Abstract

A new species of the genus Paralomis (Crustacea: Decapoda: Lithodidae) from the Spiess seamount near Bouvet Island (Southern Ocean), with notes on habitat and ecology Abstract A new species of the genus Paralomis, Paralomis elongata, has been collected from the Spiess seamount near Bouvet Island in the Southern Ocean. The species shows close affinity with P. anamerae Macpherson, 1988, from the Patagonian Shelf, P. africana Macpherson, 1987, from the south-western African shelf, and P. aculeata Henderson, 1888, from Crozet Islands. Morphological differences among the species and ecological characteristics are discussed.

Energetic changes throughout lecithotrophic larval development in the deep-sea lithodid crab Paralomis spinosissima from the Southern Ocean

“…Research into this decapod family in recent years has been driven by a steep increase in the discovery rate of new species (Macpherson, 2004;Spiridonov et al, 2006;Hall and Thatje, 2009a,b), the potential for opening new fisheries (López-Abellán and Balguerías, 1994; Watters, 1997;Collins et al, 2002;Purves et al, 2003), as well as biogeographic range shifts, either as introduced species and/or in response to climate warming (Orlov and Ivanov, 1978;Jorgensen et al, 2005;Thatje et al, 2005a;Aronson et al, 2007).…”

Temperature-driven biogeography of the deep-sea family Lithodidae (Crustacea: Decapoda: Anomura) in the Southern Ocean

“…(1) Published records of lithodids were sourced from peerreviewed journals and other literature (including some comprehensive reviews of faunal distributions in diVerent regions of the Southern Ocean Acosta et al 1989;Ahyong and Dawson 2006;Ahyong 2010;Arana and Retamal 1999;García Raso et al 2005;Klages et al 1995;López Abellán and Balguerías 1993;Macpherson 1988Macpherson , 2004Miquel et al 1985;Purves et al 2003;Spiridonov et al 2006;Thatje et al 2005Thatje et al , 2008 Identity was veriWed from descriptions and pictures, or by inspection where samples were deposited in museums. For each specimen studied, the depth, location and date of sample collection were noted.…”

Missing link in the Southern Ocean: sampling the marine benthic fauna of remote Bouvet Island

“…sp. ; Spiridonov et al 2005). Furthermore, five deep-sea carideans (Nematocarcinus lanceopes) were collected, at their most shallow depths known to date (Gorny 1999).…”

“…Paralomis elongata sp. n. (Spiridonov et al 2005) is the only anomuran crab found at the Spiess Seamount. Its presence not only in a few trawls, but also on the underwater images, indicates this stone crab to be an important faunistic element of the seamount benthos (Fig.…”
