Original Description GenusPsammosiphonella. – Tubular arenaceous monothalamous test of round or elliptical cross-section, straight or bent, of even diameter or slightly tapering in one direction without any distinct swelling in any part of the tube; the interior of the tube even, not constricted; apertures at two ends. Suborder Monothalamia [family not given]. Extra details from original publication Group of tubular Monothalamia. – Tubular, cylindrical, fusiform, ovoid, semiglobular to globular Monothalamia open at two opposite ends. Typically free, non-attached, bottom-living foraminifera, mostly marine, few living in fresh water, exceptionally parasitic in other foraminifera.
The so-defined tubular Monothalamia include several genera of Cushman’s families Allogromiidae, Astrorhizidae and Rhizamminidae; or they include all Amphitreminae (family Lagynidae) and parts of Astrorhizinae (family Astrorhizidae) in Galloway’s systematics.
Subfamily Psammosiphonellinae Avnimelech. – Tubular Monothalamia, the agglutinated test of which is composed of mineral grains, mostly quartz. Apertures at both ends. Type genus: Psammosiphonella.
Other species:
Recent:
Psammosiphonella capbritonensis (de Folin) = Bathysiphon capbritonensis de Folin, 1886;
The generic position of the following species remains uncertain, because their definition gives no sufficient and exact details: a) Bathysiphon capillare de Folin, 1886, has apparently only one aperture; b) the description of Bathysiphon rufescens Cushman gives no basis for exact opinion.
Synonymy:
Astrorhiza [Sandahl] of authors (part).
Bathysiphon Sars of authors (part).
Marsipella Norman of authors (part).
Rhabdammina [Sars] of authors (part).
