The Capsalinae is a subfamily of 60 monogenean
parasite species which live primarily on the skin and
gills of highly-prized game fish. Members of the
Capsalinae can be distinguished from other capsalids
by the presence of a septate haptor, a single pair of
haptoral accessory sclerites and multiple testes
(Whittington 2004). Diagnostic characters of this
genus are the two neighboring groups of testes, and
the structure of loculi of the Haptor, these characters
were confirmed by Ergorova (1994) in her revision of
Trochopodinae.
The Capsalidae fauna of Arabian Gulf and Iraq marine
water is reported and discussed and a new host and
locality records presented. New host and locality
records and a description are given of Monogenea of
Arabian Gulf fishes by Kardousha 2002, Descriptions
of three
Capsala
spp. (Capsalidae) including
Capsala
naffari
n. sp. infecting mackerel tuna
Euthynnus
affinis
from coasts of Emirates. Three species of the
genus
Capsala
including
Capsala
naffari
n. sp.,
C.
neothunni
(Yamaguti, 1968) and
C. nozawae
(Goto,
1894) are recorded and described from the buccal
cavity of mackerel tuna
Euthynnus affinis
caught from
Emirate coasts.
Capsala naffari
can be differentiated
by its lateral spiniform teeth, which extend posteriorly,
small measurements compared with the closely
resembled
C. gotoi
and relatively large testes.
1 Material and methods
Monthly fish samples were collected from Khor
Abdullah, north west of the Arabian Gulf, from March
of the year 2014. A Total of five fish specimens 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 measured 40 – 46.0 cm of
total length, and weighted 5kg. All the Monogenea
parasites were fixed in A.F.A., preserved in ethanol
70°GL, stained with Gomori’s trichrome, and
mounted in Canada balsam. Measurements were made
in micrometers. Parasites identification according
Yamaguti, 1968 and Ian D. Whittington, 2004).
Drawings were prepared by Camera Lucida.
2 Result and Discussion
During a parasitological survey of marine fishes from
the coastal zone of the Iraqi marine water.
Sprostoniella
teira
. was found on the gill filaments of
Platax teira
specimens (Figure 1).
