Material examined: 25 males, 17 females and 2 nymphs (8 samples, EMEC, MONZ) .

Remarks: From the Kellogg Collection, we have identified as Colpocephalum angulaticeps one female reported as “ Colpocephalum unciferum ” and four specimens reported as “ Colpocephalum spineum ” by Kellogg & Kuwana (1902: 484), all labelled with incorrect hosts. Also, we have identified as Colpocephalum angulaticeps one female reported as “ Colpocephalum unciferum ” from “ Fregata aquila ” by Kellogg (1906: 321).

Colpocephalum angulaticeps has been recorded from two species of Fregata , F. minor and F. ariel (Gray, 1845) , while C. spineum parasitises the other two species of that genus, F. aquila ( Linnaeus, 1758) and F. magnificens (see Price et al. 2003: 97, 102).
