Type locality. Mazatlán , Mexico .

Habitat and distribution. Mexican Pacific and Galápagos Islands; 1–21 m.

Description. Thinly encrusting sponge, 5–10 mm thick, with a finely punctate surface. Inflated asterose aquiferous drainage canals are visible all over the surface in life, and are obvious in the preserved specimen ( Fig. 24C View FIGURE 24 ). Numerous membranous oscules, 2–4 mm in diameter, are scattered over the surface, raised slightly on volcano shaped turrets. Colour in life is bright orange, interior is mustard yellow, colour in ethanol is beige ( Fig. 24A –B View FIGURE 24 ). Texture is compressible, friable.

Skeleton. Brushes of tylotes are present in the ectosome. The choanosome is a loose plumo-reticulation of styles and onychaetes ( Fig. 24D View FIGURE 24 ).

Spicules. Megascleres —Tylotes, with microspined heads; 175 (119–207) × 3 (2–5) µm (n = 60) ( Fig. 24F–G View FIGURE 24 ). Styles, smooth, sharply curved near the proximal end; 185 (160–215) × 6 (3–10) µm (n = 60) ( Fig. 24E View FIGURE 24 ). Microscleres —Onychaetes; 137 (107–198) µm (n = 60) ( Fig. 24H–I View FIGURE 24 ).

Remarks. Specimens of T. (T.) tropicalis collected from the Galápagos Islands correspond well with the morphology and spicule sizes of the original description of the species (tylotes 150–210 µm; styles 150–215 µm; onychaetes 90–180 µm) collected from the Mexican Pacific ( Aguilar-Camacho et al. 2018). This is the first record of T. (T.) tropicalis from the Galápagos Islands.

One species of Tedania has been previously recorded from the Galápagos Islands: Tedania (Tedania) galapagensis Desqueyroux-Faúndez & Van Soest, 1996 . That species has slightly longer styles and tylotes than our specimens, and two size classes of onychaetes.
