FIGURE 1. A track chart and the stations (ST) of the cruise of the (TR/V) TOYOSHIO MARU. Circles and characters denote stations; solid blue line, ST-1–8 of the Cruise 2014-28; dotted red line, ST-1–15 of the Cruse 2015-28. During the Cruise 2015- 28, the surveys at the ST-7, 8, 12, 13, and 14 failed because of stormy weather, and alternately St-8A and 14A were selected for the location of the surveys.

FIGURE 6. Phylogenetic tree for 15 species of Salmoneus and Jengalpheops rufus Anker & Dworschak, 2007 used as an outgroup taxon; obtained by ML analysis of 16S rRNA gene sequences using the TVM + G + I substitution model. The best tree with the highest log likelihood (-1870.53) is shown. Bootstrap supports of greater than 80% are indicated at nodes as percentage values. There was a total of 514 bp in the final dataset trimmed with GBlocks.
