Note: Geodinella robusta megasterra Lendenfeld, 1910 was also reported by de Laubenfels, 1932 as occurring in California. The Systema reports Geodinella as a junior synonym of Geodia.. The status of California Geodias is not satisfactory and needs intensive review. Lendenfeld reports 5 species from California, including G. agassizii, breviana, ovis, mesotrienella and mesotriaena (pg. 208A) but differences are minimal and suspect. A review is necessary. See. Pg 208 A, de Laubenfels, 1932 and Lendenfeld, 1910. Cited as Geodinella robusta by de Laubenfels.
Megascleres may include Oxeas or Plagiomonaenes but have other Tetracts as well.
