11. Parena latecincta species group

This species group contains four species distributed in East Asia, south slope of the Himalayan Range, north part of Indochina Peninsula, the Philippines, and northern Borneo. This group is characterized in the subgenus Parena by: postgenae without suborbital setae; elytra entirely metallic green or with metallic green lateral stripes; males with or without adhesive setae on ventral surface of mesotarsomere 1; male genitalia with stout median lobe, apical lamella thick in lateral view, apex not bent dorsally; endophallus with large flared basal expansion of primary sclerite; gonocoxite II of ovipositor slightly pointed near apical inner angle, ensiform setae grouped near apical angles. This species group is presumed to be close to the P. nigrolineata group for their similar general appearance, absence of suborbital setae, and similar features in gonocoxite II of ovipositor.
