Clay (1962) states concerning A. piceus lari (Packard, 1870) and 

 A. piceus piceus (Denny, 1842) : "The populations of Actomithophilus 

 found on the Laridae have not been revised in detail, and must wait for 

 a larger amount of material from more host species. In general, indi- 

 viduals from the Sterninae (i. e., piceus Denny) are smaller than those 

 from the Larinae (i. e., lari Packard)."
