Stylocellidae

The Stylocellidae are a family of harvestmen with about 40 described species, all of which occur in Southern or Southeastern Asia. Members of this family are from one to seven millimeters long. While Stylocellus species have eyes, these are absent in the other two genera.

Name

The name of the type genus is combined from Ancient Greek stylos "pillar" and Latin ocellus "eye", referring to the elongated shape of the animal, compared to Sironidae, and the presence of eyes.
