1747. Pediculus pubis Linnaeus 1747, No. 1154. 
1758. Pediculus pubis Linnaeus 1758, p. 611; also 1761, p. 475, No. 1940: “Habitat in 
hominum immundorum pube et ciliis”; also 1767, p. 1017: “Hospitatur in 
hominis immundi pube, rarius in superciliis; pellitur Oleo Tabaci.” See also 
Fabricius, 1775, p. 805, and 1794, iv. p. 418, who gives a brief Latin description. 
1759. Pediculus inguinalis Reichard 1759, fide Eysell, 1913, p. 48, and Castellani and 
Chalmers, 1913, p. 631. 
1804. Pediculus pubis Latreille 1804, p. 96, he gives a brief description; Stephens, 1829, 
p. 329, cites Berkenhout, and Turton (see Bibliography) and “Stew. n. 279.” 
1815. Pthirus inguinalis Leach 1815, Ed. Encycl. vol. ix. p. 77 (Stephen, 1829, gives the 
date 1810, but Enderlein, 1904, corrects it to 1915); Leach, 1814-18J 7, Zool. 
Misc. vol. ill. p. 65, writes: “Habitat in hominis pube, grandebulis, villis, super¬ 
ciliis, ciliis, mustacibusque, cuti adhaerens.” 
1835. Phthirius inguinalis Burmeister 1836, Handb. Ent. n. pt. 1, pp. 52, 58 ( fide Dalla 
Torre, 1908, p. 9); in Denny, 1842, pp. 8-11; in Giebel, 1874, pp. 23-27, PI. I, 
fig. 8; in Piaget, 1880, p. 628. 
1855. Phthirius pubis Kuchenmeister 1855, p. 445. 
Remarks: The specific name pubis Linnaeus 1758 stands, the generic name 
Pediculus is superseded by Phthirus Leach 1815, therefore the correct name 
is Phthirus pubis (Linnaeus 1758) Leach 1815. Note the bracket. 
There is some excuse for Redi’s specific name inguinalis persisting, but the 
Linnaean name must stand in accordance with the rules of zoological nomen¬ 
clature. 
Enderlein (1904, p. 136), Dalla Torre (1908, p. 9), and Ferris (1916, p. 138) give 
the name rightly as Phthirus pubis. The name Phthirus was misspelt by Bur¬ 
meister (1835) and consequently by many authors since who followed in his 
track, spelling it Phthirius. The name is also frequently misspelt Phtirius, 
vide ; Dubreuilh and Beille (1895, p. 107); Megnin (1906, p. 87); Mjoberg (1910, 
p. 171); Silvestri (1911, p. 200), etc. 
Vulgar Names: Eng. crab-louse : Fr. morpion ; Ital. piattola ; Ger. Schamlavs, Filzlaus ; 
Dan.-Swed. Flatlus.
