(fig. 4) almost straight, compressed at antennal insertion with broad, low ventral lamina which is evanescent toward tip, sides strongly, evenly converging from antennal insertion to tip, dorsal margin of scrobe distinctly oblique before evenly descending below eye. Female rostrum 0.74– 0.77 mm long; 1.61–1.68 as long as prothorax; in profile nearly straight, sides abruptly converging beyond antennal insertion, in apical 1/3 slightly diverging to tip, dorsal margin of scrobe weakly oblique anteriorly, produced into weak, blunt process before continuing below eye. Head in profile with dorsal margin broadly, slightly declivitous above basal margin of eye. Pronotum 0.40–0.47 mm long, at base 1.08–1.16 as wide as long; punctures shallow, interspaces flat, alutaceous. Elytra at middle with interval 2 twice as wide as adjacent stria, dull, with 1 row of minute punctures bearing scales similar to pronotum; striae deep, coarse, with scales slightly shorter than adjacent interval; on apex striae not more deeply impressed, joining 1 þ 2 þ 9 (2 prolonged laterally before joining 1 þ 9), 3 þ 4, 5 þ 6, 7 þ 8. Flight wings present. Male legs lack special characters.
