Diagnosis: Large species. Third antennal segment obtuse. Surstyli small compared to postabdomen; epandrium very short; ST8 large, m.a. occupies all of ST8, except upper left angle. SES enlarged, with a wide lobe at the end; phallic guide long, with a groove along median line, tip elongated, pointed (in lateral view with 2 teeth towards SS, the lower with numerous hairs); phallus trifid, extremely long, coiled with supporting structure; ejaculatory apodeme fan shaped; sperm pump with two lateral projections (planes of the two latter parts are turned by 90 degrees). The frons of the female narrows in front of the ocellar triangle, and the pulvilli are as long as the last tarsal segment.
