An analysis of thePsaironeura tenuissima complex , including synonymy of

WILLIAMSON (1915) proposed the genus Psaironeura to contain Protoneura remissa Calvert and his newly described species, P. cerasina. Since then, six names have been placed underthis genus.Psaironeuraremissa and P. selvatica Esquivel are largely dark metallic green species from Central America whose malespossess broadly foliate cerci in lateral view. A third undescribed species similar to P. remissa is known from Panama, Venezuela,Colombia and Ecuador. The other four names have been applied to a series of entirely South American specimens, whose males possess semicircular cerci and are pale (thorax mostly red in life). The latter species names are the subject of this paper. SELYS (1886) describedProtoneura tenuissimafrom at leasttwo pairs from “Pebas, Teffe (Amazone). Coll. Selys.”of which a lectotype was selected by MACHADO (1985). WILLIAMSON(1915) described Psaironeuracerasina from one malefrom Wismar, British Guiana. He described this species in life as “a delicate and beautiful insect, the
