A new species of Zonstein, 1987 (Araneae, Nemesiidae) from Fujian, China.

Background: The genus Zonstein, 1987 comprises 66 species, distributed across regions from East Asia to the Caucasus, with about 20 species recorded from China. According to Zonstein et al. (2018) and Zonstein (2024), members of can be identified by the presence of two to three retroventral megaspines arranged sequentially on tibia I in males and paired spermathecae in females, each bearing two-branched heads or a lateral diverticulum.

A new species of Huber, 2005 (Araneae, Pholcidae) from Jiangxi Qiyunshan National Nature Reserve, southern China.

Background: Huber, 2005 contains 52 species distributed in Cambodia, China, Laos, Thailand and Vietnam, out of which about 34 species have been recorded from China. It can be distinguished from all other genera of Pholcidae by the male chelicerae with lateral ledges and the cheliceral apophyses with cuticular ridges or scales. The femur of the male palp features a retrolateral apophysis.

A Trade-Off Between Leaf Carbon Economics and Plant Size Among Mangrove Species in Dongzhaigang, China.

Plant size is closely linked to its leaf trait characteristics, which are essential for determining its form and function. These relationships constitute a fundamental component of the global spectrum of plant diversity. Despite this, the size-trait relationships in coastal mangroves have often been overlooked, with a common assumption that they would mirror those found in terrestrial tropical trees.

Heterospecific pollen avoidance strategy prevails in the generalized plant-pollinator network on Yongxing Island.

Heterospecific pollen (HP) deposition varies widely among species in communities, which has been explicated by two adaptation strategies: HP avoidance and HP tolerance. Studies of the plant-pollinator network have uncovered that oceanic island communities are highly generalized and strongly connected. It remains unclear, however, which strategy prevails in such communities.

Host relationships and biological notes of Cassidinae beetles (Coleoptera, Chrysomelidae) in Qiannan Prefecture, Guizhou, China.

The faunal composition, host relationships and biological information of the subfamily Cassidinae (Coleoptera, Chrysomelidae) remain poorly known in many Chinese regions. Based on the seven-year field survey, faunal composition and host associations of Cassidinae beetles were systematically compiled for Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. In particular, through direct field observations, detailed biological information, such as life history and behavioural features and host plants were first recorded for 56 species of Cassidinae beetles.

A new troglobitic species of the genus Zhao & S. Li, 2019 (Araneae, Agelenidae, Coelotinae) from Guizhou, China.

Background: Zhao & S. Li, 2019 is the only known genus of Coelotinae of which all species have deep morphological adaptations to the subterranean environment, such as depigmentation of body, degenerated or absent eyes and, frequently, with attenuated bodies and/or appendages. Four species of have been reported from Guizhou Province, China.

A new species of Simon, 1887 from Baiyan Cave in Guizhou Province, China (Araneae, Linyphiidae).

Zhou & Xu, (♂♀) is the first species in the genus to be described from Baiyan Cave in Guizhou Province, China. The new species is similar to Zhu, Chen & Sha, 1987 but differs in structural details of the genital organs, primarily by the presence of a well-developed retrolateral tibial apophysis, a hook-shaped distal end of the radix in the male palp, and the rectangular posterior median plate in the epigyne. The illustration of copulatory organs of (Clerck, 1757) and Zhu, Chen & Sha, 1987 were reproduced here for comparison.

Field survey of Cassidinae beetles (Coleoptera, Chrysomelidae) and their host plants in southern Guangxi, China.

Few systematic studies have been conducted on the faunal composition and food web structure of Cassidinae of China. During 2013-2019, we systematically investigated Cassidinae beetles and their host plants in the southern Guangxi. A total of 2,255 Cassidinae individuals from 66 species, 23 genera and ten tribes were collected in southern Guangxi.

A checklist of gymnosperm-feeding leafminers (Arthopoda, Insecta) in North America and Europe.

The leafminers on gymnosperms receive much less attention than those on either angiosperms or ferns. Given the distinctly different leaf shape and leaf venation found in gymnosperms, they would be expected to host significantly different leafminer groups. Very few comprehensive reports on gymnosperm-feeding leafminers have been presented.

Midgut bacterial diversity of a leaf-mining beetle, (Gestro) (Coleoptera: Chrysomelidae: Cassidinae).

Microorganisms play an essential role in the growth and development of numerous insect species. In this study, the total DNA from the midgut of adults of were isolated and bacterial 16S rRNA sequenced using the high-throughput Illumina MiSeq platform. Then, the composition and diversity of the midgut bacterial community were analysed with QIIME2.

A preliminary world checklist of fern-mining insects.

Compared to the leaf-miners and stem-miners on flowering plants, the miners on ferns (including both Lycopodiophyta and Polypodiophyta in the broad sense) are less known. Knowledge of miners and their host plants is essential to fully understand plant-insect interactions. Although there are many scattered records on fern miners, a worldwide checklist has not been reported.

A new species of Tu, Li & Rollard, 2005 (Araneae, Linyphiidae) from Yunnan, China.

(♂♀) is described from Yunnan, China. Detailed descriptions of somatic features, genitalic characters, photos of habitus of the new species as well as of copulatory organs of (Schenkel, 1963) (♂♀) are presented. A distribution map is also provided.

The Cassidinae beetles of Longnan County (Jiangxi, China): overview and community composition.

There are few reports on the community composition and diversity pattern of the Cassidinae species of China. Compared to the neighbouring provinces of Guangdong, Fujian and Zhejiang, the Cassidinae richness in Jiangxi Province is under-reported. Longnan City, a biodiversity hotspot in Jiangxi Province, was chosen to obtain the first overview of the Cassidinae beetles.

Are dominant plant species more susceptible to leaf-mining insects? A case study at Saihanwula Nature Reserve, China.

Dominant species significantly affect interspecific relationships, community structure, and ecosystem function. In the field, dominant species are often identified by their high importance values. Selective foraging on dominant species is a common phenomenon in ecology.

Description of immature stages and biological notes of Medvedev, 1957, a newly recorded species from China (Coleoptera, Chrysomelidae, Cassidinae, Hispini).

The first instar and mature larva and pupa of Medvedev, 1957, a newly recorded species from China, are described and figured. The chaetotaxy of the head, mouthparts, legs, and dorsal and ventral surfaces of the body is described. This is the first detailed description of immatures in the genus .

Global mtDNA genetic structure and hypothesized invasion history of a major pest of citrus, (Hemiptera: Liviidae).

The Asian citrus psyllid Kuwayama is a key pest of citrus as the vector of the bacterium causing the "huanglongbing" disease (HLB). To assess the global mtDNA population genetic structure, and possible dispersal history of the pest, we investigated genetic variation at the gene collating newly collected samples with all previously published data. Our dataset consists of 356 colonies from 106 geographic sites worldwide.

Global pattern of plant utilization across different organisms: Does plant apparency or plant phylogeny matter?

The present study is the first to consider human and nonhuman consumers together to reveal several general patterns of plant utilization. We provide evidence that at a global scale, plant apparency and phylogenetic isolation can be important predictors of plant utilization and consumer diversity. Using the number of species or genera or the distribution area of each plant family as the island "area" and the minimum phylogenetic distance to common plant families as the island "distance", we fitted presence-area relationships and presence-distance relationships with a binomial GLM (generalized linear model) with a logit link.
