Spirostreptus geayi — Brölemann 1900 . Mémoires de la Société Zoologique de France, 13: plate 8, fig. 122. Brölemann (1900: 125) notes that the figure is meant to accompany the description of the species in Annales de la Société Entomologique de France, 67(3).

Gymnostreptus geayi — Attems 1914b . Zoologica, Stuttgart, 25(65, 66): 132, lists Venezuela: Haut et Bas Sarare.

Nanostreptus geayi — Krabbe, 1982 . Abhandlungen des Naturwissenschaftlichen Vereins in Hamburg, 24: 344, fig. 240, lists Kochliogonopus stechowi and Venezueneptus liber in the synonymy of Nanostreptus geayi . Nanostreptus also listed as valid genus by Hoffman 1980.

Nanostreptus geayi — Jeekel 1999 . Myriapod Memoranda, I: 63.

Kochliogonopus stechowi Verhoeff, 1938 . Zoologische Jahrbücher, 71(1/2): 21, plate 2, figs. 20–24, 32; ST (ZSM), ST FEMALE (ZMHB 12608); synonymized with geayi , see note below [type species of Kochliogonopus ].

Kochliogonopus stechowi — Schubart 1945 . Anais da Academia Brasileira de Ciências, 17: 63.

Kochliogonopus stechowi — Demange 1970 . Bulletin de l’Institut Fondamental d’Afrique Noire, 32(2): 383; lists Nanostreptus as a synonym of Spirostreptus : 403.

– stechowi — Moritz & Fischer 1974 . Mitteilungen aus dem Zoologischen Museum in Berlin, 50(2): 373.

Venezueneptus liber Causey, 1954 . Proceedings of the Biological Society of Washington, 67: 58, figs.7–8; HT MALE (INHS 7), PT FEMALE (INHS 8); Demange (1970: 383); synonymized liber with Kochliogonopus stechowi [type species of Venezueneptus ].

Note: Demange considered Nanostreptus a synonym of Spirostreptus ( Demange 1970: 403) and synonymized Venezueneptus liber under Kochliogonopus stechowi , treating Kochliogonopus as a valid genus. Hoffman (1980) and Krabbe (1982) list Kochliogonopus as a synonym of Nanostreptus and considered Nanostreptus a valid genus. It is unclear at this point, who revalidated Nanostreptus and established the synonymy of Kochliogonopus under Nanostreptus . Krabbe (1982) listed Kochliogonopus stechowi as a synonym to Nanostreptus grayi . It is unclear who established this species-level synonymy.

Distribution in Venezuela: Morichal, Delta-Amacuro State; El Valle, near Caracas, Miranda State ( Chamberlin 1941c); Upper and lower Sarare River, without exact locality data ( Brölemann 1898b).
