Subfamily Semperiellinae Heding and Panning, 1954

Diagnosis. Calcareous ring tubular with long posterior prolongations, both ring and projections made up of a mosaic of small pieces; tentacles 20; body wall ossicles tables, each with a spire of 2 or 4 pillars.

Genera. Cladolella Heding and Panning, 1954 ; Massinium Samyn and Thandar, 2003 ; Neopentadactyla Deichmann, 1944 ; Neothyonidium Deichmann 1938 ; Pentadactyla Hutton, 1879 ; Phyrella Heding and Panning, 1954 .

Remarks. We note that Rowe and Richmond (2004) judged that Semperiella Heding and Panning, 1954 (family Semperiellinae Heding and Panning, 1954 ) is a junior synonym of Thyonidiella Heding and Panning, 1954 (family Phyllophorinae ). This refines the diagnosis for genera of subfamily Semperiellinae , removing the inclusion of genera with 15 tentacles. We query the inclusion in Semperiellinae of genus Phyrella Heding and Panning, 1954 with its calcareous ring that is not tubular and is similar to that in genera of Phyllophorinae . We note that Cladolella Heding and Panning, 1954 has a Massinium -like calcareous ring (see illustration in Heding and Panning 1954), 20 tentacles, and tables with 2-pillar spires, and might be considered to be a senior synomym of Massinium Samyn and Thandar, 2003 with its variety of body wall ossicles, although the tube feet are radial in Cladolella .
