Stephanitis (Norba) vietnamensis sp nov.

( Fig. 4 )

Diagnosis. The triseriate costal area and the biseriate sutural area distinguish this species from the other of the Oriental Region.

Description. Male. Body length 3.56; width 2.43. COLORATION: whitish to clear brown; body beneath darker; darker spots on front of the hood, top of median carina, tumid part on costal area, and a darker transversal band at apex of hemelytra. SURFACE AND VESTITURE: Body shiny and hyaline, margins and veins of pronotal structure and hemelytra slightly serrate and pilose. STRUCTURE: Head: Small, armed with five long and slender spines, bucculae short, biseriate, closed in front; antennae long and slender, antennal segment measurements: I, 0.42; II, 0.12; III, 1.34; IV, 0.71; rostral sulcus wide, slightly widened posteriorly, open behind; laminae wide, uniseriate, and serrate; rostrum reaching apex of metasternum. Thorax: Pronotum a little gibbose, punctate on top, areolate on hind process, unicarinate, median carina high, triseriate, areolae large, outer row of smaller areolae, margin serrate; collar narrow, biseriate, areolae tiny; hood greatly enlarged, longer than wide, eight areolae long from apex to connexion to median carina, covering head and extending in front of head at two first antennal joints length, as high as median carina; paranota reflexed, wide, four areolae wide, outer row of smaller areolae. Hemelytra sharply widened at base, divergent posteriorly; costal area wide, sinuate, six areolae wide at widest part, areolae polygonal and large, a tumid spot in widest part; subcostal area wide, almost vertical on basal part, then sloping downwards, biseriate anteriorly and posteriorly, uniseriate near middle where costal area the widest; discoidal area less than half the length of hemelytra, three areolae wide at widest part; RM vein separating discoidal and subcostal area strongly raised; sutural area biseriate.

Female: Unknown.

Etymology. This species is named after the country of the Socialist Republic of Vietnam.

Material examined. Holotype: 1M, 25 km SW of Pleiku, 400 m, 12.V.1960, L.W. Quate coll. (museum?); Paratypes: 1M, same data as holotype; 1M, Ban Me Thuot, 500 m, 16–18.V.1960, L.W. Quate coll. ( BPBM). Discussion: This species is close to S. chinensis Drake , but its sutural area is biseriate, not triseriate. It is also close to S. buthanensis Péricart but its costal area is not triseriate.
