Figs 1–5 , 20

Diagnosis

Larger-sized species (forewing length: 34.5–44.8 mm), superficially resembling to Baliga sagax (Walker, 1853) based on similar yellow markings on vertex but can be distinguished by the yellow pronotum, with a pair of well separated median longitudinal dark brown stripes and frons mostly shining black, but medially with a narrow longitudinal yellow marking and a narrow median U-shaped yellow marking at ventral corner ( Fig. 3B–D ).

Etymology

The new species is named after its type locality, i.e., Azad Kashmir, Pakistan.

Forewing: relatively broad, subacute at apex; membrane hyaline; longitudinal veins dark brown, except Sc with alternate dark brown and yellow patches, covered with sparse short black setae; costal area with interconnected crossveins proximal to pterostigma for at least ⅓ of forewing length; seven to nine presectoral crossveins; initial branching point of CuA at same level to Rs origin; Rs with 12–16 branches; pterostigma milky white; anterior Banksian line absent; posterior Banksian line present. Hind wing: slightly longer than forewing, acutely pointed at apex; membrane hyaline; longitudinal veins dark brown, except Sc with alternate dark brown and yellow patches, covered with sparse short black setae; costal veinlets simple, except a few marginally forked crossveins around poststigmal area; five presectoral crossveins; median fork proximal to Rs origin; Rs with 14–18 branches; pterostigma milky white, relatively smaller than that on forewing; anterior Banksian line absent; posterior Banksian line present; pilula axillaris with rounded knob, covered with dense brown setae.

ABDOMEN ( Fig. 1 ). Tergites brownish, covered with short brownish yellow setae. Sterites brownish yellow, covered with short brownish yellow setae.

MALE GENITALIA ( Fig. 4C–G ). Tergum 9 trapezoidal, with anterior margin slightly prominent in lateral view.
