Abstract
A new species of the genus Cyphocaris Boeck, 1871, is described. The material examined was collected during the “Acoustics along the Brazilian Coast” (Abraços 1) project, by micronektonic trawls at a targeted depth of 525 m, off the Rocas Atoll, Rio Grande do Norte state, Brazil. Cyphocaris boecki sp. nov. can be grouped with the eyed species in the genus but differs from them—except for C. faurei K. H. Barnard, 1916 and C. latirama, Hendrycks & Conlan, 2003—in presenting a dorsally smooth pereonite 1. However, the new species can be distinguished from both by its maxilliped inner plate with two robust apical setae, pereopod 7 basis with weakly produced posterodistal lobe, telson lobes without setae, spines or apical nails, and other characters that are individually discussed among them. The new species can be readily differentiated from C. pedroi Sorrentino, Alves, Johnsson & Senna, 2016, also described from Brazil, by presenting eyes, a rounded lateral cephalic lobe, very elongated antenna 2 almost reaching body length, and pereopod 5 basis, with apically acute spur reaching about two-thirds of the propodus. This is the second record of the genus for Brazilian waters.
Highlights
Mesopelagic and bathypelagic amphipods play an important role in macropelagic communities of all oceans
Cyphocaris boecki sp. nov. is among the species of the genus that possess eyes, as follows: C. ananke, C. anonyx, C. bellona, C. cornuta, C. faurei, C. johnsoni, C. latirama, C. nesoi, C. ohtsukai, C. polaris, C. richardi, C. tartaros, and C. tunicola
The new species is differentiated from all these species by its dorsally smooth pereonite 1, which has no projection
Summary
Mesopelagic and bathypelagic amphipods play an important role in macropelagic communities of all oceans. They are an important food source for fish and marine mammals, and act as carnivorous predators, herbivores, suspension feeders, or necrophages. They are less diverse than benthic amphipods and are less studied [1]. H. Milne Edwards, 1830 [2,3,4,5,6], and families such as Alicellidae Lowry & De Broyer, 2008, Amathillopsidae Pirlot, 1934, Cyphocarididae Lowry & Stoddart, 1997, Eurytheneidae. Cyphocaris pedroi Sorrentino, Alves, Johnsson & Senna, 2016, is reported for this
