Baltileuctra gen. nov., a new genus of Leuctridae (Insecta: Plecoptera) in Baltic amber

A new genus and species of the stonefly family Leuctridae, Baltileuctra foraminis gen. et sp. nov., is described and illustrated based on a well-preserved male specimen from the Eocene Baltic amber. The new genus possesses typical characters of Leuctridae but has diagnostic characters of the thoracic sclerites and terminalia. The relationship between the new genus and other leuctrids is briefly discussed.

Discovery of a new stonefly genus with three new species from mid-Cretaceous Burmese amber (Plecoptera: Perlidae)

A new fossil stonefly genus of the subfamily Acroneuriinae Klapálek, 1914 (Plecoptera: Perlidae), Largusoperla gen. nov. is reported based on three well-preserved specimens in mid-Cretaceous amber from northern Myanmar. Three new species of this new genus, L. acus sp. nov, L. flata sp. nov and L. arcus sp. nov. are described and illustrated. This is the first report of stonefly specimens from mid-Cretaceous Burmese amber. The taxonomic placement of the new genus is discussed.

Pinguisoperla, a new fossil genus of Perlidae (Insecta: Plecoptera) from mid-Cretaceous Burmese amber

The new genus is characterized by its dark coloration and the basally enlarged and curved cerci. Morphological characters of the new genus and species are described, illustrated, and compared with related taxa.

A new species of Neoperla (Plecoptera: Perlidae) from Zhejiang Province of China

A remarkable new species of winter stonefly (Plecoptera: Capniidae) from Southeastern China

A new species of the genus Capnia s.l., C. zijinshana Du & Chen, sp. nov. is described and illustrated from Jiangsu Province, of southeastern China. The new species is distinguished from other known Chinese capniid species by the unique thoracic sclerites and genitalic characters.

A new species of Suwallia (Plecoptera: Chloroperlidae) from China

A new species of the genus Suwallia, S. wolongshana sp. nov. is described and illustrated from specimens collected in Sichuan Province, China. The new species is characterized by the two sclerotized bands between the hemitergal processes. The new species is the fourth recorded species of Suwallia from China.

The first record of a species of Perlidae from Jiangsu Province, China: a new species of Neoperla (Plecoptera: Perlidae).

A new species of Neoperla (Plecoptera, Perlidae), N. jiangsuensis Chen & Du from Jiangsu Province, China, is described and illustrated. Neoperla jiangsuensis is characterized by the aedeagal sac with two C-shaped rows of large stout spines laterally, a patch of small spines, and with an apical double ear-shaped membranous lobes. The new species is the first recorded species of Perlidae known from the eastern coastal province of Jiangsu, China.

A checklist and adult key to the Chinese stonefly (Plecoptera) genera

The first checklist of the known stonefly genera of China is presented. Using relevant literature and available specimens, a diagnostic key to the ten families representing 65 genera is provided. In addition, illustrations for the key characters are provided.

Description of Euroleuctra gen. nov., a new fossil genus of Leuctridae (Insecta: Plecoptera) in Eocene Baltic amber
