(Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: the Genera Nodilittorina, Austrolittorina and Afrolittorina
© Copyright Australian Museum, 2004 Records of the Australian Museum (2004) Vol. 56: 75–122. ISSN 0067-1975 The Subfamily Littorininae (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: The Genera Nodilittorina, Austrolittorina and Afrolittorina DAVID G. REID* AND SUZANNE T. WILLIAMS Department of Zoology, The Natural History Museum, London SW7 5BD, United Kingdom [email protected] · [email protected] ABSTRACT. The littorinine gastropods of the temperate southern continents were formerly classified together with tropical species in the large genus Nodilittorina. Recently, molecular data have shown that they belong in three distinct genera, Austrolittorina, Afrolittorina and Nodilittorina, whereas the tropical species are members of a fourth genus, Echinolittorina. Austrolittorina contains 5 species: A. unifasciata in Australia, A. antipodum and A. cincta in New Zealand, and A. fernandezensis and A. araucana in western South America. Afrolittorina contains 4 species: A. africana and A. knysnaensis in southern Africa, and A. praetermissa and A. acutispira in Australia. Nodilittorina is monotypic, containing only the Australian N. pyramidalis. This paper presents the first detailed morphological descriptions of the African and Australasian species of these three southern genera (the eastern Pacific species have been described elsewhere). The species-level taxonomy of several of these has been confused in the past; Afrolittorina africana and A. knysnaensis are here distinguished as separate taxa; Austrolittorina antipodum is a distinct species and not a subspecies of A. unifasciata; Nodilittorina pyramidalis is separated from the tropical Echinolittorina trochoides with similar shell characters. In addition to descriptions of shells, radulae and reproductive anatomy, distribution maps are given, and the ecological literature reviewed. -

Keywords Orthalicoidea, taxonomy, Bostrycinae subfam. n. Introduction Troschel (1847: 49) described a new, peculiar land snail, as Bulimus (Bostryx) solu- tus. He wrote: “Diese durch Herrn Dr. von Tschudi in Peru in vielen Exemplaren gesammelte Art ist so eigenthümlich, dass ich überzeugt bin, sie werde bei einer na- turgemässen Theilung der Gattung Bulimus, wovon die Notwendigkeit nach meinem anatomischen Untersuchungen keinen Zweifel unterliegt, eine eigene Gattung bilden, für die ich den Namen Bostryx vorschlage”. However, Troschel’s conviction that Bostryx constituted a separate genus was not readily accepted. -

China Abstract.- The effect of saltmarsh cordgrass, Spartina alterniflora (Poales: Poaceae) invasion stage on Cerithidea cingulata (Caenogastropoda: Potamididae) distribution was studied in 2007 at the eastern tidal flat of Lingkun Island, Wenzhou Bay, China. The distribution pattern of C. cingulata was aggregated during each season, as shown in experiments utilizing Taylor's power regression and Iowa's patchiness regression methods (P < 0.001). Two- way ANOVA indicated that densities were significantly affected by S. alterniflora invasion stage (P < 0.001), however, no significant season effect was found (P = 0.090) and on the interaction between the seasons (P = 0.939). The density distribution during the invasion stage was significantly different in each season as shown in one-way ANOVA. Pearson’s correlation coefficient analysis of density data indicated that the highest densities occurred in habitats at the initial invasion stage during summer. The peak in C. cingulata density during spring, autumn and winter occurred in habitats where invasion was classified as initial, whereas the lowest densities occurred in the stage of invasion completed during each season. -

Jurusan Manajeman Sumberdaya Perairan, Fakultas Ilmu Kelautan dan Perikanan, Universitas Maritim Raja Ali Haji. Pembimbing oleh Diana Azizah S.Pi., M.Si dan Susiana S.Pi., M.Si. Tujuan dari penelitian ini adalah untuk mengetahui tingkat pemanfaatan siput hisap (Cerithidea obtusa) di perairan muara Sei Jang kelurahan Sei Jang kota Tanjungpinang. Penelitian ini dilakukan pada bulan Januari sampai bulan juli 2017. Pengambilan sampel siput hisap dengan menggunakan transek 2 x 2 m. Data Ekosistem mangrove di Sei Jang menggunakan data sekunder (dari penelitian sebelumnya). Mangrove yang ditemukan di Kelurahan Sei Jang merupakan vegetasi mangrove alami, dimana dibedakan atas 3 bagian yaitu Pohon, Anakan dan Semai. Potensi siput hisap (Cerithidea obtusa) pada lokasi penelitian di hutan mangrove Sei Jang Kelurahan Sei Jang dari nilai potensi yang di dapat adalah 10,5390 kg, nilai ini menunjukan bahwa potensi yang rendah. Rendahnya nilai kepadatan dan potensi siput hisap (Cerithidea obtusa) di hutan mangrove muara Sei Jang dari hasil penelitian diduga karena kandungan bahan organik substrat pada setiap titik stasiun penelitian masih rendah.
