Genus Ulonemia Drake and Poor, 1937

Perissonemia (Ulonemia) Drake and Poor, 1937: 3 .

Ulonemia: Drake, 1942: 359 ; Drake and Ruhoff, 1960a: 29; 1960b: 87; 1965a: 419; Jing, 1981: 289; Péricart, 1992: 83; Péricart and Golub, 1996: 77.

Type species by original designation: Perissonemia (Ulonemia) dignata Drake and Poor, 1937 .

Diagnostic characters. Body oblong-ovate, or elongate, nearly parallel-sided. Head short, weakly extended anteriorly to eyes, armed with five spines, frontal and median ones short, stout. Bucculae narrow, areolate. Antennae long, slender, pubescent; segment I short, segment II shortest, segment III longest.

Pronotum moderately convex, tricarinate, calli deeply impressed, covered with dense pruinescence. Hood moderately elevated. Median carina long, contiguous to hood, raised along pronotum; lateral carinae reaching calli. Paranota narrow, erected or reflexed against pronotum, uni- to triseriate. Pronotal posterior process areolate. Scent gland ostiolae elongate.

Hemelytra longer than abdomen. Costal area narrow, uni- to biseriate, areolae usually quadrate. Subcostal area biseriate, areolae usually in regular arrangement. Discoidal area extending beyond middle of hemelytra, six to nine areolae broad at widest part. Hypocostal laminae uniseriate.

Discussion. Ulonemia can be recognized from other genera of Oriental Tinginae , especially the relative genera Cromerus Distant, 1902 , Eritingis Drake and Ruhoff, 1962 , Leptoypha Stål, 1873 , Perissonemia Drake and Poor, 1937 , by the following combination of characters: hood moderately elevated, paranota erected or reflexed against pronotum, uni- to triseriate. In contrast, the hood is absent in Cromerus , Eritingis , Leptoypha and Perissonemia . Moreover, the paranota are ridge-like in these genera, with the exception of the uniseriate paranota in Eritingis .

Distribution. China, India, Borneo, Vietnam, Malaysia, Philippine, New Guinea, Australia ( Drake and Ruhoff 1965a; Péricart and Golub 1996).
