The New and Reinstated Genera of Agglutinated Foraminifera published between 1996 and 2000 MICHAEL A. KAMINSKI Department of Earth Sciences, University College London, Gower Street, London, WC1E 6BT, U.K. and KLFR, 3 Boyne Avenue, Hendon, NW4 2JL, U.K. [m.kaminski@ucl.ac.uk] ABSTRACT During the four year period since the previous International Workshop on Agglutinated Foraminifera, some 33 genera of agglutinated foraminifera have been described as new, and an additional six genera have been reinstated by various authors. This brings the total number of new and reinstated genera to 121 since the publication of “Foraminiferal Genera and their Classification” by Loeblich & Tappan (1987). INTRODUCTION The purpose of this paper is to continue the compila- tion of validly described and reinstated genera of agglutinated foraminifera published after Loeblich & Tappan’s (1987) book “Foraminiferal Genera and their Classification”. In this paper, I provide a list of the newly described genera of agglutinated foraminifera published in the accessible literature, as well as several genera that were synonymised by Loeblich & Tappan, but have been newly reinstated. The current work is a continuation of a previous compilation containing 94 valid genera (Kaminski, 2000), and encompasses the years 1996 to 2000, inclusive. It is my intention to update these "appendices" to Loeblich & Tappan (1987) approximately every four years as a regularly occurring chapter in the IWAF proceedings volumes. The goal of this work is to review recent changes and updates to the taxonomy with the goal of stabilising the generic nomenclature of the agglutinated foraminifera. The full up-to-date list of the new and reinstated genera can be found in “Agglut-2001”, the database of agglutinated genera distributed in electronic form by the Grzybowski Foundation. The suprageneric affiliation of the genera follows Kaminski (this volume). Part 1 - Genera reinstated since the publication of Loeblich & Tappan (1987) KADRIAYINA Al-Najdi, 1975 Figure 1 Type species: Gaudryina gradata Berthelin, 1880, p. 24; OD(M). Kadriayina Al-Najdi, 1975, p. 3; SD, Holbourn & Kaminski, 1997, p. 51. Test elongated, initially with a short trochospiral or triserial stage, enlarging rapidly, later biserial. Cham- bers are subglobular, with depressed sutures. The test is rounded to ovoid in cross section. The wall is finely agglutinated, noncanaliculate, with calcareous cement. Aperture a low arch at the base of the aper- tural face. Aptian to Cenomanian; Indian Ocean; France. Figure 1. Type figure of Gaudryina gradata, from Berthelin (1880). Remarks. The emended description of Kadriayina by Holbourn & Kaminski (1997) differs somewhat from the original description of Al-Najdi (1975). Al-Najdi described this genus as "subconical, circular in cross- section throughout; wall arenaceous, grains relatively large". Al-Najdi based his description on the drawings of Gaudryina pupoides d'Orbigny by Chapman (1892, pl. 11, fig. 8), who regarded Berthelin's G. gradata as a junior synonym. Al-Najdi designated G. gradata as the type species of his new genus, but erroneously cited the authorship as Chapman. Our definition of the genus is based on the description and drawings of Berthelin (1880) as well as on specimens from DSDP/ODP sites in the Indian Ocean, which have inflated chambers in the biserial part. Berthelin (1880) described the wall of G. gradata as "rough", but our specimens are finely agglutinated. Loeblich & Tappan (1987) considered Kadriayina to be synonymous with Gaudryinopsis Podobina, 1975.
