FIGURES 11–14 in The deep-sea fish digenean genus Tellervotrema Gibson & Bray, 1982 (Opecoelidae: Plagioporinae): Re-evaluation of the type species, T. armstrongi Gibson & Bray, 1982 and T. beringi (Mamaev, 1965)

FIGURES 11–14. Variability in number, symmetry and location of vitelline gap(s) in Tellervotrema beringi (Mamaev, 1965) from the giant grenadier, Albatrossia pectoralis. 11. Ventral view of horizontally symmetrical gaps (2; gaps indicated by arrows) at about level of posterior margin of ventral sucker producing Tellervotrema-like, paired, isolated, anterior vitelline groups. 12. Ventral view of 1 gap, located on left side at level of posterior margin of ventral sucker; no gap on right side. 13. Dorsal view of diagonally symmetrical gaps (2) at level of ventral sucker. 14. Ventral view of asymmetrical gaps (2) located oblique to ventral sucker; complete horizontal gap on right side (arrow) and incomplete gap on left side with medially-displaced vitelline follicles (bar). Abbreviations: C, cecum; O, oesophagus; V, vitelline follicles; VS, ventral sucker. Scale-bars: 11, 490 µm; 12, 575 µm; 13, 640 µm; 14, 500 µm.
