mesosternum strongly declivous, ca.
Mesepisternum and
mesosternum orange; femora orange; extreme apex of hindfemur commonly blackish; tibiae and tarsii black.
Ventral coloration variable, usually in shades of shiny buff; some individuals greenish on head, pro- and
mesosternum; a dark brown ventromedian line extending longitudinally along the entire body except subgenital plate.
Pronotum with well developed two spines extending upto
mesosternum (Pro, meso and meta sternum with well developed spines two one on each side).
psidii presents
mesosternum plane between the middle coxae, the metastemum has the surface densely covered with coarse and deep punctures, the carina in the interval five disappears in the basal third and the humeri are rounded.
INTRODUCTION: The sternum consists of a cranial manubrium (Prosternum), an intermediate body (
