Male with two tubercles on frons and rostrum (Figs. 1, 2, 5 and 6); shiny; head and rostrum with fine, sparse punctures. In females frons with a shallow fovea (Figs. 3, 4, 7 and 8); the head of female also has a greenishblue tint.</p> <p>Etymology. The specific name is derived from China, the country in which this species was collected.</p> <p>Host Plant. Pinus yunnanensis Franchet.</p> <p>Distribution. Xizang Autonomous Region, China.</p> <p>Discussion. The genus Stereoborus previously contained nine species; those can be distinguished by the above key from each other as well as from S. chinesis. Besides the previous key, also, Voss’s key (Voss 1951) is a good tool for distinguishing the four New Guinean species, S. robustus, S. affinis, S. punctirostris and S. inductus, from the new species, S. chinesis. The other three, S. laporteae, S. interstitialis and S. brevirostris, from Australia are be distinguished from the new species by their length, which ranges between 4.50– 5.00 mm and the new one between 5.44–7.19 mm; as well as their scape either as long as funicle, equal or little longer than funicle and club combined where the scape of the new one is shorter than funicle (Lea 1896 and 1915). The Indonesian species, S. monticola, has tibia wide, cuneiform, and with interior margin dentate and concave (Voss 1957) where S. chinensis has a normal tibia. The Samoan species, S. binodifrons, is distinguished by its stria 10 with a carina below it and its mesepimeron impressed on its posterior half and with a trace of shallow punctures along the anterior edge of the impression (Marshall 1921) which those characters are absent in the new species.</p> </div>	https://treatment.plazi.org/id/550087CA6334843F9F44FB45FC33FECD	Public Domain	No known copyright restrictions apply.
