Type genus: Promecheilus Solier, 1851 [as Promechilus , unjustified emendation of type genus name by Lacordaire (1859: 700), not in prevailing usage]. Comment: original vernacular name available (Art. 11.7.2): first used in latinized form by Handlirsch (1925: 594, as Promecheilinae ), generally accepted as in Lawrence et al. (2010: 563, as Promecheilidae ); incorrect original stem formation, not in prevailing usage. Perimylopidae St. George, 1939: 212 [stem: Perimylop-]. Type genus: Perimylops Mueller , 1884. *Parahelopinae Watt, 1975: 424 [stem: Parahelop-]. Type genus: Parahelops C. O. Waterhouse, 1876. Comment: unavailable family-group name, proposed after 1930 without description or bibliographic reference to such description (Art. 13.1); this name was used several times subsequently, e.g., Elgueta and Arriagada (1989: 37), Lawrence and Britton (1991: 665), Lawrence (1994: 339), but this taxon name remains unavailable (see Lawrence and Newton 1995: 892).
