Cubadeutella cavernicola, a new genus and species of Caprellidae (Crustacea: Amphipoda) from Cuba

Abstract

Cubadeutella cavernicola new genus, new species, is described based on specimens collected from a cave of southern Cuba, Caribbean Sea. Cubadeutella new genus is close to Deutella, but presents a higher number of plesiomorphic characters: the number of articles in antenna 1 is higher in Cubadeutella (20-22) than in Deutella (7-14); the flagellum of antenna 2 in Cubadeutella is 4 -articulate while it is 2-articulate in Deutella and the pereopods 3 and 4 are 4-articulate in Cubadeutella and 1 or 2-articulate in Deutella. Cubadeutella, together with Triantella and Protellina are the only genera in the Caprellinae with the flagellum of antennae 2 more than 2-articulate, and the presence of 4-articulate pereopod 3 and 4 is unique in the Caprellidae.

Deep associations: the symbiotic relationships between amphipods and large invertebrates from bathyal of the Sea of Okhotsk

“…Cyproideid amphipods most often recorded as symbionts of marine sponges (Ortiz et al, 2000); in contrast, stenothoid amphipods are mostly associated with coelenterate hosts (see above). Associations of stenothoid amphipods with sponges are quite rare (e.g., Pearse, 1934;Vader, 1984b;Padua et al, 2013), especially in the North Pacific, e.g.…”

Low‐frequency storminess signal at Bermuda linked to cooling events in the North Atlantic region

“…Here we present a late Holocene storminess and climate record from Bermuda based on costratigraphic signals of terrestrial erosion and oxygen isotopic ratios of benthic foraminifera (δ 18 O c ) archived in Walsingham Cavern, a Bermudian submarine cave. Submarine cave environments exhibit a global distribution across Atlantic [ Rasmussen and Brett , ; Ohtsuka et al ., ; Ortiz et al ., ], Pacific [ Ohtsuka et al ., ; Luter et al ., ; Kano and Kase , ], and Mediterranean [ Zabala et al ., ; Airoldi and Cinelli , ; Corriero et al ., ; Surić et al ., ] coastal carbonate landscapes, and their submerged speleothems have been used in sea level research for decades [ Spalding and Matthews , ; Richards et al ., ; Dutton et al ., ; Surić et al ., ].…”
