Nota: The length of urosome is contained 4 times in that of the cephalothorax. Rostrum strong and slender, one-pointed and directed downwards. The 4th and 5th thoracic somites completely fused, the line of fusion is only visible in dorsal aspect on the back. The corners of the last thoracic segment carrying a number of hairs. The 1st and 2nd urosomal somites are fused to form the genital complex (double-somite); there is a curious, more or less bilobated sac-shaped protuberance on the right side.
