Plectromerini

Classification

Introduction

The tribe Plectromerini Nearns & Branham, 2008 currently contains 28 species in 1 genus. Photographs of 22 exemplar specimens are available for this tribe.

Diagnostic Features of Adults

Body size variable, from small (less than 10 mm) to moderate-sized (between 10-40 mm); generally elongate. Eyes generally reniform, complete (not completely divided into upper and lower lobes). Antennae generally filiform, unarmed; antennae 11-segmented, long, extending beyond tip of abdomen. Pronotum generally elongate (distinctly longer than wide); or approximately subquadrate (about as long as wide); lateral margins of pronotum unarmed, without distinct spines or tubercles. Mesocoxal cavities closed to mesepimeron. Elytral apices variable, with distinct spines or not. Metafemora armed with distinct tooth.
Plectromerini is superficially similar to Curiini but is easily distinguished by the third antennomere about as long or distinctly shorter than scape (third antennomere distinctly longer than scape in Curiini); and prosternal process between procoxae gradually or abruptly declivous (prosternal process between procoxae nearly flat, not gradually declivous in Curiini).
