Only three species of the sponge genus Plakina Schulze have been described from the Mediterranean since 1880, in spite of a large amount of allegedly intraspecific variability in morphological characters. However, recent genetic studies based on electrophoretic techniques have revealed extensive cryptic speciation in north-western Mediterranean Plakina, demonstrating that most of this variation was interspecific rather than intraspecific. We describe in detail the morphology and anatomy of four…

Descriptions of new sponge species and genus, including aspiculate Plakinidae, overturn the Homoscleromorpha classification
TLDR
The need for a detailed re-examination of Homoscleromorpha is indicated using this integrative taxonomic approach and two new species of Plakinidae from submarine caves in the Caribbean Sea are described: Plakina arletensis sp.
Integrative taxonomic description of Plakina kanaky, a new polychromatic sponge species from New Caledonia (Porifera: Homoscleromorpha)
TLDR
The present work demonstrates that integrative taxonomy should be used in order to revise the entire Plakinidae family and especially the non-monophyletic genus Plakina, with the most parsimonious conclusion being to propose a single new species P. kanaky sp.
Taxonomy of Plakina (Porifera: Homoscleromorpha) from Aegean submarine caves, with descriptions of three new species and new characters for the genus
TLDR
Five species of the homoscleromorph genus Plakina are described from submarine caves in the Aegean Sea (Lesvos Island, Greece) with exceptionally stout, annulated lophose spicules with highly variable ramification patterns, including some original types.
Anatomy, cytology and symbiotic bacteria of four Mediterranean species of Plakina Schulze, 1880 (Demospongiae, Homosclerophorida)
TLDR
The internal anatomy, cytology and symbiotic bacteria of four Mediterranean species of the sponge genus Plakina Schulze are investigated under light and transmission electron microscopy in a search for new, taxonomically useful characters.
Molecular Phylogeny Restores the Supra-Generic Subdivision of Homoscleromorph Sponges (Porifera, Homoscleromorpha)
TLDR
This study proposes to restore the pre-1995 subdivision of Homoscleromorpha into two families: Plakinidae Schulze, 1880 for spiculate species and Oscarellidae Lendenfeld, 1887 for aspiculate species that had been rejected after the description of the genus Pseudocorticium.
Taxonomy of family Plakinidae (Porifera: Homoscleromorpha) from eastern Pacific coral reefs, through morphology and cox1 and cob mtDNA data
TLDR
The first time that the standard cox1 ‘barcoding fragment’ has been analysed for the systematics of Plakinidae showed to Plakina as a monophyletic group, which is congruent with the morphological hypothesis.
Integrative taxonomy widens our knowledge of the diversity, distribution and biology of the genus Plakina (Homosclerophorida: Plakinidae)
TLDR
Data of morphology, cytology, microbiology, ecology, reproduction, and mitochondrial cox-1 and cob gene sequences are integrated to resolve a complex of sympatric species of Plakina in South-eastern Brazil to support the delimitation of three species, two of which are new to science.
‘A posteriori’ searching for phenotypic characters to describe new cryptic species of sponges revealed by molecular markers (Dictyonellidae : Scopalina)
TLDR
Three new species of sponge are formally described after careful searching for discriminatory phenotypic characters and are at first sight morphologically similar and inhabit shallow environments with resuspended sediment.
Five new species of Homoscleromorpha (Porifera) from the Caribbean Sea and re-description of Plakina jamaicensis
Five new species of Homoscleromorpha (Porifera) of four genera, Oscarella, Plakortis, Plakina and Corticium, are described from vertical walls of reef caves at depths ranging from 23 to 28 m in the…

TLDR
A collection of 32 specimens of the genus Plakortis from Australia and the Indo-Pacific is here examined and the number of valid species in the genus is raised from 15 to 19.

Genetic evidence for extensive cryptic speciation in the subtidal sponge Plakina trilopha (Porifera:Demospongiae:Homoscleromorpha) from the Western Mediterranean
TLDR
The genetic differences found between the morphotypes indicate that these should not be considered conspecific, and species boundaries were delimited by genetic data, diagnostic morphological characters for each species could be found.
Genetic differentiation between morphotypes of the marine sponge Suberites ficus (Demospongiae: Hadromerida)
TLDR
The genetic differences, indicating reproductive isolation, are strong evidence for separate gene pools and, hence, that they are different species.
Cytological evidence for cryptic speciation in Mediterranean Oscarella species (Porifera, Homoscleromorpha)
TLDR
Three new sponge species without a skeleton, Oscarella viridis, O. microlobata, and O. imperialis, were found in sublittoral caves and on vertical walls along the coast of Provence and reveals an unexpected biodiversity of this genus in the Mediterranean Sea.
Sponges without skeleton: A new Mediterranean genus of Homoscleromorpha (Porifera, Demospongiae)
TLDR
A new genus of aspiculate homoscleromorph, Pseudocorticium, is described along with the new species P. jarrei found in a littoral cave located in the western Mediterranean Sea (France), which differs from Oscarella in its morphology, anatomy, and cytology.
Genetic and cytological divergence between colour morphs of the Mediterranean sponge Oscarella lobularis Schmidt (Porifera, Demospongiae, Oscarellidae)
TLDR
The demosponge Oscarella lobularis has been reported from various localities throughout the world and is considered to be morphologically very variable, and morphs of different colour or texture can be found living sympatrically.
Genetic evidence for cryptic speciation in allopatric populations of two cosmopolitan species of the calcareous sponge genusClathrina
TLDR
It is concluded that, at least for the species studied, and probably for many other species in taxonomically difficult groups, the actual distributions of single species may be far more geographically restricted than is generally assumed.
Biochemical and Morphometric Differences of Two Sympatric Sibling Species of Clathria (Porifera: Demospongiae: Microcionidae) from Northern Australia
TLDR
Two cryptic sympatric species of Clathria were discovered incidentally during an electrophoretic study of 62 poecilosclerid and axinellid species, and the significance of cryptic characters to the existing morphological systematics of Microcionidae is discussed.
Studies on Indian Sponges IV. Additions to the genus Corticium schmidt with notes on the distribution of Corticium candelabrum Schmidt
TLDR
Two species of the genus Corticium Schmidt of the Order Carnosida Carter and family Halinidae de Laubenfels were collected by the author and the first is a new species and the second is reported here from Indian region.
Comparative study of the choanosome of Porifera: 1. The Homoscleromorpha
TLDR
These two families of sponges have the following morphological features in common: flagellated endopinacocytes with short apical microvilli and basal pseudopods; the presence of a very thin and dense sheet of matrix material which limits the mesohyl.
