Exogoninae (Polychaeta: Syllidae) from Australia with the description of a new genus and twenty-two new species

Abstract

Large collections of Syllidae (Polychaeta) from around Australia, which were deposited at the Australian Museum (Sydney), and at Museum Victoria as well as some specimens from Tasmania, have been examined and identified. Additionally material from the Hamburgische Zoologische Museum der Universität, Hamburg, Germany was examined. All known Australian species of the subfamily Exogoninae (Syllidae) are described and figured. Some were examined using the Scanning Electron Microscope to illustrate some characters and methods of reproduction in this subfamily. Keys to genera and species are given. A total of 74 species are reported from Australia belonging to 8 genera: Nooralia

First Records of Polychaetous Annelids from Cenote Aerolito (Sinkhole and Anchialine Cave) in Cozumel Island

“…Although some species of Exogoninae of the Caribbean have been reported by Ruíz-Ramírez and Salazar-Vallejo (2000), the species Erinaceusyllis centroamericana is a new record for the Mexican Caribbean. This species had been previously recorded from the West Indies (San Martín, 2005). Syllis prolifera is considered cosmopolitan but, like Syllis maryae, the closest records to the study area are from Cuba and the Gulf of Mexico (San Martín 1992;.…”

“…Circumtropical: El Salvador, Galá pagos Islands, Caribbean Sea, Hawaii, Samoa, Angola, Mozambique, Tanzania, Australia (San Martín, 2005). New record for Mexican Caribbean.…”

Guía y claves para el reconocimiento de las subfamilias, géneros y especies de Syllidae registradas a lo largo de la costa de Chile, archipiélago Juan Fernández e isla de Pascua (Annelida: Phyllodocida: Syllidae)

“…Esta sección sobre generalidades, morfología y reproducción de la familia Syllidae está basada principalmente en San Martín (2003), Aguado et al (2012), San Martín & Aguado (2014) y San Martín & Worsfold (2015.…”

“…La incubación de los huevos puede ser dorsal, mediante notosedas capilares, o ventral, sujetos al nefridióporo. En este último caso, los juveniles crecen sujetos al cuerpo de la madre, pero en la incubación dorsal se forman larvas (San Martín, 2005).…”

Description of a new species of Sphaerosyllis Claparède, 1863 (Polychaeta: Syllidae: Exogoninae) from the Alicante coast (W Mediterranean) and first reports of two other species of Syllidae for the Mediterranean Sea and the Iberian Peninsula

“…This family has more than 70 genera and around 700 valid species worldwide (Aguado & San Martín, 2009;Aguado et al, 2012). Moreover, in recent years, this number has rapidly increased with the discovery of new genera and species (San Martín, 2002, 2005San Martín & López, 2003;San Martín & Hutchings, 2006;San Martín et al, 2007;Aguado & San Martín, 2008;Ding & Westheide, 2008, among many others). Their importance is reflected in a large number of studies dedicated to them (Somaschini & Gravina, 1994;Nygren, 1999;Glasby, 2000;Çinar & Ergen, 2002;Çinar, 2003, among many others).…”
