Bothriocephalus timii n. sp. is the first
tapeworm species reported from a bovichtid fish. The
new species was commonly found (prevalence 85%)
in the intestine of Cottoperca gobio (Gu¨nther) collected
on the Patagonian shelf off Argentina. It is
characterised by a strobila with segments and proglottides
usually longer than wide, having posterolateral
wing-like expansions with a medial notch on both the
dorsal and ventral surfaces; a scolex with an apical
disk; elongate bothria opening posteriorly, with laterally
and longitudinally extended convex lappets; testes
42–185 in number, in one layer, arranged in two lateral
continuous bands along the strobila; an elongate
cirrus-sac, situated obliquely, with the proximal part
curved anteriolaterally; and an ovary which is usually
butterfly-shaped. The new species is morphologically
similar to B. bengalensis Devi, 1975 from Carangoides
plagiotaeniata Bleeker, B. branchiostegi
Yamaguti, 1952 from Branchiostegus japonicus Houttuyn,
B. carangis Yamaguti, 1968 from C. ferdau
Forsska°l and B. gadellus Blend & Dronen, 2003 from
Gadella imberbis (Vaillant) based on the presence of
posterolateral wing-like expansions with a medial
notch on dorsal and ventral surfaces of segments and
proglottides along the strobila. Bothriocephalus timii
n. sp. differs from B. bengalensis, B. branchiostegi and
B. carangis in the absence of a vaginal sphincter and
from B. gadellus in the number of testes and the size of
scolex. Unpublished molecular data suggest that B.
timii is most closely related to B. australis Kuchta,
Scholz & Justine, 2009 from Platycephalus spp. and B.
scorpii (Mu¨ller, 1776) from Myoxocephalus scorpius
(Linnaeus). The genus Indobothrium Sedova &
Gulyaev, 2009 is herein considered a junior synonym
of Bothriocephalus Rudolphi, 1808.
