The name Muelleria was first introduced by Frenguelli in 1924 (ref. 000969) p. 256 (p. 98 of reprint) as a new subgenus of Navicula. Two species were included, Navicula linearis (O. Müller) Cleve and Navicula porto-monttana Cleve. Following the description of Navicula linearis, Frenguelli gave a detailed diagnosis of his new subgenus but did not designate or indicate a type. Later, Frenguelli (1945) elevated the subgenus to generic level, including in it three species, Muelleria linearis (Müll.) Freng., M. porto-monttana (Cleve) Freng. and M. patagonica (Müll.) Freng. Although no generic description was given, the generic name is valid because a full and direct reference to its publication at the level of subgenus was given. Again, Frenguelli (1945) failed to designate or indicate a type. Lectotypification was effected by Round, Crawford & Mann (1990), p. 695, who chose Muelleria linearis (O. Müller) J. Frenguelli 1945. Spaulding and Stoermer (1997), p. 97, erroneously state that Frenguelli 1924 designated D. linearis as the type of Navicula subg. Muelleria. |

Type by monotypy. This genus name was erroneously spelt Opheporopsis p. 205 but correctly spelled Opephoropsis in other parts of the text. The name of the type species is incorrectly spelled O. schwartzii in Frenguelli, and should be corrected to swartzii . |
