Aguilar-Camacho, J. M., Carballo, J. L. & Cruz-Barraza, J. A. (2018) Tedania (Porifera: Demospongiae: Poecilosclerida) from the Mexican Pacific with the description of two new species. Journal of Natural History, 52, 1311-1332.
Two new species of Tedania (Porifera: Demospongiae: Poecilosclerida) are described from the Mexican Pacific. Tedania (Tedania) tropicalis sp. nov. is an encrusting to massive sponge having ectosomal tylotes with microspined heads, choanosomal styles and onychaetes. Tedania (Tedania) fulvum sp. nov. is a thinly encrusting sponge having ectosomal tylotes with smooth heads, choanosomal styles and onychaetes. Tables for all the Tedania (subgenera Tedania and Tedaniopsis) and Trachytedania species described worldwide are included. We suggest that species of Tedania and Trachytedania bearing ectosomal diactinal spicules (excluding Tedania (Stylotedania)) can be separated in two main groups: those having choanosomal monactinal spicules and those with choanosomal diactinal spicules.
