Three new species of Aponuphis (Annelida: Onuphidae) from eastern Australia

Zootaxa (2017)

Hannelore Paxton

The genus Aponuphis, previously known from the eastern North Atlantic and the Mediterranean, is newly reported from Australia. Three new species are described from off Sydney to Wollongong, New South Wales in sandy sediments, in depths of 25-70 m, bringing the number of recognized Aponuphis species to ten. Aponuphis annae n. sp. and A. bellani n. sp. are abranchiate, whilst A. danicae n. sp. has branchiae over a short region of its body. The tubes of A. annae and A. danicae have a fragile mucous consistency with attached sand grains and that of A. bellani is transparent, tight-fitting and smooth. Two specimens of A. annae were collected with developing juveniles in their tubes demonstrating their direct development but the reproductive mode of the other two species is not known. The distinguishing characteristics of all recognized species are tabled and a key to the three Australian species is presented.

Biogeography and incipient speciation inOphryotrocha labronica(Polychaeta, Dorvilleidae)

Marine Biology Research (2005)

Bertil Åkesson Hannelore Paxton

Crossing experiments were conducted between the Naples I (NI) strain of Ophryotrocha labronica labronica, three strains of O. l. pacifica from Japan (M3), Hawaii (WH) and Los Angeles (LA), two strains of O. labronica from Australia and one from an unknown origin, discovered in a Moscow aquarium, to determine the relationships between the European and Pacific subspecies, and the newly discovered strains. Previously published data combined with new results revealed several stages in the process of speciation within the sibling group. Interpopulation crosses yielded an increased sex ratio that appears to be positively related to genetic distance and to the sex ratio of the parent strains. Fecundity data demonstrated that the three northern Pacific strains are more closely related to each other than to any other strain, confirming that they are a valid subspecies, and indicate that they are the result of natural distribution. The strain of unknown origin as well as the Australian strains clearly belong to O. l. labronica. Its isolated presence in the South Pacific may be a remnant of an earlier wider distribution or an introduction of the Mediterranean population, as the life histories of Ophryotrocha species have made them prime candidates for anthropogenic dispersals.

The lower bathyal and abyssal seafloor fauna of eastern Australia

Marine Biodiversity Records (2020)

Timothy D. O’Hara Alan Williams S. T. Ahyong Philip Alderslade Tom Alvestad

Abstract Background Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over the last 150 years. In May–June 2017, the IN2017_V03 expedition of the RV Investigator sampled LBA benthic communities along the lower slope and abyss of Australia’s eastern margin from off mid-Tasmania (42°S) to the Coral Sea (23°S), with particular emphasis on describing and analysing patterns of biodiversity that occur within a newly declared network of offshore marine parks. Methods The study design was to deploy a 4 m (metal) beam trawl and Brenke sled to collect samples on soft sediment substrata at the target seafloor depths of 2500 and 4000 m at every 1.5 degrees of latitude along the western boundary of the Tasman Sea from 42° to 23°S, traversing seven Australian Marine Parks. Results The biological sampling included 35 beam trawls, 28 Brenke sleds, 8 box cores, 20 surface meso-zooplankton tows, and 7 Deep Towed Camera transects. In total, 25,710 specimens were identified to 1084 taxonomic entities, including 847 species-level, 144 genus-level and 69 family-level and 24 higher-level taxa. Of the species-level taxa, only 457 were assigned species-level taxonomic names, which implies that up to 58% of the collected fauna is undescribed. In addition, the ranges of numerous species have been extended to include the western Tasman Sea. Conclusions The lower bathyal and abyssal fauna of soft sediment seafloors off eastern Australia has been systematically surveyed for the first time. The resultant collections will provide the foundation for much future ecological, biogeographical, phylogenetic and taxonomic research.

Mooreonuphis vespa, a new brooding species of Onuphidae (Annelida) from northern Spain (Bay of Biscay)

Zootaxa (2013)

Andrés Arias Hannelore Paxton Nuria Anadón

A new species of the genus Mooreonuphis Fauchald, 1982 collected from the Cantabrian shelf (Bay of Biscay) is described. Mooreonuphis vespa sp. nov. constitutes the first record of this genus in European waters and is characterised by: conspicuous dark brown transverse segmental pigment bands; antennae and palps with 3–5 basal ceratophoral rings and a very long distal ring; unusually long and slender peristomial and dorsal cirri; simple branchiae from chaetiger 17–19. We present observations on its reproductive biology (including brooding behaviour) and remark on the biogeography of the genus.

Hirsutonuphis (Polychaeta : Onuphidae) from Australia, with a discussion of setal progression in juveniles

Invertebrate Systematics (1996)

Hannelore Paxton

This study recognises five Australian species of Hirsutonuphis, of which three are newly described; a key to adults is provided. Juvenile stages of the three new species, ranging from recently settled to near adult individuals, are described, with emphasis on the appearance and replacement of provisional and permanent hooks. Anterior pseudocompound hooks are generally preceded by compound falcigers. Two types of anterior provisional subacicular hooks, representing relict structures, occur in juveniles. Posterior provisional hooks, representing precursor subacicular hooks, occur in juveniles and the most posterior segments of adults. This study demonstrates that while setal progression in the genus shows species specific differences, it follows a pattern that is similar for allied genera but not identical for the whole family.

Hyalinecia (sic) Edwardsi Roule, 1898—the enigmatic ghost from abyssal depths—redescribed as Nothria edwardsi (Annelida: Onuphidae)

Zootaxa (2016)

Andrés Arias Hannelore Paxton

The deep sea is one of the largest ecosystems on earth, extending from 200 m, where sunlight becomes inadequate for photosynthesis, to the deepest trenches. However, it is still one of the least explored. Polychaetes are among the dominant groups in these environments worldwide and play a critical role in the deep sea food chain. Within polychaetes, the onuphids are one the best represented families from 2000 m deep to the hadal zone, with 46 recorded species (Paterson et al. 2009). Hyalinoecia edwardsi Roule, 1898 is one of the early described abyssal onuphids. The species was described from the Talisman station 136, located between the Azores archipelago and the Iberian Peninsula (referred as "l'Espagne") at 4255 m depth (Roule 1898). The original description is rather brief without illustrations and the species was characterised as follows: thick antennae, lateral ones reaching chaetiger 3; first chaetiger twice as long as second one; parapodia of first chaetiger with thick falcate hooks; parapodia of second chaetiger with bidentate hooks; parapodia of third chaetiger with limbate chaetae; following chaetigers with limbate, pectinate chaetae and subacicular hooks; oval tube looking flattened and covered by small particles, mainly quartzites of different colours (Roule 1898).

A New Species of Palpiphitime (Annelida: Dorvilleidae) from Western Canada

Proceedings of the Biological Society of Washington (2009)

Hannelore Paxton

Palpiphitime lipovskyae, new species, is described on the basis of specimens collected near an Atlantic salmon farm in Hecate Strait, British Columbia, Canada. The new species differs from P. lobifera (Oug, 1978), the only other described species in the genus, by having lamella-like dorsal and digitate ventral lateral lobes, its parapodia lacking ventral chaetal lobes, mandibles with fewer teeth, and P-forceps having serrated ridges with alternating large and small teeth. The definition of Palpiphitime Orensanz, 1990 is expanded to include the characteristic jaws.
