inaequidens Gervais, 1847:277–278 (31 May; Jeekel (1971:382, endnote 70)).

Holotype: not known to exist, not present in MNHP (J.­J. Geoffroy, pers. comm.), not found in 2005; type locality: unknown; stated as New York, USA (uncertain whether New York State or City), but no centipede of the size reported by Gervais (0.190 m [7.48 in.]) occurs in or near New York .

Original rank: species. Current rank and status: nomen inquirendum, by implication of Attems (1930). Kraepelin (1903) listed this name as a questionable synonym of H e miscolopendra punctiventris (Newport, 1844) (= H. marginata (Say, 1821)); Brölemann (1909) regarded it as a synonym of S. alternans Leach, 1815; and Attems (1930) cited it as an unrecognizable species.

Remarks: Although uncertain that they were conspecific with Gervais’ species, Wood (1862) applied the name, inaequidens, to specimens from Illinois at the Smithsonian Institution and one from Massachusetts housed at the MCZ; however, they are quite different, as Gervais’ form was much larger. Meinert (1886) correctly perceived this difference when he proposed S. woodi for S. inaequidens sensu Wood, 1862 . Hoffman & Shelley (1996) and Shelley (2002) cited S. inaequidens sensu Wood, 1862, and S. woodi Meinert, 1886, as synonyms of H. marginata . As the type no longer exists, the identity of S. inaequidens Gervais, 1847, is unknown, and the name must be regarded as a nomen inquirendum.
