Viet Nam's population was over 96.2 million on 1 April 2019, national census, ranking 15 th most populous country in the world and the third in Southeast Asia. The country is in a sub-tropical region with the main product of agriculture activities and is rich in fruits and vegetables that have been believed to protect against many cancer sites including the stomach. Both fruits and vegetables are rich in micronutrients and contain antioxidants to prevent cancer risks (Chakraborty et al., 2020). Fruits probably protect against stomach cancer (WCRF, 2007). However, only about one third of study participants have a daily intake of fruits and vegetables due to limited knowledge, attitude, and practice of cancer presentation by healthy diet (Falah Asadi et al., 2018). Therefore, more studies on the benefit intake of these organic natural foods are needed. In contrast, the ecological analysis of current by alcohol usage by compared two populations of Japan (high incidence of stomach cancer) and Thailand (low incidence of this cancer) has found that proportion of study participants in Japan (35%) was significantly higher than in Thailand (2.7%) (Pittayanon et al., 2018).Among non-communicable diseases occurrences in

In this paper we revise the species of the Neoserica calva group from continental South East Asia, which was so far known only from China. Here we describe 11 new species from Laos, Thailand, and Vietnam: Neoserica allosigillata Ahrens & Pham, new species, N. axelkalliesi Ahrens & Pham, new species, N. chetaoensis Ahrens & Pham, new species, N. diplospinosa Ahrens & Pham, new species, N. fragilis Ahrens & Pham, new species, N. ihlei Ahrens & Pham, new species, N. judsoni Ahrens & Pham, new species, N. peregovitsi Ahrens & Pham, new species, N. rufoplagiatoides Ahrens & Pham, new species, N. sharkeyi Ahrens & Pham, new species, and N. tramton Ahrens & Pham, new species.

VIETBIO [Innovative approaches to biodiversity discovery and characterisation in Vietnam] is a bilateral German-Vietnamese research and capacity building project focusing on the development and transfer of new methods and technology towards an integrated biodiversity discovery and monitoring system for Vietnam. Dedicated field training and testing of innovative methodologies were undertaken in Cuc Phuong National Park as part and with support of the project, which led to the new biodiversity data and records made available in this article collection. VIETBIO is a collaboration between the Museum für Naturkunde Berlin – Leibniz Institute for Evolution and Biodiversity Science (MfN), the Botanic Garden and Botanical Museum, Freie Universität Berlin (BGBM) and the Vietnam National Museum of Nature (VNMN), the Institute of Ecology and Biological Resources (IEBR), the Southern Institute of Ecology (SIE), as well as the Institute of Tropical Biology (ITB); all Vietnamese institutions belong to the Vietnam Academy of Science and Technology (VAST). The article collection "VIETBIO" (https://doi.org/10.3897/bdj.coll.63) reports original results of recent biodiversity recording and survey work undertaken in Cuc Phuong National Park, northern Vietnam, under the framework of the VIETBIO project. The collection consist of this “main” cover paper – characterising the study area, the general project approaches and activities, while also giving an extensive overview on previous studies from this area – followed by individual papers for higher taxa as studied during the project. The main purpose is to make primary biodiversity records openly available, including several new and interesting findings for this biodiversity-rich conservation area. All individual data papers with their respective primary records are expected to provide useful baselines for further taxonomic, phylogenetic, ecological and conservation-related studies on the respective taxa and, thus, will be maintained as separate datasets, including separate GUIDs also for further updating.

Three new species of the genus Miridiba Reitter, 1902 from Vietnam are described and illustrated: Miridiba apicespinosa P.V. Pham & Keith, new species, M. ngoclinhensis P.V. Pham & Keith, new species, and M. quangnamensis P.V. Pham & Keith, new species. Miridiba bannaensis Gao & Fang, 2018 is reported for the first time from Vietnam. Additionally, an updated checklist and a key to all Vietnamese species are provided.

Here we present an overview of the species of the genus Amiserica Nomura, 1974. The taxonomy of the species of eastern Asia (China and adjacent regions) is revised herein, which so far have not been treated yet. Twenty-eight species are discovered new to science: Amiserica basisymmetrica Ahrens, Fabrizi & Liu, new species, A. belousovi Ahrens, Fabrizi & Liu, new species, A. carolusholzschuhi Ahrens, Fabrizi & Liu, new species, A. diaocangshana Ahrens, Fabrizi & Liu, new species, A. eucurviforceps Ahrens, Fabrizi & Liu, new species, A. fengyangensis Ahrens, Fabrizi & Liu, new species, A. funiushanica Ahrens, Fabrizi & Liu, new species, A. gibbosiforceps Ahrens, Fabrizi & Liu, new species, A. guanmenshanica Ahrens, Fabrizi & Liu, new species, A. guizhouensis Ahrens, Fabrizi & Liu, new species, A. gulinqin Ahrens, Fabrizi & Liu, new species, A. incisa Ahrens, Fabrizi & Liu, new species, A. jiuhuensis Ahrens, Fabrizi & Liu, new species, A. jizuensis Ahrens, Fabrizi & Liu, new species, A. linzhouensis Ahrens, Fabrizi & Liu, new species, A. longxinensis Ahrens, Fabrizi & Liu, new species, A. lucidiflava Ahrens, Fabrizi & Liu, new species, A. nahang Ahrens, Fabrizi & Liu, new species, A. panghongae Ahrens, Fabrizi & Liu, new species, A. pappi Ahrens, Fabrizi & Liu, new species, A. piaoac Ahrens, Fabrizi & Liu, new species, A. pseudoantennalis Ahrens, Fabrizi & Liu, new species, A. pseudoincisa Ahrens, Fabrizi & Liu, new species, A. sacculiforceps Ahrens, Fabrizi & Liu, new species, A. strnadi Ahrens, Fabrizi & Liu, new species, A. ventriscalptus Ahrens, Fabrizi & Liu, new species, A. venxianensis Ahrens, Fabrizi & Liu, new species, A. zhongtiaoshanensis Ahrens, Fabrizi & Liu, new species. Furthermore, our investigation resulted in two new combinations: Maladera (Eumaladera) loi (Kobayashi, 1991), new combination and Amiserica antennalis (Nomura, 1974), new combination; the first species is thus excluded from Amiserica. A key to species groups and species within groups is given, habitus and male genitalia are illustrated. The distribution of the species revised herein is shown on maps.
