In this species, the antenna reaches back only to the level of the posterior thoracic margin. Segments 1 and 2 are separate but segments 8 and 9 on the other hand are fused. Rows of minute spinules are present on various segments of the antenna. Those spinules on segments 3 to 10 inclusive run transversely, but in the more distal segments fro 12 to 23 inclusive they run longitudinally; the two terminal segments are devoid of spines.
