Classification

Introduction

The tribe Pogonocherini Mulsant, 1839 currently contains 492 species in 33 genera. Photographs of 3 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 generally reniform, complete (not completely divided into upper and lower lobes). Antennae filiform, unarmed; antennae long, generally extending beyond elytral apices by several segments. Head without distinct lateral or anterior projections. Pronotum shape variable, from approximately subquadrate (about as long as wide) to transverse (distinctly wider than long); lateral margins of pronotum variable, with or without distinct spines or blunt tubercles. Mesocoxal cavity open to mesepimeron. Wings generally complete. Legs with tarsal claws smooth; claws broadly divergent (divaricate).

Diagnostic Features of Larvae

Larva. Form slender, subcylindrical. Head depressed, with sides slightly constricted behind middle. Mandible short, reticulate on outer face. Antenna] foramen closed behind. Setiferous pores of hypostoma absent. Antenna two-segmented and bearing a hyaline process. Maxillary palp two- or three-segmented. Gular region without distinct sutures or ventral cleavage line. Prothorax with posterior region of pronotum shining and glabrous. Abdomen with ampullae feebly tuberculate and with a broad, longitudinal, median furrow. Epipleurum protuberant on last three segments only. Pleural tubercles without sclerotized pits and with a single seta. Ninth tergum with a sclerotized process or plate. Spiracles with about six marginal chambers. Adapted from Duffy (1953).
