3.7.1.1 Parvinema bafunminense ( Figs. 7A, 7B View Figure 7 )

3.7.1.1.1 Synlophe (Based on sections from six worms, sex not specified). Sections analyzed herein are at midbody: male (Fig. 18/7A) and female (Fig. 17/7B); lateral cords not illustrated; ridges numbered in Figure 18/7A.

In all sections, careen absent and axis of orientation of ridges described as oblique in [ 40].

Figure 7A View Figure 7 (male): dilatation of cuticle, evoking a careen, illustrated on left side; 16 ridges and two small gaps: one on right-ventral quadrant between ridges 9 and 7’, second one on left-ventral quadrant between ridges 3’ and 2’ (arrowheads); dorsal ridges regularly spaced and similar in size, except ridges 1 and 2, larger; ventral ridges regularly spaced, mid- ventral ones small (5’-3’) and right-ventral ones large (7’, 6’). Despite absence of illustration of lateral cords, tips of ridges oriented from right to left on both sides (dorsal and ventral) with ridge tips 1’ and 1 convergent (curved arrows on the left) and ridges 9 and 7’ divergent (curved arrows on the right), determining an axis of orientation oblique.

Figure 7B View Figure 7 (female): left ridge very large, strongly curved (inner curvature downwards); 16 ridges and a large gap on left-ventral quadrant (arrowhead); dorsal ridges irregularly spaced and dissimilar in size, median ones being shortest; ventral ridges mainly right-ventral, regularly spaced and large. On mid-right side, pair of divergent tips present and, immediately ventral, another pair of divergent ridges (curved arrows); dorsal and ventral ridges oriented from right to left.

3.7.1.1.2 Bursa (number of worms studied not specified, illustrated in [ 40]: Figs. 21, 25 and 26). Figure 21: distal part of dorsal ray and rays 8, orientation not specified. Figure 25: left lateral lobe, orientation not specified, only rays 3-6 illustrated, no link with left ray 8. Figure 26: right lateral lobe, orientation not specified, right ray 8 also illustrated. From the written description: bursa dissymmetrical with left lobe larger and pattern of type 1-3-1.
