A W-Mo mineralized region is located along the northern margin of the South Qinling tectonic belt of China. WMo mineralization occurs mainly in Cambrian–Ordovician clastic and carbonate rocks, and the ore bodies are structurally controlled by NW–SE-and NNE–SSW-striking faults. Evidence for magmatism in the area is widespread and is dominated by intermediate–felsic intrusives or apophyses, such as the Dongjiangkou, Yanzhiba, Lanbandeng, and Sihaiping granitic bodies. Quartz-vein-type mineralization and fault-controlled skarn-type mineralization dominate the ore systems, with additional enrichment in residual deposits. At present, there are few or insufficient studies on(1) the age of mineralization,(2) the relationship between intermediate–felsic granite and W-Mo mineralization,(3) the source of ore-forming materials, and(4) the metallogenic and tectonic setting of the mineralized area. In this paper, we present geochronology results for numerous intrusive granitic bodies in the South Qinling tectonic belt. U-Pb zircon geochronology of the Lanbandeng monzogranite and Wangjiaping biotite monzogranite yields ages of 222.7 ± 2.3 and 201.9 ± 1.8 Ma, respectively. In contrast to the Late Triassic age of the Lanbandeng monzogranite, the age of the newly discovered Wangjiaping biotite monzogranite places it at the Triassic–Jurassic boundary. Re-Os molybdenite geochronology on the Qipangou W-Mo deposit yielded a model age of 199.7 ± 3.9 Ma, indicating the deposit formed in the early Yanshanian period of the Early Jurassic. Granitoid intrusions in the mineralized area are characterized by composite granite bodies that crystallized at ca. 240–190 Ma. While there were multiple stages of intrusion, most occurred at 210–220 Ma, with waning magmatic activity at 200–190 Ma. The Re-Os age of molybdenite in the region is ca. 200–190 Ma, which may represent a newly discovered period of W-Mo metallogenesis that occurred during the final stages of magmatism.

Modem grylloblattids are one of the least diverse insect orders. The single extant family is contrasted with 46 families described from the fossil records, which extend to the Late Carboniferous. The most ancient grylloblattid nymphs are known from the Lower Permian. Till now, there is no report on grylloblattid from Burmese amber, which is a very old amber locality. Herein, we describe Sylvalitoralis cheni Zhang, Bai ＆ yang, sp. nov. from Grylloblattina based on a nymph specimen from the mid-Cretaceous Myanmar （Burmese） amber.

The extinct new species, Chresmoda chikuni Zhang ＆ Ge, sp. nov. is described from the Mid-Cretaceous amber from northern Myanmar. This amber insect exhibits a very peculiar combination of derived characters like strongly elongated, free coxa, non-clawed pretarsus. The type specimens are deposited in the Three Gorges Entomological Museum, Chongqing, China.

Scarabaeinae is a globally distributed coprophagous coleopteran group with southeast Asia and Africa as the key areas of distribution. Located in the southern part of China, Hong Kong has subtropical climate and diverse habitats supporting a high diversity of scarabaeines. This paper gives a detailed review on Scarabaeinae from Hong Kong, including the new records to Hong Kong, photographic records of type specimens from Hong Kong, and identification keys to genera and species. A total of 13 genera and 51 species of scarabaeines were recorded in Hong Kong. Among them, 14 species were new records to Hong Kong found in the authors＇ recent surveys, viz. Caccobius（Caccophilus） brevis Waterhouse, 1875, Copris（s. str.） punctatus Gillet, 1910, C.（s. str.） szechouanicus Balthasar, 1958, Microcopris propinquus Felsche, 1910, Onitis excavatus Arrow, 1931, Oni. intermedius Frivaldszky, 1892, Oni. subopacus Arrow, 1931, Onthophagus brutus Arrow, 1931, Ont. tricolor Boucomont, 1914, Ont.（Matashia） lenzi Harold, 1874, Ont.（s. str.） roubali Balthasar, 1935, Ont.（Parascatonomus） horni Balthasar, 1935, Scarabaeus（Kheper） erichsoni Harold, 1867 and Sisyphus（s. str.） indicus Hope, 1831. Onthophagus（Paraphanaeomorphus） trituber jacobsoni Kabakov, 2006 was found to be a new synonym of the nominate subspecies. Catharsius davidis Deyrolle ＆ Fairmaire, 1878 and Copris davidis（Deyrolle ＆ Fairmaire, 1878） were found to be the new synonyms of Catharsius molossus（Linnaeus, 1758）. Hong Kong was also the only locality where Liatongus pugionatus and Onthophagus convexicollis were recorded over the world.

Geometric morphometrics （GM） is an important method of shape analysis and increasingly used in a wide range of scientific disciplines. Presently, a single character comparison system of geometric morphometric data is used in almost all empirical studies, and this approach is sufficient for many scientific problems. However, the estimation of overall similarity among taxa or objects based on multiple characters is crucial in a variety of contexts （e.g. （semi-）automated identification, phenetic relationships, tracing of character evolution, phylogenetic reconstruction）. Here we propose a new web-based tool for merging several geometric morphometrics data files from multiple characters into a single data file. Using this approach information from multiple characters can be compared in combination and an overall similarity estimate can be obtained in a convenient and geometrically rigorous manner. To illustrate our method, we provide an example analysis of 25 dung beetle species with seven Procrustes superimposed landmark data files representing the morphological variation of body features： the epipharynx, right mandible, pronotum, elytra, hindwing, and the metendosternite in dorsal and lateral view. All seven files were merged into a single one containing information on 649 landmark locations. The possible applications of such merged data files in different fields of science are discussed.
