Diagnosis. The new species, Proctophyllodes brevis sp. nov., belongs to the pinnatus species group. In all of species of this group, the male pregenital apodeme is absent, the genital sheath supported basally by a strongly sclerotized ring, anal suckers circular; adanal accessory glands are absent, and the opisthogastric setae in trapezoidal arrangement and inserted on connected shields (Atyeo & Braasch, 1966). Within this group, the new species is related to P. troncatus Robin, 1877 from Passer montanus (Linnaeus, 1758) (Passeridae) by having the similar shape of the opisthogastric shield. In males of P. brevis sp. nov., the base of setae h2 are expanded, and the anal suckers are about 17–21 in length and 16–18 in width. In males of P. troncatus , the shape of setae h2 is normal, and the anal suckers are 21 in length and 10 in width. And in females, all type materials of P. brevis sp. nov. have fully developed terminal appendages, whereas P. troncatus rarely has fully developed terminal appendages.

Etymology. The specific name is derived from Latin word, brevis , which refers to the anal suckers in male is short.
