The widely distributed and species diverse genus Cloeon Leach, 1815 has never been reviewed in China, although nine species names have been reported from this country. After checking types of two species (C. viridulum and C. apicatum) and newly collected materials from more than 50 sites, four species are recognized, compared, and photographed in this research. Among them, the species C. bicolor Kimmins, 1947 is first recorded in China, and its nymphs are described for the first time. The distribution in China of two other species (C. dipterum (Linnaeus, 1761) and C. harveyi (Kimmins, 1947)) are also confirmed. The two species established by Navás (C.apicatum Navás, 1933 = C. navasi Bruggen, 1957, C. pielinum Navás, 1933, syn. nov.) and the species C. micki named by Tong and Dudgeon in 2021 are synonymized with C. viridulum Navás, 1931—the fourth species in this study. Furthermore, the C. virens Klapálek, 1905 from the Chinese mainland, found by Ulmer in 1925, is also regarded as the last species. Among the four species, the C. dipterum and C. harveyi seem closer because of the similar female color patterns of their stigma and ventral abdomen, while the species C. viridulum and C. bicolor are more alike because they have neither pigmented stigma nor stripes on abdominal sterna.

A new empoascine genus, Membranacea Qin & Zhang, gen. n., with three new species (M. spinata Qin & Zhang, sp. n., M. unijugata Qin & Zhang, sp. n. and M. plana Qin & Zhang, sp. n.), from China are described. In addition, the genus Bhatasca Dworakowska, 1995 is newly recorded from the Chinese mainland and a new species, B. rectangulata Qin & Zhang, sp. n., is described. The genus Ghauriana Thapa, 1985 is reported for the first time from China and a new species, G. sinensis Qin & Zhang sp. n. is added to the Chinese typhlocybine fauna. Keys to all species in each genus are given. Habitus photos and illustrations of male genitalia of these new species are also provided.

The genus Philorus is newly recorded from the Chinese mainland. One species, Philorus levanidovae Zwick, is recordedfrom China for the first time. Another species, Philorus emeishanensis sp. nov., is described as new to science. The genus Philorus is discussed and a key to the known species from China is presented.

The genus Sorolopha Lower from the Chinese Mainland is reviewed. Seventeen species are recognized, including two new species, S. dactyloidea sp. n. and S. identaeolochloca sp. n., and five species previously unrecorded from China, S. asphaeropa Diakonoff, 1973, S. ferruginosa Kawabe, 1989, S. karsholti Kawabe, 1989, S. liochlora (Meyrick, 1914), and S. stygiaula (Meyrick, 1933). Also, the female of S. ferruginosa is reported for the first time with a brief description and illustration. Sorolopha longurus Liu & Bai, 1982 (syn. n.) and S. micheliacola Liu, 2001 (syn. n.) are proposed as new synonyms of S. camarotis (Meyrick, 1936), and S. chlorotica Liu & Bai, 1985 (syn. n.) as a new synonym of S. rubescens Diakonoff, 1973. Photographs of adults and genitalia of the new species are provided. A key to the species from the Chinese Mainland is given based on the male genitalia.

AbstractA dataset entitled “A potential risk index dataset for landfalling tropical cyclones over the Chinese mainland” (PRITC dataset V1.0) is described in this paper, as are some basic statistical analyses. Estimating the severity of the impacts of tropical cyclones (TCs) that make landfall on the Chinese mainland based on observations from 1401 meteorological stations was proposed in a previous study, including an index combining TC-induced precipitation and wind (IPWT) and further information, such as the corresponding category level (CAT_IPWT), an index of TC-induced wind (IWT), and an index of TC-induced precipitation (IPT). The current version of the dataset includes TCs that made landfall from 1949–2018; the dataset will be extended each year. Long-term trend analyses demonstrate that the severity of the TC impacts on the Chinese mainland have increased, as embodied by the annual mean IPWT values, and increases in TCinduced precipitation are the main contributor to this increase. TC Winnie (1997) and TC Bilis (2006) were the two TCs with the highest IPWT and IPT values, respectively. The PRITC V1.0 dataset was developed based on the China Meteorological Administration’s tropical cyclone database and can serve as a bridge between TC hazards and their social and economic impacts.

The official method of collecting county-level GDP values in the Chinese Mainland relies mainly on administrative reporting data and suffers from high costs of time, money, and human labor. To date, a series of studies have been conducted to generate fine-grained maps of socioeconomic indicators from the easily accessed remote sensing data and achieved satisfactory results. This paper proposes a transfer learning framework that regards nightlight intensities as a proxy of economic activity degrees to estimate county-level GDP around the Chinese Mainland. In the framework, paired daytime satellite images and nightlight intensity levels were applied to train a VGG-16 architecture, and the output features at a specific layer, after dimensional reduction and statistics calculation, were fed into a simple regressor to estimate county-level GDP. We trained the model with data of 2017 and utilized it to predict county-level GDP of 2018, achieving an R-squared of 0.71. Furthermore, the results of gradient visualization confirmed the validity of the proposed framework qualitatively. To the best of our knowledge, this is the first time that county-level GDP values around the Chinese Mainland have been estimated from both daytime and nighttime remote sensing data relying on attention-augmented CNN. We believe that our work will shed light on both the evolution of fine-grained socioeconomic surveys and the application of remote sensing data in economic research.

Fourteen species of Phaecasiophora Grote from the Chinese Mainland are treated, including five new species (P. supparallelica sp. n., P. levis sp. n., P. curvicosta sp. n., P. lushina sp. n., and P. similithaiensis sp. n.) and three new species records for China. Phaecasiophora leechi is transferred from subgenus Megasyca to subgenus Phaecasiophora, and a new synonym of it, viz. P. obligata Kawabe, is proposed. Photographs of the adults, genitalia of the new species, and the species with new synonyms are provided. A key to the species from the Chinese Mainland based on genitalia is given.
