His diagrams support our conclusions in the above description, including the fusion of the aedeagal sclerites with the surrounding ectophallic sheath, and the connections between the arch and the cingular rami.
Each segment (A1-A7) divided into three subsegments separated by transverse depressions; spiracle located laterally on dorsum of second subsegment; second, third subsegments separated by pronounced depression bearing pair of clear sublateral sclerites.

All statements of sclerite position refer to the unexpanded left bulb from its ventral view.
trichiuri by presenting eight genital spines (six of them larger and two smaller), by differences in the shape of the inner and outer pairs of hooks, in the testes distribution, by the larger number of testes, and by the larger sclerite c, as well as the largest association of the sclerite b3 with the fair-lead.
Dondersiidae comprises nine genera and 32 species (Table 1) on the basis of a thin cuticle without skeletal sclerites or epidermal papillae (not unique to this family), and by varying combinations of characters: body with or without posterior end drawn out into fingerlike projection; with two or more types of raised (not adpressed) solid sclerites or one type of adpressed scales; radula monostichous with two or more denticles per row, the central two fused or not fused distally, or radula lacking; ventrolateral foregut glands as groups of extraepithelial unicellular gland cells ("follicles") or as multicellular glands ("type A"); and with or without copulatory spicules.

The sparse behavioral data suggest that copulating males typically first produce a mating plug consisting of the distal two palpal sclerites stuck in the female reproductive apparatus (epigynum), thereby preventing additional access to the used female copulatory opening by rival males.
