Syntypes: ZMA 110451-52 (1, 2). Type information: Nijssen et al. 1982:66 [ref. 19236]. Original genus should have been Macrourus. Objectively invalid; preoccupied by Macrurus fasciatus Günther 1878. However, in the original description Weber used two names: M. fasciatus (pasted over with vittatus on p. 157) and vittatus on Pl. 1 (fig. 5) and on p. 618; the name fasciatus was used in the index (p. 685, 694). The original on p. 157 at the California Academy of Sciences has strip with vittatus typewritten in the same style as the genus and glued over fasciatus on p. 157. Gilbert & Hubbs 1920:559 [ref. 1638] used M. vittatus without mention of fasciatus. Weber & de Beaufort 1929 [ref. 16063] mentioned both species and state (unfortunately) that vittatus is a misprint; technically they serve as first revisers selecting fasciatus over vittatus. This means that Macrurus fasciatus Weber 1913 is preoccupied and is objectively invalid. •Valid as Ventrifossa fasciata (Weber 1913) -- (Iwamoto 1979:153 [ref. 2311], Paxton et al. 1989:329 [ref. 12442], Iwamoto in Cohen et al. 1990:296 [ref. 18936]). •Synonym of Lucigadus microlepis (Günther 1878) -- (Iwamoto & Merrett 1997:528 [ref. 23710]). 1°Homonym.
