Philometra ocularis Moravec, Ogawa, Suzuki, Miyaki & Donai, 2002

Host: Variola louti (Forsskål, 1775) ( Perciformes : Serranidae ).

Site of infection: Eye cavity.

Date of collection: 14 November 2016.

Prevalence: 1 infected/1 examined.

Specimens deposited: Museum Zoologicum Bogoriense, Indonesia (MZBNa 731).

Remarks. One anterior and one posterior part of a subgravid female of P. ocularis was reported from the eye cavity of a single individual Variola louti . This species is characterized by having four large, fleshy cephalic papillae ( Moravec et al. 2002, Moravec & Justine 2005; Moravec 2006). Body fragments of the subgravid females of the available specimens only provided few information for species identification. However, this species was easily recognized by having the fleshy cephalic papillae and the site inside the eye cavity, allowing species identification. In Indonesia, P. ocularis has been reported from E. coioides (Hamilton, 1822) and E. fuscoguttatus (Forsskål, 1775) from Lampung Bay by Rueckert et al. (2009) and from E. ongus (Bloch, 1790) from Karimunjawa ( Neubert et al. 2016). This species parasitizes the eye cavity of many serranid fish with E. septemfasciatus (Thunberg, 1793) as the type host ( Moravec et al. 2002). The presence of P. ocularis has been reported already from V. louti in the South Pacific Ocean by Moravec & Justine (2005).
