A New Species

Specimens previously identified asBathyconchoecia paululasensu Yin & Chen, 1991 andBathyconchoecia galeritasensu Yin & Chen, 1991, together with two similar specimens, are reclassified as a new species,Bathyconchoecia incisasp. nov., which we describe and illustrate in detail here. The present species is similar toBathyconchoecia sagittariusandBathyconchoecia kornickeriin having a shallow notch on the posterodorsal corner of the carapace, but can be easily distinguished from these species by the structure of the posterior margin of the carapace and the striated sculpturing on the surface of the valves. The specimens on which this new classification was based were collected at shallow depths (<125 m) off the east coast of Hainan Island, in the northern South China Sea and in the Zengmu (James) Shoal and adjacent areas in the southern South China Sea.B. incisais likely to be a shallow-water species or has a wide bathymetric range.

Spongicoloides zhoui sp. nov. (Crustacea: Decapoda: Spongicolidae), a species of deep-sea hexactinellid sponge-associated shrimp, is described based on specimens collected from the Zhenbei Seamount in the South China Sea. The new species is morphologically most similar to the Western Pacific congeneric species Spongicoloides iheyaensis Saito, Tsuchida & Yamamoto, 2006 in that the ischium of the third pereiopod is unarmed and the fixed finger of the third pereiopod is armed with small teeth on the distoventral margin. However, S. zhoui sp. nov. can be distinguished from S. iheyaensis in that its female antennal basicerite has three large spines on the distolateral margin. Molecular analyses based on nuclear histone H3, and mitochondrial cytochrome c oxidase subunit I (COI), 12S ribosomal RNA (rRNA), and 16S rRNA gene fragments confirmed the placement of S. zhoui sp. nov. within a clade of Spongicoloides/Spongiocaris species, and their sequence divergences were large enough to justify the recognition of this new species.

Near-surface wind data are particularly important for Hainan Island and the South China Sea, and there is a wide range of wind data sources. A detailed understanding of the reliability of these datasets can help us to carry out related research. In this study, the hourly near-surface wind data from the High-Resolution China Meteorological Administration (CMA) Land Data Assimilation System (HRCLDAS) and the fifth-generation ECMWF atmospheric reanalysis data (ERA5) were evaluated by comparison with the ground automatic meteorological observation data for Hainan Island and the South China Sea. The results are as follows: (1) the HRCLDAS and ERA5 near-surface wind data trend was basically the same as the observation data trend, but there was a smaller bias, smaller root-mean-square errors, and higher correlation coefficients between the near-surface wind data from HRCLDAS and the observations; (2) the quality of HRCLDAS and ERA5 near-surface wind data was better over the islands of the South China Sea than over Hainan Island land. However, over the coastal areas of Hainan Island and island stations near Sansha, the quality of the HRCLDAS near-surface wind data was better than that of ERA5; (3) the quality of HRCLDAS near-surface wind data was better than that of ERA5 over different types of landforms. The deviation of ERA5 and HRCLDAS wind speed was the largest along the coast, and the quality of the ERA5 wind direction data was poorest over the mountains, whereas that of HRCLDAS was poorest over hilly areas; (4) the accuracy of HRCLDAS at all wind levels was higher than that of ERA5. ERA5 significantly overestimated low-grade winds and underestimated high-grade winds. The accuracy of HRCLDAS wind ratings over the islands of the South China Sea was significantly higher than that over Hainan Island land, especially for the higher wind ratings; and (5) in the typhoon process, the simulation of wind by HRCLDAS was closer to the observations, and its simulation of higher wind speeds was more accurate than the ERA5 simulations.
