Other host and localities.

Previous records (as Haliotrema patellacirrus ) on L. lutjanus and L. fulviflamma from South China Sea ( Bychowsky and Nagibina 1971). Kritsky et al.

Current host.

Lutjanus monostigma ( Lutjanidae ) (New host).

Site infection.

Gills.

Prevalence and mean intensity.

33,3 and 145 ± 197 (n=6).

Specimens deposited.

CHCM No. 538 (paratypes) (1 slide, 3 specimen).

Remarks.

Haliotrematoides patellacirrus presents an MCO comprising a proximal platter-shaped base, distal tubular shaft with aloose clockwise coil of about 3/4 of a ring, enclosed in a sheath with a subterminal knob-like projection. Ventral anchor with elongate superficial root, knob-like deep root, shaft slightly narrowed distally and straight, recurved point with delicate superficial grooves. Dorsal anchors with elongate superficial root, inconspicuous (or absent) deep root, straight shaft of varying diameter and recurved point; distal shaft and point superficially grooved. Ventral bar with two submedial pockets along anterior margin; dorsal bar rod-shaped, with subterminal notches, ending slightly narrower than medial portion of bar. The presence of H. patellacirrus from L. monostigma off Palmyra Atoll represents both a new host and a new geographical record. Only one host was found parasitised.
