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).
