Prevalence and mean intensity.

7.7 and 8 (n = 13) to Chaetodon auriga ; 28.6 and 2.5 ± 1.7 (n = 14) to Chaetodon lunula .

Specimens deposited.

CHCM No. 564 (voucher) (1 vial, 1 specimen ♂) (from C. auriga ). CHCM No. 565 (voucher) (1 vial, 1 specimen ♂) (from C. lunula ). USNM No. 1550599 (voucher) (1 vial, 1 specimen ♂) (from C. lunula ).

Remarks.

According to Lewis (1967) and Lin and Ho (2007), C. kapuhili is morphologically close to Caligus laticaudus Shiino, 1960. However, the abdomen is 1-segmented in C. kapuhili and 2-segmented in C. laticaudus . We found specimens of C. laticaudus (see below), which facilitated our morphological analysis. Likewise, we identified C. kapuhili based on host preference, since this species has only been found on fish of the genus Chaetodon from the North-West Pacific.
