Genus Lycenchelys Gill, 1884 (Japanese name: Hebigenge-zoku) Lycenchelys Gill, 1884: 180 (type species by subsequent designation: Lycodes muraena Collett, 1878). Lycodophis Vaillant, 1888: 311 (type species by monotypy: Lycodes albus Vaillant, 1888). Embryx Jordan & Evermann, 1898: 2458 (type species by original designation: Lycodopsis crotalinus). Lyciscus Evermann & Goldsborough, 1907: 342 (type species by monotypy: Lycodopsis crotalinus Gilbert, 1890). Apodolycus Andriashev, 1979: 29 (type species by original designation: Apodolycus hureaui Andriashev, 1979). Diagnosis. Vertebrae 19–30 + 66–118 = 85–144; suborbital bones 6–10; suborbital pores 6–11; 1st dorsal-fin pterygiophores associated with vertebrae 2–21, with 0–16 free pterygiophores; palatopterygoid series weak; oral valve weak; pseudobranch, pelvic fins, and vomerine and palatine teeth usually present; scales, pyloric caeca and lateral line(s) present (Anderson, 1994; Shinohara & Matsuura, 1998; Shinohara & Anderson, 2007; this study). Distribution. Widespread in the Pacific (mainly in northwestern and eastern), Atlantic, Arctic and Southern oceans, and around the Kerguelen Islands (Anderson, 1994, 2006; Anderson & Fedorov, 2004; Anderson & Møller, 2007; Shinohara & Anderson, 2007; Thiel et al., 2018; this study). Maximum collection depth 5320 m, in the Peru- Chile Trench (holotype of Lycenchelys atacamensis Andriashev, 1980) (Andriashev, 1980; Anderson, 1988, 1995; Anderson & Fedorov, 2004). Remarks. The genus Lycenchelys currently includes about 60 species (Anderson & Fedorov, 2004; Anderson, 2006; Anderson & Møller, 2007; Shinohara & Anderson, 2007; Nelson et al., 2016; Thiel et al., 2018). This study recognizes 11 species of Lycenchelys in Japanese waters, in accordance with recent studies (i.e., Shinohara & Anderson, 2007; Hatooka, 2013). The diagnosis of the genus above mainly follows Anderson (1994), except for the numbers of suborbital pores and total vertebrae, variations in which were reported ...
