Diagnosis: 
Males of this species have short, narrow hypovalves that only extend about 2/3 the length of the basistyles and are cleft almost to the base of the 9th sternite medially.   There are stiff bristles along the medial edge of each hypovalve.  The ventral parameres are thin and unbranched and reach to the basal lobe of the dististyles.  The dorsal valves are also elongate and narrow but reach only to the base of the dististyles.  There is a dark medial spot at the base of the eadeagus between the dorsal valves.  Female subgenital plate is quite elongate and narrow, without an apical notch.
