FIGURES 1-5. Tylocephalum brooksi n. sp. 1. Complete worm. 2. Detail of scolex. 3. Detail genetalia terminal, note internal seminal vesicle. 4. Mature segment, ventral view. 5. Mature segment ventral view, note the vulominous external seminal vesicle, becoming larger as segments mature and testes degenerate. Vitellaria are circummedullary in Figure 4 but are only partially drawn to allow the view of internal organs. 
FIGURES 6-11. Tylocephalum brooksi n. sp. 6. Scolex, general view, scale bar = 100 µm. 7. Detail of collar between pars apicalis and pars basalis, note large digitifomr processes, scale bar = 20 µm. 8. Distirbution of microtriches along the collar, scale bar = 5 µm. 9. Details of large digitiform processes covering collar, sclae bar = 1 µm. 10. Short filiform microtriches on pars basalis surface, scale bar = 1 µm. 11. Short filiform microtriches on neck surface, scale bar = 1 µm. Best viewed in Firefox
