Labicerus elegans Erichson in Schomburgk, 1848 by monotypy.</p><p>Diagnosis. 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>Remarks.  Labicerus (Figs. 1, 2) appears to be superficially most similar to  Platonax (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.  Platonax also appears to have distinctly broader antennae than  Labicerus . Among genera with an antennal appendage  Apache,  Otiocerus, and  Shellenius (Figs. 5B, E, H) all have a much more strongly projected head, and  Kubilaya has the leading margin of the wing scalloped and a pair of large tubercles on the thorax (Fennah 1945, 1952 as  Iquitosa Fennah).</p><p>Etymology. The genusnameis derived from the Greek terms “ laví ” (λαβή, handle), combined with “ kéras” (κέρας, horn, antenna), and is masculine in gender (Dmitriev, 2002).</p></div>	https://treatment.plazi.org/id/03A6878CFFCBFF9CE620A72666E5326D	Public Domain	No known copyright restrictions apply.

Apale species bearing whitish forewings with dark maculations. Head in lateral view smoothly semicircular from vertex to frontoclypeal suture, projected in front of eye for distance less than greatest width of eye. Antennae elongated (exceeding anterior head margin) with single elongated serpentine projection from near the base of the pedicel, pedicle flattened in cross-section.</p><p>Amended description.</p><p>Color. Body irregularly patterned from yellow-brown to brown (probably paler in life; Fig. 1). Antennae yellow-tan, fore and middle leg brown, hind leg paler. Forewings (Fig. 1E) whitish with concolorous veins bearing dark markings on cells and veins as follow: vein CuA2 and proximal part of CuA1 (to m-cu crossvein), first fork of MP (MP1+2 from MP3+4) and first r-m crossvein; dark spot near distal apex of basal cell, 2 dark spots in clavus, between vases of MP and CuA, at apices of cells C5, C4 and C3, near forks of MP 1 and MP 2, and two subsequent forks of MP 1 (MP 1.1 from MP 1.2, MP 1.1.1 from MP 1.1.2) and in most apical cells.</p><p>Structure. Body length (including wings) about 10.5 mm. Head much narrower than pronotum. Vertex narrowly triangular with lateral margins foliately elevated, bearing a row of pustules (continuing on to frons), narrowing anteriorly, approximated apically, disc strongly concave, posterior margin concave. Frons (Fig. 2A) strongly compressed, in frontal view lateral margins strongly approximate, in lateral view (Fig. 2B) smoothly semicircular from posterior margin of vertex to frontoclypeal suture (projected in front of the eye for less than the width of the eye). Clypeus angled 90 degrees from frons in lateral view, in frontal view narrowly triangular. Antennae elongated, exceeding dorsal margin of head; scape short, about as long as wide, pedicle elongate and flattened in cross-section, bearing an elongate curved appendage (Fig. 2C) from the ventral surface. Eye semicircular, lateral ocellus apparently obsolete.</p><p>Pronotum in dorsal view short along midline, posterior margin deeply angulate; in lateral view, posteriorly inclined, paradiscal region broad, apically truncate at level of ventral margin of eye. Mesonotum relatively large, appearing tricarinate, scutum convex in lateral view, in dorsal view posterior margin of mesoscutellum rounded; lateral margin of mesothorax carinate. Posterior tibiae laterally unarmed, distally with 4(1+3) denticles, these with separated lateral spine largest, remaining smaller and arranged in an oblique row; metabasitarsus with 4 small uniform denticles in crescent-shaped row; second tarsomere bearing 5 small denticles, lateralmost slightly larger than median 3, in crescent-shaped row. Setae between denticles of both tarsomeres. Metabasitarsus about twice length of next tarsomere, approximately the length of second and thirds tarsomeres cumulatively. Pretarsal claws prominent, slender; arolia distinct (not reduced).</p><p>Forewings (Fig. 3) elongated and spatulate, narrowest basally, widest in distal 2/3 length, trailing margin broadly convex. Clavus open, composite vein Pcu+A1 projecting anteriorly to encompass CuP and branches of CuA before reaching wing margin past midlength; marginal cells at wing apex mostly longer than broad. RP branching from ScP+R near apex of basal cell; ScP reaching wing margin near forewing midlength. Branching pattern RA apparently 4- branched, RP 2-branched, MP 7-branched, CuA 2-branched (anastomosed to form closed procubital cell (Emeljanov 1996).</p><p>Male terminalia unknown.</p><p>Remarks. In the female specimen of  Labicerus elegans, the forewings are curled in a fashion that makes interpretation difficult. It appears that the RP and MP veins are joined proximally and fork near the wing midlength, but such an arrangement is not found in other  Otiocerini to our knowledge, and the base of the MP may be obscured by the uneven plane of the wing. Since the branching of RP+MP would be quite unusual in  Otiocerini, we would like to confirm this observation with additional material when it becomes available.</p><p>Material examined</p><p>Type material</p><p>Labicerus elegans (Syntype, 1 specimen, ZMHB, female) “4990 //  Labicerus / elegans / er / Brit.
