Description of Rhabdonella amor
provided by BioPedia
Tintinnid ciliate, lorica length 77-92 microns, external diameter of mouth 45-55 microns. It varies in shape, but the pedicel is not usually as well marked as in the other species. The oral flare is only slightly expanded. There are 30-44 ribs, usually running in a left-handed spiral on the foot of the bowl. The fenestrae, when present, are small and sometimes difficult to see. In many specimens, the meshes at the oral lip are large but these rapidly give way to small meshes and the structure over most of the bowl is very fine.
