposed tropical rocky shores of northern Australia. The cirri of many specimens carry varying numbers of a commensal diatom in some cases with as many as 2000 individuals on a single cirrus. The araphid diatom resembles the genus, Lichmophora within the family Fragilariaceae although no description has yet been published. Species of Lichmophora are common benthic diatoms in these waters as an epiphyte on macroalgae and common primary fouling diatoms on test panels. The diatom reported here has not been found on any substratum other than the barnacles Tetraclita squamosa and Australobalanus imperator, very rarely on Balanus amphitrite. Analysis of the diatom distribution on the cirri shows significantly higher numbers on the posterior captorial cirri. The effect of commensal diatoms on the feeding efficiency of the barnacles is discussed.

Following the revision of the family Pittosporaceae in Australia, a new genus, Auranticarpa, is described and monographed here to accommodate a monophyletic group excluded from Pittosporum in cladistic analyses. Auranticarpa occurs mostly in monsoonal northern Australia, and has six species. New combinations are provided for three taxa previously placed in Pittosporum: A. melanosperma, A. resinosa (reinstated this analysis) and A. rhombifolia; and three are described for the first time: A. edentata, A. ilicifolia and A. papyracea.

First Time

This paper reviews for the first time the family Pyramidellidae from northern Australia. The area includes the Solanderian zoogeographical province, and part of the Dampierian province. All species, whether previously described or now proposed as new, are figured and discussed. The division of the family into three new subfamilies is also proposed. In all 150 species or probable species belonging to 40 genera are reviewed. Of the genera 15 are proposed as new, and of the species 90 are proposed as new, and seven are left specifically unnamed pending the acquisition of more material. A key to the subfamilies and Australian genera is provided.

Based on specimens collected from eulittoral zone in rocky shores of northeast of Rio de Janeiro (Brazil) on 2017, two new tanaidaceans species from two different suborders are described: Apseudomorpha brasiliensissp. nov. (Apseudomorpha, Metapseudidae) and Pseudozeuxo fischerisp. nov. (Tanaidomorpha, Pseudozeuxidae). Diagnostic characters of Apseudomorpha brasiliensis are mandible palp article-2 and article-3 with six and nine finely penicillate setae on inner margin, respectively; pereopod-1 carpus and propodus with two and four ventral spines, respectively; pleonites 2 and 5 with pleura having long distal seta; uropod exopod shorter than endopod articles 1–2 combined, endopod four-articled. Pseudozeuxo fischeri is characterized by pereopods 1–3 coxa with long seta about half as long as basis; pereopods 2–3 carpus with ventrodistal seta; propodus with two ventral setae; pereopods 4–6 propodus with two ventral spines and one seta; uropod endopod two- and exopod one-articled. This is the first record of the family Pseudozeuxidae and the metapseudid subfamily Metapseudinae from the Southwestern Atlantic (Brazil). Remarks on their associations with macroalgae and identification keys to world species of Apseudomorpha and Pseudozeuxo are provided.

Pangandaran rocky shores have a unique ecosystem and a variant of invertebrate organisms such as mollusk from the gastropod class. This study aims to analyze the biodiversity of gastropods on the rocky shore of Karapyak beach. This research consists of 5 stations. The quadrant set by 1 m x 1 m vertically toward the sea. The result found 773 individuals scattered in nine families. The family of Neritidae dominated (43%), followed by family cyprinoids with 6.3%. Nerita plicata is a species found to dominate in every station with an average abundance (256 ± 10) and/m2. Using the Bray-Curtis cluster analysis, showed variations in the distribution and abundance of different gastropods vertically into the ocean and uniformly distributed horizontally to the shore. Substrate and tidal are the main variables in the spatial distribution of gastropods in the Karapyak beach.

This is the first book to deal exclusively with the Australian members of the Family Ardeidae (herons, egrets and bitterns). It gives a comprehensive, easy-to-read account of their origins, classification and biology, and explains the features that distinguish them from other birds. The book devotes a major chapter to the 14 Australian species, covering their distribution and movements, feeding, breeding, population dynamics and conservation. Some of Australia’s herons have become very scarce in the southern half of the continent and are at risk of national or local extinction. In northern Australia heron habitats and resources are largely pristine and consequently this region accommodates large numbers of certain species. A final chapter on population and conservation provides a useful summary of the present status of the Australian herons, some of whom are thriving and others who are in a very precarious position.

First Time

The family Macrophthalmidae Dana, 1851, is one of the best represented brachyuran groups in intertidal habitats in the Persian Gulf. Nine species from two subfamilies are reported from the gulf and the adjacent Gulf of Oman, mainly inhabiting intertidal soft substrates. The subfamily Ilyograpsinae Števcic, 2005, is represented by Ilyograpsus rhizophorae Barnard, 1950, erroneously recorded as I. paludicola (Rathbun, 1909). Eight species of the subfamily Macrophthalminae Dana, 1851, have been recorded from the area, all belonging to Macrophthalmus Desmarest, 1823. Of these, M. sinuspersici Naderloo & Türkay, 2010, has recently been described and is the only species of the genus occurring on rocky shores. Macrophthalmus graeffei A. Milne-Edwards, 1873, occurs in subtidal water and is hereby recorded for the first time from the northern Indian Ocean. The remaining six species, M. dentipes Lucas, 1836, M. depressus Rüppell, 1830, M. grandidieri A. Milne-Edwards, 1867, M. laevis A. Milne-Edwards, 1867, M. serenei Takeda & Komai, 1991, and M. sulcatus H. Milne-Edwards, 1852, are important elements of the intertidal soft bottom communities. An identification key for the genus Macrophthalmus in the area is provided, and the geographical distribution of the family is briefly discussed.

Dr. Guy A. K. Marshall has recently submitted to me a Trypaneid, discovered in Northern Australia by Mr. G. F. Hill. The fly is said to have been bred from larvae having habits very different from those of the related members of the family; and being moreover interesting from a morphological and biogeographical standpoint, it forms the object of the present note.

The Family

The genus Ailanthus Desfontaines (1788: 265) of the family Simaroubaceae comprises 5–10 species distributed in South and Southeast Asia as well as northern Australia (Nooteboom 1962, Peng & Thomas 2008). The species can be classified into two groups, i.e., one with toothed leaflets and the other with entire-margined leaflets. The latter group currently includes five species, A. triphysa (Dennstedt 1818: 32) Alston (1931: 41), A. vietnamensis H.V.Sam & Nooteboom (2007: 555), A. fordii Nooteboom (1962: 220), A. integrifolia Lamarck (1792: 417), and A. guangxiensis S.L.Mo ex C.F.Liang & S.L.Mo (1982: 145). The last species was described based on two fruit collections from Longzhou County, Guangxi Province, China. In the protologue, the authors stated that it was clearly distinguished from its congeneric species by the large samaras. After that, A. guangxiensis is always considered as an endemic species of Guangxi (Peng & Thomas 2008, Qin & Liu 2010, Mo 2011). In 2010, it was listed as a key protected wild plant of Guangxi by the local government.
