A new genus of Chinese Empoascini (Hemiptera: Cicadellidae: Typhlocybinae), Radicafurcus Qin & Zhang, gen. n. with one new species, R. breviprocessus Qin & Zhang, sp. n. from Sichuan Province (S.W. China) is described and illustrated. Baguoidea Mahmood 1967 is redescribed and a new species, B. yunnanensis Qin & Zhang, sp. n. is described from Yunnan Province (S.W. China). Two genera (Faiga Dwor...

Pinus densata Mast. is considered a homoploid hybrid species that originated from the putative parent tabuliformis Carr. and yunnanensis Franch., but mechanism of adaptive differentiation P. its parents in native habitats has not been reported. Therefore, overlapping distribution areas between heart Hengduan Mountains were chosen. The hybrids their with respect to elevational gradient was studi...

Heliotropium foliatum and Tournefortia humilis are transferred to Euploca Nutt. respectively as Euploca foliata comb. n. and Euploca humilis comb. n. A collection from Guyana has been recently identified as Euploca humistrata, a species previously considered a Brazilian endemic. A collection from French Guiana documents for the first time the species in that country. A key to the species of the...

Corylus yunnanensis (Franch.) A. Camus is a deciduous shrub, native to the Hengduan Mountain of Qinghai–Tibetan Plateau, and an economically ecologically important woody crop species. In present study, one hundred fifty trees sampled from ten populations C. in Sichuan Province were investigated assess population genetic variation using nine SSR markers. The results revealed that has average val...

Cimyunnins A-C (1-3), characterized with an unusual fused cyclopentenone ring G, together with cimyunnin D (4), possessing a highly rearranged γ-lactone ring F, were characterized from the fruit of Cimicifuga yunnanensis. Their structures were elucidated by spectroscopic analysis, X-ray diffraction, and density functional theory calculations. In addition, cimyunnin A exhibited comparable anti-a...

Trischidocera Villeneuve, 1915 includes two species, T. sauteri Villeneuve, 1915 (Taiwan and Malaysia) and T. yunnanensis Chao & Zhou, 1987 (China). The systematic placement of Trischidocera has been controversial. It was originally placed within the "Thryptoceratidae" (= "Actiidae"), then moved to Germariini, then considered an unplaced Tachinidae, and more recently placed in Ormiini. Here, th...

Graphis yunnanensis is described here as a new species. It is taxonomically well characterized by entire labia, slit-like disc, lateral thalline margin, completely carbonized proper exciple, inspersed hymenium, 8-spored asci, muriform 25~45 × 8~12 µm ascospores, and the presence of norstictic and stictic acids. The separation of the new species from other somewhat similar Graphis species is dis...
