3.3.1.3 Montistrongylus karungi (Figs. 3I–3K)

3.3.1.3.1 Synlophe (based on sections from four worms, sex not specified). Sections analyzed herein are those within proximal part of body: male (Fig. 2 /3I), and at midbody: male (Fig. 4 /3J) and female (Fig. 12/3K). In all sections lateral cords illustrated and ridges numbered in Figures 4 /3 J and 12/3K.

In all sections ridges irregularly spaced and grouped into two sets (set 1, set 2) alternating with two ridge-free spaces (arrowheads).

Within proximal body: in Figure 3I (male), 13 ridges; ridge set 1 situated on dorsal side, made up of eight small ridges, similar in size, irregularly spaced and oriented perpendicularly to body surface; ridge set 2 situated on mid-ventral side, made up of five small ridges regularly spaced with slight decreasing gradient in size from left to right and oriented from right to left.

At midbody: in Figure 3J (male), 17 ridges; set 1 situated on left side, made up of 11 small ridges (8’ to 1’ and 1 to 3) similar in size, except ridges ventrally adjacent to left lateral cord (4’ and 5’), slightly larger; most ridges oriented perpendicularly to body surface; only ridges 5’ and 4’ oriented from right to left; ridge set 2 situated on mid-right side, made up of six small ridges (4 to 9), similar in size, regularly spaced, without clear orientation.

Figure 3K (female): 11 ridges; ridge set 1 situated on left-ventral quadrant, made up of five small ridges regularly spaced, ridges ventrally adjacent to lateral cord (3’, 2’) larger and oriented from right to left, other ridges (6’-4’) smaller and oriented perpendicularly to body surface; ridge set 2 situated mainly on right-dorsal quadrant, extending to both mid-dorsal and mid-right sides, made up of seven small ridges (1’ and 1 to 6); ridges 1’, 5 and 6 apparently oriented from right-ventral to left dorsal-quadrant, remaining ridges (1 to 4) apparently perpendicular to body surface.

3.3.1.3.2 Bursa (number of worms studied not specified; illustrated in [35]: Figs. 7 and 11). Figure 7: dorsal ray and rays 8, dorsal view. Figure 11: bursa spread out, dorsal view. From the original written description [35]: bursa slightly dissymmetrical with right lobe larger and pattern of type 2-3 in both lobes.
