Family Fistuliporidae Ulrich, 1882 View in CoL Genus Stellatoides nov.
Type species: Stellatoides muellertchensis gen. et sp. nov., by monotypy; see below.
Etymology: From Latin stellatus, star shaped; in reference to the presence of star-shaped maculae.
Diagnosis.—Colony encrusting, lamellar, often with multiple overgrowths. Maculae stellate with depressed centres. Autozooecia cylindrical with thin granular walls and complete diaphragms. Autozooecial apertures rounded. Lunaria triangular. Autozooecia separated by extrazooidal vesicular skeleton. Acanthostyles occurring in roofs of vesicles.
Remarks.— Stellatoides gen. nov. differs from other known cystoporate bryozoans in having stellate maculae. Fistuliporella Simpson, 1897 resembles Stellatoides in the morphology of the autozooecia and vesicular skeleton. However, the new genus possesses long triangular lunaria unlike the semicircular ones found in Fistuliporella . Eridopora Ulrich, 1882 has long triangular lunaria but differs from Stellatoides in having smaller vesicles. Similar elongated maculae with depressed centres are known in Ceramella Hall and Simpson, 1887 , which belongs to the family Hexagonellidae Crockford, 1947 . However, maculae in Ceramella are not stellate, and this genus is characterised by a bifoliate colony shape contrasting with the encrusting colonies of Stellatoides gen. nov.
Stratigraphic and geographic range.—Lower Givetian (Middle Devonian) of the Rhenish Massif, Germany.
