Agramma bishopae sp. nov.

( Fig. 2 )

Diagnosis. This species differs from all species of Oriental region by the complete biseriate costal area in combination with the stouter antennae with setae, the darker, longer, and less swollen pronotum, and the more elongate head.

Description. Male: Body length 2.20; width 0.82. COLORATION (fig. 2):, Yellowish, calli, sides of pronotum, and body beneath dark brown, head black, except margins of bucculae. SURFACE AND VESTITURE: Body shiny, fourth antennal segment pilose. STRUCTURE: Head: Armed with two tiny frontal spines, bucculae wide, three areolae wide, closed in front; antennae long and slender, two first segments slightly stouter, antennal segment measurements: I, 0.18; II, 0.15; III, 0.52; IV, 0.23; rostral sulcus wide and wider on metasternum, largely open behind; rostrum short, slightly extending beyond prosternum.

Thorax: pronotum a little gibbose, unicarinate; median carina distinct and slightly raised on posterior process, almost indistinct on top of pronotum; collar small, two to three areolae wide, not raised; paranota absent.Hemelytra long, a little wider than pronotum, without distinct boundary veins delimiting areas, except costal area; costal area straight, biseriate, areolae round and large; subcostal area triseriate, wider than costal area, areolae smaller than on costal area, not distinctly delimited from discoidal area, and both sloping downwards; discoidal and sutural areas almost indistinctly differentiated, discoidal area four areolae wide at widest part, sutural area four to five areolae at widest part. Hind tarsi short and enlarged.

Female: Body length 2.32, body width 0.92. COLORATION: As in males. SURFACE: As in males. STRUCTURE: As in males with exception of subcostal area, which is quadriseriate.

Etymology. This species is named in honour of the B. P. Bishop Museum from which numerous specimens were borrowed for this study.

Material examined. Holotype: 1M, BanMeThuot, 500 m, 16–18.V.1960, S. Quate coll. ( BPBM); Paratypes: 1F, Mt. Lang Bian, 1500–2000 m, 19.V–8.VI.1961, N.R. Spencer coll. ( BPBM); 1 specimen (sex not seen on carded specimen), Thanh Loc, N° 273, 12 /X/1988, Leg. Vasarhelyi ( HMNH).

Discussion. The new species A. bishopae differs from all other species of Agramma from the Oriental Region by the complete biseriate costal area. Agramma biseriata differs from this new species by the more setose and stouter antennae, the darker, longer and less swollen pronotum, and the head more elongate. This new species is also similar to A. sedale , but differs by the darker pronotum and the form of hemelytra. The hind tarsi are short, enlarged, and hairy. The species superficially resembles the genus Litadea China by the form of the hemelytra with indistinct areas (not delimited by boundary veins), and possessing large hind tarsi. However, the hind tarsi are less enlarged than Litadea , the hemelytra much narrower, and the antennae more slender and not pilose.
