The Tachinidae of mainland China and Taiwan (generally referred to as China herein for brevity) are catalogued. A total of 1109 valid species are recorded of which 403 species (36%) are recorded as endemic. Distributions within China are given according to the 33 administrative divisions of the country, and distributions outside China are given according to a scheme of geographical divisions developed for this catalogue and most finely divided for the Palaearctic and Oriental Regions. The catalogue is based on examination of the primary literature comprising about 670 references and also includes a small number of records based on unpublished data from specimens examined in collections. Taxa are arranged hierarchically under the categories of subfamily, tribe, genus, subgenus (where recognized), and species. Nomenclatural details are provided for nominal genera and species. This includes synonyms at both levels for taxa described or recorded from China. For valid species, distributions are provided along with complete name-bearing type data for associated names. Additional information is given in the form of notes, numbering more than 300 in the catalogue section and about 50 in the references section. Six genera are newly recorded from China: Calliethilla Shima (Ethillini), Chetoptilia Rondani (Dufouriini), Demoticoides Mesnil (Leskiini), Pseudalsomyia Mesnil (Goniini), Redtenbacheria Schiner (Eutherini), and Rutilia Robineau-Desvoidy (Rutiliini). Fourteen species are newly recorded from China: Actia solida Tachi & Shima, Atylostoma towadensis (Matsumura), Chetoptilia burmanica (Baranov), Demoticoides pallidus Mesnil, Dexiosoma lineatum Mesnil, Feriola longicornis Mesnil, Frontina femorata Shima, Phebellia laxifrons Shima, Prodegeeria gracilis Shima, Prooppia stulta (Zetterstedt), Redtenbacheria insignis Egger, Sumpigaster subcompressa (Walker), Takanomyia frontalis Shima, and Takanomyia rava Shima. Two genera and 23 species are recorded as misidentified from China. New names are proposed for three preoccupied names: Pseudodexilla O’Hara, Shima & Zhang, nomen novum for Pseudodexia Chao, 2002; Admontia longicornalis O’Hara, Shima & Zhang, nomen novum for Admontia longicornis Yang & Chao, 1990; and Erythrocera neolongicornis O’Hara, Shima & Zhang, nomen novum for Pexopsis longicornis Sun & Chao, 1993. New type species fixations are made under the provisions of Article 70.3.2 of ICZN (1999) for 13 generic names: Chetoliga Rondani, Discochaeta Brauer & Bergenstamm, Erycina Mesnil, Eurigaster Macquart, Microvibrissina Villeneuve, Oodigaster Macquart, Plagiopsis Brauer & Bergenstamm, Prooppia Townsend, Ptilopsina Villeneuve, Ptilotachina Brauer & Bergenstamm, Rhinotachina Brauer & Bergenstamm, Schaumia Robineau-Desvoidy, and Setigena Brauer & Bergenstamm. Subgenus Tachina (Servillia Robineau-Desvoidy) is reduced to a synonym of subgenus Tachina (Tachina Meigen). The valid names of two species are reduced to nomina nuda and replaced by other available names with new status as valid names: Siphona (Aphantorhaphopsis) perispoliata (Mesnil) replaces S. (A.) mallochiana (Gardner), and Zenillia terrosa Mesnil replaces Z. grisellina (Gardner). The following 12 new combinations are proposed: Carcelina shangfangshanica (Chao & Liang), Drino (Drino) interfrons (Sun & Chao), Drino (Zygobothria) hirtmacula (Liang & Chao), Erythrocera longicornis (Sun & Chao) (a preoccupied name and replaced with Erythrocera neolongicornis O’Hara, Shima & Zhang, nomen novum), Isosturmia aureipollinosa (Chao & Zhou), Isosturmia setamacula (Chao & Liang), Isosturmia setula (Liang & Chao), Paratrixa flava (Shi), Phryno jilinensis (Sun), Phryno tibialis (Sun), Prosopodopsis ruficornis (Chao), and Takanomyia parafacialis (Sun & Chao). The following 19 new synonymies are proposed: Atylomyia chinensis Zhang & Ge with Tachina parallela Meigen (current name Bessa parallela), Atylomyia minutiungula Zhang & Wang with Ptychomyia remota Aldrich (current name Bessa remota), Carcelia (Carcelia) hainanensis Chao & Liang with Carcelia rasoides Baranov, Carcelia frontalis Baranov with Carcelia caudata Baranov, Carcelia hirtspila Chao & Shi with Carcelia (Parexorista) delicatula Mesnil (current name Carcelia (Euryclea) delicatula), Carcelia septima Baranov with Carcelia octava Baranov, Carcelia (Senometopia) dominantalis Chao & Liang with Carcelia quarta Baranov (current name Senometopia quarta), Carcelia (Senometopia) maculata Chao & Liang with Carcelia octava Baranov, Drino hersei Liang & Chao with Sturmia atropivora RobineauDesvoidy (current name Drino (Zygobothria) atropivora), Eucarcelia nudicauda Mesnil with Carcelia octava Baranov, Isopexopsis Sun & Chao with Takanomyia Mesnil, Mikia nigribasicosta Chao & Zhou withBombyliomyia apicalis Matsumura (current name Mikia apicalis), Parasetigena jilinensis Chao & Mao with Phorocera (Parasetigena) agilis takaoi Mesnil (current name Parasetigena takaoi), Phebellia latisurstyla Chao & Chen with Phebellia latipalpis Shima (current name Prooppia latipalpis), Servillia linabdomenalis Chao with Servillia cheni Chao (current name Tachina (Tachina) cheni), Servillia planiforceps Chao with Tachina sobria Walker, Spiniabdomina Shi with Paratrixa Brauer & Bergenstamm, Tachina kunmingensis Chao & Arnaud with Tachina sobria Walker, and Thecocarcelia tianpingensis Sun & Chao with Drino (Isosturmia) chatterjeeana japonica Mesnil (current name Isosturmia japonica).

It is a land of physical and ecological extremes: southern subtropical and tropical forests, richly diverse southwestern mountains, towering Himalayas, harsh and inhospitable Tibetan Plateau, western Tien Shan range, dry Taklimakan and Goli Deserts, northeastern temperate broadleaf and coniferous forests, and eastern fertile plains and lesser mountains. Along its southern and western borders are portions of four of the world’s 34 “biodiversity hotspots”, places recognized by Conservation International for their high endemicity and threatened habitat. These are the Indo-Burma hotspot, Mountains of Southwest China hotspot (particularly Hengduan Shan), Himalaya hotspot, and Mountains of Central Asia hotspot (represented in China by Tien Shan) (http:// www.biodiversityhotspots.org). These biodiversity hotspots, and other biodiverse places in China, have given rise to an endemic fauna and flora of significant size. In the plant world, for example, the Hengduan Shan is known as the hotbed of Rhododendron evolution with about 230 species. Among the vertebrates are such Chinese endemics as the giant panda (Ailuropoda melanoleuca), golden monkeys (Rhinopithecus spp.), baiji (Lipotes vexillifer), and brown eared pheasant (Crossoptilon mantchuricum). Less conspicuous, but many times more numerous in species, are the endemic invertebrates that have evolved within present-day China. Biogeographically, China is unique among the countries of the world in lying at the crossroads of the Palaearctic and Oriental Regions. Hence, for most groups of organisms, the species of China consist of a combination of Palaearctic, Oriental, and endemic elements. This is true also of the Tachinidae of China. The Tachinidae are one of the largest families of Diptera with almost 10,000 described species and many thousands of undescribed species (Stireman et al. 2006). The family is correspondingly diverse in China, but because the Chinese tachinid fauna is still in a period of discovery and study, it must be significantly larger than the numbers given here might suggest. We record 1109 species and 257 genera of Tachinidae from mainland China and Taiwan, the former number representing about 11% of the world’s described tachinid species. From mainland China we record 1040 species, which compares to 754 and 832 species recorded from the same area by Chao et al. (1998) and Hua (2006), respectively. Our higher number is partly a reflection of species described from China since those works, or described from elsewhere and recently recognized from China, but a significant number of species were presumably overlooked by Chao et al. (1998) and Hua (2006) in the voluminous literature that exists on Chinese insects. The Chinese tachinid fauna has very few endemic genera and none of significant size, but has 403 species recorded as endemic to China plus Taiwan. This represents 36% of the total tachinid fauna. We record 343 species as endemic to mainland China and 32 species as endemic to Taiwan. The total number of species recorded from Taiwan is 231; some of these species are shared with the Oriental Region but not with mainland China.

Tachinid flies are natural enemies of many lepidopteran and coleopteran pests of forests, crops, and fruit trees. In order to address the lack of genetic data in this economically important group, we sequenced the complete mitochondrial genome of the Palaearctic tachinid fly Elodia flavipalpis Aldrich, 1933. Usually found in Northern China and Japan, this species is one of the primary natural enemies of the leaf-roller moths (Tortricidae), which are major pests of various fruit trees. The 14,932-bp mitochondrial genome was typical of Diptera, with 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes. However, its control region is only 105 bp in length, which is the shortest found so far in flies. In order to estimate dipteran evolutionary relationships, we conducted a phylogenetic analysis of 58 mitochondrial genomes from 23 families. Maximum-likelihood and Bayesian methods supported the monophyly of both Tachinidae and superfamily Oestroidea. Within the subsection Calyptratae, Muscidae was inferred as the sister group to Oestroidea. Within Oestroidea, Calliphoridae and Sarcophagidae formed a sister clade to Oestridae and Tachinidae. Using a Bayesian relaxed clock calibrated with fossil data, we estimated that Tachinidae originated in the middle Eocene.

Industrial internet of unmanned aerial vehicles (IIoUAVs) which enable autonomous inspection and measurement of anything anytime anywhere have become an essential component of the future industrial internet of things (IIoT) ecosystem. In this paper, we investigate how to apply IIoUAVs for power line inspection in smart grid from an energy efficiency perspective. Firstly, the energy consumption minimization problem is formulated as a joint optimization problem, which involves both the large-timescale optimization such as trajectory scheduling, velocity control, and frequency regulation, and the small-timescale optimization such as relay selection and power allocation. Then, the original NP-hard problem is transformed into a two-stage suboptimal problem by exploring the timescale difference and the energy magnitude difference between the large-timescale and the small-timescale optimizations, and is solved by combining dynamic programming (DP), auction theory and matching theory. Finally, the proposed algorithm is verified based on real-world map and realistic power grid topology.
