‘l'ype in the collection of the Paris Museum. . 
‘This beautiful crane-fly is readily told from all described 
African Tipulinee by the beautifully dimidiate wings. The 
claws bear a small, acute, ventral tooth that is only visible 
when the foot is viewed from the side. The presence of this 
tooth would indicate that this fly isa male. This interesting 
species is named in honour of its collector.
