Protanyderus vipio
Protanyderus vipio is a species of primitive crane fly in the family Tanyderidae. The genus Protanyderus contains some of the most archaic members of the Diptera, retaining characteristics that reflect the early evolutionary history of true flies. This species was described by Osten Sacken in 1877. Very few observations of this species exist in public databases, suggesting it is either genuinely rare, poorly surveyed, or restricted to specific habitats.
Protoplasa fitchii
Protoplasa fitchii is a species of primitive crane fly in the family Tanyderidae. It is one of the few North American representatives of this relict family, which retains many ancestral dipteran characteristics. The species is primarily known from eastern North America, where larvae develop in aquatic or semi-aquatic habitats. Adults are rarely encountered and poorly studied.
