Abstract
During the investigation of
Psettodes erumei
and
Sillago sihama
two different parasites were detected
Lepocreadioides
orientalis
Park,1939
and
Lepocreadioides
sp. Fish specimens were collected from the Arabian Gulf during the year 2013. The results
indicated that these two parasites are considered as having new hosts viz,
P. erumei
and
S. sihama
and as new records in the Iraqi
marine fishes.

Introduction
Digenetic trematodes represent the largest group of all
internal metazoan parasites as they comprise about
18,000 nominal species (Cribb et al., 2001). The
suborder Hemiurata is one of the most diverse groups
of digeneans which usually occurs in the stomach and
intestine of mainly marine teleost fishes (Gibson and
Bray, 1979). This group has a wide geographical
distribution, being found in the Great Barrier Reef of
Australia, the Indian Ocean, and the Atlantic Ocean
(Gibson and Bray, 1986). Life cycle of hemiuratids
typically has marine gastropods as first intermediate
hosts, crustaceans or some other invertebrates as second
intermediate hosts and fishes as final hosts (Køie, 1979).
Members of Lepocreadiidae are recognizable as
worms with widely distributed vitelline follicles,
aspinous tegument, usually with a distinct external
seminal vesicle and a typically I– shaped excretory
vesicle (Bray, 2005).
The Lepocreadiidae fauna of the Arabian Gulf and the
Iraq marine water is reported and discussed and a new
host and locality records are presented, New host and
locality records and a description were given of
Lepocreadioides
sp 1 and
Lepocreadioides
sp2 in
Synaptura orinetalis
by Bannai (2002) and new hosts
and locality records of
Lepocreadioides
zebrini
in
Brachirus orientalis
by (Bagherpour et al., 2011).
Material and Methods
Monthly fish samples were collected from Khor
Abdullah, north west of the Arabian Gulf, from March
to October 2013. A Total of 20 fish specimens of the
two species were collected.
These fishes were kept in ice box and brought to the
laboratory. The methods and techniques used for
collection, relaxation, fixation, staining and
mounting of helminthes are basically those described
by Roberts (2001). Fishes were examined only for
internal parasites, the abdominal cavity of each fish
was opened and the intestine was separated from the
other visceral organs and placed in a Petri-dish
containing physiological saline and examined for
parasites. The parasites were washed in a 0.6% saline
solution and fixed in 70% ethanol. They were stained
with alum carmine, dehydrated and then cleaned in
xylene and mounted in Canada balsam. Drawings
were prepared by camera Lucida.
The specimens
were deposited in the Department of Aquaculture and
Marine Fisheries, Marine Science Center,University
of Basrah, Iraq. Parasites identification was done
with the aid of Yamaguti (1971).
