The tantulus larva ofMicrodajus langi is redescribed using Scanning Electron Microscopy. Thoracopods 2–5 have poorly developed but fully armed endites. Thoracopods 1–5 are biramous, with each ramus represented by a minute segment. A new species,M. pectinatus, is described from a tanaid host collected in the Rockall Trough, off the west coast of Scotland. A system of homologies for the portopodal segments of the thoracopods of the tantulus larva is proposed. Some aspects of the musculature of the adult male are described for the first time.

Asterocheres reginae, a new species of parasitic copepod (Siphonostomatoida: Asterocheridae) from a sponge in Belize

Ano: 1989

URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=7072

Asterocheres reginae n. sp., of the family Asterocheridae, is described from the spongeAgelas clathrodes (Schmidt) collected at Carrie Bow Cay, Belize. It inhabits the internal canal system of its sponge host. A detailed description of both sexes is presented, and emphasis has been placed on the recognition of homologies between the limb segments and armature elements in accordance with the new evolutionary scheme established by Huys & Boxshall (1991).

A redescription of Cumoniscus Bonnier, 1903 (Crustacea: Tantulocarida) from a cumacean host in the Bay of Biscay

Cumoniscus kruppi Bonnier, the only tantulocarid known from a cumacean host, is redescribed from a tantulus larva collected from the Bay of Biscay. The host is a male leuconid cumacean. This genus is placed in the family Deoterthridae, and can be distinguished from other genera by the pore pattern on the cephalic shield, the reduced setae on the sixth legs and the presence of tiny curved spinules on the endopod of thoracopods 2 to 5.

The rediscovery of Cyclopicina longifurcata (Scott) (Copepoda: Cyclopinidae) in deep water in the North Atlantic, with a key to genera of the subfamily Cyclopininae

Ano: 2001

URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=6452

The marine cyclopoid, Cyclopicina longifurcata (Scott) is redescribed on the basis of the holotype and a second female, recently collected in deep water in the North Atlantic off the Azores. Cyclopicina is one of the most primitive cyclopoids known, displaying many of the extreme plesiomorphic character states in the family Cyclopinidae. A key to genera of the subfamily Cyclopininae is presented and three new genera, Herbstina, Erythropolites, and Glareolina, are established.

New family of deep-sea planktonic copepods, the Paralubbockiidae (Copepoda: Poecilostomatoida)

The deep-sea planktonic copepod Paralubbockia longipedia is redescribed from the type specimens, and a new family of Poecilostomatoida is proposed to accommodate it. The Paralubbockiidae fam. nov. is characterized by two unique plesiomorphies, the ventrally located fifth legs and the retention of a separate maxillulary palp, and by the apomorphic states of the endopods of the swimming legs and of the antenna. The sister group of the Paralubbockiidae is identified as the family Oncaeidae. These are the only two poecilostomatoid families that have retained a vestige of the geniculation mechanism in the antennules of the male. The genus Laitmatobius Humes is here regarded as incertae sedis within the lineage comprising the Oncaeidae and the...

Discovery of Centobnaster humesi, new genus, new species (Erebonasteridae), the most primitive poecilostomatoid copepod known, in New Caledonian deep waters

Palavras-chave: Oncaeidae; Paralubbockiidae.

Ano: 1989

A new genus, Centobnaster, is proposed to accommodate a single female collected from deep water northeast of New Caledonia. Centobnaster humesi, new species, is placed in the family Erebonasteridae (Poecilostomatoida) on account of the distinct palp on the mandible and the external structure of the female genital system, comprising ventral paired copulatory pores and dorsolateral gonopores. Centobnaster is considered the most primitive poecilostomatoid copepod known today because of the combined presence of 7-segmented antennules, a separate palp and unmodified gnathobase on the mandible, ventrally located paired copulatory pores, and midventral fifth legs jointed by an intercoxal sclerite. The...

Lack of attention to determining the homology of character states is recognized as being responsible for the ever increasing numbers of phylogenetic schemes for the Crustacea that appear and disappear so rapidly. Detailed study of musculature. segmentation and setation of the limbs of all 10 orders of copepods revealed numerous phylogenetically informative characters. based on segmental fusion patterns and the presence of individually identified setation elements. Simple counts of limb segments (or of setae) were found to be virtually useless for constructing phylogenies in the copepods. This conclusion can probably be extended to other crustacean groups.

A new genus and species of Tantulocarida (Crustacea: Tantulocarida) parasitic on a harpacticoid copepod from the Skagerrak

Ano: 1992

URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=7238

The new genus and species. Boreotuntulus kunzi, is described from Cylindropsyllus laevis, caught off the isle of Bonden, Bohaslän, Skagerrak. It is placed in the Deoterthridae on the basis of its larval characters. It can be distinguished form other genera by the presence of a distinct praecoxal segment carrying the endite on larval thoracopods2 to 5. This is the second tantulocaridan to be recorded in Scandinavian waters.

New tantulocarid, Stygotantulus stocki, parasitic on harpacticoid copepods, with an analysis of the phylogenetic relationships within the Maxillopoda

Ano: 1988

URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=7057

A new genus of Tantulocarida, Stygotantulus, is described based on material from an anchialine pool on Lanzarote, Canary Islands. It is the most primitive tantulocarid known and is ectoparasitic on representatives of at least two families of harpacticoid copepods. It is distinguished by the presence of 7 abdominal somites in the tantulus larva. The musculature of the penis on trunk somite 7 of the male suggests that it is derived by modification of the seventh thoracopods. The importance of trunk somite numbers in maxillopodan systematics is reexamined and an attempt is made to apply the concept of homology to the developmental processes determining somite numbers. The classification of the Crustacea, including the Tantulocarida, proposed by Starobogatov...
