Material examined

Holotype: 2064-LEB-ICML-UNAM, 24 June 2011, Isla Hermano Sur (Mazatlán, Sinaloa) 8 m (23° 11 ʹ 5 ʺ N, 106°24 ʹ 7 ʺ W). GoogleMaps

Description

Thinly encrusting sponge 1–3 cm long, 2–8 mm thick. Surface smooth. Oscula and ostia not visible. Consistency flexible and elastic. Colour in life yellow; pale in preservation ( Figure 3 View Figure 3 (b)).

Skeleton

Ectosomal tylotes with smooth heads, 130–150 × 2.5–5 μm ( Figure 5 View Figure 5 (b)); choanosomal styles curved or straight, 135–185 × 2.5–5 μm ( Figure 5 View Figure 5 (a)) and onychaetes in variable dimensions: 30–120 × 0.5–1 μm ( Figure 5 View Figure 5 (c), 5(d)). The ectosomal skeleton is a layer of tylotes (15 μm thick). The choanosomal skeleton has a plumose reticulum made of multispicular fibres (15–35 μm thick). The onychaetes are dispersed with no special organization.

Remarks

Tedania (Tedania) fulvum sp. nov. is an encrusting sponge from the Bay of Mazatlan with tylotes bearing smooth heads, straight choanosomal styles and onychaetes. There are four species with these features in the Pacific Ocean. Tedania (Tedania) battershilli Bergquist and Fromont 1988 is a red/orange encrusting sponge described from the Maori Islands

( New Zealand), with tylotes (185–310 × 3–5 μm), styles (215–315 × 4.5–7 μm) and onychaetes in two categories (I, 105–163 μm; II, 33–73 μm). The megascleres are shorter in T. (Tedania) fulvum sp. nov. than in T. (Tedania) battershilli . Tedania (Tedania) purpurescens Bergquist and Fromont 1988 is a purple encrusting sponge described from Poor Knight Island ( New Zealand) with tylotes/politylotes (270–300 × 3–5 μm), styles straight (230–300 × 4–6.5 μm) and onychaetes in two categories (I, 110–133 μm; II, 45–55 μm). The megascleres are longer in T. (Tedania) purpurescens than in T. (Tedania) fulvum sp. nov. Tedania (Tedania) rhoi Sim and Lee 1998 is a pinkish massive or cushion-shaped sponge from Korea. This species has tylotes (230–290 × 4–5 μm), straight styles (270–340 × 8–10 μm) and onychaetes in three categories (I, 160–170 × 1 μm; II, 120–130 × 3 μm; III, 40–50 × 1 μm). The megascleres are shorter in T. (Tedania) fulvum sp. nov. than in T. (Tedania) rhoi . Tedania (Tedania) toxicalis de Laubenfels 1930 is a brownish-red sponge from California with tylotes (200 × 8–14 μm), choanosomal subtylostyles (100–200 × 2–7 μm) and onychaetes (150 μm). The tylotes are longer and thicker in T. (Tedania) toxicalis than in T. (Tedania) fulvum sp. nov.

Etymology
