Type locality: Peninsula Mejillones , Antofagasta, Chile .
Colour: White in life and light beige in ethanol.
Description: Sponge varying from thin to thick encrusting or massive (1.5 × 1.0 × 0.2 cm) ( Fig. 4A–C View Figure 4 ). Consistency is compressible. Cormus is formed by irregular and tightly anastomosed tubes (0.3−0.5 mm). Watercollecting tubes are present. Granular cells were not observed. Aquiferous system is asconoid.
Skeleton: Without any special organization and composed of two size categories of triactines ( Fig. 4D View Figure 4 ).
Spicules ( Table 4):
1. Triactines I (large): Regular (equiangular and equiradiate). Actines are conical, straight, or slightly undulated with blunt tips ( Fig. 4E View Figure 4 ).
2. Triactines II (small): Regular (equiangular and equiradiate). Actines are conical, straight, with blunt or sharp tips ( Fig. 4F View Figure 4 ).
Reproduction: Buds were observed at the surface of the specimen MNRJ 13148 in December 2008 and several oocytes were observed inside tubes of the specimen MNRJ 11282 in September 2007.
Ecology: Lives in habitats with moderate to high amounts of sediment, predominantly underneath boulders, protected from sunlight. Some individuals were found growing on gastropod shells and others were near polychaete reefs. Ascidians, brachiopods ( Discinisca lamellosa ), bryozoans, hydroids, and polychaetes (e.g. Phragmatopoma sp. and serpulids) were observed near C. antofagastensis . Demosponges (aff. Halichondriidae ) and other calcareans ( Leucosolenia sp. and Grantia sp. ) were also present. Individuals collected in the intertidal zone were found near barnacles and chitons. Microcrustaceans with eggs and small ophiuroids were found associated with specimen MNRJ 13125. Known bathymetric distribution extends from the intertidal to 10 m depth.
Geographical distribution: North coast of Chile (23°S) and along the Peruvian coast (from 5°, 9°, 12°, 13°, and 15°S ( Fig. 4G View Figure 4 ).
Remarks: Clathrina antofagastensis was originally described from and considered provisionally endemic to the north coast of Chile. Its known distribution has now been extended to the north, along the Peruvian littoral. The presence of water-collecting tubes was not observed in the type material; therefore, it was not mentioned in the original description ( Azevedo et al., 2009). The in vivo photos taken of the Peruvian samples allowed verification of the presence of this structure. In order to confirm the identification, a DNA sequence of the holotype was included in our tree, together with three Peruvian specimens morphologically similar to C. antofagastensis . These specimens grouped with the holotype of C. antofagastensis with 100% bootstrap support and only 0.5% divergence. In the present work, C. antofagastensis was the most abundant species, with the largest geographical extension, found in nine localities along the Peruvian coast.
