“…Although similar setae are occasionally observed in other harpacticoid species (e.g., Enhydrosoma casoae Gómez, 2003 (Cletodidae) [24]; Parepactophanes dubia Noodt, 1958 (Canthocamptidae) [25]; Huntemannia jadensis Poppe, 1882 (Nannopodidae) [26]), they only occur in the Orthopsyllidae Huys, 1990, e.g., ref. [27] in the same form and number as in most Rhizothrichidae. However, the Orthopsyllidae are derived representatives of the Laophontoidea [28], the supposed sister group of the Cletodoidea [20] and must therefore have developed their brush-like setae convergently.…”

During expedition EMB-238 of RV EM BORGESE to the Fehmarn Belt (Baltic Sea, Germany) in 2020, specimens of a new species of the Rhizothrichidae Por (Crustacea, Copepoda, Harpacticoida) were found. Currently, Rhizothrichidae enclose two genera: Rhizothrix Sars and Tryphoema Monard. The assignment of the new species is based on the following commonly derived characters: the formation of a strong spinulose (sub)apical element on the last segment of the female A1, and the formation of a long brush seta on the last exopodal and endopodal segments of the P1. The new species could not be assigned to either Rhizothrix or Tryphoema because it lacks their autapomorphies but presents exclusive derived characters, including the absence of the abexopodal seta on the A2 allobasis, the possession of only one seta on the endopods of P2–P4, and the fusion of the female P5 exopod and baseoendopod. Therefore, it is assigned to a new genus. Besides the species description, its phylogenetic position in the Rhizothrichidae as well as its possible relationship with Rhizothrix and Tryphoema are discussed. Furthermore, the affiliation of the Rhizothrichidae with the Cletodoidea is justified on the basis of 17 apomorphies. A key to the rhizothrichid genera is provided.

“…4 Most water-soluble inorganic metal salts can be separated from the feedstock by normal processes, such as water washing and desalting, but oil-soluble organic calcium compounds cannot be easily removed by these methods. 5 Therefore, some additional processes are needed to remove these compounds. Several techniques have been utilized for the removal of calcium and iron from crude petroleum, such as the hydro-demetallization, 6 the solvent extraction, 7−9 the electrochemical deposition method, 10 and so forth.…”

A novel environmental decalcifying agent was prepared with allylpolyethoxy amino carboxylate (APEAA), hydroxyethyl acrylate (HEA), and maleic anhydride (MA) by means of free-radical polymerization in an aqueous solution. The morphology and structure of the samples were characterized through scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectrometry, and 1 H nuclear magnetic resonance ( 1 H NMR) spectra. The molecular-weight distribution of APEAA–HEA–MA was determined by the gel permeation chromatography method. APEAA–HEA–MA was used as a green decalcifying agent to remove calcium from crude petroleum, and the impact of factors such as monomer ratio, copolymerization time, dosages, and desalination temperature was analyzed. It is found that the decalcification rate of APEAA–HEA–MA could reach to its maximum, and the calcium removal efficiency was approximately 97.88% when the monomer molar ratio of APEAA–HEA–MA was 1:2:5, the reaction time of copolymerization was 2 h, the dosage was 100 ppm, and the desalination temperature was 100 °C. This research work can promote the exploration on facile synthesis of a novel terpolymer and its potential application in refinery desalting processes.
