Hatschekia bicaudata Kabata, 1991

Type host.

Chaetodon aureofasciatus Macleay ( Chaetodontidae ).

Other host and localities.

Chaetodon aureofasciatus ( Chaetodontidae ) from Australia ( Kabata 1991). Chaetodon auripes Jordan & Snyder ( Chaetodontidae ) from Seto, Wakayama Prefecture, Japan ( Izawa 2016).

Current host.

Chaetodon auriga and Chaetodon lunula ( Chaetodontidae ).

Site of infection.

Gills.

Prevalence and mean intensity.

23.1 and 7.3 ± 3.1 (n = 13) to Chaetodon auriga ; 14.3 and 5 ± 1.4 (n = 14) to Chaetodon lunula .

Specimens deposited.

CHCM No. 577 (voucher) (1 vial, 1 specimen ♀) (from Chaetodon auriga ). CHCM No. 578 (voucher) (1 vial, 1 specimen ♀) (from Chaetodon lunula ). USNM No. 1550606 (voucher) (1 vial, 1 specimen ♀) (from Chaetodon lunula ).

Remarks.

Our samples corresponded to a single mature female from each host, which were not dissected for morphological analysis. Nonetheless, these parasitic copepods resemble H. bicaudata in its habitus, antenna, maxilla, and armature of legs 1 and 2, as well as in its preferred hosts, which are butterfly fishes distributed in warm waters from Australia to Japan (see Izawa 2016).
