Diagnosis. Within the genus, P. masinagudi Jaiswara , n. sp. can be recognized by the following characters: Epistemal suture slightly convex. Occiput with solid yellow band. Male. File shorter than P. kervasae Jaiswara , n. sp. Male genitalia as on Fig. 4 (D–F). Female. FW and HW length variable, extended upto 9th tergite or covering abdomen; HW longer than FW. Ovipositor slender and longer than both P. platycleis Bolívar, 1900 and P. kervasae Jaiswara , n. sp. (compare Fig. 3 B, F, G). Female subgenital plate long ( Fig. 2 O).

Description. In addition to the characters of the genus. Comparatively large species. 5th part of maxillary palpi concave on the dorsal side, 4th joint longer than 3rd and 5th. TI inner tympanum oval in shape; outer tympanum absent. HW slightly longer than FW in both male and female. TIII with 2 inner and 2 outer subapical spurs in males (2 inner and 2–3 outer in females), small and distal; no dorsal spine between subapical spurs; 25 inner in males (17–24 in females) and 25 outer in males (20–23 in females) spines above subapical spurs. Basitarsomeres III with 6 inner in males (6–8 in females) and 6 outer in males (6–8 in females) dorsal spines.

Male. FW and HW longer than abdomen. Harp divided by 7 transverse veins ( Fig. 2 L); mirror longer than wide, mirror angle more acute; diagonal vein with 1 veinlet connecting to file; stridulatory vein with 93 teeth. Supra anal plate with apically indented lobe ( Fig. 2 K). Subgenital plate wide and truncated apically ( Fig. 2 N)

Male genitalia. Pseudepiphallus transverse, 2 distal pseudepiphallic lophi separated by short wide sclerotized part; inner margin of lophi undulating and apically curled ( Fig. 4 D); base of lophi wide anteriorly. Ectophallic fold longer than P. kervasae Jaiswara , n. sp. ( Fig. 4 E), widely separated from pseudepiphallus and bent dorsally ( Fig. 4 F), thin like a spike, both side margins serrated, narrow base; a pair of sclerotized upper process or ectophallic hook fused posteriorly, half of the length of pseudepiphallic lophi ( Fig. 4 D). Endophallic cavity with a small triangular sclerite ( Fig. 4 E) anteriorly and an additional pair of long, parallel endophallic sclerite present ( Fig. 4 D). Long endophallic hooks present anteriorly with less wide base ( Fig. 4 E), hooks straight, thick and somewhat pointed apically, no additional long sclerites lateral to endophallic hooks. Rami long and disconnected anteriorly, posteriorly wide and concave making shallow cup like structure, attached to pseudepiphallic base ( Fig. 4 D).

Female. FW and HW length variable; FW with 3 anal veins, less curved; space between cubital and anal vein wide. FW slightly overlapping on its whole length, extended upto 9th tergite covering whole abdomen or extended slightly beyond. Subgenital plate semicircular and indented apically, longer than P. kervasae ( Fig. 2 O). Ovipositor long and narrow over its whole length ( Fig. 3 G)

Female genitalia. Copulatory papilla completely membranous, very flat and very faintly sclerotized (not figured).

Coloration. Face brown. Median ocellus sometimes encircled with thick yellow band or transverse yellow band present below it; lateral ocelli yellowish, connected by a thin yellowish line, extending upto head dorsum often faintly visible. Occiput with solid yellow band. Maxillary palpi mostly brownish with 5th joint yellowish apically. Cheek brown. Scapes brownish ( Fig. 3 E). FW dorsal field yellowish ( Fig. 1 E). FI & FII with brown dots; FII with a distinct subdistal brown ring; TII & TIII dorsally darker than TI; FIII with brown stripes on inner side; dark brown distally, and brown reticulation dorsally; TIII black brown basally, slightly darker distally. Female. FW veins less pigmented ( Fig. 1 E) than P. kervasae Jaiswara , n. sp.

Variation. One female has a spine between subapical spurs on inner side.
