Note. The original manuscript title "Doppelgänger in Tenthredo..." was changed by the editor of the journal.

The specimens examined with scanning electron microscopy (SEM) were uncoated. These images were taken with a SEM JSM-6060LV (Jeol) or with a Keyence VHX-D510 Digital SEM/Microscope.
Other photos were taken with a Leica DFC 495 digital camera and a Leica M405 C stereomicroscope. Composite images with an extended depth of field were created from stacks of images using the software CombineZP, and finally arranged and partly enhanced with Ulead PhotoImpact X3. Micosoft Image Composite Editor (ICE) was used to stitch together images of large  specimens.

Abstract of the paper:

Three pairs of species of Tenthredo with a probably allopatric distribution in Japan (and Sakhalin) and the Asian Mainland are treated. Tenthredo leleji sp.n., a species similar to Tenthredo eburata Konow, 1900 is described from Japan and Sakhalin. Tenthredo tenuipennis Malaise, 1931, sp.rev. is removed from synonymy with Tenthredo hilaris F. Smith, 1874. The differences between Tenthredo jonoensis Matsumura, 1912 and Tenthredo cockerelli (Rohwer, 1925) are described and illustrated. Lectotypes are designated for Tenthredo eburata Konow, 1900, Tenthredo jonoensis Matsumura, 1912, Tenthredo vitta Enslin, 1920, and Tenthredo tenuipennis Malaise, 1931.
