Tanycranus elongatus Bartlett, 2010 – Bolivia, Brazil, French Guiana, Uruguay.

Recognition
This species is the only stenocranine currently known from South America. The very long head is similar to Frameus from Central America and Embolophora from Africa. In Tanycranus the apex of the head is truncate, the median carina of the frons is forked near the eyes, and segment 10 has 1 pair of processes. The form of the aedeagus is also distinctive. The drawing in Hamilton (2006, Figure 4) appears to be this species.
Molecular resources
There are no data on this genus in Genbank or BOLD.
