(Fig. 3, 17, 31, 45, 60, 76, 77 & 102)
Diagnosis. Head and pronotum green with metallic lustre. Elytral fasciae co mma shaped located at 1/3rd from apex extending from 3rd interval (only touching) to 8th which descends and reaches apex; intervals densely punctate pubescent; pronotum quadrate, moderately punctate and pubescent, punctures more in basal region; apical margin of labrum almost truncate; median tooth of mentum quadrate with rounded angles; last segment of maxillary and labial palpi conical; lamella of aedeagus rounded at apex, left side of median lobe expand laterally on dorsal view.
Description. BL = 12.26 mm, HW= 2.24 mm, PL= 2.32 mm, PW= 3.46 mm, EL= 7.34 mm, EW= 3.96 mm
Head and pronotum green with metallic lustre, lateral margins of pronotum brown; elytra green with metallic lustre same as pronotum but seems darker due to pubescence. Labrum, mandibles and coxae dark brown; trochanters, labial and maxillary palpi brown; first three antennomeres, maxillary palpi, labial palpi and tarsomeres light brown; remaining antennomeres darker due to pubescence; femur, tibia yellowish brown.
Head surface finely punctate, with depressed lines near eyes. Labrum almost truncate with rounded apical angles, fine setae present on either side; clypeus truncate. Last segment of maxillary and labial palpi somewhat conical and dorsoventrally flattened, truncate at apex, slightly compressed towards apex. Median tooth of mentum quadrate with rounded angles.
Pronotum a little convex, quadrate, wider than long, basal margin wider than apical margin, apical margin emarginate, basal margin almost straight; basal angles obtuse but not sharp. Surface moderately punctate and punctures larger than that on head disk, broader at basis and the fovea, punctures with yellowish pubescence. Median line prominent without reaching extremities.
Elytra striate punctate, intervals densely punctate pubescent; fascia on elytra comma shaped located at 1/3rd from apex extending from 3rd interval (only touching) to 8th which descends and reaches apex.
Prosternum coarsely punctate, proepisternum sparsely punctate, almost glabrous laterally, prosternal process bordered; mesosternum almost impunctate, mesepisternum coarsely but sparsely punctate; metasternum coarsely but sparsely punctate medially, densely punctate laterally, metepisterna with very few punctures. Abdominal sternites glabrous, with fine punctures, lateral sides with wrinkles.
Aedeagus stout; apical lamella rounded at apex, bent ventrally and twisted, length of apical portion very short; left side of median lobe expand laterally on dorsal view.
