The Genus Monocoryne (Hydrozoa, Capitata): Peculiarities Of
Published in collaboration with the University of Bergen and the Institute of Marine Research, Norway The genus Monocoryne (Hydrozoa, Capitata): peculiarities of morphology, species composition, biology and distribution Sofia D. Stepanjants, Bengt O. Christiansen, Armin Svoboda & Boris A. Anokhin SARSIA Stepanjants SD, Christiansen BO, Svoboda A, Anokhin BA. 2003. The genus Monocoryne (Hydrozoa, Capitata): peculiarities of morphology, species composition, biology and distribution. Sarsia 88:97– 106. A revision of the genus Monocoryne was undertaken following analysis of peculiarities noted in earlier descriptions of the nominal species. Type specimens of Monocoryne gigantea from northern Norway and Monocoryne minor from South Africa were examined. In addition, non-type material from the Arctic Ocean, Antarctic Seas and the Kuril Islands was studied, and descriptions of species from Alaska and the Canadian Archipelago were investigated. A new diagnosis of the genus Monocoryne, provided here, was a necessary outcome of these studies. Most importantly, hydroids (in species of the genus) are colonial or solitary which differ from Bonnevie’s original diagnosis. The collection of solitary polyps is a result of the tenuous nature of the colonies, which tend to fall to pieces. Species of Monocoryne are found in Arctic, Antarctic and temperate waters of the northern and southern hemispheres, and the genus may thus be regarded as bipolar. Although recognized species of Monocoryne are quite similar morphologically, four of them are recognized here to be valid based on current evidence. This conclusion is also supported by their distribution patterns. Sofia D. Stepanjants & Boris A. Anokhin, Zoological Institute of the Russian Academy of Sciences, 199034 St. -

CNIDARIA Corals, Medusae, Hydroids, Myxozoans
FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W.

SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell. -

Previous phylogenetic analyses show strong support for Hydroidolina monophyly, but the relationships between and within its subgroups remain uncertain. In an effort to further clarify hydroidolinan relationships, we performed phylogenetic analyses on 97 hydroidolinan taxa, using DNA sequences from partial mitochondrial 16S rDNA, nearly complete nuclear 18S rDNA and nearly complete nuclear 28S rDNA. Our findings are consistent with previous analyses that support monophyly of Siphonophorae and Leptothecata and do not support monophyly of Anthoathecata nor its component subgroups, Filifera and Capitata. Instead, within Anthoathecata, we find support for four separate filiferan clades and two separate capitate clades (Aplanulata and Capitata sensu stricto). Our data however, lack any substantive support for discerning relationships between these eight distinct hydroidolinan clades. -

Phylogeny of Capitata and Corynidae (Cnidaria, Hydrozoa) in light of mitochondria! 16S rDNA data ALLEN G. COLLINS*, SILKE WINKELMANN, HEIKE HADRYS & BERND SCHIERWATER Accepted: 14 April 2004 Collins, A. G., Winkelmann, S., Hadiys, H. & Schiei-water, B. (2004). Phylogeny of Capitata (Cnidaria, Hydrozoa) and Coiynidae (Capitata) in light of mitochondrial 16S rDNA data. — Zoologica Scripts, 34, 91-99. New sequences of the partial rDNA gene coding for the mitochondrial large ribosomal sub- unit, 16S, are derived ffom 47 diverse hydrozoan species and used to investigate phylogenetic relationships among families of the group Capitata and among species of the capitate family Corynidae. Our analyses identiiy a well-supported clade, herein named Aplanulata, of capitate hydrozoans that are united by the synapomorphy of undergoing direct development without the ciliated planula stage that is typical of cnidarians. Aplanulata includes the important model organisms of the group Hydridae, as well as species of Candelabiidae, Corymorphidae, and Tubulariidae. The hypothesis that Hydridae is closely related to brackish water species of Moerisiidae is strongly controverted by 16S rDNA data, as has been shown for nuclear 18S rDNA data. The consistent phylogenetic signal derived from 16S and 18S data suggest that both markers would be useful for broad-scale multimarker analyses of hydrozoan relation- ships. Coiynidae is revealed as paraphyletic with respect to Polyorchidae, a group for which information about the hydroid stage is lacking. Bicorona, which has been classified both within and outside of Corynidae, is shown to have a close relationship with all but one sampled species of Coryne. The coiynid genera Coiyne, Dipurena, and Sarsia are not revealed as mono- phyletic, further calling into question the morphological criteria used to classiiy them. -

SUMMARY: This study provides a systematic account of the hydrozoan species collected up to now in the Mediterranean Sea. All species are described, illustrated and information on morphology and distribution is given for all of them. This work is the most complete fauna of hydrozoans made in the Mediterranean. The fauna includes planktonic hydromedusae, benth- ic polyps stages and the siphonophores. The Hydrozoa are taken as an example of inconspicuous taxa whose knowledge has greatly progressed in the last decades due to the scientific research of some specialists in the Mediterranean area. The num- ber of species recorded in the Mediterranean almost doubled in the last thirty years and the number of new records is still increasing. The 457 species recorded in this study represents the 12% of the world known species. The fauna is completed with classification keys and a glossary of terms with the main purpose of facilitating the identification of all Meditrranean hydrozoan species. Key words: Hydrozoa, hydromedusae, hydropolyps, siphonophores, taxonomy, systematics, fauna, Mediterranean. -

These data have substantial power to discern among many of the competing hypotheses of relationship derived from prior work. Moreover, LSU data provide strong support at key nodes that were equivocal based on other molecular markers. Combining LSU sequences with those of the small subunit of the nuclear ribosome (SSU or 18S), we present a detailed working hypothesis of medusozoan relationships and discuss character evolution within this diverse clade. -
