Description
Size (female): length 1.0 mm.

The proportional lengths of the cephalothorax and abdomen are as 83 to 21, so that the abdomen is contained 3.95 times in the length of the anterior region. There is no trace of the line of fusion between the cephalon and the 1st thoracic segment.
The 1st antenna reaches beyond the tip of the furcal ramus by the last three segments. The 1st and 2nd segments are completely fused and segments 8 and 9 are also partially fused but the line of demarcation between them can be easily detected.
