The southern South American species of the genus Philonthus Stephens, 1829 (Staphylininae: Staphylinini) are revised using characters of external morphology and male and female genitalia. Three species of Philonthus are transferred to the genus Belonuchus Nordmann, 1837 resulting in the following new combinations: B. aluticollis (Bernhauer, 1921), B. flavicoxis (Bernhauer, 1912) and B. weiserianus (Bernhauer, 1921). Twenty-five valid species are recognized for the region in the present study: Philonthus aeruginosus Nordmann 1837, P. argus Herman 2001, P. bicoloristylus Chani-Posse 2004, P. bonariensis Bernhauer 1909, P. convexicollis Lynch-Arribálzaga 1884, P. cribriventris Bernhauer 1912, P. discoideus (Gravenhorst, 1802), P. figulus Erichson 1840, P. flavolimbatus Erichson 1840, P. hepaticus Erichson 1840, P. jenseni Bernhauer 1912, P. longicornis Stephens 1832, P. lynchi Bernhauer & Schubert 1914, P. pallipes Blanchard 1842, P. pauxillus Solsky 1868, P. politus (Linnaeus, 1758), P. quadraticeps Boheman 1858, P. rectangulus Sharp 1874, P. rubromaculatus Blanchard 1842, P. ruficauda Bernhauer 1934, P. sericans (Gravenhorst, 1802), P. stenocephalus Scheerpeltz 1972, P. varians (Paykull, 1789). Two new species are described: P. floresi and P. bruchianus. Philonthus feralis Erichson 1840, previously recorded for this region, is also redescribed. Diagnoses, redescriptions or descriptions, illustrations, bionomic information and distribution maps for all species are presented. An identification key to the southern South American species of the genus is provided. Lectotypes are designated for Philonthus aeruginosus Nordmann 1837, P. aluticollis Bernhauer 1921, P. apicipennis Lynch-Arribálzaga 1884, P. convexicollis Lynch-Arribálzaga 1884, P. figulus Erichson 1840, P. flavicoxis Bernhauer 1912, P. jenseni Bernhauer 1912, P. pallipes Blanchard 1842, P. rubromaculatus Blanchard 1842, P. stenocephalus Scheerpeltz 1972, P. tucumanensis Bernhauer 1934 and P. weiserianus Bernhauer, 1921.
