The occurrences of 13 specimens belonging to 9 species of little known marine fishes in the Northeast Atlantic in 2017 and 2018 are reported. Information about the morphology and new findings of Decapterus tabl and Decapterus macarellus (Carangidae), Kyphosus vaigiensis (Kyphosidae), Remora osteochir (Echeneidae), Antigonia capros (Caproidae), Hyperoglyphe perciformis (Centrolophidae), Halobatrachus didactylus (Batrachoididae), Parapristipoma octolineatum (Haemulidae) and Zu cristatus (Trachypteridae) are reported in different locations, where they are categorized as unusual or rare. Morphometric and meristic parameters confirm the identification to species level of each specimen, also supported by DNA barcoding. Histological examination of reproductive tissue is carried out in four specimens to know the sex and their reproductive stage. All species are known from other areas of the Atlantic Ocean, but these findings are an important contribution to understanding their biology and distribution. These include a new northernmost record of Remora osteochir and Decapterus tabl in the eastern Atlantic and the first records of Antigonia capros, Hyperoglyphe perciformis, Halobatrachus didactylus and Parapristipoma octolineatum from Galician waters.

The article is devoted to the study of new representatives of the genus Kerpia Naugolnykh from Novyi Kuvak located in Shentalinsky district (northeast of Samara region). The genus Kerpia for ginkgo similar leaves was set by S.V. Naugolnykh in 1995 on the material from the Kungurian stage of the Middle Urals. Typical species of this genus is Kerpia macroloba Naugolnykh. In the diagnosis of the genus S.V. Naugolnykh showed the most important signs of this genus: presence of lobes and sinuses of the 1st and 2nd order, distinct petiole and two veins included in lamina from the petiole. Later, in 2001, from the sediments of Kazanian stage of the Southern Urals S.V. Naugolnykh described a new species Kerpia belebeica Naugolnykh. In 2013 in Novyi Kuvak location we found impressions of ginkgo similar leaves with on the one hand a great similarity with the known members of the genus Kerpia ( Kerpia macroloba and Kerpia belebeica ), but on the other hand they are clearly not identical to this representative at the species level. According to the results of the study of these impressoins in 2014 we described a new species of the genus Kerpia - Kerpia samarica N.S. Bukhman et L.M. Bukhman, 2014. In this paper we give description of both known and new findings of species Kerpia samarica and a comparison of this species with other species of the genus Kerpia .

In pursuit of developing fast and accurate species-level molecular identification methods, we tested six DNA barcodes, namely ITS2, matK, rbcLa, ITS2+matK, ITS2+rbcLa, matK+rbcLa and ITS2+matK+rbcLa, for their capacity to identify frequently consumed but geographically isolated medicinal species of Fabaceae and Poaceae indigenous to the desert of Cholistan. Data were analysed by BLASTn sequence similarity, pairwise sequence divergence in TAXONDNA, and phylogenetic (neighbour-joining and maximum-likelihood trees) methods. Comparison of six barcode regions showed that ITS2 has the highest number of variable sites (209/360) for tested Fabaceae and (106/365) Poaceae species, the highest species-level identification (40%) in BLASTn procedure, distinct DNA barcoding gap, 100% correct species identification in BM and BCM functions of TAXONDNA, and clear cladding pattern with high nodal support in phylogenetic trees in both families. ITS2+matK+rbcLa followed ITS2 in its species-level identification capacity. The study was concluded with advocating the DNA barcoding as an effective tool for species identification and ITS2 as the best barcode region in identifying medicinal species of Fabaceae and Poaceae. Current research has practical implementation potential in the fields of pharmaco-vigilance, trade of medicinal plants and biodiversity conservation.
