- <p><b>Genus <i>Labicerus</i> Erichson in Schomburgk, 1848</b></p><p><b>Type species.</b> <i>Labicerus elegans</i> Erichson in Schomburgk, 1848 by monotypy.</p><p><b>Diagnosis.</b> Head in lateral view semicircularly rounded, projected in front of eye for less than width of eye (longest axis). Antennae elongate, longer than frons, and bearing an elongated projection; pedicle flattened. Wings with MP branching from ScP+R in proximal third of wing; ScP forked from RA near wing midlength.</p><p><b>Remarks</b>. <i>Labicerus</i> (Figs. 1, 2) appears to be superficially most similar to <i>Platonax</i> (Fig. 3), including the general shape of the head (Figs. 5D, F) and the general coloration of the body and wings, but that genus lacks the appendage on the antennae. <i>Platonax</i> also appears to have distinctly broader antennae than <i>Labicerus.</i> Among genera with an antennal appendage <i>Apache</i>, <i>Otiocerus</i>, and <i>Shellenius</i> (Figs. 5B, E, H) all have a much more strongly projected head, and <i>Kubilaya</i> has the leading margin of the wing scalloped and a pair of large tubercles on the thorax (Fennah 1945, 1952 as <i>Iquitosa</i> Fennah).</p><p><b>Etymology</b>. The genusnameis derived from the Greek terms “ <i>laví</i> ” (λαβή, handle), combined with “ <i>kéras”</i> (κέρας, horn, antenna), and is masculine in gender (Dmitriev, 2002).</p>
