Zanchius virescens Usinger 1946, new species

72. Zanchius virescens, new species (fig. 20, d).

Elongate, sparsely pubescent, pale with large green areas on clavus, corium, and in the cells of membrane. Right genital clasper in male small, lobelike, without curvature, spines or processes.

Head two thirds as long as broad across eyes, 16: 24, the eyes large, half as wide as interocular space, 6: 12. Entire vertex broadly depressed at center but this may be due to shriveling of specimen. Clypeus strongly convex, transversely impressed at base. Rostrum extending well beyond apices of hind coxae, proportion of segments 11: 14: 18: 13. Antennae about as long as body including membrane, proportion of segments 14: 60: 35: 28.

Pronotum longer on median line than head, 18: 16, less· than twice as wide across humeri as long, 33: 18, the sides strongly sinuate behind miclclle,rounded anteriorly, the front margin concave at miclclleand minutely margined. Hine\ margin broadly, shallowly concave. Disk smooth, moderately elevated anteriorly where it is feebly longitudinally impressed, hind lobe subdepressecl.

Hemelytra very long, the apices of coria exceeding apex of abdomen, corial margins slightly arcuate, over twice as long as width of pronotum, 76:33; 3.5 times as long as cuneus. Corial margins widened at apex. Clavus, corium, cuneus, and area within membranal cells subhyaline.

Male right genital clasper short, narrow, simple, uncurvecl, without spines of processes. Left clasper wide, arcuate, not forming a complete semicircle.

Color entirely pale, whitish ochraceous with brown apex of rostrum and processes of aedeagus. Hemelytra subhyaline spotted with numerous small white punctures apically and sublaterally on corium and near base of membranal cells. Clavus tinged with green at middle of basal half. Corium broadly covered with small green punctures on basal half except at extreme base, with a broad green area beyond middle, another at apex, and two large green areas in membranal cell. Cuneus clear, hyaline, with testaceous margin and green apex. Membrane outside of cells clear hyaline.

Size: male, length 3.5 mm., width (hemelytra) 1 mm.

Holotype male, Upi Trail, May 5, Usinger.

Longer and more slender and differently colored than in other species with distinctive male genitalia.
