Two new species and records of (Plecoptera, Perlidae) from Yunnan, China.

Two new species of the stonefly genus , and are described from Yunnan Province of southwestern China based on the morphological and distributional data, and the new species are compared with two congeners, Chen & Du, 2016 and Stark & Sivec, 2015. Stark & Sivec, 2008 is recorded from Yunnan Province for the first time.

Two new species and one new record of (Plecoptera, Perlidae) from Guangxi Zhuang Autonomous Region, China.

Three species of the group are described from Guangxi Zhuang Autonomous Region of southern China, including two new species, and , and a new record for Guangxi: Wu & Claassen, 1934. Illustrations and color images are provided for the three species mentioned above, and the new species is compared with related congeners in the group. Notes on the distribution of the species known from Guangxi are also given.

Review of (Plecoptera, Perlidae) from China.

Three Chinese species of the genus are reviewed. A new species, , is proposed from Guangdong, southern China, and compared with related taxa. Wu, 1973 is confirmed from Hainan Province of China on the basis of re-examination of types from the island, but it is transferred to the genus and is placed as a synonym of (Banks, 1938).

Using the combined gene approach and multiple analytical methods to improve the phylogeny and classification of (Hymenoptera, Apidae) in China.

Bumble bees are vital to our agro-ecological system, with approximately 250 species reported around the world in the single genus . However, the health of bumble bees is threatened by multiple factors: habitat loss, climate change, pesticide use, and disease caused by pathogens and parasites. It is therefore vitally important to have a fully developed phylogeny for bumble bee species as part of our conservation efforts.

Mitochondrial genomes of the stoneflies and (Plecoptera, Nemouridae), with a phylogenetic analysis of Nemouroidea.

In this study, two new mitochondrial genomes (mitogenomes) of and from the family Nemouridae (Insecta: Plecoptera) were sequenced. The mitogenome was a 15,739 bp circular DNA molecule, which was smaller than that of (15,778 bp) due to differences in the size of the A+T-rich region. Results show that gene content, gene arrangement, base composition, and codon usage were highly conserved in two species.

Two new species and one new regional record of from Guangxi, China, with additions to larval characters (Plecoptera, Nemouridae).

Two new species of Nemouridae of the genus Baumann, 1975, and , are described from Guangxi Zhuang Autonomous Region of southern China, on the basis of both sexes and larval stage. The affinities towards related species are discussed, together with generic characters of the larvae. (Li & Yang, 2007) is recorded from Guangxi for the first time, and its hitherto unknown female is described.
