Description. Body elongate, light reddish brown; head black, densely covered with pale pruinescence, Fourth antennal segment dark brown, remaining three segments brown ( Fig. 6 View FIGURES 5 – 6 ), clothed with pale pubescence; paranota yellowish brown. Ventral surface of body brown ( Fig. 18 View FIGURES 15 – 18 ).

Head short, front and median spine stout, suberect, occipital pair slender, appressed, reaching base of median one ( Fig. 14 View FIGURES 11 – 14 ); bucculae narrow, tapering anteriorly, opening in front, biseriate, inferior margins almost straight; rostral sulcus narrow, nearly parallel, opening behind; rostrum extending to middle of metasternum ( Fig. 18 View FIGURES 15 – 18 ).

Pronotum rather strongly convex, distinctly punctate ( Figs. 10 View FIGURES 7 – 10 , 14 View FIGURES 11 – 14 ); hood greatly inflated, globular in dorsal view ( Fig. 10 View FIGURES 7 – 10 ), conspicuously sloping posteriorly, considerably higher in height than median carina, eight areolae long, six areolae broad on each side, anterior margin produced, round, posterior margin reaching near middle of pronotal disc ( Fig. 14 View FIGURES 11 – 14 ); median carina contiguous to hood, somewhat raised, uniseriate, areolae tiny, higher in height than lateral carinae; lateral carinae terminating at calli, extremely low, ridge-like, not areolate, converging anteriorly, parallel at posterior pronotal process; paranota reflexed upward, narrow, distinctly triseriate at calli, narrower posteriorly, biseriate opposite humeri, areolae relatively large, quadrate ( Fig. 14 View FIGURES 11 – 14 ). Calli and thorax ventral surface densly covered with white pruinescence.

Hemelytra distinctly wider than pronotum, margins sinuated ( Fig. 6 View FIGURES 5 – 6 ); costal area narrow, length regularly uniseriate, areolae mostly widthwise quadrate; subcostal area nearly as wide as costal area, regularly biseriate, areolae round; discoidal area extend more than half length of hemelytra, seven areolae broad at widest part; sutural area wider than discoidal area, eight areolae broad at widest part, areolae polygonal; hypocostal laminae uniseriate, areolae nearly quadrate.

Measurements. Females (N =3). Total body length: 3.68–3.72 (3.69); body width (across hemelytra): 1.10–1.22 (1.16); antennal segments I: 0.22–0.24 (0.23); II: 0.13–0.14 (0.13); III: 1.58–1.70 (1.64); IV: 0.60–0.62 (0.61); pronotum length: 1.64–1.72 (1.67); width: 0.98–1.04 (1.01); hemelytra length: 2.72–2.76 (2.73); discoidal area length: 1.52–1.56 (1.54).

Type material. Holotype: Yunnan Province: female, Jingdong County, Ailaoshan Natural Reserve, Xujiaba (N 24.52, E 100.95), 8.III.1982, (No. 82-005349) ( NKUM). Paratypes: Yunnan Province: 1 female, China, Xishuangbanna, Mengzhe Township (N 21.99, E 100.26), Alt. 1950 m, 25.VII.1958, Shuyong Wang leg. (Chinese Academy of Sciences); 1 female, China, Baoshan City, Longyang, Baihua Ling (N 25.29, E 98.81), Alt. 1600 m, 11.VIII.2006, Weibing Zhu leg. ( NKUM); 1 female, Yuanjiang County, Weili Town, Alt. 1800 m, 20.VII.2006, Jimeng Hua leg. (EG003) ( NKUM).

Etymology. The species name is derived from the Latin noun magnus (=large), in reference to its hood much larger than other species of Ulonemia .

Discussion. The hood of Ulonemia magna sp. nov. is much larger than that of other species of Ulonemia , and extends nearly to middle of pronotal disc ( Figs. 10 View FIGURES 7 – 10 , 14 View FIGURES 11 – 14 ). Ulonemia magna sp. nov. differs from the Chinese Ulonemia species by its paranota triseriate at calli, biseriate opposite humeri, whereas they are biseriate at calli and uniseriate at humeri in the other Chinese Ulonemia species ( Figs. 11–14 View FIGURES 11 – 14 ).
