Genera in the family or subfamily Lepisosteidae: [ 9 ] records

Acus Catesby [M.] 1771:30 Fem. Not available; published in a rejected work on Official Index (Opinion 89, Opinion 259). Suppressed. Lepisosteidae.

Atractosteus (subgenus of Lepisosteus) Rafinesque [C. S.] 1820:171 Masc. Lepisosteus (Atractosteus) ferox Rafinesque 1820. Type by monotypy. Also in Rafinesque 1820:75 (Dec.) [ref. 3592]. See Grande 2010:292 [ref. 31167] for included fossil synonyms. The unused name Litholepis Rafinesque 1818 is in the synonymy of Atractosteus Rafinesque 1820; the latter is here regarded as a nomen protectum due to prevailing usage. •Synonym of Lepisosteus Lacepède 1803 -- (Suttkus 1963:69 [ref. 7110]). •Valid as Atractosteus Rafinesque 1820 -- (Wiley 1976:61 [ref. 7091]); or a valid subgenus of Lepisosteus (e.g., Robins et al. 1980:70 [ref. 7111]). •Valid as Atractosteus Rafinesque 1820 -- (Wiley 2003:673 [ref. 26988], Ferraris in Reis et al. 2003:29 [ref. 27061], Grande 2010:292 [ref. 31167], Wright et al. 2012:850 [ref. 32445]. Angulo et al. 2013:989 [ref. 33194], Esmaeili et al. 2018:7 [ref. 36089]). Nomen Protectum. Current status: Valid as Atractosteus Rafinesque 1820. Lepisosteidae.

Cylindrosteus (subgenus of Lepisosteus) Rafinesque [C. S.] 1820:168 Masc. Lepisosteus (Cylindrosteus) platostomus Rafinesque 1820. Type by subsequent designation. Type designated by Jordan & Copeland 1877:160 [ref. 5961]. Also in Rafinesque 1820:72 (Dec.) [ref. 3592]. •Synonym of Lepisosteus Lacepède 1803 -- (Suttkus 1963:69 [ref. 7110], Wiley 1976:41 [ref. 7091], Grande 2010:27 [ref. 31167]). Current status: Synonym of Lepisosteus Lacepède 1803. Lepisosteidae.

Lepisosteus Lacepède [B. G. E.] 1803:331 Masc. Lepisosteus gavial Lacepède 1803. Type by subsequent designation. Type designated by Jordan & Gilbert 1877:84 [ref. 4907]. Lepidosteus of authors is an incorrect subsequent spelling or unjustified emendation (see Briggs 1961:162 [ref. 13439]). Original spelling of species is gravial; often cited as gravialis. •Valid as Lepisosteus Lacepède 1803 -- (Suttkus 1963 [ref. 7110], Wiley 1976:41 [ref. 7091], Jenkins & Burkhead 1994:196 [ref. 21581], Wiley 2003:674 [ref. 26988], Grande 2010:27 [ref. 31167], Wright et al. 2012:848 [ref. 32445], Sinopoli et al. 2024:139 [ref. 40953]). Current status: Valid as Lepisosteus Lacepède 1803. Lepisosteidae.

Litholepis Rafinesque [C. S.] 1818:445 Fem. Litholepis adamantinus Rafinesque 1818. Type by monotypy. Regarded (e.g., by Jordan 1917:109 [ref. 2407]) as based on a mythical gar, but original description is reasonably correct for Lepisosteus spatula (see Markle 1997:445 [ref. 23370]). The unused name Litholepis Rafinesque 1818 is technically a senior synonym of Atractosteus Rafinesque 1820, but is here declared a nomen oblitum. •Synonym of Lepisosteus Lacepède 1803 -- (Suttkus 1963:69 [ref. 7110], Grande 2010:27 [ref. 31167]). •Synonym of Atractosteus Rafinesque 1820. Nomen Oblitum. Current status: Synonym of Atractosteus Rafinesque 1820. Lepisosteidae.

Psalidostomus Minding [J.] 1832:121 Masc. Esox osseus Linnaeus 1758. Misprinted on p. 121 as Palidostomus, corrected in corrigenda after p. 131. An objective synonym of Lepisosteus Lacepède 1803. •Synonym of Lepisosteus Lacepède 1803 -- (Grande 2010:27 [ref. 31167]). Current status: Synonym of Lepisosteus Lacepède 1803. Lepisosteidae.

Psalisostomus Klein [J. T.] 1781:154 Masc. Not available, published in a work that does not conform to the principle of binominal nomenclature. Original not checked. Suppressed. Lepisosteidae.

Psallisostomus Walbaum [J. J.] (ex Klein) 1792:581 Masc. Esox osseus Linnaeus 1758. Type by subsequent designation. Not available, published in a part of work rejected for nomenclatural purposes in Opinion 21 (1938). Based on Klein 1744:23 [ref. 30141], with reference to 'Acus Piscis' of Willughby 1686:App. p. 2, Pl. 3, fig. 2 [ref. 30164]. Probably can date to Fowler 1906:89 [ref. 7112, month uncertain] with type by monotypy (also Fowler 1906:81 [ref. 1371, 26 July 1906]). •In the synonymy of Lepisosteus Lacepède 1803. Suppressed. Current status: Synonym of Lepisosteus Lacepède 1803. Lepisosteidae.

Sarchirus Rafinesque [C. S.] 1818:418 Masc. Sarchirus vittatus Rafinesque 1818. Type by monotypy. Rafinesque 1818:418 published 7 Nov.; also appeared in Nov. in Rafinesque 1818:41 [ref. 3589]. •Synonym of Lepisosteus Lacepède 1803 -- (Suttkus 1963:69 [ref. 7110], Wiley 1976:41 [ref. 7091], Grande 2010:27 [ref. 31167]).
