New species of the genus Zeuxo (Peracarida, Tanaidacea)

  title={New species of the genus Zeuxo (Peracarida, Tanaidacea)},
  author={K. Larsen},
Two new species of Zeuxo Templeton, 1840 are described, one from Korea (Z. koreaensis), belonging to the Z. normani (Richardson, 1905) species complex, and one from Turkey (Z. turkensis). Two other Zeuxo species (Z. exsargasso Sieg, 1980 and Z. holdichi Bamber, 1990) are redescribed. The species Z. paranormani Sieg, 1980 is demoted to a junior synonym of Z. normani, while the ‘Zeuxo normani’ from Australia is raised to full species rank under the name Z. edgari. 
Two new species of the genus Zeuxo (Peracarida: Tanaidacea) from the west and south coast of Korea
Detailed morphological features between same- and different-sized females of Zeuxo gracilis are compared and discussed, and additional character states are proposed for defining new and/or sibling species within the Z. normani species complex. Expand
A new species of Zeuxo (Crustacea: Peracarida: Tanaidacea) from Japan, with remarks on carapace pigmentation as a potentially useful taxonomic character
Z. ezoensis specimens from four localities in Hokkaido showed Kimura 2-parameter divergences of 0–0.6–1.5% within and between populations, respectively, and the validity of using this pattern as a diagnostic character in Zeuxo taxonomy is discussed. Expand
Two new stygophilic tanaidomorphs (Peracarida, Tanaidacea) from Canary Islands and southeastern Iberian Peninsula
Two new species of stygophilic tanaidomorphs are described from El Hierro (Canary Islands) and the Spanish Mediterranean coast from samples collected both at caves and open marine environments, and represent the first styGophilic members of the genera Pseudotanais and Zeuxo. Expand
Difference in Size at Maturity in Annual and Overwintering Generations in the Tanaidacean Zeuxo sp. in Oshoro Bay, Hokkaido, Japan
Compared to the annual group, females in the overwintering group reproduced at larger minimum and average body sizes, and males began to express enlarged chelae, a secondary sexual character, at a larger size; the difference in size at maturity may be related to the differences in water temperature during the main period of growth and maturation.

A new species of Zeuxo (Crustacea: Tanaidacea) from the French Atlantic coast
A new species of tanaidacean of the genus Zeuxo is described from 105 specimens dredged from the shallow inshore benthic marine fauna from Arcachon, western France, with a combination of a 7-articled uropod with elongate articles in the adult. Expand
The new and the old: littoral tanaidomorph Tanaidacea (Crustacea: Peracarida) from the Andaman Islands, Indian Ocean
A redescription of the leptocheliid Konarus crassicornis is given, discussing its close similarity to the generotype, K. cheirus, and two new species of tanaidaceans are described, one of the tanaid genus Zeuxo, showing similarities to Z. (Parazeuxo) kurilensis and representing the first anatanaid to be recorded from the region. Expand
A re-assessment of Hexapleomera Dudich, 1931 (Crustacea: Tanaidacea: Tanaidae), with designation of three new species
The tanaid genus Hexapleomera has long been considered to be monotypic, comprising a cosmopolitan species predom-inantly commensal on turtles, or, more rarely, manatees. Recent discovery of materialExpand
Shallow water tanaidaceans (Crustacea: Peracarida: Tanaidacea) from New Caledonia and the Loyalty Islands
The Pacific collections by the MUSORSTOM campaigns of the Paris Museum over the last twenty years include a total of four species of Tanaidacea from shallow waters of the New Caledonia region and all new to science, including a species with unusual cheliped carpus morphology which is placed in a new genus as Konarus cheiris.

Littoral Tanaidacea (Crustacea: Peracarida) from Macaronesia: allopatry and provenance in recent habitats

The Macaronesian Islands in the mid-Atlantic pose a number of questions relating to their colonization by littoral tanaidaceans, as these taxa have no obligate dispersive phase. Recent surveys of theExpand
Untying the Gordian Knot: on Tanais novaezealandiae Thomson (Crustacea, Tanaidacea, Tanaidae) from New Zealand, with descriptions of two new Zeuxoides species
Two new species which show a close resemblance to some newly-described Australian species and Zeuxoides helleri support the view that the Australasian/New Zealand region is a hot-spot for species richness within the Tribe Anatanaini and the confused taxonomy of the Subfamily Tanainae is remarked on. Expand
Tanaidacea (Crustacea) from Macaronesia III. The shallow-water Tanaidomorpha from the Cape Verde archipelago
Three new species of Tanaidacea are described from the Cape Verde archipelago in the Mid-Atlantic, collected during thesampling program of the Laboratory of Marine Community Ecology and EvolutionExpand
Tanaidomorphan Systematics—Is it Obsolete?
The number of articles in the uropodal rami is found to be ambiguous, owing to partial fusion of articles, and the taxonomic concepts that were suggested by Sieg for the above-mentioned families fail when setal homologies are critically evaluated. Expand
Shallow water Tanaidae (Crustacea: Tanaidacea) of Australia
Investigation of shallow reef habitats around Australia revealed an extremely rich tanaid fauna, with a total of 21 species in the family now recognised from the Australian continent and Tasmania— about one-third of tanaids known worldwide. Expand
