Actornithophilus incisus (Piaget, 1880)

Colpocephalum incisum Piaget, 1880: 569, pl. 47, fig. 9.

Colima: Anous stolidus ridgwayi, Socorro Island, 1897, R.C. McGregor (Kellogg & Mann 1912); Onychoprion anaethetus, Socorro Island, 1897, R.C. McGregor (Kellogg & Mann 1912).

Notes: Specimens of A. incisus were identified by Kellogg & Mann (1912) as “ Colpocephalum milleri Kellogg and Kuwana ”. The record from the bridled tern ( Onychoprion anaethetus) is likely the result of a contamination because A. incisus is a regular and natural parasite of Anous stolidus 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).
