We describe two new genera and species of monothalamous Foraminifera from a coastal site in Balaclava Bay, Crimea. Nellya rugosa gen. and sp. nov. has an elongate, approximately oval test, 120–360 μm long, somewhat resembling a rice grain and with a single nipple-like apertural structure located at the distal end, which is often rather truncated. The wall is whitish, opaque, somewhat flexible and composed of jumbled mineral grains, mostly <10 μm in size, overlying an inner organic layer… 

Morphological and molecular diversity of monothalamids (Rhizaria, Foraminifera), including two new species and a new genus, from SW Greenland.

One new genus and two new species belonging to different clades from the Nuuk fjord system are described, adding to growing evidence that monothalamids are common and diverse in fjords and other high-latitude settings.

Soft-walled monothalamids (Rhizaria: foraminifera) of the Crimean shelf (Black Sea): taxonomic composition and inter-regional patterns of species diversity and distribution

ABSTRACT We present new data on monothalamous (single-chambered) foraminifera from the Black Sea Crimean shelf zone between Karkinitsky Gulf in the west to the area near Kerch in the east. Within

Flexammina islandica gen. nov. sp. nov. and some new phylotypes of monothalamous foraminifera from the coast of Iceland.

An integrated taxonomic approach is used, including morphological and molecular analysis, to examine the diversity of monothalamids in a shallow subtidal area on the coast of Iceland and establishes a new genus Flexammina and a new species, possessing a very pliable, finely agglutinated test capable of extreme shape transformations.

Taxonomic composition and distribution of soft-walled monothalamid foraminifera in the area of Zernov’s Phyllophora Field (NW Black Sea)

This work provides the first analysis of the taxonomic composition of monothalamids from this region and finds four species, Psammophaga sp.


Monothalamids are more resistant to hypoxia, they are found closer to the boundary of sulfidic waters, and they occupy deeper sediment layers, than other single-chambered foraminifera.

Selective zircon accumulation in a new benthic foraminifer, Psammophaga zirconia, sp. nov.

The ability of a foraminiferal species to select and accumulate zircons and other heavy minerals in their cytoplasm is reported here for the first time, together with the selection of otherheavy minerals already described in members of the genus Psammophaga.

Palaeoceanographic changes in Hornsund Fjord (Spitsbergen, Svalbard) over the last millennium: new insights from ancient DNA

Abstract. This paper presents a reconstruction of climate-driven environmental changes over the last millennium in Hornsund Fjord (Svalbard), based on sedimentological and micropalaeontological

Allogromiida are soft-shelled benthic foraminifera protected by thin proteinaceous shells only. They lack rigid calcareous or arenaceous structures and do not undergo fossilization. Some species of



Tinogullmia lukyanovae sp. nov.—a monothalamous, organic-walled foraminiferan from the coastal Black Sea

A new monothalamous foraminifera species from the Crimean and Caucasus regions of the Black Sea, characterized by a more or less symmetrical, spindle-shaped to cylindrical, organic-walled test with two terminal apertural structures, usually in the form of rounded or more elongate, nipple-like projections, is described.

The monothalamous foraminiferan Tinogullmia in the Black Sea

INTRODUCTION The organic-walled allogromiid genus Tinogullmia was established by Nyholm (1954) based on a single species, T. hyalina, from the Gullmar Fjord on the Swedish west coast. This


It is suggested that these foraminiferans, which lack hard mineralized structures, are unable to fracture diatoms and remove their chloroplasts, rather, they ingest entire diatom as a form of chloroplast sequestration.

Vellaria zucchellii sp. nov. a new monothalamous foraminifer from Terra Nova Bay, Antarctica

The description of this new organic-walled monothalamous foraminiferal species further documents the high taxonomic diversity of these delicate and abundant protists in the polar benthic communities.

A New Allogromiid Genus (Rhizopoda: Foraminiferida) from the Vellar Estuary, Bay of Bengal

This paper reports what we believe to be the first record of allogromiid foraminifers from coastal Indian waters. Two species from the Vellar Estuary on the east coast of India south of Madras are

Goodayia Rostellatum Gen. N., Sp. N. (Protozoa) - A Monothalamous Foraminiferan from the Black Sea

The shape and size of the test, the presence of two membranes, and the single terminal aperture are the features reminiscent of the genera Gloiogullmia and Rhynchogromia, however, the new genus has significant differences from these taxa, notably the absence of any foreign mineral or organic particles adhering to the test wall and the beak-shaped apertural structure.

Modern benthic foraminifers at Northern shallow sites of Adriatic Sea and soft-walled, monothalamous taxa: a brief overview

Sediment subsamples (0-2cm layer, >63 mu m fraction) from box cores taken at foul sites (Slits 120, 121. 122, 123) located along a transect in the Gulf of Trieste (water depth range 8-22m) were

Soft-shelled monothalamous foraminifera at an intertidal site on the south coast of England

There have been a number of studies of modern benthic foraminiferal assemblages at intertidal sites around the UK (Murray, 1991). Among the localities are several on the south coast of England:

Monothalamous foraminifera from Admiralty Bay, King George Island, West Antarctica

During the late 2007 austral summer, 20 sediment samples were collected in Ad− miralty Bay (King George Island, South Shetlands, West Antarctica) from 8 down to 254 m water−depth (mwd). The samples

Molecular data reveal high taxonomic diversity of allogromiid Foraminifera in Explorers Cove (McMurdo Sound, Antarctica)

Comparison of data with sequences of non-Antarctic allogromiids suggests that Explorers Cove species might be endemic and only distantly related to comparable northern hemisphere fauna.
