A New Species

A new species of a stalked ascidian (genus Polycarpa, family Styelidae) is described from living and preserved material. Living specimens of the new and some sympatric species were observed and photographed in situ and specimens of the former were collected by the manned submersible "JAGO" at depths between 200 and 277 m off Sangihe Island between Sulawesi (Indonesia) and the Philippines. Specimens display a number of adaptations known previously from a range of ascidian taxa recorded from deeper waters, including a stalk from the anterior end of the body, the loss of ciliated pharyngeal perforations and wide atrial apertures exposing extensive areas of the branchial sac.

A New Species

Abstract The new species, Paroctopus cthulu sp. nov. Leite, Haimovici, Lima and Lima, was recorded from very shallow coastal waters on sandy/muddy and shelter-poor bottoms with natural and human-origin debris. It is a small octopus, adults are less than 35 mm mantle length (ML) and weigh around 15 g. It has short to medium sized arms, enlarged suckers on the arms of both males and females, large posterior salivary glands (25 %ML), a relatively large beak (9 % ML) and medium to large mature eggs (3.5 to > 9 mm). The characteristics of hatchlings of two brooding females, some of their anatomical features, and in-situ observations of their behaviour are a clue to the life history of it and closely related pygmy octopuses. The Bayesian phylogenetic analysis showed that Paroctopus cthulu sp.nov. specimens grouped in a well-supported clade of Paroctopus species, separate from P.joubini and P. cf mercatoris from the Northwestern Atlantic . The description of this new species, living in a novel habitat of human debris in shallow water off Brazil, offered an opportunity not only to evaluate the relationship among the small octopuses of the western Atlantic, Caribbean and eastern Pacific, but also their adaptation to the Anthropocene period.

A New Species

Munidopsis myojinensis n. sp., herein described and illustrated from Myojin Knoll and Northwest Eifuku Seamount in the Western Pacific, is the tenth species of Munidopsis known to be associated with active hydrothermal vents. It resembles M. starmer Baba & de Saint Laurent, 1992 in general ornamentation and spination of the body but differs in the erectness of the eyespine and form of the telson plates. Information on genetic identification using mitochondrial sequences (COI) is provided. Distributions of the vent associated Munidopsis in the Western Pacific and the habitat of the new species are briefly described.

A New Species

A new species of azooxanthellate solitary Scleractinia, Placotrochides yapensis n. sp., is described from the foot of a seamount near the Yap Trench in the tropical Western Pacific at the water depth of 2,700–2,734 m. The specimens are assigned to the genus Placotrochides Alcock, 1902 on account of possessing a solitary corallum, a trabecular columella and the transverse division resulting in a free anthocyathus with a basal scar. The new species differs from its four congeners by (1) the larger corallum size (greater calicular diameter 15.2–15.7 mm, greater basal scar diameter 9.0–12.2 mm, and height 13.3–17.1 mm), (2) the larger edge angle (20–25°), (3) the arrangement of septa (S1–2>S3>S4), and (4) the number of septa (48). Until now, five species of Placotrochides have been known from deep waters and Placotrochides yapensis n. sp. is the deepest record of the genus.

A New Species

A new labrid fish, Terelabrus zonalis sp. nov., the fourth species of the genus, is described on the basis of two specimens collected from the Philippines. The new species is characterized by 44 longitudinal series scale rows, 42 pored lateral-line scales, 11–12 gill rakers (including rudiments), the main supratemporal sensory canal with 8 branches posteriorly, the area bounded by the main supratemporal and postotic sensory canals (dorsal view) with 3 scale rows, the least distance between the orbit anteroventral margin and interopercle 7.0% of standard length and 18 faint silver vertical bands on the body in preserved specimens. An underwater photograph of T. dewapyle is reported as the first record of the species from the Philippines. A key to species of Terelabrus is provided.

A New Species

A new species of congrid eel, Bathycongrus villosus sp. nov., is described from the Philippines and Vanuatu. It is similar to some of the small-toothed species currently placed in Bathycongrus and to the species of Bassanago. In this paper we compare the new species to Bassanago albescens (Barnard, 1923) and to Bathycongrus parviporus Karmovskaya, 2011, which it most closely resembles. An analysis of 19 characters shows that it agrees with Bat. parviporus in 16 characters and with Bas. albescens in one. In two characters, the three species are all different. We therefore place it in Bathycongrus.

A new species sandperch, Parapercis altipinnis, is described based on the holotype collected from Cebu, the Philippines at 55–65 m by SCUBA. The new species belongs to the P. cylindrica complex and can be distinguished by an extremely high first dorsal fin, the first spine slightly longer than the head; 3 predorsal scales; 42 or 43 lateral-line scales; teeth present on vomer and palatines. The body is reddish dorsally and blackish ventrally, with 5 large brownish saddles alternating with white bands on dorsal surface; scattered dots on top of head, first dorsal fin and dorsal surface; first dorsal fin milky white with 5 black marks on anterior margin; a black broad band below eye; cheek and throat blackish red surrounding by white color; row of 10 short white bars along the lateral side of body axis; row of 9 deep red to blackish bars on lower half of lateral side of body; base of pelvic fin and lower margin of caudal fin blackish; rows of black spots on soft dorsal fin. A key to the species of the complex is provided.

A New Species

Munida diritas sp. nov. is described for the seamounts near Desventuradas Islands, in the intersection of the Salas & Gómez and Nazca Ridges, Chile. Specimens of the new species were collected in the summit (∼200 m depth) of one seamount and observed by ROV at two nearby ones. This species is characterized by the presence of distinct carinae on the thoracic sternites 6 and 7. Furthermore, it is not related with any species from the continental shelf nor the slope of America, while it is closely related to species of Munida from French Polynesia and the West-Pacific Ocean (i.e., M. ommata, M. psylla and M. rufiantennulata). In situ observations indicate that the species lives among the tentacles of ceriantarid anemones and preys on small crustaceans. The discovery of this new species adds to the knowledge of the highly endemic benthic fauna of seamounts of the newly created Nazca-Desventuradas Marine Park, emphasizing the relevance of this area for marine conservation.

A New Species

A new species of Nesolinoceras Ashmead from the Dominican Republic is described and illustrated. A key to the species and a revised and expanded distribution map is presented. This is the third species recognized for the genus, and the first one confirmed to occur in high altitude (1100 m). When compared with the previously known species, a number of unique and shared features emerged, supporting a redefinition of the genus beyond that of Santos (2016): (1) the known inter-specific variability of 48% of the examined characters increased considerably, confirming their diagnostic value at the species-level, and (2) the stability of six features support them as additionally diagnostic for the genus: 22–23 flagellomeres; mesoscutum subcircular, as long as wide; scuto-scutellar carina absent, axillary trough shallow, indistinct on scutellum; subalar ridge wide, somewhat ovoid, not keeled; crossvein 1cu-a arising basad of vein 1M+Cu by about 0.3 its length; and vein 2-M only slightly longer than vein 3-M. Furthermore, two important measurements for the diagnosis of Nesolinoceras now have new, expanded ranges: areolet 1.8–2.6 as long as pterostigma width, and areolet 0.7–1.0 as long as wide. The new taxon is readily recognizable by having the body mostly brown, fully infuscated wings, and the longest ovipositor of the species, among other diagnostic features. A new geographic record and in situ photo are also provided for N. laluzbrillante Santos.
