  Type species:

   Aristyllis aristyllis Kirkaldy, 1906 by original designation.

Introduction

A small genus of three species all recorded only from the type specimens collected in the wet tropics of North Queensland. Recognition of the genus is dependent on examining Kirkaldy's (1906) type material. Kirkaldy (1906) differentiates the species using colour.

Diagnosis

Vertex slightly declivous, more or less confused with the frons; the lateral margins fork, about their middle, (as seen dorsally), the inner keels meeting at an angle on the anterior margin (as seen dorsally), carinate medianly, posterior margin emarginate angulately. Frons obsolescently carinate medianly, the apical half excavated horseshoe-shaped. Clypeus more strongly carinate medianly, carinate (as also frons) laterally. A white opaque band across face. Eyes large, each about as wide as vertex. Ocelli distinct. Pronotum short, wider than head, tricarinate. Scutellum tricarinate. Tegminal venation not granulate. Legs spineless, or with one spine. (Kirkaldy 1906)

In his key to genera of Achilidae, Kirkaldy (1906) indicates that the frons is strongly impressed transversely, not or very obsolescently carinate and with a transverse white band.
