DISCUSSION: Halipeurus vincesmithi has closer morphological affinities with H. raphanus , H. pelagicus , H. pelagodromae and H. nesofregettae than with all other species of Halipeurus . Those affinities are not surprising considering that its host, Oceanodroma matsudairae , and all the hosts of the four species mentioned above belong to the storm petrel family Hydrobatidae . Halipeurus vincesmithi is easily distinguished from H. pelagicus , H. pelagodromae and H. nesofregettae by its much greater length and width in both sexes ( Table 1), by robust male antennae, by unique male genitalia (compare Fig. 58 View FIGURES 56 – 60 with Figs 59 View FIGURES 56 – 60 , 63 View FIGURES 61 – 65 ), and by the chaetotaxy of the ventral terminalia in both sexes (compare Fig. 34 View FIGURES 34 – 37 with Figs 32, 33 View FIGURES 28 – 33 , 35 View FIGURES 34 – 37 for males, and Fig. 49 View FIGURES 49 – 53 with Figs 47, 48 View FIGURES 43 – 48 , 50 View FIGURES 49 – 53 for females). Further, males of H. vincesmithi can be separated from males of H. raphanus by the shape of the clypeal signature, ventral terminalia and genitalia (compare Figs 8 View FIGURES 3 – 12 , 34 View FIGURES 34 – 37 , 58 View FIGURES 56 – 60 with Figs 10 View FIGURES 3 – 12 , 36 View FIGURES 34 – 37 , 60 View FIGURES 56 – 60 respectively), while females can be distinguished by the shape of the clypeal signature (compare Fig. 8 View FIGURES 3 – 12 with 17), and the length of the terminal pair of peg-like setae in addition to the shape plus chaetotaxy of the subgenital plate (compare Fig. 49 View FIGURES 49 – 53 with 52).
