Fig. 5. Clestobothrium cristinae sp. n. from Merluccius hubbsi. A- scolex showing contracted U-shaped muscular sphincter; dorsoventral
view, holotype (MACN-Pa 511/1); B - scolex relaxed showing musculature of bothria; dorsoventral view, paratype (MACNPa
511/2); C - mature proglottides; vitelline follicles only illustrated in posterior proglottis; osmoregulatory canals not illustrated;
dorsal view, holotype (MACN-Pa 511/1); D- eggs with operculum; E - transverse cross-section of mature proglottis at level of genital
pore; paratype (MACN-Pa 511/2); F - transverse cross-section of mature proglottis at level of ovary; paratype (MACN-Pa 511/2).
Abbreviations: cs - cirrus-sac; gp - genital pore; lm - bundles of longitudinal musculature; msp - muscular sphincter; nc - nerve
cord; nm -narrow muscle; oc - osmoregulatory canals; op - operculum; ov - ovary; sa - spurious articulation; t - testes; up - uterine
pore; ut - uterus; of - vitelline follicles; vg - vagina. Scale bars: A-D = 500 µm; E, F = 250 µm.
B - Clestobothrium cristinae sp. n., paratype (IPCAS
C-601) from Merluccius hubbsi showing osmoregulatory canals, irregularly alternating cirrus-sac and vitelline follicles in dorsal
view; two last pieces of strobila showing uterine sac in ventral view. Abbreviations: gpr - gravid proglottides; mpr - mature proglottides;
msp - muscular sphincter; nm - narrow muscle; oc - osmoregulatory canals. Scale bars = 500 µm.

showing tumuli; letters B, C indicate surfaces shown at high magnification in B, C; B - central surface between lips; C - marginal
surface of lips; D - piece of immature strobila; E - surface of middle and posterior part of immature proglottis; F - piece of
mature strobila showing position of genital pore relative to spurious articulation (white arrows), dorsal view; G - piece of gravid
