The spider is large with a cephalothorax between 2.6 and 3.5 mm long and a abdomen between 2.2 and 4.4 mm. The female is larger than the male. The spider has a brown carapace that has two white streaks on the thorax a black eye field. It has the toothless chelicerae typical of the genus. It can be distinguished by its abdominal pattern, which has a yellow streak of an irregular shape. The male has a hidden embolus that is shorter than that on the related Langona pilosa.
