ABSTRACT
In Part 2 those ostracods belonging to the Treposellidae, Beyrichiidae and Beyrichiacea Family Uncertain are described, and are referred to a total of 17 genera and 35 named species. The Treposellidae comprises six genera (one new) and seven species (four new). The Beyrichiidae comprises Beyrichiinae (five genera, one new; one new subgenus; and 19 species, five new) and Kloedeniinae (four genera; and six species). Beyrichiacea Family Uncertain comprises two genera (one new) and three species (one new). A total of seven other forms are referred to the Treposellidae, Beyrichiidae and Beyrichiacea Family Uncertain under open nomenclature or are simply recorded. The biostratigraphy of British Silurian Beyrichiacea and their palaeoecological and palaeobiogeographical context is also documented.
RÉSUMÉ
Dans la 2ème partie, les ostracodes appartenant aux Treposellidae, Beyrichiidae et Beyrichiacea Famille Incertaine sont décrits et attribués au total à 17 genres et 35 espèces nommées. Les Treposellidae comprennent six genres (l’un d’eux est nouveau) et sept espèces (dont quatre nouvelles). Les Beyrichiidae comprennent les Beyrichiinae (cinq genres, un nouveau; un sous-genre nouveau; et 19 espèces, dont cinq sont nouvelles) et les Kloedeniinae (quatre genres; et six espèces). Les Beyrichiacea Famille Incertaine comprennent deux genres (un nouveau) et trois espèces (une nouvelle). Un total de sept autres formes sont attribuées aux Treposellidae, Beyrichiidae et Beyrichiacea Famille Incertaine en nomenclature ouverte ou sont simplement cités. La biostratigraphie des Beyrichiacea siluriens britanniques et leur contexte paléoécologique et paléobiogéographique sont aussi documentés. [Translation by Yves Candela.]
KURZFASSUNG
In Teil 2 werden die zu den Treposellidae, den Beyrichiidae und den Beyrichiacea incertae familiae, gehörenden Ostracoden beschrieben und auf insgesamt 17 Gattungen und 35 benannte Arten verwiesen. Die Treposellidae umfassen sechs Gattungen (eine neue) und sieben Arten (vier neue). Die Beyrichiidae umfassen die Beyrichiinae (fünf Gattungen, eine neue; eine neue Untergattung; 19 Arten, fünf neue) und die Kloedeniinae (vier Gattungen und sechs Arten). Die Beyrichiacea incertae familiae umfasst zwei Gattungen (eine neue) und drei Arten (eine neue). Insgesamt sieben weitere Formen werden in offener Nomenklatur den Treposellidae, Beyrichiidae und Beyrichiacea incertae familiae zugeordnet oder nur dokumentiert. Die Biostratigraphie der Beyrichiacea aus dem britischen Silur und ihr paläoökologischer und paläobiogeographischer Kontext werden ebenfalls dokumentiert. [Translation by Renate Matze-Karasz.]
РЕЗЮМЕ
Во второй части описаны остракоды семейств Treposellidae, Beyrichiidae и Beyrichiacea familia incertae, которые относятся к 17 родам и 35 названным видам. Treposellidae включает шесть родов (один из них новый) и семь видов (четыре новых). Beyrichiidae включает Beyrichiinae (пять родов, один из них новый, а также один новый подрод и всего 19 видов, пять из них новыe) и Kloedeniinae (четыре рода и шесть видов). Семейство Beyrichiacea familia incertae включает два рода (один из них новый) и три вида (один новый). Всего семь других форм отнесены к семействам Treposellidae, Beyrichiidae и Beyrichiacea familia incertae по открытой номенклатурe или просто зарегистрированы. Задокументирована также биостратиграфия британских силурийских Beyrichiacea и их палеоэкологический и палеобиогеографический контекст. [Translation by Tõnu Meidla.]
ADDENDA AND ADDITIONAL ACKNOWLEDGEMENTS
All type and figured material from the author’s collection has been deposited in the Natural History Museum, London (prefixed BM in Part 1 and NHMUK in Part 2). All other relevant material from the author’s collection will also be housed in the Natural History Museum, London.
Notwithstanding the fact that the current International Code of Zoological Nomenclature recommends use of the suffix ‘-oidea’ for taxa at Superfamily level, herein Beyrichiacea is maintained for consistency with its use in Part 1 (Siveter Citation1980).
I am indebted to Dr Peter Crowther for his thorough editorial work and to Prof. Tõnu Meidla for his insightful review of the Part 2 manuscript. I thank Dr Yves Candela, Dr Renata Matzke-Karasz and Prof. Tõnu Meidla for translating the Abstracts into French, German and Russian respectively.
