Mimobdella Blanchard, 1897

Type species.

Mimobdella japonica Blanchard, 1897

Emended diagnosis.

Mid-body somites novem-annulate, c1 = c2 <b2 <a2> c9 = c10 = d21 = d22 <c12. Post-anal annulus present. Pharynx strepsilaematous, with three myognaths separated by triangular papragnaths; each myognath bearing stylets in pairs arranged in tandem. Testisacs multiple. Accessory copulatory pit and gastopore absent.

Remarks.

Sawyer (1986) placed three species, Mimobdella japonica , Mimobdella buttikoferi Blanchard, 1897, and Mimobdella thienemani Augener, 1931, under the genus Mimobdella . However, Blanchard (1897) described that Mimobdella buttikoferi does not possess paragnaths (pseudognaths in his paper). Augener (1931) described that the mid-body somites annulation of Mimobdella thienemani is sexannulate (two large and four short annuli). Their external features do not match the generic diagnostic characters according to the type species. In addition, the internal morphology of the two species has not been reported. Thus, it is questionable whether those two species, Mimobdella buttikoferi and Mimobdella thienemani , belong to this genus. Therefore, only one species, Mimobdella japonica , is certainly included in Mimobdella .
