Two new species of Sympagella (Porifera: Hexactinellida: Rossellidae) collected from the Clarion-Clipperton Zone, East Pacific

Two new Hexactinellida species from the Clarion-Clipperton Zone (CCZ) in the East Pacific Ocean are described. They are the first described representatives of the genus Sympagella in this region. The new sponges were collected in 2013 during the ABYSSLINE Project´s first cruise, AB01, on board the RV Melville. The CCZ is known for its polymetallic nodules but megafaunal biodiversity is still poorly understood. Our findings suggest that the poriferan fauna of the eastern CCZ is both species rich and inadequately known, and that substantially more sampling and taxonomic studies of the CCZ sponge fauna are required to establish a megafaunal biogeography and evaluate potential extinction risks resulting from polymetallic-nodule mining.

This paper focuses on Aka species boring coral of the East Pacific Ocean and the Caribbean Sea (Mexico). The new species Aka cryptica sp. nov. is described from Mexican Pacific coral reefs, which constitutes the first time that a species of the genus Aka is reported from the East Pacific Ocean. The new species lives cryptically boring coral species of the genus Pocillopora. It is characterized by the small size of their papillae (from 1 to 4.5 mm high and from 0.8 to 1.8 mm in diameter), and oxeas (from 67 to 120 μm), and their exposed parts blend in well with background colours which tend to be overlooked during benthic marine surveys. In addition, Aka coralliphaga and Aka brevitubulata from Mexican Caribbean coral reefs are redescribed. The latter species is reported for the first time in Mexico.

Twenty sponge species (totalling 190 individuals) were collected during the 1938, 1994 and 2004/5 expeditions to the remote island of Clipperton in the East Pacific Ocean. Seven species are widespread Indo-Pacific sponges; nine species comprise sponges new to science; four species were represented only by small thin patches insufficient for proper characterization and could be only determined to genus. The new species may not be necessarily endemic to the island, as several show similarities with species described from elsewhere in the East and West Pacific. Four species: Tethya sarai Desqueyroux-Faúndez & Van Soest (1997), Callyspongia (Callyspongia) roosevelti n.sp., Spongia (Spongia) sweeti (Kirkpatrick, 1900) and Suberea etiennei n.sp. were found commonly occurring in localities around the island in depths between 10 and 55 m, growing on dead corals, under overhangs and rubble stones. The remaining sponges were either rare or were thinly encrusting on coral fragments. The latter may be more abundant than appears from the present study as they are probably not easily observed. The sponge fauna of Clipperton Island shows strongest affinities with the Central and West Pacific regions and only two or three species are shared with the East Pacific region.

This study describes a new genus and two new species of Tanaidacea that were collected from the Singaporean exploratory area (OMS) of the polymetallic nodule fields in the eastern end of the Clarion-Clipperton Fracture Zone, Pacific Ocean. The descriptions are based on material collected during the research cruise ABYSSLINE II, which was conducted in the year 2015, covering abyssal depths of 4041–4227 m. These new species are paratanaoideans belonging to the genera Unispinosus n. gen. and Portaratrum Guerrero-Kommritz, 2003 of the family incertae sedis.
