A New Species

A new species of eolepadid stalked barnacle, Vulcanolepas fijiensis sp. nov., was collected from a hydrothermal vent in the North Fiji Basin, Southwestern Pacific Ocean, at a depth of 1988 m. Based on morphological characteristics, this new species was distinguished from its relatives, V. osheai Buckeridge, 2000, V. parensis Southward, 2005, V. scotiaensis Buckeridge, Linse & Jackson, 2013, and V. buckeridgei Chan & Chang, 2018. Based on morphological characteristics, Vulcanolepas species are divided mainly into two groups by the size of the first mandibular tooth; the first group has a large mandibular first tooth (V. parensis, V. scotiaensis, and V. fijiensis sp. nov., the second a small mandibular first tooth (V. osheai and V. buckeridgei). The new species can be easily distinguished from V. parensis and V. scotiaensis by the length ratio of antenniform segments to robust segments of the rami of cirrus I. Vulcanolepas fijiensis sp. nov. also differs from V. parensis by the length ratio of the penis and cirrus VI (1/10 vs 1/4), and the extension the carinal apex to the tergum (extended vs not extended). Additionally, the sequence divergence of the cytochrome c oxidase 1 gene between V. fijiensis sp. nov. and the other neolepadid species (except V. parensis from its original locations) ranged from 4.2% to 14.0%. In a neighbor-joining tree, V. fijiensis sp. nov. formed an independent branch. These results infer that V. fijiensis sp. nov. is a new species, distinct from the other known neolepadids.

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.

A New Species

A new species of kamakid amphipod, Ledoyerella kunensis sp. nov., is described from waters off Namibia and Angola. This is the first record of this genus in the Atlantic. The taxon is fully described and figured and is compared with the other known species of the genus occurring in waters of the Indian and Pacific Ocean.

A New Species

A new species of Mysidium from the eastern tropical Pacific, Mexico, is described, representing the second species of this genus described for the Pacific Ocean and the eighth species reported worldwide. Mysidium pumae sp. nov. is distinguished from the other species of the genus by several characters including: the lanceolate appendix masculina, 3× as long as wide, tapering distally, with a distal tuft of 16 setae and an inner proximal tuft of more than 30 setae, the male pleopod 4 with endopod bearing 3 setae, the exopod with 4 articles, the modified seta from article 3 of the exopod bifid, telson 2.3× as long as wide, distally concave. A table with the main differences among all the known species in the genus is provided.

A New Species

A new species of Ophlitaspongia (Porifera: Microcionidae) from wave-exposed sublittoral rock in the north-east Atlantic is described and compared to the two other species recorded from the genus in the north-east Atlantic. The species known as Ophlitaspongia seriata is considered to be a junior synonym of Halichondria panicea. Consequently, the name O. papilla has been reinstated. The other recorded species O. basifixa, is from deep water. Ophlitaspongia basifixa has characters which differentiate it from Ophlitaspongia sp. nov. The genus Ophlitaspongia has been separated from related genera and reinstated for species in the North Atlantic.

A new species of siphonostomatoid copepod is described from a hydrothermal vent in the Tofua Arc of the southwestern Pacific at a depth of 1018 m. Chasmatopontius inflatus sp. nov. (Copepoda, Siphonostomatoida, Dirivultidae) is defined and illustrated from specimens isolated from washings of invertebrates including gastropods, bivalves, and crustaceans collected from a hydrothermal vent field. A brief description of its habitat is presented. This new species can be distinguished from C. thescalus, the only known congener, by the greatly expanded mediodistal seta of the caudal ramus in the female, the three-segmented endopod of the female maxilliped, the smaller female body, not exceeding 0.9 mm in length, and the unique shape of the female genital double-somite.

Prunus Grayana

Prunus grayana (subg. Padus) was found to serve as the uredinial-telial host of two distinct Tranzschelia species in Japan. Tranzschelia pruni-spinosae has been known to occur on P. grayana, and the other species was previously overlooked. The latter fungus was experimentally proven to form its spermogonial and aecial stages on Hepatica nobilis var. japonica f. variegata and f. magna. The fungus was similar in morphology and host relationships to Tranzschelia arthurii, whose spermogonial and aecial stages occur on H. nobilis var. acuta and uredinial and telial stages on Prunus serotina and Prunus virginiana (subg. Padus) and Prunus americana (subg. Prunophora) in North America. However, the spores at all stages in the life cycle of the Japanese fungus were significantly smaller than those of the North American fungus. Because of this, a new species, Tranzschelia asiatica, was proposed for the geographically separated fungus. This species is expected to occur in East Asia outside of Japan, but this is not yet confirmed. Key words: rust fungus, Uredinales, Rosaceae, Prunus, Ranunculaceae, Hepatica.
