Genus Microeciella Taylor and Sequeiros, 1982

Type species: Microeciella beliensis Taylor and Sequeiros, 1982 , Toarcian , Jurassic, Belchite, Spain .

Remarks.— Microeciella was introduced by Taylor and Sequeiros (1982) for bereniciform cyclostomes with simple ovoidal gonozooids that had previously been incorrectly assigned to Microecia (a subjective junior synonym of Plagioecia ). The status of the genus was recently clarified by Taylor and Zatoń (2008) who argued that Recent species placed in Eurystrotos Hayward and Ryland, 1985 actually belonged in Microeciella . Five new species of Microeciella are recognized among the material studied here. They can be distinguished using the following key:

1. autozooidal frontal wall width <200 µm 2

autozooidal frontal wall width> 200 µm 4

2. ooeciopore located distally of brood chamber M. annae ooeciopore subterminal 3

3. brood chamber elongate, about 1.5 × longer than wide M. mokrskoensis brood chamber equidimensional M. maleckii

4. ooeciopore significantly smaller than autozooidal aperture M. kuklinskii ooeciopore about same size as an autozooidal aperture M. magnopora
