Fig. 2. Line drawings of Seussapex karybares gen. n. et sp. n. from Himantura uarnak 2 (sensu Naylor et al. 2012). A – whole worm;
scolex in fully protruded/evaginated state; B – scolex, in fully protruded/evaginated state; C – mature proglottid (subterminal) (arrowheads
indicate location of sections in Fig. 4A,B); D – detail of terminal genitalia.
Photomicrographs of whole-mounted scoleces at different stages of protrusion/evagination (top row) and corresponding histological
longitudinal sections (PAS-stained) (bottom row) of Seussapex karybares gen. n. et sp. n. from Himantura uarnak 2 (sensu Naylor
et al. 2012). Black arrowheads indicate boundary AMSP and AO. A – scolex in fully retracted/invaginated state; anterior glandular
compartment of AO (G1) surrounded by posterior glandular compartment (G2), both retracted to level of scolex proper; B – scolex with
partially evaginated anterior portion of AMSP and partially protruded posterior dome-shaped part of AO (black star indicates retracted
anterior knob-like part of AO); G1 surrounded by G2, both retracted to essentially level of AMSP; C – scolex with partially evaginated
anterior portion of AMSP and fully protruded posterior dome-shaped part of AO (black star indicates protruded/evaginated anterior
knob-like part of AO); G1 covering almost entire anterior of scolex surrounded by G2; D – scolex with evaginated anterior portion of
AMSP and protruded posterior dome-shaped part of AO (black star indicates invagined anterior knob-like part of AO); G1 covering
entire anterior of scolex, lying above flattened G2.
Scanning electron micrographs of Seussapex karybares gen. n. et sp. n. from Himantura uarnak 2 (sensu Naylor et al. 2012).
A – scolex in fully protruded/evaginated state showing scolex proper (SP) with suckers, posterior and anterior portion of apical modification
of scolex proper (AMSP), and posterior dome-shaped and anterior knob-like part of apical organ (AO); B – scolex in partially
protruded/evaginated state showing SP, posterior and anterior portion of AMSP, and posterior dome-shaped part of AO; anterior knoblike
part of AO retracted and/or invaginated into posterior part of AO; C – scolex in partially protruded/evaginated state showing SP,
posterior and anterior portion of AMSP, and anterior knob-like part of AO; posterior dome-shaped part of the AO retracted into AMSP;
D – acicular filitrich or microvilli on anterior knob-like part of AO; E – acicular to capilliform filitriches on posterior dome-shaped part
of AO; F – acicular to capilliform filitriches on anterior portion of AMSP; G – larger, hastate spinitriches and capilliform filitriches on
posterior portion of AMSP; H – small, hastate spinitriches and acicular filitriches on sucker; I – acicular filitriches on scolex proper at
level of suckers; J – capilliform filitriches on proglottid, increasing in length and diameter towards posterior margin of proglottid. Abbreviations:
AMSP – apical modification of scolex proper; AO – apical organ; SP – scolex proper. White arrowheads indicate boundary
between posterior and anterior portion of AMSP; black arrowheads indicate boundary between anterior portion of AMSP and posterior
part of AO. In A–C, small letters indicate location of details shown in the respective figure.
