In 1937, Yamaguti described a new parasite from a
Japanese fish and created a new genus
Lepocreadioides
for its reception. The genus, with
L.
zebrine
as the type species, was assigned to the
subfamily Lepocreadiinae Odhner, 5091 of the family
Allocreadiidae Stossich,1903.
Now the genus
Lepocreadioides
consists of nine valid
species (WoRM S, 2014). These are:
Lepocreadioides branchiostegi
Yamaguti, 1937
Lepocreadioides
cynoglossi
Fischthal, 1970
Lepocreadioides discumWang, 1986
Lepocreadioides huanghauensis
Qiu, Zang & Li, 1987
Lepocreadioides
interruptus
(Bilqees, 1973)
Lepocreadioides orientalis
Park, 1939
Lepocreadioides otolithi
(Bilqees, 1971)
Lepidocreadioides pagrosomi Wang
, 1982
Lepocreadioides
zebrini
Yamaguti, 1936
The excretory vesicles, winding between the testes,
seem to relate the specimens to the genus
Lepocreadioides
(Yamaguti, 1936). 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).
Lepocreadioides
however, has a cirrus
sac and a genital pore far to the left and far anterior.
L.
zebrini
Yamaguti, 1936 and
L. branchiostegi
Yamaguti,
1937 both have excretory vesicles extending anterior
to the acetabulum, but in
L. indicum
(Srivastava,
1941) ), which is a synonym of
L. orientalis
according
to WoRMS (2014), the vesicle extends only to the
ovary level (Manter, 1954).
According to Masaaki (2012) four new species of
family Lepocreadiidae were described from the
marine fishes of southern Japan and the Philippines,
one of them is
Lepidapedoides miharahanadai
from
the intestine of
Giganthias immaculatus
of southern
Japan.
Lepocreadioides orientalis
of the present study is
very similar to those of Park (1939) specimens while
Lepocreadioides
sp. is different in the site of the oral
sucker. The occurrence of these two species
represents their first record in the fishes of the
Arabian Gulf.
