diagnosis
Diagnosis. Opercular verticil with 7 – 11 spines, dorsal one stout, elongated, terminating in three sharply pointed ventrally curving hooks that may be of similar size, but generally one large terminally and two smaller ones laterally; other verticil spines short, curved outwards, with pointed tips. Spinules and central tooth absent. Funnel with 22 – 26 chitinized radii ending in swollen or sharp tips, base of funnel elongated, chitinized, merging into constriction. Grooves separating radii extending 1 / 2 of funnel length (Fig. 7).
discussion
Remarks. Hydroides minax can be easily confused with H. lirs n. sp. (see Remarks after description of H. lirs n. sp.). In addition to morphological differences, the two species appear to differ ecologically: specimens of H. minax were collected from coral rubble or rocks, while those of H. lirs n. sp. were found embedded in living corals.
distribution
Distribution. Widely distributed in the Indo-West Pacific, Lessepsian migrant to the Levant Mediterranean.
