Terebellidae (Annelida, Terebelliformia) from Lizard Island, Great Barrier Reef, Australia

Abstract

In a survey of the polychaetes of the Lizard Island region, sixteen new species of terebellids, plus one previously described species, were found from material collected during the two week long Lizard Island Taxonomic Workshop in 2013, along with material collected from previous projects carried out at Lizard Island. This included the CReefs Project (http://www.aims.gov.au/creefs/field-program.html), of which Lizard was one of the nodes. Those species are distributed as follows: one species of each of the following genera Eupolymnia Verrill, 1900, Lanice Malmgren, 1866; Lanicides Hessle, 1917, Lanicola Hartmann-Schröder, 1986, Pistella Hartmann-Schröder, 1996, Reteterebella Hartman, 1963, and Terebella Linnaeus, 1767; two species of Nicolea Malmgren, 1866; three species of Pista Malmgren, 1866 and four of Loimia Malmgren, 1866, together with another new species, belonging to the new genus Lizardia n. gen. Keys for identification of these genera and species are provided, together with generic diagnoses and full descriptions for all species; for each new species, comparisons with the morphologically most similar congeners are provided. A redescription of Reteterebella queenslandia Hartman, 1963 is also included.

Telothelepodidae, Thelepodidae and Trichobranchidae (Annelida, Terebelliformia) from Lizard Island, Great Barrier Reef, Australia

“…in having a longer prostomial process; a longer and highly convoluted upper lip and shorter deeply corrugated lower lip; in both species segment 1 is forming complete annulation around the body and segment 2 is not continuing ventrally, and both species have many more branchial filaments, ~20-30 filaments on each side of pairs (Nogueira et al 2010). In contrast, in Rhinothelepus oculeus n. sp.…”

“…In Pseudostreblosoma Hutchings & Murray, 1984, lobes may be present on anterior segments, notopodia begin from segment 2 and they bear winged and serrated notochaetae, the latter only present on posterior segments with notopodia (Hutchings & Glasby 1987;Nogueira & Alves 2006). In Pseudothelepus binara Hutchings, 1997b, the only species in this genus, lobes are present on segments 6-7, notopodia begin from segment 3 and neuropodia from segment 6 (Hutchings 1997b, Nogueira et al 2010, while in both Streblosoma Sars, 1872 and Thelepus Leuckart, 1849, lobes on anterior segments Type-species. Grymaea bairdi Malmgren, 1866, by original designation.…”

“…Trichobranchus is characterized by the presence of peristomial lobes originating laterally to the lower lip and terminating dorso-laterally, and by a large, eversible mid-ventral process on segment 1, which, when retracted, is folded between segments 1 and 2. As discussed by Nogueira et al (2010Nogueira et al ( , 2013, species of this genus were considered as belonging to Artacamella Hartman, 1955 when the process of segment 1 is everted, and to Trichobranchus when it is retracted, until Garraffoni & Lana (2004) synonymised Artacamella with Trichobranchus. The genus is currently includes eight species (Hutchings & Peart 2000), two of which described from Australia, T. bunnabus Peart, 2000 andT.…”

Peer Review #2 of "Review of the genus Loimia Malmgren, 1866 (Annelida, Terebellidae) from China seas with recognition of two new species based on integrative taxonomy (v0.2)"

“…Loimia species are normally found in tropical areas, with only a few species inhabiting subtropical areas, and no species inhabiting Arctic areas (Lavesque et al, 2017). The genus Loimia can be distinguished by the presence of pectinate uncini, a feature unique to Terebellidae (Nogueira, Hutchings & Carrerette, 2015). Other characteristics useful in the identification of species within this genus are: (1) the shape and position of the lobes on segments 1 and 3; (2) the number, arrangement, and shape of the mid-ventral glandular shields;…”

“…The genus Loimia Malmgren, 1865 comprises 29 valid species occurring worldwide, and most of them are found in tropical areas (Lavesque et al, 2017). Live specimens of Loimia, living in tubes, are usually large and brightly colorful, with long, grooved tentacles and blood-red regions at the termination of mid-ventral shields (Nogueira, Hutchings & Carrerette, 2015).…”
