“…It is likely that such differences are attributable to specific distinctness. There are a few discrepancies between the descriptions of Arndt (1927) and Boury-Esnault (1973), as Arndt denies the presence of spherasters in his specimens, whereas Boury-Esnault does not mention the presence of microspherasters. The specimens of Arndt were reexamined as they are in the collections of the Zoölogisch Museum of the University of Amsterdam (ZMA Por.…”

“…Placospongia species frequently have tiny (2-3 μm diameter) spherasters lodged in the spaces among the selenasters at the surface. In Placospongia melobesioides Gray (1867a) from Borneo, P. melobesioides sensu Arndt (1927) from Curaçao, P. intermedia Sollas (1888) from the Caribbean end of the Panama Canal, and P. cristata Boury-Esnault (1973) from Brazil, a complement of medium-sized spherasters occurs in the choanosome, looking surprisingly similar to golf balls in SEM images. In Placospongia decorticans (Hanitsch, 1895), spherasters of 16 μm diameter apparently form an extra surface armour on the outside of the layer of selenasters, which could indicate that the surface structure in P. antillensis n. g., n. sp.…”

“…Placospongia melobesioides Gray (1867a) specimens, recorded from the Central West Atlantic originated from Florida, Curaçao and Campeche (Schmidt, 1870;Arndt, 1927;de Laubenfels, 1936a;González-Farías, 1989), may be attributable to a separate regional species, P. cristata Boury-Esnault (1973) originally described from Brazil. Rützler (2002a) suggested this to be a synonym of P. melobesioides, but apart from the large geographic separation of the original locality (Borneo) and the Central West Atlantic, there is also a consistent difference in the upper size of the tylostyles (up to 1200 μm in the type specimen against up to 900 μm in the Central West Atlantic material identified as P. melobesioides and P. cristata).…”

“…In summary the status of records of placospongiids from the Central West Atlantic is as follows: (1) Placospongia carinata sensu Little (1963), Hechtel (1976), Coelho & Mello-Leitão (1978), Pulitzer-Finali (1986) (including citation of Lehnert & van Soest, 1998) , Rua et al (2006), and unpublished specimens from the ZMA collection mentioned above = Placospongia sp. 1 (not: P. carinata (Bowerbank, 1858) (2) Placospongia melobesioides sensu Schmidt (1870), Arndt (1927), de Laubenfels (1936a) Scott & Barnes (2005) performed sequence analysis of a world-wide set of Placospongia specimens, not further identified to species. Their conclusions were that more genetic differentiation is found than would be expected if there were only two or three cosmopolitan 'species'.…”

Thirteen new species of sponges are described from coral reefs of the Netherlands Antilles and the Colombian Caribbean. Species were collected during quantitative investigations of reef sponges performed by students of the University of Amsterdam in the period between 1984 and 1991. Most of the reported specimens were taken from undersides of coral rubble, crevices or reef caves (sciophilous habitats) and without exception are small encrusting or fistular sponges. The material reported in this paper includes a new genus and species of Placospongiidae, Placospherastra antillensis n. g. n. sp. , the first Caribbean representatives of the genera Triptolemma (Pachastrellidae) and Megaciella (Acarnidae), viz. Triptolemma endolithicum n. sp. and Megaciella incrustans n. sp., a new species of Timeidae, Timea curacaoensis n. sp., a new species of Microcionidae with peculiar colloscleres, Clathria (Thalysias) collosclera n. sp., two new species of Chondropsidae, viz. Batzella fusca n. sp., and Strongylacidon unguiferum n. sp., three new species of Coelosphaeridae, viz. Forcepia (Forcepia) minima n. sp., Forcepia (Forcepia) fistulosa n. sp., and Forcepia (Leptolabis) microlabis n. sp., a new species of Crellidae, Crella (Grayella) beglingerae n. sp., a new species of Hymedesmiidae, Hymedesmia (Hymedesmia) bonairensis n. sp., and a new species of Mycalidae, Mycale (Paresperella) vitellina n. sp. Most species are represented by only small fragments removed from the substrate by scalpel or diving knife, leaving little and often crumbled preserved type material. This study is intended to demonstrate that the small crusts dominating easily accessible shallow water coral rubble habitats in the Caribbean remain understudied.

Knowledge about the sponge fauna from the Mexican Pacific Ocean has increased substantially in recent years, but most of these modern taxonomic studies have been focused on hadromerids. The aim of this study was to contribute to the knowledge of the order Poecilosclerida. At present, seven species of Mycale have been described or recorded from the Pacific coast of Mexico, but only three of them are considered valid: M. contax, M. cecilia and M. aff. magnirhaphidifera. After a revision of the material collected during the last eight years throughout the East Pacific coast of Mexico, along with the type material, and the literature available, eight species of Mycale are considered valid, three of them; M. magnitoxa sp. nov., M. dickinsoni sp. nov., and M. ramulosa sp. nov., are proposed as new to science. In addition, M. adhaerens is reported for the first time from the Mexican Pacific Ocean. Another Mycale-species that was identified was M. psila, which constitutes its seconLamberd record for the Mexican Pacific Ocean. The systematic, distribution and detailed species descriptions are based on newly collected material and previous descriptions from the literature.
