According to a series of revisions of the genus Rugilus Leach from Palaearctic and Oriental regions (
The type material listed in the present study is deposited in the Insect Collection of Shanghai Normal University, Shanghai, P. R. China (SNUC).
The dissected body parts were mounted in Euparal on plastic slides. The habitus photos were taken using a Canon 7D camera. The photos of the sternites and aedeagi were taken using a Canon G9 camera mounted on an Olympus CX31 microscope.
Body length: measured from the anterior margin of the labrum to the apex of the abdomen.
Length of forebody: measured from anterior margin of the labrum to the posterior margin of the elytra.
Eye length: longitudinal length of eye in dorsal view.
Postocular length: measured from posterior margin of eye to posterior constriction of head.
Head width: width of head across (and including) eyes.
Head length: measured from the clypeal anterior margin to head base.
Pronotum width: maximal width of pronotum.
Pronotum length: measured in midline from front margin to posterior margin.
Width of elytra: combined width of elytra at posterior margin.
Length of elytra: measured from apex of scutellum to posterior margin.
Holotype: male: “China: Shaanxi Prov., Zhouzhi County, Houzhenzi, Qinling, Qinlingliang, N33.48.963, E107.44.483, alt. 2018 m, 7.V.2008, HUANG Hao & XU Wang leg.” (SNUC). Paratypes: 1 male, 1 female: “China: Shaanxi Prov., Mei County, Taibai Shan, Kaitianguan, N34.00.692, E107.51.415, alt. 1853 m, 22–23.V.2008, HUANG Hao & XU Wang leg.”.
Body length 5.4–6.4 mm; forebody length: 4.1–4.3 mm.
Body (Fig.
Head (Fig.
Pronotum (Fig.
Abdomen narrower than elytra; tergites III-VI with transverse impressions anteriorly. Punctation of these impressions coarse and dense; punctation of remaining surfaces fine and dense; interstices with distinct microsculpture (Fig.
Male. Sternite VII (Fig.
Based on the similar external characters, especially the bicoloured elytra and the male sexual characters, the new species is most similar to R. morvani (Rougemont, 1987) from Nepal, from which it is distinguished by the deeper excision of the male sternite VII, with a more prominently produced centre, longer and denser setae on either side of the excision, and by the longer and narrower apical portion of the aedeagal ventral process.
The species was found in two localities in the Qinling Shan. The specimens were collected by sifting decaying leaf litter in mixed forests at altitudes from ca. 1850 to 2020 m. The paratypes were collected together with R. reticulatus.
The species is named in honor of Hao Huang, one of the collectors of the type material.
