3.3.2.3 Montistrongylus karungi

3.3.2.3.1 Synlophe. The descriptions of the three sections of M. karungi ( Figs. 3I, 3J, 3K View Figure 3 ) are similar with those of the male sections of M. ingati ( Figs. 3A, 3C View Figure 3 ): two sets of ridges alternating with two ridge-free spaces. The orientation of the axis remains uncertain, many ridges being oriented perpendicularly to body surface. However, the position of the ridge sets and ridge-free spaces differ between the three sections.

The proximal section of a male ( Fig. 3I View Figure 3 ) has been deformed during fixation, and the body itself, limited by the hypodermis is not at its correct place. If we displace the body inside the cuticle ( Fig. 3I’ View Figure 3 ), we obtain a section in which the position of the ridges and the ridge sets is very similar with the section of the female at midbody. In addition, the number of ridges in the two sections is similar (11 vs. 13) as opposed to 17 for the section of a male at midbody.

This latter section is closely related to the section of a male of M. ingati at midbody: same position of the sets, 15 ridges in M. ingati , 17 in M. karungi .

3.3.2.3.2 Bursa. From the illustration, the bursa is of type 1-4 in both lobes; rays 3 diverging from a common trunk at the same level as ray 6 in the right lobe and proximally to it in the left lobe. Right ray 6 diverges first from the common trunk 4-6 in right lobe, at about same level in the left lobe. There are clearly two different types of dorsal lobes which means that there are probably two different taxa among the males studied.
