We found four species of oribatid mites belonging to family Oppiidae from Babeldaob Island of Palau Republic, which is an island country located in the western Pacific Ocean. Two new species, Anomaloppia babeldaobensis sp. nov. and Oxyoppia palauensis sp. nov. are described from litter and soil in a secondary forest of Palau, and supplementary descriptions of two hitherto known species, Arcoppia corniculifera (Mahunka 1978) and Arcoppia hammerae Rodríguez & Subías, 1984 are provided, which are reported for the first time from the Oceania region. Following the descriptions and comparisons, aspects of the taxonomy, distribution and habitat ecology of studied species are discussed.

A new genus and species of glass sponge, belonging to the family Pheronematidae, is described from a single specimen collected from a seamount near Yap Trench in the western Pacific Ocean. Pheronemoides fungosus gen. et sp. nov. is described based on external morphology. In Pheronemoides gen. nov. the basalia are grouped in a broad semicircular tuft attaching to the dermal surface, and marginalia are located on the boundary between the atrial and dermal surfaces. Given the positions of the basalia and the marginalia, we recognize Pheronemoides as a transitional genus between Pheronema and Sericolophus. We also used a partial sequence of the 16S rDNA gene to confirm the validity of the new species designation.

Three new species of pennellid copepods are described based on specimens taken from gobiid fishes. Creopelates nohmijimensis n. sp. was found on Priolepis boreus (Snyder) in the Seto Inland Sea, Japan. This new species is distinguishable from its sole congener, C. floridus Shiino, 1958, by the presence of four finely digitate lobes on the cephalothorax and in having four pairs of legs occurring closely together at the anterior end of the neck. Two new species of Cardiodectes, C. asper n. sp. and C. bertrandi n. sp., were collected, from Trimma grammistes (Tomiyama) off IzuOshima Island, Japan and Eviota sp. off the Loyalty Islands, New Caledonia, respectively. Cardiodectes asper n. sp. is distinguished from its 12 congeners by the absence of the abdomen, byhaving a trunk not longer than twice of its width, a cephalothorax with three pairs of lateral lobes, and a pair of neck lobes carrying leg 3 on the posterior surface of their bases. Cardiodectes bertrandi n. sp. is identifiable by the presence of two pairs of lateral cephalothoracic lobes, with smaller anterior pairs; a trunk twice as long as wide; and leg 3 located at the posterior end of the anterior neck lobe.

The family Trachipteridae—the Ribbonfishes, Dealfishes, and their relatives—has a circumglobal distribution, with at least 10 species in three genera (Zu Walters & Fitch 1960, Desmodema Walters & Fitch 1960, and Trachipterus Goüan 1770) that are characterized by elongate, extremely laterally compressed bodies, large eyes, absence of ribs, spines on lateral-line scales, greatly protrusible mouths, and a lack of pelvic fins in adults. They are also known for the drastic morphological changes that occur during ontogeny. Trachipterids are poorly represented in collections due to the fragile nature of their bodies. Most studies of the Trachipteridae have been limited by the numbers, developmental stages, and the completeness of the specimens that were examined. Along with the lack of available material, incomplete and conflicting character information compounds the taxonomic confusion of Trachipteridae. Despite the body of regional revisions that have examined trachipterid taxonomy, none have synthesized a suite of morphological characters across ontogeny. The goals of this paper are to (1) revise the family Trachipteridae, (2) revise the genera Trachipterus, Zu, and Desmodema, including information regarding ontogeny and biogeography, and 3) address the alpha taxonomy of Zu, Desmodema, and Trachipterus from the western Pacific Ocean. We recognize possibly five species of Trachipterus as being present in the western Pacific, as well as two species of both Zu and Desmodema. Despite additions to the specimen base that allows refinement of taxonomy and diagnoses, there are still large knowledge gaps associated with the taxonomic review of Trachipteridae. These reflect incomplete understanding of geographic distribution of taxa which may mask unrecognized taxonomic variability. The genus Trachipterus specifically remains problematic and will require greater detailed global study. Early life history stages remain unknown for several taxa which hinders full interpretation of ontogenetic transitions. Protracted transitions, some of which are clarified here, further confuse stage-based diagnoses and must be considered in future analyses of this family.

The barbeled dragonfish genus Eustomias in Taiwan is reviewed. Five species in three subgenera are recognized, including three new species, a new record, and an unidentified species. Eustomias (Dinematochirus) dendrobium sp. nov. can be distinguished from its congener by its unique barbel structure. Eustomias (Haploclonus) stamen sp. nov. has a unique barbel structure and diagnostic meristic characters. Eustomias (Nominostomias) tritentaculatus sp. nov. has an extremely long barbel and distinct pigmentation, with fin ray counts that are different from most similar species. Eustomias (Nominostomias) perplexus Gibbs, Clarke & Gomon 1983, widespread in the western Pacific Ocean is reported for the first time from Taiwan. Three specimens of Eustomias were only identifiable to subgenus Haploclonus due to their poor condition.
