ALMEIDA & FACELUCIA B. C. SOUZA Museu de Zoologia da Universidade Federal da Bahia, Instituto de Biologia, Universidade Federal da Bahia, Avenida Barão de Jere- moabo s/n, Campus Universitário, Ondina, Salvador–BA, Brazil, 40170–115. E-mail: [email protected]; [email protected] Abstract Two new species of cheilostome bryozoans are described from Bahia and Espírito Santo States, Brazil—Calyptooecia conuma n. sp. and Hippotrema fissurata n. sp. Both genera are registered for the first time in the South Atlantic Ocean. Inter alia, Calyptooecia conuma n. sp. is characterized by the presence of dimorphic brooding zooids with relatively small orifices and no perioral tubercles, contrasting with bigger non-brooding zooids having larger orifices surrounded by perioral tubercles. Hippotrema fissurata n. sp. differs from congeners in colony morphology and colour, in details of the ooecium and in zooidal metrics. Specimens were collected on varied substrata, commonly calcareous nodules and shells as well as other bryozoans and sponges. Key words: Bryozoa, Cheilostomata, Calyptooecia, Hippotrema, new species, taxonomy, Brazil Introduction Bryozoans constitute a phylum of colonial lophotrochozoan animals that are predominantly marine and occur in all the world’s seas from the shore to abyssal depths (Dick et al. 2006). -

Compared to other phyla, little is known about their phylogenetic relationships at both lower and higher taxonomic levels. Hence, an effort is being made to elucidate their phylogenetic relationships. Here, we present newly sequenced nuclear and mitochondrial genes for 21 cheilostome bryozoans. Combining these data with existing orthologous molecular data, we focus on reconstructing the phylogenetic relationships of Fenestrulina and Microporella, two species-rich genera. They are currently placed in Microporellidae, defined by having a semicircular primary orifice and a proximal ascopore. -

The class Gymnolaemata is represented by bryozoans of the orders Ctenostomatida (Amathia caspia, Paludicella articulata, and Victorella pavida) and Cheilostoma- tida (Conopeum grimmi and Lapidosella ostroumovi). Two species (Conopeum grimmi and Amatia caspia) are Caspian endemics. Lapidosella ostroumovi was identified in the Caspian Sea for the first time. The systematic position, illustrated morphological descriptions, and features of ecology of the species identified are pre- sented. -

Diversity and Distribution of Deep Sea Bryozoa from Andaman Waters
926 Research in Marine Sciences Volume 6, Issue 2, 2021 Pages 926 - 936 Diversity and distribution of deep sea Bryozoa from Andaman waters Mohammed Naufal∗, and Kadeparambil Arjunan Jayaraj Department of Ocean Studies and Marine Biology, Pondicherry University, Port Blair, India Received: 2021-01-11 Accepted: 2021-04-25 Abstract In Andaman waters, the phylum bryozoa was understudied. Considering the geographical and related maritime aspects, an extensive study on marine bryozoa is most needed in this island waters. Aiming to find out the distribution and diversity of the deep-sea bryozoan of Andaman waters, a study was carried out in the seven sites of the Indian Exclusive Economic Zone (EEZ) of Andaman Sea. The samples were dredged using sampling gears, during the scientific cruise of FORV Sagar Sampada along Andaman Islands on November, 2017. The investigation was yielded eighteen Cheilostome bryozoan species. A total of 18 species belonging to 11 genera of 10 families coming under 7 super families and 1 suborder of Cheilostomes were listed out from the study. Out of this result, 15 species are first reports from the Indian EEZ. This study has also occupied the paucity of the study of distribution and diversity of deep sea bryozoan from Andaman Islands, after nine decades. Keywords: Bryozoa; Cheilostomes; Deep Sea; Andaman waters. 1. Introduction are sometimes called sea mats, as they were found as flat encrusting forms on boulders and Bryozoans are small, aquatic organisms that rocks. Erect, cord like forms are often named as form habitually colonial structure by the lace corals. They have worldwide occurrence interconnected individuals. -

We examined the type specimens and historical collections holding puzzling Atlantic and Mediterranean material belonging to the genus Schizoretepora Gregory, 1893. We performed a detailed study of the colonial characters and re-describe the resulting species and those that have rarely been found or have poor original descriptions. As a result of this revision, nine species are found in the northeast Atlantic and Mediterranean. Six of them are re-described and illustrated: S. aviculifera (Canu & Bassler, 1930), S. calveti d’Hondt, 1975, S. imperati (Busk, 1884), S. sp. nov.? (= S. -
