The holotypic male is 185 µm long. Orientation of the preparation prevented estimating the maximum width, however, the height is 78 µm between the second and third leg pair, measured on the outer epicuticle. The body is thin and elongate with the typical bell-shaped outer epicuticle surrounding the trunk (Fig. 16A; allotypic female. Fig. 16E; holotypic male). Internal epicuticle with numerous well developed pillars (Fig. 15).

The 13 µm internal cirrus is similar to the median cirrus; however, the transition between scapus and flagellum is more marked in the median cirrus. The 23 µm external cirrus is surrounded by the secondary clava. The 23 µm lateral cirrus is situated close to the primary clava and the two structures share an indistinct common cirrophore and are partially enclosed in a funnel-shaped epicuticular fold. The 6.5 µm short ovoid primary clava has a distinct “van der Land’s organ”. The enlarged secondary clava surrounds the external cirrus nearly closing on itself (Fig. 16B; allotypic female). The epicuticular pillars surrounding the secondary clava are very refractive. No eye spots were observed.</paragraph>

The stylets are 31 µm long. The long and thin stylet supports (8 µm) articulate with the furcae (Fig. 16C; allotypic female). Stylet sheaths cover half the length of the stylet. The placoids consist only of a cuticular lining and three small calcified apodemes can be observed in the anterior part of the pharyngeal bulb.</paragraph>
