“…The aim of the study was to determine the Krusen sterniella genus position in the Zoarcidae fish family based on molecular genetic study. This approach dem onstrated a high effectiveness in solving similar prob lems on the development of systematics of other taxa from the Zoarcoidei suborder (Radchenko et al, 2008(Radchenko et al, , 2010a(Radchenko et al, , 2010b(Radchenko et al, , 2011(Radchenko et al, , 2012Chereshnev et al, 2009).…”

Using the analysis of variability of mitochondrial and nuclear DNA genes, it was established that the Krusensterniella genus is included in the Gymnelinae subfamily and, along with the Gymnelopsis genus, generates a group of taxa of species devoid of ventral fins. Considerable genetic differences between the Krusensterniella genus and the group of genera of Gymnelinae fish with ventral fins (Hadropareia, Magada nichthys, Bilabria, and Davidijordania) were demonstrated. Differences between the Krusensterniella species correspond to the level interspecific differentiation in closely related Lycodinae subfamily.

Mitochondrial DNA (mtDNA) at Co-1 gene region was sequenced for 7 scorpion fish species (in total, 16 sequences of at least 552 bp) from the Far East of Russia and compared with 15 other sequences of Scorpaeniformes comprising altogether 29 scorpion-like fish sequences and two outgroup sequences (Cypriniformes). The analysis of the protein-coding Co-1 gene revealed statistically substantiated bias in the (T + C) : (A + G) content, proving basic findings. The average scores of p-distances for different scales of the evolutionary history at Co-1 gene revealed a clear pattern of increased nucleotide diversity at four different levels: (1) intraspecies, (2) intragenus, (3) intrafamily, and (4) intraorder. The scores of average p-distances for the compared fish groups were: (1) 1.00 ± 0.20%, (2) 3.80 ± 0.20%, (3) 12.40 ± 1.20%, and (4) 18.00 ± 0.38%, respectively (mean ± SE). These data support the concept that speciation in the order Scorpaeniformes, in most cases, follows a geographic mode through accumulation of numerous small genetic changes over a long period of time. However, intraspecies diversity was surprisingly high among scorpionfish. Phylogenetic trees for 29 sequences of scorpionfish and 2 other fishes belonging to ray-finned fishes (Actinopterigii) were developed using Co-1 gene and four different analytical approaches: Bayesian (BA), maximum likelihood (ML), neighbour-joining (NJ), and maximum parsimony (MP). The analysis revealed a monophyletic origin for the representatives of Cottidae, which is the principal scorpionfish family investigated (100, 96, 98% support level in our BA, MP, and NJ analyses). Similarly, the monophyletic origin of up to the three compared scorpion-like fish genera was supported by molecular phylogenetic data. Species identification on individual basis (barcoding tagging) was high. A few taxonomic complications arose during the analysis and they are discussed here in.
