A New Species

A new species of Kliopsyllus (Paramesochridae) has been collected with a multicorer from the abyssal Angola Basin in 2000 (on the DIVA-1 cruise, RV Meteor 48/1). Kliopsyllus schminkei sp. n. is the second most abundant Kliopsyllus- species in the Angola Basin and raises the number of valid members of the genus to 33. The new species is placed in the genus Kliopsyllus because of its typical segmentation and the setation of the swimming legs. K. schminkei sp. n. is unique within the genus and can be distinguished from the other species by a large apical pore on the P5 baseoendopodal lobes of the male, a length:width ratio of the furcal rami of 9 to 10:1 in both sexes, and an exceptional ratio of the length of the furcal rami to the whole body size of one fourth in the female and one fifth in the male. The new species is one of the four deep-sea Kliopsyllus-species described until now.

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.

Holothurians of the family Psychropotidae are widely distributed, but remain least studied deep-sea holothurians. On an expedition in the Western Pacific, six psychropotid specimens were collected by the Jiaolong human operated vehicle (HOV). Through morphological examination, four of them were identified as a new species, Benthodytes jiaolongi sp. nov., which was characterized as having minute papillae, narrow brims, and terminal anus; the ossicles were either rods or primary crosses. The remaining two specimens were identified as Psychropotes verrucicaudatus Xiao, Gong, Kou & Li, 2019, which was first recorded at the Kyushu-Palau Ridge. The phylogenetic analysis confirmed the classification status of B. jiaolongi and P. verrucicaudatus, and indicated a paraphyletic relationship within the genus Benthodytes. The new species clustered with Benthodytes sanguinolenta and was separated from the clade containing the other Benthodytes species.

Holothurians of the family Psychropotidae are widely distributed, but are the least studied deep-sea holothurians. On the expedition of the Western Pacific, four holothurians specimens of the family Psychropotidae were collected by the Jiaolong human operated vehicle (HOV). Through morphological examination, two of them were identified as a new species, Benthodytes jiaolongi sp. nov., which was characterized as having minute papillae, narrow brims, and terminal anus; the ossicles were either rods or absent. The remaining two specimens were identified as Psychropotes verrucicaudatus Xiao, Gong, Kou & Li, 2019, which was firstly recorded at Kyushu-Palau Ridge (KPR). The phylogenetic analysis confirmed the classification status of B. jiaolongi and P. verrucicaudatus, and indicated a paraphyletic relationship within the genus Benthodytes. The new species clustered with Benthodytes sanguinolenta and was separated from the clade of the other Benthodytes species. Furthermore, B. sanguinolenta and B. jiaolongi sp. nov. was found to be different from the other Benthodytes species based on their morphology. Therefore, a revision of the genus Benthodytes is needed to solve its phylogenetic relationship.

Four species of the genus Ceratophysella living on mushrooms are reported from China, including a new species, Ceratophysellaskarzynskii Weiner & Sun, sp. n., which is described from alpine mushrooms. The new species belongs to the Ceratophysella group of species with a dorsal chaetotaxy of type B and differs from the other species in a combination of characters. Ceratophysellaskarzynskiisp. n. is distinguished by its small body size (maximum length 1.09 mm), number of peg-like s-chaetae (30–32) in the ventral sensory file, the trilobed apical vesicle of antennal segment IV, five modified chaetae on dens, and serrated dorsal chaetae. A key to the Chinese species of the genus has been provided.

AbstractThe new species Choreutinula kulla sp. n. is described from dry warm seashore habitats in southern Norway and Sweden. It differs from the other European species of the genus, C. inermis (Tullberg, 1871), by smaller body size, coarser skin granulation, longer maxillary lamellae and less setae on the ventral tube. Also the habitat preferences of the two species are probably different as inermis is usually found in forests, often in bark on live conifers.

Thylakogaster namibiensis sp. nov., a new deep-sea species belonging to the family Haplomunnidae Wilson, 1976 is described from the southeast Atlantic Ocean. The differences of the new species to the other species of the genus Thylakogaster Wilson and Hessler, 1974 are discussed. Main characters distinguishing T. namibiensis sp. nov. from its congeners are the presence of cuticular spines on the lateral margins of the pereonites 1–7, the low number of spines on the pleotelson, and the number of five terminal flagellar articles bearing aesthetascs on the antenna 1 of the copulatory male. The new species, T. namibiensis, is the first member of this genus found in the southeast Atlantic Ocean and at a depth of 5415 m, it is also the deepest which a member of the genus has ever been found.

An unfamiliar gastropod was collected from a deep-sea whale carcass at the base of the São Paulo Ridge in the Southwest Atlantic by the manned research submersible Shinkai 6500, and is here described as a new species of the abyssochrysoidean genus Rubyspira, R. brasiliensis sp. nov., following morphological and molecular phylogenetic examinations. There are only two other known species in the genus, which occur together in the Monterey Submarine Canyon off California. The present new species was shown by the molecular analysis to be closer to one of the Californian species than the other. It was found aggregated on and around a whale carcass at a depth of 4204 m, which represents the deepest record of whale- fall ecosystems ever discovered.

Cymbopleura huohuaensis sp. nov. is identified as a new species and described from stone surfaces in Huohua Lake, Sichuan Province, China. A detailed morphological description of the new species is presented, based on light and scanning electron microscopy. Cymbopleura huohuaensis sp. nov. has the features that assign it to the genus Cymbopleura, including the raphe with dorsally deflected terminal fissures and ventrally curved central raphe ends, punctate-lineate striae, and the absence of apical pore fields and stigmata. There are five features that easily distinguish the new species from the other similar taxa within the genus: 1) linear-lanceolate central area, 2) mostly slit-like, partly T-shaped, V-shaped or irregularly-shaped areolae, 3) strongly reverse-lateral raphe, 4) slightly truncate to obtusely rounded ends and 5) the highest density of areolae (30–50 in 10 μm). Among the currently described species of Cymbopleura, the new species is in general most similar to C. subaequalis var. pertruncata in valve shape and possessing a reverse-lateral raphe, but is easily distinguished from that taxon by the size and shape of valve, shape of central area, and the degree of asymmetry about the apical axis and its notable lack of an intermissio. This species might be better placed in the C. austriaca group due to its lack of an intermissio. These findings increase our understanding the morphology and distribution of the genus Cymbopleura in China.

We describe a new species of whiptail lizard genus Ameivula from Planalto dos Gerais, a sandstone plateau that extends along the Cerrado region in the states of Bahia, Tocantins, Piauí, and Minas Gerais, in Brazil. The new species is the third recognized species of the A. ocellifera group registered for the Cerrado. Quantitative analyses of morphometric characters showed that Caatinga species are distinguished from their Cerrado congeners on basis of body size and shape. A discriminant analysis upon meristic characters showed that the new species can be clearly distinguished from the other two Cerrado species A. mumbuca and A. jalapensis, also the morphology of the finger lamellae, and clutch size distinguish these species.

A New Species

Snakes in the Australo-Papuan elapid genus Oxyuranus are considered to be the most venomous species in the world. A recent expedition to the central ranges of Western Australia discovered a third species, which is described here from the only known specimen. Molecular genetic analyses using mitochondrial nucleotide sequences places the new species as the sister lineage of the two described Oxyuranus species, with all three species united by a long branch that also separates them from the nearest of the brown snakes species (Pseudonaja) to which the taipans are close relatives. Morphologically, the new species shares with the other Oxyuranus an undivided anal scale, high midbody scale row (21) and ventral scale (250) counts, but differs in having a single primary temporal scale and fewer lower labials (six). Maximum body size and venom potency are unknown. The discovery of a third species of taipan in the remote central ranges of Australia underlines the paucity of collecting from this region.
