Type material. Lectotype of Philonthus perplexus (here designated), 3, with labels: “ Chili ” (green), “ Spatulonthus perplexus Fairmaire et Germain ” (unknown handwriting, white), “ Lectotype Philonthus perplexus Fairmaire et Germain, 1861 / Des. Chani-Posse de Maus 2008” ( MNHN). Paralectotypes: 3, Ƥ, with labels: “ Chili ” (green), “ Paralectotype Philonthus perplexus Fairmaire et Germain, 1861 / Des. Chani- Posse de Maus 2008” ( MNHN). Males were dissected; in each case the aedeagus was glued on a different plate and attached to the beetle.

Additional material. CHILE: 3, Ƥ, Maipo, 12.XI.1972, Col. G. Arriagada ( MNHN). Diagnosis. See Smetana (1995: 243).

Notes. Stephens (1832: 237) described P. longicornis based on specimens from London. I have not seen the original material but I have no doubt that P. p e r p l e x u s is the species that Stephens described, as interpreted later by other authors (e.g. Sharp 1885; Blackwelder 1943; Smetana 1958, 1995).

Comments. Philonthus perplexus was considered to be a synonym of P. longicornis since Fauvel (1869) until Coiffait and Saiz (1968) treated it as a valid species. The type material of P. perplexus and the examined material of P. longicornis are similar in all external characters and identical in the shape of aedeagus. Therefore, these names are considered to be synonyms (confirmed synonymy).
