Redescription. Body elongate, pale brown; head black, densely covered with pale pruinescence, antennal segments brown, segment IV dark brown ( Fig. 1 View FIGURES 1 – 3 ), clothed with pale pubescence; paranota yellowish brown. Ventral surface of body brown ( Fig. 15 View FIGURES 15 – 18 ).

Head short, front and median spine stout, suberect, occipital ones slender, appressed, reaching forwards to middle of eyes ( Figs. 7 View FIGURES 7 – 10 , 11 View FIGURES 11 – 14 ); bucculae narrow, tapering anteriorly, opening in front, mostly biseriate, inferior margins nearly straight ( Fig. 11 View FIGURES 11 – 14 ); rostral sulcus narrow, nearly parallel, opening behind; rostrum extending to middle of metasternum ( Fig. 15 View FIGURES 15 – 18 ).

Pronotum rather strongly convex, distinctly punctate ( Figs. 7 View FIGURES 7 – 10 , 11 View FIGURES 11 – 14 ); hood inflated, globular in dorsal view ( Fig. 7 View FIGURES 7 – 10 ), height shorter than median carina, six areolae long, five areolae broad on each side, anterior margin produced, arched, posteriorly produced, reaching pronotal disc ( Fig. 11 View FIGURES 11 – 14 ); median carina contiguous to hood, somewhat raised, height higher than lateral carinae, uniseriate, with miniscule areolae; lateral carinae ridge-like, not areolate, slightly converging anteriorly, curved and converging posteriorly towards the pronotal posterior process, there, distance between lateral and median carina two areolae wide; paranota reflexed dorsally, narrow, distinctly biseriate at calli, narrower posteriorly, uniseriate opposite humeri ( Fig. 11 View FIGURES 11 – 14 ). Calli and thorax ventral surface densely covered with white pruinescence.

Hemelytra slightly wider than pronotum, margins nearly straight ( Figs. 1, 2 View FIGURES 1 – 3 ); costal area narrow, regularly uniseriate, areolae mostly widthwise ablong to subquadrate; subcostal area slightly wider than costal area, regularly biseriate, areolae round; discoidal area extending more than half the length of hemelytron, seven areolae broad at widest part; sutural area wider than discoidal area, ten areolae broad at widest part, areolae polygonal; areolae subquadrate on hypocostal laminae.

Female paratergite VIII distinctly produced posteriorly towards lateral margin of paratergite IX ( Fig. 19 View FIGURES 19 – 22 ).

Measurements. Males (N =3) and females (N =3) respectively. Total body length (male/female): 3.44–3.56 (3.51)/3.60–3.68 (3.65); body width (across hemelytra): 1.06–1.12 (1.09)/1.20–1.24 (1.23); antennal segments I: 0.20–0.22 (0.21)/0.22–0.24 (0.23); II: 0.12–0.14 (0.13)/0.12–0.14 (0.13); III: 1.56–1.58 (1.57)/1.52–1.54 (1.53); IV: 0.62–0.64 (0.63)/0.60–0.64 (0.62); pronotum length: 1.64–1.66 (1.65)/1.70–1.80 (1.75); width: 0.99–1.00 (1.00)/1.04–1.12 (1.07); hemelytra length: 2.48–2.64 (2.55)/2.60–2.68 (2.63); discoidal area length: 1.42–1.46 (1.44)/1.56–1.60 (1.58).

Material examined. Guangxi Province: 2 males, 4 females, Longsheng County, Cu Jiang (Licu Jiang) (N25.60, E 109.91). 23.VIII.1964, Liangchen Wang leg. ( NKUM); 1 male, China, Longsheng County, along the way form Tianpingshan Mountain to Baiya, 30.VIII.1964, Liangchen Wang leg. ( NKUM); 1 male, China, Huaping, Hongtan, Huaping Natural Reserve (N 25.59, E 109.97), 12.VI.1963, Chikun Yang leg. (The Department of Plant Protection, Beijing Agricultural University) ( NKUM).

Discussion. These specimens were previously identified as U. assamensis (Distant, 1903) by Jing (1981). After reviewing the lectotype deposited in the British Museum of Natural History (BMNH) in London, by authors Dr. E. Guilbert and Mr. K. Dang ( Fig. 2 View FIGURES 1 – 3 , dorsal photograph of lectotype habitus; Fig. 4 View FIGURE 4 , photographs of type label information), we concur with Jing’s the identification.
