PARATYPES : CHINA: YUNAN: 9 ♁♁, same data as holotype; 9 ♁♁, same data as holotype except Meng Zhang leg.; 5♁♁, same data as holotype except 800 m, 28.v.2009, Wei Cui leg.; 1 ♁, Jinghong, Bubeng village, 4.ix.2010, light trap, Meng Zhang leg.; 1 ♁, same data as former except Juan Han leg.; 16 ♁♁, same data as former except, 20.v.2012, Yanghui Cao leg.

Description. Ground color ( Figs 12 A–D) orange, eyes black, with four black patches along dorsal midline of body: vertex with big roundish patch at transition from crown to face and smaller one on hind margin, pronotum with oval patch in middle, scutellum with rhombic patch at tip. Scutellum pale basally. Forewing light tawny apically, veins orange.

Abdominal apodemes 2S in male ( Fig. 1C ) extended to middle of sternite VI.

Male terminalia. Anal tube ( Fig. 1D ) with narrow, well sclerotized dorsal ring at midlength. Pygofer side ( Fig. 1D ) with membranous area near dorsal margin, with numerous tiny denticulations, ventral margin membranous, hind margin slightly produced, with several microsetae on caudal angle; dorsal appendage ( Figs 1D, E ) short, broad basally, apex pointed and curved ventrad; ventral appendage ( Figs 1D, F ) short and slim. Subgenital plate ( Fig. 1H ) with about 6 macrosetae. Connective ( Fig. 1J ) with manubrium lamellate, very thin, central lobe angulate apically. Aedeagal shaft ( Figs 1K, L ) compressed, broad in lateral view, curved dorsad, with pair of processes apically, processes deeply branched at base, dorsal branch shorter than ventral branch, processes coral-shaped in caudal view; dorsal apodeme large, T-shaped in caudal view; gonopore central on ventral margin.

Measurements. Male body length 3.30–3.50 mm.

Etymology. The specific epithet is an adjective derived from the Latin noun “ corallium ” (= coral) and the suffix “- formis ” (= having the form of), referring to the coral- shaped aedeagal processes in caudal view.

Distribution. So far only known from Yunnan province in the south of China.
