General body color dark brown (Fig. 10), lighter on mesonotum from median carina to lateral carinae; head, pronotum and legs almost testaceous (Fig. 11); forewings clear, slightly tinted yellow in basal half, irregularly mottled with fuscous patches (Fig. 10).</p><p><i>Structure.</i> Body length with wings; male 4.6 mm, female 4.8 mm (Table 3). Head. In dorsal view (Fig. 11A), head roughly quadrangular, wider anterior to eyes, width at widest point about 2.2X length at midline. Vertex with apical transverse carinae arched, extending transversely to join at midline just in front of eyes (bisecting head apex, joined anteriorly by extension of median carina of frons); subapical transverse carina absent (or along posterior margin); median carinae obsolete, disc depressed (bearing defined pit on either side of midline); anterior and posterior margins concave; in lateral view (Fig. 11B), profile irregularly sinuate, vertex posterior margin raised, irregularly declinate anteriorly, projecting in front of eyes, lateral margins of head forming deep elongated depression, antennae situated directly anterior to eyes, lateral ocelli dorsal to antennae at anterodorsal margin of eye, transverse carina on gena below antenna between ventroanterior margin of eye to anterior margin of head. In frontal view (Fig. 11C), face broad, roughly triangular in shape, frons widest dorsally at auriculate expansion of head, constricting ventrad to frontoclypeal suture, median carina distinct to median ocellus; distinct lateral carinae, meeting medially below antennae, forming a U-shaped tablet from level of ventral margin of eyes to beneath the median ocellus. Frontoclypeal suture obscure and roughly transverse (a pair of lateral dark markings near lateral extensions of frontoclypeal sutures perhaps marking anterior tentorial pits). Eyes in lateral view roughly dumbbell shaped (long axis vertical). Antennae short, scape hidden, pedicel wider than tall, roughly C-shaped in lateral view, bearing irregularly placed sensory plaques, flagellum setaceous with bulbous base.</p><p>Thorax. Pronotum in dorsal view very short with anterior margin linear, posterior margin deeply concave, appearing tricarinate (Fig. 11A). Mesonotum in dorsal view approximately as wide as long at midpoint, tricarinate (Fig. 11A). Forewing spatulate, narrow basally, expanding to approximately 2X the width in distal 2/3 after clavus; RA 2-branched, RP 3-branches, MP 5-branched, CuA 2-branched (Fig. 12). Hind tibiae lacking lateral spines, apical spinulation of tibal apex and tarsomeres 5-6-6.</p><p>Terminalia. Pygofer in lateral view narrow dorsally, expanded ventrad (widest near midpoint), constricted ventrad except expanded on ventral margin; anterior margin concave, posterior margin irregularly sinuate (Fig. 13A); in ventral view, medioventral process subtriangular, approximately as wide as long at midpoint (Fig. 13B). Gonostyli in lateral view stout, angled dorsad, dorsal surface concave, apex rounded; subtriangular projection on ventral margin near midlength (Fig. 13A); in ventral view, gonostyli approximated, lateral margins subparallel, ventral projections arising medially, apices semitruncate (Fig. 13B). Aedeagus complex, shaft straight, tubular, apex bearing large, shield-like flange (AF, Figs. 14B, 15B), extending almost to aedeagal base on left lateral margin, in dorsal view (Figs. 14A, 15A), apex pointed, small process (AP) rising on outer lateral side near midpoint, angled dorsad. Endosoma helically twisted, split into two regions, posterior region curved dorsally over shaft to right lateral side, bearing one large, serrated process (E1); anterior region larger, bearing rounded process (E2) along dorsal margin on left lateral side and two additional lateral processes curving ventrad, surrounding aedeagal shaft, process arising on left lateral side (E3) curving dorsally initially over aedeagal shaft then ventrally and process on right lateral side (E4) immediately curving ventrally. Two rows of serrations along dorsal margin of anterior region (Figs. 14, 15).
