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.展开更多

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.展开更多

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.展开更多
