Diagnosis. The new species, Proctophyllodes garrula sp. nov., belongs to the tricetratus species group. The males in this group are mainly characterized by the short aedeagus (not extending to the bases of terminal lamellae) and the reduced sclerotization of the central part of the opisthogastric shield (Atyeo & Braasch, 1966). Mironov et al. (2012) thought that this species group might be artificial, for the opisthogastric shield varied in this group, which were represented by one or two pairs of sclerites, or one unpaired genital fragment and two adanal fragments.

Within this group, the new species differs from other species by the following features: in male, the opisthogastric shield is separated into two anterior fragments and one unpaired posterior fragment, and the anal suckers have trapezoid-shaped accessory glands.

Etymology. The specific name, garrula (garrulus), derives from the generic name, garrulax, of the type host.
