| Summary: | Flexammina gen. nov. Etymology. ‘ Flex ’ from English ‘flexible’ denoting the plasticity of the test shape; ‘ ammina ’—from the Greek ‘psammon’ meaning ‘sand’—refers to the agglutinated mineral material covering the test. Type species. Flexammina islandica. Diagnosis. Test free or attached, monothalamous. The test shape is subspherical or elongated when free, domelike when attached; aperture subcircular to irregular, surrounded by a short collar; test wall flexible, formed by a thick layer of mineral grains with an underlying layer of organic material. Phylogenetic position. The type species F. islandica branches in the clade M of monothalamous foraminifera, based on the phylogenetic analysis of SSU rDNA gene sequences. Remarks. There are some monothalamids that morphologically resemble Flexammina. Of these, Leptammina Cedhagen et al. (2009) is a genus from the deep Weddell Sea, with a similar test morphology possessing a flexible spherical test composed of fine mineral particles and a collared aperture. ... : Published as part of Voltski, Ivan & Pawlowski, Jan, 2015, Flexammina islandica gen. nov. sp. nov. and some new phylotypes of monothalamous foraminifera from the coast of Iceland, pp. 245-259 in Zootaxa 3964 (2) on page 247, DOI: 10.11646/zootaxa.3964.2.5, http://zenodo.org/record/236970 ... |
