Over all length 8 - 11mm. This species is shiny black with reddish shading in the female on each abdominal segment, whilst the male has one red band half way down the abdomen. The legs are reddish with dark knees. The wings have black patches on them. Apart from the wing venation the other thing that distinguishes Fold-winged Craneflies (Ptychopteromorpha) from the true Craneflies (Tipulomorpha) is the U-shaped suture on the top of the thorax. It is V-shaped in the Craneflies. This is shown well in the eighth picture below.
