Haliotrema minutospirale Yamaguti, 1968

Type host.

Parupeneus cyclostomus ( Lacépède) ( Mullidae ).

Other host and localities.

Yamaguti (1968) recorded this species from gills of P. cyclostomus , P. pleurostigma (Bennett) and P. multifaciatus (Quoy and Gaimard) for Hawai’i. Palm and Bray (2014) also recorded this species from P. cyclostomus in the same locality (all Mullidae ).

Current host.

Mulloidichthys flavolineatus ( Mullidae ) (New host).

Site infection.

Gills.

Prevalence and mean intensity.

19,2 and 27 ± 18 (n=52).

Specimens deposited.

CHCM No. 539 (paratypes) (1 slide, 1 specimen), USNM No. 1459850 (voucher) (1 slide, 1 specimen)

Remarks.

The morphology of the copulatory complex is a relevant characteristic for its identification. Its MCO consists of an anterior, spiral, flanged portion and a posterior, cylindrical portion, enclosed in a sheath of circular muscular fibres. The presence of H. minutospirale on the gills Mulloidichthys flavolineatus from Palmyra Atoll represents both a new host and a new geographical record.
