Haptor ventral and well separated from body proper. Oral suckers separated, and pharynx suckers smaller than the buccal suckers ( Fig. 3b ). Copulatory organ consists of a central muscular pad with 10 (may vary) median smaller genital hooks and two muscular pads anterolaterally, each with a single curved large hook ( Fig. 3c ). Terminal lappet contains one pair of anchors and one pair of marginals. Large shape and structure of anchors also differ from other Kuhnia species being distinctly hook-like at posterior end and forked anteriorly ( Fig. 3f ). Haptor containing two approximately parallel rows of clamps of equal size with four clamps in each row. Caeca terminating at the level of the posterior part of the haptor. Species contains two dorsolateral vaginas, or two vaginal cavities (posterior to gonopore) supported by numerous transverse ridges.
