Discussion. Differential diagnosis. Related to L. excelsus here described from Peru ( Figs. 17 , 57 ). This species is caracterized by having the humeral angles rounded, the apex of scutellum yellow, the anterior and posterior lobe of metathoracic peritreme dark brown and abdominal sterna III–VI included the rim of abdominal spiracle reddish brown. In L. halatus sp. nov., ( Figs. 17 , 57 ), described from Brazil the humeral angles are rounded with tiny spiny projection, the apex of scutellum black, the anterior and posterior lobe of metathoracic peritreme, and abdominal sterna III–VI included the rim of abdominal spiracles yellowish orange.
