Two new species of heavily calcified cyclostome bryozoans from the intertidal of Akkeshi Bay, Hokkaido, Japan

Cyclostome bryozoans are relatively uncommon in intertidal habitats, where they are subordinate to cheilostomes and ctenostomes. Those that do occur tend to have small colonies that are relatively weakly calcified. Here we describe two new species of intertidal cyclostomes from Akkeshi Bay in northern Japan that are unusual in having large, heavily calcified colonies. One of these - Favosipora ainui sp. nov. - is the first species of this genus recorded from Japan. The second species - Disporella ezoensis sp. nov. - although belonging to a genus well known from Japan and elsewhere globally, is unusual for Disporella in possessing colonies that are vivid red in colour.http://zoobank.org/urn:lsid:zoobank.org:pub:995903E6-9C07-436A-B788-29BDE2FD5A88
