A new species of Bostrichobranchus (Ascidiacea, Molgulidae) from the eastern tropical Atlantic

open access: greenZootaxa, 2008
During the ancient oceanographic expedition of the « Talisman » in 1883, several specimens of a new ascidian species of an uncommon genus of Molgulidae were dredged on a sedimentary bottom off Mauritania. This material was stored in the collections of the Muséum national d’Histoire naturelle where it was overlooked until recently. The good condition of

Bostricobranchus digonas Abbott (Ascidiacea, Molgulidae) in Paranaquá Bay, Paraná, Brazil: a case of recent invasion? [PDF]

open access: diamondRevista Brasileira de Zoologia, 2002
Bostricobranchus digonas Abbott, 1951 was discovered by dredging near Cotinga Island, Paranaguá Bay, Paraná (25º31'511"S, 48º28'714"W). Concentrated in a small area 1.5 m deep, the animals were collected by a Van Veen device. All sizes from 3 mm up to 2 cm in body diameter were recovered. This is the first report of a species of this genus in the South

DISTRIBUTION OF THE ENDOSYMBIONTNEPHROMYCESGIARD WITHIN THE ASCIDIAN FAMILY MOLGULIDAE

open access: closedThe Biological Bulletin, 1982
In various anecdotal reports, nineteenth and early twentieth century authors have asserted that microbial cells, "Nephromyces," are present in the renal sac of the ascidian Molgula. This study confirms the presence of such cells in the renal sac lumen of five Molgula species (M. manhattensis, M. arenata, M. complanata, M. citrina, M.

Phylogenetic analysis of phenotypic characters of Tunicata supports basal Appendicularia and monophyletic Ascidiacea

open access: yesCladistics, Volume 36, Issue 3, Page 259-300, June 2020., 2020
Abstract With approximately 3000 marine species, Tunicata represents the most disparate subtaxon of Chordata. Molecular phylogenetic studies support Tunicata as sister taxon to Craniota, rendering it pivotal to understanding craniate evolution. Although successively more molecular data have become available to resolve internal tunicate phylogenetic ...
