Pristiphora aphantoneura - Pristiphora ruficornis group
Males are unknown. This species cannot always be distinguished from Pristophora luteipes. The surface sculpture of the mesepisternum is not a reliable character. The lectotype has a yellowish-brown scape that is dorsally infuscate. The tegulae are black finely edged with yellowish-brown laterally. The pronotum is black. Separation of the two species is best achieved by detailed examination of the saw, though small differences in the hypopygium may also be diagnostic.
Pristiphora aphantoneura larvae feed on meadow vetchling.
Size: 3.7 - 5.5mm
