Description
Size: Male 3.905-4.60 mm; Female 5.54-6.0 mm.

Female : The proportional lengths of the cephalothorax and abdomen are as 32 to 17, so that the abdomen is contained 1.88 times in length of the anterior region of the body.
The forehead is rounded and is provided with a pair of delicate rostral filaments that arise from a swollen base. On each side of the head there is a stout triangular spine. The posterior thoracic margin is bluntly rounded.
The abdomen consist of four free segments, segments 1 to 2 being fused in the genital segment. The two middle segments, segments 3 and 4, are much narrow than either the genital or anal segment. The furcal ramus is only one-and-a-quarter times as long as the anal segment. The 2nd furcal seta is long and stout and is equal in length to the whole abdomen, including the furcal ramus.
The 1st antenna reaches back nearly to the middle of the furcal ramus.

Male: The proportional lengths of the cephalothorax and abdomen are as 119 to 88, so that the abdomen is contained 1.352 times in the length of the anterior region of the body. The head is produced on either side in a well developed spine. The posterior thoracic margin is rounded. The rostrum consists of a pair of tapering filaments.
The furcal rami are five times as long as broad and the 2nd furcal seta is as long as the whole abdomen and is three times the length of the other furcal setae. The outer seta is short and spine-like and arises from the outer margin one-seventh of the length of the whole ramus from the proximal end. The inner margin of the fucal rami are fringed with hairs.
The 1st antenna reaches to the posterior margin of the anal segment; that on the left side is modified to form the usual grasping organ.
