Etymology. Species named after type locality.

Diagnosis. Within the genus, P. kervasae Jaiswara , n. sp. can be recognized by the following characters: Epistemal suture almost straight ( Fig. 3 C). Male genitalia as on Fig. 4 (A–C). FW and HW much longer than abdomen. Female. Ovipositor almost of the length of P. platycleis but narrower; curved dorsally from middle of its length (compare Fig. 3 B, F). Female subgenital plate ( Fig. 2 J) narrower than in P. masinagudi Jaiswara , n. sp. ( Fig. 2 O).

Coloration. Bulged area between antennal pit and epistemal suture with two yellow dots ( Fig. 3 C). Clypeus with two vertical yellow lines; labrum with two yellow dots ( Fig. 3 C). Cheek brown, yellow line on dorsal margin underlying eye; with a yellow dot close to the mandibula and one close to the eye ( Fig. 3 C, D).

Description. In addition to the characters of the genus. Comparatively smaller than P. platycleis . 5th joint of maxillary palpi concave on the dorsal side, 4th joint slightly longer than 3rd and 5th. TI inner tympanum oval in shape; outer tympanum absent. FW and HW much longer than abdomen; HW slightly longer than FW in both males and females. TIII with 2 inner and 3 outer subapical spurs, small and distal; no dorsal spine between subapical spurs; 20–24 inner and 20–22 outer spines in males (19 inner and 18 outer spines in females) above subapical spurs. Basitarsomeres III with 8 inner and 7 outer dorsal spines in males (7–8 inner and 7–8 outer spines in females), in addition to apical ones.

Male. FW and HW longer than abdomen. FW: Harp divided by 6–7 transverse veins ( Fig. 1 B, 2E); mirror almost as wide as long, mirror angle more obtuse; diagonal vein with 2 veinlets connecting to 1st anal vein; stridulatory vein with 137 teeth. Supra anal plate with a pair of hooks ( Fig. 2 G). Subgenital plate narrow and apically more pointed ( Fig. 2 H).

Male genitalia. Pseudepiphallus transverse, 2 distal pseudepiphallic lophi separated by long and thin sclerotized part; inner side of distal lophi concave and serrated; base of lophi narrow anteriorly ( Fig. 4 A). Ectophallic fold very long, wide anteriorly and narrow posteriorly, very much like an arrow ( Fig. 4 B); posteriorly ectophallic fold with lines of small denticles ( Fig. 4 C); a pair of short sclerotized upper process associated with the ectophallic fold. Endophallic cavity with a more or less oval sclerite ( Fig. 4 B) anteriorly and an additional pair of thick, long, parallel, endophallic sclerites, bifurcated anteriorly ( Fig. 4 B). Long endophallic hooks present anteriorly with very wide base ( Fig. 4 B); hooks curved, thick and pointed apically, additional long sclerites lateral to endophallic hooks present ( Fig. 4 B). Rami long and disconnected anteriorly, posteriorly thin, bent facing each other and apical ends bent further down ( Fig. 4 A).

Female. FW with 2 anal veins and many irregular transverse veins, space between anal and cubital vein less. FW slightly overlapping on its whole length, extending beyond abdomen covering half of the ovipositor ( Fig. 3 F). Ovipositor longer than TIII; relatively narrow over its whole length ( Fig. 3 F). Subgenital plate shorter ( Fig. 2 J).

Female genitalia. Copulatory papilla flat, partly membranous, with a pair of distinctively sclerotized asymmetrical structures, connected basally with faint sclerotization; opening of spermathecal duct sclerotized dorsally; ventrally copulatory papilla more triangular in shape ( Fig. 2 I).

Coloration. Face brown ( Fig. 3 C). No transverse yellowish band at the level of median ocellus; yellow dot below median ocellus and sometimes above; lateral ocelli yellowish, connected by a thin, yellowish line. Maxillary palpi mostly brownish with 5th joint yellowish apically. Cheek brown, yellow line on dorsal margin underlying eye; with a yellow dot close to the mandibula and one close to the eye ( Fig. 3 D). Bulged area between antennal pit and epistemal suture with two yellow dots ( Fig. 3 C). Clypeus with two vertical yellow lines; labrum with two yellow dots ( Fig. 3 C). Scapes yellowish, with brown outer margin. LL dark brown. DD brown. FW dorsal field light yellow. Legs yellowish; FI, FII with a subdistal brown ring; TI, TII, TIII darker dorsally; FIII with brown stripes on inner side; dark brown distally, and brown reticulation dorsally; TIII black brown basally, slightly darker distally. Female. FW veins darker than P. masinagudi Jaiswara , n. sp. ( Fig. 1 C).
