Diagnosis
Head from above wider than long, the frons, of which the posterior margin is ill-defined, lying on a different plane from the rest of the head. The antennae lie in pits below the overhanging lateral margins of the frons and the ocelli are situated on the vertex well away from the frons. The eyes are small but prominent, the lorae small and the clypeus more or less diamond-shaped. The labium is short, not reaching beyond the bases of the fore legs and the crown of the head is only visible from above laterally against the eyes. The pronotum is wide at the sides, separating the head from the bases of the tegmina and the anterior and posterior borders are not parallel to each other. The tegmen has a small appendix and only four apical cells; and the hind tibia is armed with numerous spines that arise direct from the tibia itself. The male genitalia consist of long, narrow subgenital plates and parameres and a flask-shaped aedeagus (Evans 1934).
Stenoscopus is unique in the width of the face and the close-set ocelli which give the eyes a "stalked" appearance (Hamilton 1980).
