Classification

Introduction

The tribe Phytoeciini Mulsant, 1839 currently contains 337 species in 32 genera. Photographs of 2 exemplar specimens are currently available for this tribe.

Diagnostic Features of Adults

Body small to moderate-sized, approximately 10-40 mm; generally elongate; body without metallic reflection. Eyes variable, from reniform and complete (not completely divided into upper and lower lobes) to divided (completely divided into four separate lobes). Antennae filiform, unarmed; antennae long, generally extending beyond elytral apices by several segments. Head without distinct lateral or anterior projections. Pronotum approximately subquadrate (about as long as wide); lateral margins of pronotum without distinct spines or blunt tubercles. Mesocoxal cavity open to mesepimeron. Wings generally complete. Legs with tarsal claws appendiculate or bifid; claws narrowly to moderately separated (divergent) to broadly divergent (divaricate).

Diagnostic Features of Larvae

Larva. Head thick, widest across posterior limit of frons, with sides strongly converging posteriorly rather as in Agapanthia. One pair of ocelli present; one, two, or three pairs of vestigial ocelli sometimes present. Clypeus glabrous. Hypostoma with a transverse row of setae. Gula indiscernible. Antenna two-segmented. Mentum distinct from submentum. Prothorax with posterior part of pronotum coarsely asperate; sublateral impressions linear, straight, long and brownish. Abdomen with each dorsal ampulla with a single transverse furrow. Pleural tubercle with two stout setae. Adapted from Duffy (1953).
