Representation of transversal cuts on specimens of Luteostriata abundans at different body regions. Horizontal lines represent the point at which a transversal cut was performed. Ellipsis with a continuous outline represents the location of the mouth and ellipsis with a dashed line represents the location of the gonopore. AE: anterior end; AE-M: anterior end plus mouth; AE-MG: anterior end plus mouth and gonopore; G-PE: posterior end plus gonopore; MG-PE: posterior end plus mouth and gonopore; PE: posterior end.
