Bursa characterised by papillae 2 (ventral) very close (45–50 μm) to each other (Fig. +1 C +), implying that lobes were studied separately because spreading out the bursa would break them. Right lobe (Fig. +1 D +): pattern of +type +1-4, with ray 2 arising first from long common trunk of rays 3–6. Ray 3 arising at mid-length of common trunk, but distance between papillae 2 and 3 larger than that between papillae 3 and 4. Rays 4–6 diverging nearly at same level at distal quarter of common trunk, forming the characteristic “ lateral trident ”. Ray 6 curved posteriorly, may be slightly longer than rays 4 and 5. Rays 3, 4, 5, and 6 reaching bursal margin. Left lobe (Fig. +1 E +): pattern of +type +2-2 - 1. Rays 2 and 3 diverging in ‟ +V +” proximally. Very short common trunk of rays 4–6, with rays 3 and 6 diverging at same level. Rays 4 and 5 diverging last. All rays reach bursal margin. Distance between papillae 2 and 3 slightly larger than that between papillae 5 and 6. Papillae 3, 4, and 5 approximately equidistant from each other. Rays 2 thickest and 6 thinnest. Dorsal lobe well developed, displaced to the left, compensating the reduced size of left lobe. Dorsal ray very long, divided at about its distal quarter into two branches, each one bifurcated distally into two papillae, external rays 9 and internal rays 10. Arising and path of rays 8 markedly dissymmetrical (Fig. +1 F +). Left ray 8 arising proximally from dorsal ray, nearly at its base; then running close and parallel to left trunk, approaching to and ending near left papilla 6. Right ray 8 arising more distally on dorsal ray, at about its proximal quarter, running between right trunk and dorsal ray, then heading distally towards right ray 6 but ending far from it. Genital cone long, well developed, bulbous at base, strongly curved ventrally in distal part. Distal half of cone with sclerotised walls.
