Abstract Nothobomolochus triceros (Bassett-Smith, 1898), based on specimens recovered from the original host Pampus argenteus (Euphrasen, 1788) in Japan, are redescribed, and the male, both sexes of copepodids V and IV, and sex undetermined copepodids III and II of the species are described for the first time. The maxilliped is sexually dimorphic only in the adult in Bomolochidae, on the other hand, the rostral plate, antennule, and legs 1, 4, and 5 are sexually dimorphic in Nothobomolochus throughout the adult and copepodids V-IV. Sex is as yet undetermined in copepodids III and II in the genus.

Abstract Triceracolax pagri Izawa, 2021 is redescribed on the basis of specimens of both sexes recovered from the bucco-branchial cavity of the original host, Pagrus major (Temminck & Schlegel, 1843). Both sexes of copepodid IV and the male copepodid III, collected together with the adults, are described for the first time, and sexually dimorphic features in late copepodid stages are discussed.

The male and copepodid V female of O. leptoscari, and the male and copepodid V male of P. sphyraenae are described for the first time for the respective species. A description performed in Izawa (2020, 2021) that the maxilliped of the female bears a dorsal process in Orbitacolax and Paraorbitacolax spp., was wrong and is herein corrected.

For the first time in the rhinological practice the methods of evaluation of the functional state of tissues of nasal cavity that were based on registration of their electrical features-electrical resistance (impedance) and potencial were worked out. In the comparative aspect there were researched the active and the passive electrical features of the tissues of nasal cavity which healthy people and those whose disease is acute sinusitis, have. For the first time the dynamic of electrical features was studied and the most informative electrical rates for the initial diagnostic of acute sinusitis and for evaluation of the effectiveness of appointed treatment were revealed. As a result of researches a new way of noninvasive diagnostic of inflammatory diseases of paranasal sinus was worked out, approved and inserted in practice. (Patent № 2157094, 10.10.2000 «The way of diagnostic of inflammatory diseases of paranasal sinus»). The suggested way is simple, reliable; it has high credibility value of revealing the pathologies of paranasal sinus and evaluation of its dynamic. This method may be recommended for the wide usage in hospitals and clinics for diagnostic of acute sinusitis and evaluation of effectiveness of treatment.

Silver Pomfret

Silver pomfret, Pampus argenteus, is a fish species from coastal waters. Despite its high commercial value, this edible fish has not been sequenced. Hence, its genetic and genomic studies have been limited. We report the first draft genome sequence of the silver pomfret obtained using a Next Generation Sequencing (NGS) technology. We assembled 38.7 Gb of nucleotides into scaffolds of 350 Mb with N50 of about 1.5 kb, using high quality paired end reads. These scaffolds represent 63.7% of the estimated silver pomfret genome length. The newly sequenced and assembled genome has 11.06% repetitive DNA regions, and this percentage is comparable to that of the tilapia genome. The genome analysis predicted 16 322 genes. About 91% of these genes showed homology with known proteins. Many gene clusters were annotated to protein and fatty-acid metabolism pathways that may be important in the context of the meat texture and immune system developmental processes. The reference genome can pave the way for the identification of many other genomic features that could improve breeding and population-management strategies, and it can also help characterize the genetic diversity of P. argenteus.
