1916. Togotipula Matsumura; Thous. Ins. Japan, Addit. 2:465. 



A small genus, including about a dozen species in the eastern 

 Nearctic, southern Ethiopian and eastern Palearctic regions. One 

 of the local species, testaceus, is the largest crane-fly in the fauna. 

 The adult flies occur near rapidly-flowing woodland streams. The 

 larvae are aquatic, living in sand or gravel in the stream-bed. or, 

 more rarely, in saturated submerged wood. The Nearctic species, 

 including the genotype, testacevs, have the squamae naked and the 

 tibiae without spurs.
