Publication
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. Cedhagenia saltatus gen. and sp. nov. has
an approximately lenticular test, 150–300 µm long, with a
single aperture usually associated with a short, delicate,
slightly flared extension of test. The wall is whitish,
flexible, translucent with shiny highlights, and composed
of a thin layer of plate-like mineral grains, mostly <5 µm
in size, overlying an inner organic layer. In both N. rugosa
and C. saltatus, the cytoplasm is finely granular, without
stercomata. A third species, identified as Vellaria pellucidus
Gooday and Fernando 1992 and closely resembling
the type material of this species from the Vellar Estuary
(India), occurs occasionally in our Balaclava Bay material.
Samples from another Crimean Bay (Kazach’ya) yielded
an undescribed species of Psammophaga that is most
similar to a species from Southampton (UK). The
agglutinated wall encloses a cell body that is packed with
mineral grains. Analysis of the SSU rDNA sequences
obtained from these four species confirmed the position of
Psammophaga and Vellaria. Nellya is shown to be a sister
group to Vellaria + Psammophaga clade but its position is
not well resolved. Cedhagenia belongs to a very different
clade of monothalamous foraminiferans, which includes
also Ovammina and Cribrothalammina.
