Quadraceps birostris (Giebel, 1874)

Nirmus birostris Giebel, 1874: 174 .

Colima: Onychoprion anaethetus, Socorro Island, 1897, R.C. McGregor (Kellogg & Mann 1912). Notes: Specimens of Q. birostris were identified as “ Nirmus gloriosus Kellogg and Kuwana ” by Kellogg & Mann (1912). This record is most likely the result of a contamination because Q. birostris is a regular and natural parasite of Onychoprion fuscatus only (see Price et al. 2003). The locality (Socorro Island) was recorded as belonging to the State of Baja California; however, this island is in the Archipelago of Revillagigedo located in the State of Colima (INEGI 2014).
