TL;DR: Eight adeonid species in two genera were detected and three are described as new species based on the branch width, size and morphology of frontal or suboral avicularia, shape and size of areolar pores, andsize of the spiramen.
Abstract: Adeonid bryozoans construct antler-like erect colonies and are common in bryozoan assemblages along the Japanese Pacific coast. The taxonomy of Japanese adeonid species, however, has not been studied since their original descriptions more than 100 years ago. In the present study, adeonid specimens from historical collections and material recently collected along the Japanese coast are examined. Eight adeonid species in two genera were detected, of which Adeonella jahanai sp. nov., Adeonellopsis parvirostrum sp. nov., and Adeonellopsis toyoshioae sp. nov. are described as new species based on the branch width, size and morphology of frontal or suboral avicularia, shape and size of areolar pores, and size of the spiramen. Adeonellopsis arculifera (Canu & Bassler, 1929) is a new record for Japan. Lectotypes for Adeonellopsis japonica (Ortmann, 1890) and Adeonella sparassis (Ortmann, 1890) were selected among Ortmann’s syntypes. Most species of Adeonellopsis around Japan have a southern distribution from Sagami Bay to Okinawa, while A. japonica shows a more northern distribution from Kouchi to Otsuchi. In contrast, Adeonellopsis arculifera was collected only from southwestern Japan. A key to Japanese adeonid species is provided.

TL;DR: The type species of the genus Laminopora, L. contorta, has been found to possess slightly dimorphic brooding zooids, which also occur in a more distinctive form in two South African species of Adeonella, A. bimunita and L. jellyae.
Abstract: Summary The type species of the genus Laminopora, L. contorta, has been found to possess slightly dimorphic brooding zooids, which also occur in a more distinctive form in two South African species, L. bimunita and L. jellyae. These last two species have been confused with one another and with another member of the family Adeonellidae, Adeonella pygmaea, which is redescribed. A further South African species of Adeonella, A. inaequalis, is unique in having a fenestrate growth form, which is otherwise found in the systematically distinct, but highly convergent family Adeonidae.

TL;DR: Detailed examination has shown enlarged brooding zooids with marked differences from autozooids in the internal structure of the peristomes and in the occurrence of a primary calcified orifice in the genus Adeona.
Abstract: Bock, P.E., and Cook, P.L. 2004. Dimorphic brooding zooids in the genus Adeona Lamouroux from Australia (Bryozoa: Cheilostomata). Memoirs of Museum Victoria 61(2): 129‐133. The genus Adeona is a characteristic and common part of the Australian shelf fauna, extending to the tropical IndoWest Pacific. The genus first appears in the fossil record of the Miocene of south-eastern Australia. Zooid dimorphism has been recognised initially from subtle differences in the external appearance, which have not been described previously. Detailed examination has shown enlarged brooding zooids with marked differences from autozooids in the internal structure of the peristomes and in the occurrence of a primary calcified orifice.
