Vertex 2.58 times wider than long in midline (1.29 mm and 0.50 mm respectively); anterior margin slightly arcuate, lateral margins straight, posterior margin weak and concave, disc of vertex depressed, transverse carina present between frons and vertex. Frons quadrangular, convex in lateral view, with a median carina reaching dorsal margin but not frontoclypeal suture. Antennae 0.94 mm long; pedicel ring-shaped and scape globose, longer than broad. Clypeus wider at base than frons apical part; clypeal suture concave. Rostrum long, reaching the base of the metacoxae.</p><p><i>Thorax</i>. Pronotum 1.55 times wider than vertex in midline; anterior margin angulate, reaching first third of the compound eye’s length; without median carina, but with two lateral carinae. Mesonotum narrower across midline than pronotum and head vertex; with a weak median carina in posterior part; lateral margins incurved, metanotum distinctly wider anteriorly than posteriorly, diamond-shaped.</p><p><i>Legs</i>. Prothoracic tibia quadrangular, longer than prothoracic femur and mesothoracic tibiae. Mesothoracic tarsi distinctly shorter than prothoracic and metathoracic tarsi. Metathoracic legs 1.82 mm long, metathoracic femur slightly flattened, with strong lateral margins; metatibia distinctly longer than prothoracic and mesothoracic tibiae, depressed ventrally, quadrangular, with strong lateral margins, with three lateral spines, first one smaller than others.</p><p><i>Forewings</i>. Tegmina 5.89 mm long, maximum width across tegmina 2.80 mm, costal and apical margin strongly curved, anal margin nearly straight. Costal area present, with numerous simple and straight veinlets, basad to clavus apex. ScP+R short, forking into ScP+RA and RP at 1.29 mm from forewing base, well distad M fork. ScP+RA stem 0.87 mm long. RP long, almost half of wing total length, with numerous branches, <i>rp -m</i> located distad <i>m -cua</i>. M stem long, about a third of wing total length, forking into M 1+2 and M 3+4 at 1.83 from wing base, distad PCu+A 1 fusion. CuA simple and straight, subparallel to CuP, <i>cua -cup</i> slightly incurved, meeting CuA at point of separation between CuA and M. CuP straight and reaching wing margin at 4.59 mm from wing base. PCu sinuous, distally fusing with A 1 at 2.06 mm from wing base, clavus closed and 3 / 4 of total length of tegmina. All apical crossveins gathered in a row, subparallel to apical margin of wing.</p><p><i>Hind wings</i>. Wings membranous, 2.80 mm long. ScP+R stem long reaching almost apex of costal margin, at 1.82 mm from wing base. RP with two branches emerging from a short stalk, <i>rp-m</i> distad <i>m-cua</i> and neither basad nor distad <i>m-cua</i>. M stem long, forking into two main branches at 2.21 mm from the hind wing base. CuA with five terminals, first level of forking distad forking of both ScP+R and M. CuP straight reaching anal margin at 1.79 mm from wing base. Claval veins obscured.</p><p><i>Abdomen</i>. Female terminalia poorly preserved. No internal genital structures preserved (as revealed with CT scan construction).</p> |
