| From June till December 1987 an inventory of the excavating sponges of the Santa Marta area, Colombian Caribbean, was made by scuba diving to depths not exceeding 18 m. Sixteen species were recorded and compared morphologically, using spicule sizes, papillae shapes, and excavation characteristics. Four littleknown species are fully described and illustrated by submarine color photographs in situ. One appears to be a new species: Axinyssa flavolivescens, belonging to a genus not known to excavate so far. The other three species could not be identified with certainty: Aka äff. xamaycaensis, Aka aff. brevitubulata, and Cliona aff. flavifodina. A key to the excavating sponges of the area studied is provided. |

| Mycale escarlatei n.sp. is described from the coasts of Bahia and Rio de Janeiro in Brazil and from the Santa Marta area in Colombia. It belongs to the subgenus Aegogropila and is distinguished from other congeners in the area, by slender anisochelae-II and possession of micracanthoxeas. Mycale unguifera n.sp. is found in the Islas del Rosario and Santa Marta area in Colombia. It belongs to the subgenus Grapelia and is distinguished within this taxon, by its large and abundant sigmas. The specimen described by Carter (1886) as Pseudoesperia enigmatica, is here proposed as neotype of Grapelia australis. Furthermore, we provide a phylogenetic discussion of centrally-thickened, centrotylote-like toxas, micracanthoxeas, absence of an ectosomal skeleton and... |
