Genus Pseudonezumia Okamura, 1970

Pseudonezumia Okamura, 1970:38–39 (type-species Pseudonezumia japonicus Okamura, 1970 by original designation).

Paracetonurus Marshall, 1973:615–616 (type-species Macrourus parvipes Smith and Radcliffe, 1912 by original designation).

DISTINGUISHING FEATURES.— BR 7 or 8; V 6, rarely 5 or 7, situated below posterior end of head; P 16–18; anus slightly removed from A; head much deeper than wide ( P. japonica ) to relatively broad and deep (other spp.); sensory canals expanded, well developed; head and body almost fully scaled; body scales small, exposed field with erect awl-shaped spinules in subparallel to slightly divergent rows, reticulations on scales; suborbital ridge without modified scales; snout broad, tip and lateral angles lacking tubercles; teeth in narrow bands, somewhat enlarged in outer premaxillary and inner dentary series. No apparent light organ developed.

REMARKS.— We are treating the genus Paracetonurus Marshall, 1973 as a synonym, although this has not been adequately confirmed. Sazonov and Shcherbachev (1982:11) provided a good diagnosis and discussion of relationships of the genus (as Paracetonurus ); they listed four species as belonging to the genus, including P. flagellicauda (Koefoed, 1927) , P. parvipes (Smith and Radcliffe, 1912) , and P. cetonuropsis (Gilbert and Hubbs, 1916) , and their new one P. pusillus , but not P. japonica Okamura, 1970 . Of the five species, only one is known from Taiwan.
