A revision of the Jurassic Stonefly Genera Dobbertiniopteryx Ansorge and Karanemoura Sinitshenkova (Insecta: Plecoptera), with the description of new species from the Daohugou locality, China

The stonefly genera Dobbertiniopteryx Ansorge and Karanemoura Sinitshenkova are revised. Based on new material from the Middle Jurassic of Daohugou, China, two new species, D. juracapnia sp. nov. and K. manca sp. nov., are described and Karanemoura abrupta Sinitshenkova, 1987 is redescribed. K. desiliens Sinitshenkova, 1987 is excluded from Karanemoura; its position within the family Perlariopseidae remains uncertain. The placement of Dobbertiniopteryx in the modern family Capniidae is confirmed. The perfect state of preservation of the nearly complete adult stonefly remains from China made it possible to improve and extend the diagnoses of the Perlariopseidae and Dobbertiniopteryx. The geological background of the Daohugou deposits is briefly discussed.
