Note: * Variously reported with a wide range in spicule measurements and types of Triradiates. (1) Sim & Bakus, 1986: Regular Triradiates 100 - 110 μm, (2) Bakus & Green,1987: Regular Triradiates 5 - 14 and 14-182 μm, (3) Sagittal Triradiates 23 - 66 μm, (4) Green & Bakus, 1994: Regular Triradiates, the size range varies considerably (from 9 - 97 to 40 - 182 μm, unpublished data). This could well be a complex of related species. Known from England.
