Figures 11–13

Diagnosis: This species is most similar to P. punjabica from India. It is distinguished from Pt. punjabica in having rounded cerci; its paraproctal complex has downward-curving dorsal paraproctal processes (not upward directed); its gonopods each have a spiny and mesad-curving apical half and a larger basal dorsomesal process.

Description: Male. Body uniformly brown. Maxillary palp formula (I,II)-IV-III-V, 3rd segment of each maxillary palp inserted subapically on subapicolateral surface of 2 nd segment. Forewings brown, with length 6.0 mm. Discoidal cell closed in each forewing and hind wing; forewings each with median cell closed and with apical forks 1, 2, 3, 4, and 5; hind wings each with apical forks 1, 2, and 5.

Male genitalia. Sternite IX subtriangular, with concave ventral margin in lateral view ( Fig. 11 ); dorsoapical part connecting to sternite and to fulcrum formed by cerci and paraproctal complex. Tergite IX membranous, visible at fulcrum, connecting dorsally produced angles of sternite IX to cercal and paraproctal complexes. Segment X forming membranous roof projecting posterad in continuation of dorsoapical corner of sternite IX and tergite IX. Setose, rounded cerci arising from paraproctal body. Paraproctal complex fused to cerci and modified to form lateral and ventral phallic guide; dorsal paraproctal processes each dominating, forming large, downward-curving spine with small, dorsal subapical setose area. Ventral paraproctal processes rounded, each forming vertical plate with row of setae on apical margin. Gonopods simple, straight, horizontal and arching slightly upward, narrowing in lateral view, with spine-shaped apical half curved mesad in ventral view ( Fig. 12 ); basal dorsomesal process weakly capitate in lateral view ( Fig. 11 ), directed mesad in ventral view and armed with short black teeth. Phallic apparatus ( Fig. 13 ) broad, horizontal, fixed; sclerotized phallotheca with short phallobase and wide ventral foramen; phallotremal sclerite with indefinite shape, located in middle of retracted endotheca.

Holotype male: MYANMAR: S. Shan States , road 40 km E. Taunggyi, 13.x.1934 [R. Malaise]— ( BMNH, Coll. Malaise, B.M. 1938-258).

Distribution: Myanmar.

Etymology: Taungyia, named after the type locality near Taunggyi.
