Project description:The monotypic genus Buobellenden Yin & Nomura, 2009 is placed as a junior synonym of Bellenden Chandler, 2001. This act results in Bellenden jingyuanensis (Yin & Nomura), comb. n. (from Buobellenden). A new species, Bellenden siguniang Yin & Jang, sp. n., collected from the alpine area in Sichuan, SW China, is described, illustrated, and distinguished from all congeners. A new illustration of the aedeagus of Buobellenden jingyuanensis is given.
Project description:An increased incidence of thyroid cancer has been reported in the area close to Mount Etna, the largest volcano in Europe located in Northeastern Sicily. We tested the hypothesis that exposure to the emissions from the volcano is associated with thyroid cancer in 186 municipalities from three provinces surrounding the volcano (1.9 million inhabitants). We measured the angle between the bearing of the municipalities and each direction, with special focus on South-East, the prevalent direction of the plume, and conducted a regression analysis on 2003-2016 incidence rates of thyroid cancer, adjusting for distance from Mount Etna, population size, and income. A 10-degree increase in the angle with South-East was associated with a decrease in thyroid cancer rates in the whole population (- 0.67 cases/100,000, p = 0.002) and in women (- 1.54/100,000, p < 0.001), and were robust to several sensitivity analyses. Similar results were obtained for East-South-East direction. These results support the hypothesis of a potential role of exposure to the plume from Mount Etna in determining the high rates of thyroid cancer. The results need to be confirmed in analytical studies, in which information of exposure to chemicals originating from the volcano, as well as other possible causes, should be carefully measured, molecular characteristics of the tumors and taken into account.
Project description:Two new species of the tyrine genus Megatyrus Hlaváč & Nomura, Megatyrus schuelkei Yin & Li, sp. n. (based on two males) and Megatyrus tengchongensis Yin & Li, sp. n. (based on one female), from Yunnan, Southwest China are described, illustrated and distinguished from allied species. The body size, form of maxillary palpi, male and female genital structures, and distributional patterns are used to separate the new species.
Project description:This paper is the first of a series that deals with Dr. Michael Schülke's collection of Pselaphinae from China. The tyrine genera Labomimus Sharp, Linan Hlaváč and Pselaphodes Westwood are chosen for the first part. The study revealed fourteen new species, all described and illustrated: Labomimus cognatus Yin & Li, sp. n. (Yunnan), Labomimus dabashanus Yin & Li, sp. n. (Hubei, Shaanxi), Labomimus mirus Yin & Li, sp. n. (Yunnan), Labomimus paratorus Yin & Li, sp. n. (Shaanxi), Labomimus sarculus Yin & Li, sp. n. (Yunnan), Labomimus schuelkei Yin & Li, sp. n. (Shaanxi), Labomimus vespertilio Yin & Li, sp. n. (Yunnan), Linan tendothorax Yin & Li, sp. n. (Yunnan), Pselaphodes distincticornis Yin & Li, sp. n. (Yunnan), Pselaphodes erlangshanus Yin & Li, sp. n. (Sichuan), Pselaphodes flexus Yin & Li, sp. n. (Yunnan), Pselaphodes tibialis Yin & Li, sp. n. (Yunnan), Pselaphodes venustus Yin & Li, sp. n. (Yunnan) and Pselaphodes zhongdianus Yin & Li, sp. n. (Yunnan). Pselaphodes jizushanus Yin, Li & Zhao is recorded from a new locality in Yunnan and its aedeagus is newly illustrated; new province records for Pselaphodes nomurai Yin, Li & Zhao is provided. Labomimus torus (Yin, Li & Zhao), comb. n. is moved from Pselaphodes after an examination of the holotype. Species represented only by unassociated females are listed with label data.
Project description:A new distinctive species of the rare Oriental goniacerine genus Awas Löbl, Awas gigas sp. n., is described and illustrated, based on three males and fourteen females taken at the Daoyao Shan Natural Reserve in the southern Chinese province of Guangxi. All specimens were collected from colonies of the ant genus Pachycondyla F. Smith nesting in decomposing woods.
Project description:Tangius indicus sp. n. (Batrisitae: Batrisini) is described and illustrated from the Indian States of Meghalaya (Khasi Hills, type locality) and West Bengal (Darjeeling). Specimens of the new species are similar to those of the recently described T. glabellus Yin & Li from Tibet, Southwest China, and can be separated only by minor differences of the male features.
Project description:A total of three Chinese species of the genus Intestinarius Kurbatov, 2007 are recognized, among which, two new species are described: Intestinarius guangdongensissp. n. from Guangdongand Intestinarius longicepssp. n. from Guizhou. Illustrations of major diagnostic characters are given for all three Chinese species including Intestinarius kuzmini Kurbatov, 2007. A key is included to aid in their identification.
Project description:Two new species of the genus Horniella Raffray are described from China: Horniellaaculeata sp. n. (Yunnan Province) and Horniellajinggangshana sp. n. (Jiangxi Province). Horniellanakhi Yin & Li is recorded from a new locality. Three potentially new species from Myanmar and China, each represented by female specimen(s) only, are left unnamed. Their collecting data are given, and the genital complex figured for future comparison.
Project description:Three new species of the ant-loving beetle tribe Batrisini, Reitter, 1882 (Pselaphinae: Batrisitae) from southeast Xizang, China are described: Arthromelodeslhunzensis sp. nov., Tribasoditesliangi sp. nov., and Tribasoditesyumaicus sp. nov. Illustrations of the habitus and diagnostic features of these species are provided to aid identification. With these additions, the number of batrisine species known from Xizang increases to 83.
Project description:A new species of the genus Tychobythinus Ganglbauer, 1896, Tychobythinusoculatus sp. n., is described from near Köyceğiz, Muğla Province, in southwestern Turkey. The new species is morphologically closely related to Tychobythinusabnormipes Reitter, 1910, and Tychobythinuspauper Kiesenwetter, 1858, but can be readily distinguished from both by having very simplified internal armature of the aedeagus, and by the specific shape of the gular depression.
