Philometroides marinus Moravec & Buron, 2009

Host: Rachycentron canadum (Linnaeus, 1766) ( Perciformes , Rachycentridae ).

Site of infection: Body cavity.

Date of collection: 26 September 2013.

Prevalence: 1 infected/1 examined.

Specimens deposited: Museum Zoologicum Bogoriense, Indonesia (MZBNa 732).

Remarks. One specimen of P. marinus was reported from the abdominal cavity of one individual Rachycentron canadum . This species was originally described from the same host from off the Atlantic coast of South Carolina (Moravec & de Buron 2009), and can be easily recognized by having small cuticular bosses only on the anterior part of the body, two large caudal projections, body of fully gravid female up to 550 mm, and the site of infection (body cavity) (Moravec & de Buron 2009). This is the first record from Balinese waters, thus extending its range of distribution to Indonesia. The species can be distinguished from the most similar species P. trichiuri and P. indonesiensis (both from Indonesian waters) by the much longer body length of the gravid female (13.0– 22.4 and 143 mm vs. 645 mm).

One Cheilopogon atrisignis (Jenkins, 1903) , two Cephalopholis cyanostigma (Valenciennes, 1828) (gonads), one Epinephelus coeruleopunctatus (Bloch, 1790) (gonads), one Nemipterus japonicus (body cavity) and one Sonorolux fluminis Trewavas, 1977 (gonads) were found to be infected with philometrid nematodes. However, because of their poor condition, their identification was not possible. Moreover, one Cephalopholis sexmaculata (Rüppel, 1830) (mouth cavity), one Epinephelus fasciatus (Forsskål, 1775) (mesentery), one Nemipterus japonicus (eye cavity), and one Variola louti (gonad) was found to be infected with Philometra sp. (see Table 1).
