THE A\T-~RCTIL RESEARCH SERIES is designed to provide a medium for presenting authoritati~e reports on the extensile and detailed scientific research work being carried out in Antarctica. The series lias been successful in eliciting contributions from leading research scientists engaged in antarctic investigations; it seeks to maintain high scientific and publication standards. The scientific editor for each volume is chosen from among recognized authorities in the discipline or theme it represents, as are the reviewers on whom the editor relies for advice.Eeginning uith the scientific investigations carried out during the International Geophysical Year, reports of research results appearing in this series represent original contributions too lengthy or other~+ise inappropriate for publication in the standard journals. In some cases an entire volume is devoted to a monograph. The material published is directed not only to specialists actively engaged in the ~+ o r k but to graduate students, to scientists in closely related fields, and to interested laymen versed in the biological and the physical sciences. Many of the earlier volumes are cohesive collections of papers grouped around a central theme. Future volumes may concern themselves with regional as well as disciplinary aspects. or 1% ith a comparison of antarctic phenomena ~+ i t h those of other regions of the globe. But the central theme of Antarctica nil1 dominate.In a sense, the series continues the tradition dating from the earliest days of geographic exploration and scientific expeditions-the tradition of the expeditionary volumes which set forth in detail everything that Nas seen and studied. This tradition is not necessarily outmoded, but in much of the present scientific mork one expedition blends into the next, and it is no longer scientifically meaningful to separate them arbitrarily. Antarctic research has a large degree of coherence; it deserves the modern counterpart of the expeditionary volumes of past decades and centuries which the Antarctic Research Series provides.
The coronuloid barnacle family-group names Cylindrolepadinae, Stomatolepadinae, Chelolepadinae, Cryptolepadinae and Tubicinellinae of Ross & Frick, 2007 are considered nomen nudum according to Article 8.6 of the International Code of Zoological Nomenclature, but appear in several subsequent published works and internet taxonomic databases. It is the purpose of this communication to rectify this situation. These five subfamilial names are proposed and defined herein anew, as Cylindrolepadinae subfam. nov., Stomatolepadinae subfam. nov., Chelolepadinae subfam. nov., Cryptolepadinae subfam. nov. and Tubicinellinae subfam. nov. The remaining valid family-group names within the Coronuloidea are also listed and defined herein.
The coral-eating barnacle Hoekia monticulariae (Gray, 1831), the only internal parasite among the Thoracica described to this day, is characterized by an irregularly-shaped shell nestled cryptically between the polyps of the hermatypic coral Hydnophora Fischer, 1807, which occurs throughout most of the Indo-West Pacific. Because of its protean form, cirripedologists have failed to appreciate the diversity of taxa related to Hoekia, a presumed monotypic genus. We describe seven new species divided between Hoekia and three new genera, Eohoekia, Parahoekia, and Ahoekia for which the Tribe Hoekiini is proposed. As in other pyrgomatids, calcareous overgrowth by the coral is inhibited around the edge of the wall and aperture. But in Hoekiini a pseudopolyp, upon which the barnacle feeds with modified trophi, covers the wall and aperture. Furthermore, rather than articulating with a calcareous basis, the wall is suspended in coral tissue. Its hypertrophied lateral margin ( = basal margin), in contact with the host’s tissue, is the site where metabolic activities are inferred to take place. In Hoekia and Ahoekia, the wall develops simple or connecting tubes that lead to openings in the margin, which serve as circulatory pathways. A hypertrophied margin and elaborated circulatory system suggests that the Hoekiini may not be wholly dependent on feeding directly on host tissue and/or coelenteronic material, but may also be absorptive parasites. Although other pyrgomatids, in the tribes Pyrgopsellini nov. and Pyrgomatini nov., exercise some control over their hosts by an apertural frill and through discontinuities between the shell and basis, they are still planktotrophic.
Tesseropora and Tetraclitella. subgenera of Telraclita, are elevated to full generic status ir the absence of intergrading major characters. Newmanella gen. nov. is proposed for Telraclita (Telraclita radiata (Bruguiere, 1789) and Tesseroplax gen. nov. for Telraclita ( Tesseropora ) unisemita Zullo. 1968. On th< basis of shell characters the five genera here recognized fall into two groups. Monometric growth, allometry 01 the carina, and non-tubiferous radii characterize Tesseropora, Tesseroplax, and Telraclita; diametric growth isometry of the wall plates, and tubiferous radii characterize Tetraclitella and Newmanella. Both Tesseropla.\ and Tetraclita are considered later derivatives from the Tesseropora stock; but Tetraclitella and Newmanellc from a tesseroporan precursor. New distributional records for Newmanella radiata include the Bahamas Puerto Rico, Dominica, and Venezuela. Apparently the antenniform ramus of cirrus III in N. radiata play; some role during the reproductive cycle, but its exact function is unknown.RESUMEN. -Tesseropora y Tetraclitella, subgenero de Tetraclita. estan elevados al estado generico en a ausencia de intergradacion caracteres mayores.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
