Introduction

Fourteen genera of Arhytodini are now known, with five of these being Neotropical, six are from Madagascar, one is from the Congo, one from Sabah, and one is found in Australia and Papua-New Guinea (Chandler 2001: 498).

Diagnosis

Body often with squamous setae in sulci, foveae, or at articulations of major body parts. Head with prominent frontal rostrum; often with setose sulci extending dorsally from areas of lateral postantennal pits to vertexal foveae; clypeus broadly rounded at apex, margins then relatively straight to eyes; with short to long gular-mandibular carinae, only Caccoplectus (Neotropical) instead with ocular-mandibular carinae; maxillary palpi small; apicolateral genal projections often broad. Pronotum lacking paranotal carinae. Abdomen with visible tergites 1-4 (IV-VII) subequal in length; 1 (IV) with deep basal sulcus; 4 (VII) with paratergites angularly projecting; visible paratergites 1-3 (IV-VI) often with basal foveae. Visible sternite 2 (IV) with deep basal sulcus. Legs with single tarsal claws; femora often with spines.
