Comments ING (1996) indicates that a reprint of ref. 000285 was published in 1836, in which the genus was described p. 22. This reprint (that we have not seen) would therefore constitute the original publication of the generic name. The name Podosphenia, as well as the combination Podosphenia nana also appeared in Ehrenberg 1836 (ref. 002226), p. 56, as nomina nuda (no description or illustration given). Genus Podosphenia is described in Ehrenberg 1837 (ref. 000285), p. 173; no species are originally included. Also described in Ehrenberg 1838, p. 213 (ref. 000288), where 4 species are included, but no type is designated. See also Ehrenberg 1838 (ref. 000288), p. 215 (" Nachtrag zur Gattung Podosphenia").
