( Figs. 1 , 2 , 3 ) Description. Head slightly narrower than pronotum, crown with anterior margin subparallel to posterior margin, coronal suture distinct ( Figs. 1a, c, e, g ). Face with frontoclypeus and anteclypeus narrow ( Figs. 1d, h ). Eyes grey, somewhat black ( Fig. 1 ). Face pale yellow ( Figs. 1d, h ). Vertex and streak along coronal suture orange and formed two pairs of patches in different sizes with light color ( Figs. 1a, c, e, g ). Patches on hind angles of pronotum and apex of scutellum, black; orange umbrella framework pattern across pronotum, scutum and scutellum yellow, somewhat orange, triangles yellow ( Figs. 1a, c, e, g ). Fore wings pale, semitransparent ( Figs. 1a, b, e, f ). Ground color of abdominal tergites yellow to orange, with transverse stripes on each tergite, black ( Figs. 1a, b, e, f ). Abdominal apodemes reaching middle of fifth sternite or nearly reaching sixth sternite ( Fig. 3b ). Anal tube appendage arcuate or with obvious right-angle bend medially, extending far beyond pygofer hind margin ( Figs. 2a, b ; 3g , h ). Pygofer side with three to five macrosetae at lower basal angle and row of nine to ten rigid setae at hind margin ( Figs. 2a, b ). Subgenital plate with exceedingly long and well pigmented at distal region of apex; with three macrosetae at transitional part; without minute peg-like microsetae at the angle of caudal part; narrowed area short ( Figs. 2a, b ; 3a ). Paramere apical part elongated with two dentate processes medially distinct or not, well bent ( Figs. 3e, f ). Aedeagal shaft broad, straight, as long as or shorter than preatrium ( Figs. 3i , j ). Small bifurcated process at apex of aedeagus in caudal view ( Fig. 3k ). FIGURE 1.

Measurement. Length of male 4.1-4.4mm (including wing). Material examined. Holotype : ♂ , CHINA , Guangxi Prov. , Youjiang , Longhe , at lamp, 27 June 2018 , coll. Shuanghu Lin ; Paratypes : 12♂♂ , same data as holotype ; ♂ , CHINA , Guangxi Prov. , Youjiang , Longhe , at lamp, 28 June 2018 , coll. Shuanghu Lin. Deposition. Entomological Museum, Northwest A&F University, Yangling, China . Remarks. This new species is extremely similar to R . curtihamata but can be distinguished by the shorter aedeagal shaft, the anal tube appendage extending far beyond pygofer hind margin, eyes grey, somewhat black, face with frontoclypeus and anteclypeus narrow, and centre of frontoclypeus without dark apically. Etymology. This new species is named after its type locality “Longhe”.
