Labicerus Erichson in Schomburgk, 1848 (Hemiptera: Derbidae: Otiocerinae)

The derbid genus Labicerus, and its single component species Labicerus elegans, was succinctly described by Erichson in Schomburgk (1848) from Guyana but subsequently remained obscure. Here we redescribe and illustrate the genus and species from a rediscovered syntype specimen. We present a preliminary key to the New World genera of Otiocerini and briefly contrast Labicerus with Platonax Metcalf, 1938, from Panama, which appears to be the superficially most similar taxon.

We also provide a checklist of species of New World Otiocerini along with a synoptic distribution for each species.
