Description: Laura's Clubtail is a large species at 2.3 inches long. The face is pale with two dark cross-bars and green eyes. The thorax has yellow stripes on the front which are not collected to the yellow collar. The abdomen is black grading into brown towards the posterior end. There is a pale dorsal stripe on the abdomen and small basal spots on the base of the sides of S3 - S6. The club part of the abdomen has wider yellow markings on its sides. The legs are brown with some yellow in the females.

The Riverine Clubtail (Stylurus amnicola) is smaller and has distinctive frontal thorax markings.
