Two new species of philometrid nematodes (Nematoda: Philometridae) in Epinephelus coioides (Hamilton, 1822) from the South Bali Sea, Indonesia

Abstract

Based on light and scanning electron microscopy, two new species of philometrid nematodes, Spirophilometra endangae sp. nov. and Philometra epinepheli sp. nov. (Nematoda: Dracunculoidea: Philometridae) are described from Epinephelus coioides (Hamilton, 1822) (Perciformes: Serranidae) from the South Bali Sea, Indonesia. Spirophilometra endangae sp. nov. was isolated from the fins of E. coioides. The new species can be distinguished from the most closely related S. eichleri Parukhin, 1971 by a larger total body length and the site of infection in the host. The new species differs from S. centropomi (Caballero, 1974) also in the larger body size of the gravid females and the site of infection in the host. S. en-dangae sp. nov. differs from S. pacifica (Moravec, Santana-Pineros, Gonzales-Solis & Torres-Huerta, 2007) in the struc-ture and arrangement of the spines on the middle part of the body, the infection site of the worm, the type host and the zoogeographical host distribution. Philometra epinepheli sp. nov. differs from all other Philometra spp. congeners so far recorded from Ephinepelus groupers in the total body length and the site of infection. This is the first opercula-infecting species of Philometra described from the fish family Serranidae.

Parasites of the grouper fishEpinephelus coioides(Serranidae) as potential environmental indicators in Indonesian coastal ecosystems

“…Taxonomical and ecological studies on fish parasites from Indonesia have been intensified in recent years (e.g. Palm et al , 2007, 2008, 2011; Yuniar et al , 2007; Palm, 2008, 2011; Bray & Palm, 2009; Kuchta et al , 2009; Rückert et al , 2009a, b, 2010; Kleinertz, 2010, Kleinertz et al , 2012, Dewi & Palm, 2013; Kuhn et al , 2013), taking into account the high parasite biodiversity at this tropical location. The purpose of the present study is an assessment of the fish parasite fauna of E. coioides , a widely distributed and rapidly developing mariculture species in Indonesia, from additional sampling sites.…”

Philometrids (Nematoda: Philometridae) in carangid and serranid fishes off New Caledonia, including three new species

“…coioides in the South Bali Sea, Indonesia [2]. Subsequently, the same two species were recorded in E .…”

“…Recent studies carried out in adjacent waters off southern Indonesia and northern Australia by Moravec et al [27], Dewi & Palm [2] and Moravec & Diggles [16] revealed the presence of several previously unknown philometrids in marine fishes, which may also occur in the New Caledonia region. Additional samples of philometrid nematodes, including three new species of Philometra , were collected from carangid and serranid perciform fishes.…”

Assessment ofEpinephelus coioides(Hamilton, 1822) aquaculture systems in the Gulf of Tonkin, Vietnam, by using fish parasites

“…For the ectoparasites, identification followed Whittington, Deveney, and Wyborn (), Dang, Levsen, Schander, and Bristow () (Monogenea), Bruce () (Isopoda), Ho and Lin () Ho, Liu, and Lin () (Copepoda). For the endoparasites, identification followed Bray and Cribb (), Bray and Palm (), Bray and Justine (), Yamaguti (, ) (Digenea), Palm () (Cestoda), Moravec, Justine, and Rigby (), Anderson, Chabaud, and Willmott (), Dewi and Palm (), Gibbons () (Nematoda), Lom and Dyková (, ) and Vo et al. () (Protozoa).…”
