Abstract
On the new investigation of some Trematode fauna of Arabian Gulf fishes,
Monascus
sp. a digenea parasite of
and
Helicometrina nimia
of greasy grouper,
Epinephelus tauvina
are register. Fish specimens were collected during the
year 2016. A description of the studied specimens, besides comments concerning its taxonomic status, the morphological characters
and measurements of the present material of
Monascus
sp. The
Monascus
sp. parasite are described on the present study compared
with some measurements of Nine nominal species have been reported in the genus
Monascus
up to 1993 and showing that similarity
with
M. filiformis
and differ in the size of parasite. The results indicated that the parasites are considered as having new hosts viz,
p.
argenteus
and as new records in the Iraqi marine fishes. In the present study, a new host and a new host locality are presented for the
two species. The taxonomic status of members of
Helicometrina
has been questionable, the validity of diagnostic features, especially
in regard to the number of testes. In the present study, specimens presented a permanent and steady number of testes (n=9) and
therefore its use as a diagnostic character and is very similar with Linton (1910).
Epinephelus tauvina
is considered a new host for
Helicometrina nimia
, and Northwest Arabian Gulf a new locality for the species.

Introduction
The Digenetic trematode represents the largest group of parasites as they comprise about 18,000 (Crib et al., 2001).
Family Fellodistomidae comprises to two subfamilies, Fellodistominae Nicoll 1909 and Haplocladinae Odhner
1911, which are composed of a large number of genera of small flukes. The type genus of the family was
described by Stafford in 1904 from the gall bladder of a Canadian wolf-fish,
Anarrhichas lupus
(Srivastava,
1935).
The fish fauna of the Arabian Gulf is highly enriched and nearly 500 species of bony as well as cartilaginous fish
were recorded from different coasts (Krupp and Muller, 1994)
. M. filiformis
is reported for the first time in the gut
of
Stromateus brasiliensis
of the south-western Atlantic Ocean (Luciana et al., 2015).
M. filiformis
had been
reported in
Pampus
(Stromateidae) from India (Sey et al., 2003), on
Cepola rubescens
(Cepolidae) from Italy, on
Selaroides leptolepis
(Carangidae) from Kuwait, on
Mugil ophuyseni
(Mugilidae) from China (Sey et al., 2003),
on
Trachurus trachurus
(Carangidae) from Denmark, Iberian Peninsula, Norway and Turkey (Køie, 1979; Lozano
et al., 2001; MacKenzie et al., 2004; Oguz and Bray, 2006) and, on
Trachurus lathami
(Carangidae) from
Venezuela (Nasir and Go´mez, 1977).
In the Atlantic Ocean,
M. filiformis
has been found only in five species of fish, Brazil:
Chloroscombrus chrysurus
(Carangidae) and
Trachurus lathami
(Carangidae) (Amato, 1982),
Oligoplites saurus
(Carangidae) (Travassos et
al., 1965; 1967),
Peprilus paru
(Stromateidae) (Wallet and Khon, 1987),
Micropogonias furnieri
(Sciaenidae)
(Pereira et al., 2000); and from cold temperate waters of Argentina it was reported infesting only
Trachurus
lathami
(Girola et al., 1992).
