A New Species

A new species of the rare caridean genus Bresilia Calman, 1896, B. cinctus, is described and illustrated on the basis of a single ovigerous female specimen collected from Sagami Bay, central Japan, at 218–318 m depth. The new species is morphologically most similar to B. rufioculus Komai & Yamada, 2011, known only from shallow water cave of Ie Island (depths 14–17 m), Okinawa Islands, Ryukyu Islands, but many characters, including the proportionally shorter rostrum, the well developed suborbital lobe of the carapace, and the presence of a spiniform seta on the ventral surface of the pereopod 1 palm, immediately distinguish the new species from B. rufioculus. Bresilia cinctus n. sp. is the first species of the genus known from the Japanese main islands. The discovery of the new species led us to reassess the merit of the informal division of Bresilia proposed by Komai & Yamada (2010). An identification key to the ten named species of Bresilia is presented.

A New Species

A new aegisthid copepod, Cerviniopsis reducta sp. nov. is described from the deep sea in Sagami Bay, Japan. The newspecies has superficial resemblance to C. minutiseta Ito, 1983 in the armature formula of swimming legs. However theydiffer from each other in the shape of setae of the swimming legs, the distal margin of operculum, length of caudal rami,and the location of setae on P5 exopod. Also, the male of Neocervinia itoi Lee & Yoo, 1998 is described on the basis ofsamples collected from around the type locality in Sagami Bay, Japan. Sexual dimorphism of N. itoi male can be observedin the fused rostrum, atrophied mouthparts, P5, and P6. The sixth leg is symmetrical and both gonopores are presumablyactive, based on the presence of two spermatophores internally in the genital segment. This paper reports for the first timeon the sexually dimorphic characters in the genus Neocervinia Huys, Mobjerg & Kristensen, 1997, reinstating its generic status with the newly revealed male characters.

A New Species

A new species of slipper lobster of the genus Petrarctus Holthuis, 2002 was discovered from southwestern India during a survey of deep sea crustaceans. The new species closely resembles P. veliger Holthuis, 2002 from the Andaman Sea and western Pacific but differs mainly in the color marking on abdominal somite I, having a relatively lower cardiac tooth but with better developed tubercles on the abdomen, as well as a differently shaped anterior part of the thoracic sternum. Molecular genetic analysis also confirms the distinct taxonomic status of the new species. To fix the identity of the type species of the genus, a neotype of P. rugosus (H. Milne Edwards, 1837) was selected from a recently collected Indian specimen with color and genetic information.

A New Species

A new deep-sea stalked barnacle, Ashinkailepas kermadecensis sp. nov. has been recovered from a cold-water seep at depths of 1165 metres in the vicinity of the Kermadec Ridge to the northeast of the North Island, New Zealand. There are now two species of Ashinkailepas—the other, Ashinkailepas seepiophila Yamaguchi, Newman & Hashimoto, 2004, occurs in deep, cold seeps off central Japan. As there are two species within Ashinkailepas, formal diagnoses are provided for both taxa.
