description: Buca truncoptera sp. nov. (Figs. 5, 8B)   
 Diagnosis. Color green yellowish with very dark dorsal vitta across coryphe, pronotum, and mesonotum; apical cells of wing with dark brown patches. Trailing margins of forewings truncately rounded with ScP+RA separated before the margin in ScP and 2 branches of RA, 9 branches of MP and 4 r-m crossveins.   
 Description. Color. General coloration light green yellowish. Metope with black spot medially below its upper margin. Third segment of rostrum orange apically. Coryphe, pro-, and mesonotum with wide dark median stripe, black with orange margins; stripe continuing on claval margins of forewings. First anal vein of forewings orange. Apical cells of forewing with dark brown patches. Hind wings with postcubitus and anal veins black. Abdominal tergites V–VII with red median stripe. Leg spines with black apices. Structure. Body length (with wings; ♀ holotype) 8.5 mm, body length (without wings), 5.4 mm. Metope sharply enlarged near level of antennae in frontal view, with distinct median carina running from fastigium to level of antennae, obsolete ventrad of antennae. Lateral margins of metope sharp, laterally projected, hiding scape in frontal view. Clypeus with carina absent. Coryphe broad (Fig. 5B), anterior margin of coryphe convex, posterior margin concave. Pronotum short with median carina, disc small, paranota narrow, acutely angulate, nearly reaching tegulae. Mesonotum very large, approximately 6 times as long as pronotum medially (ratio of mesonotum length excluding scutellum to pronotum length = 6.08), with weak carinae. Forewings long (6.9 mm), extending well past end of abdomen, and wide (3.8 mm), truncately rounded (Figs. 5A and 8B). Forewing venation: forewing with crossveins absent in costal area; basal cell large; ScP+RA (branch ScP+RA forked from RP in proximal third of wing) branched into ScP, RA1, and RA2 distally; RP 3-branched with rp1-rp2 crossvein; 4 r-m crossveins; MP 9-branched (MP1 with 5 branches and MP4 with 2), 1 m-cu crossvein, CuA only very distally forked for a minute C5, 3 cup-pcu crossveins near apex of clavus. Hind tibiae with 7 spines apically.   
 Female terminalia. Anal tube short, slightly narrowing apically, truncated.   
 Remarks. This species is described from a single female specimen with the right side of the head damaged.   
 Etymology. The specific epithet is derived from the Latin word “ truncus ” (maimed, cut off) combined with the Greek term “ pteron ” with the feminine termination “ -a ”; a reference to the relatively truncate forewings.
