We describe apterous and alate viviparous females of a new species of the Lachninae genus Eulachnus (Eulachnini) from China. The new species, Eulachnus blackmani sp. nov., can be easily separated from other Asian representatives of this genus: the ultimate rostral segments are without accessory setae; the spinal scleroites are larger than the pleural and marginal ones; there are a few very long setae on the distal part of the tibiae and on the hind tarsus. The new species is morphologically most similar to the European E. nigricola (Paek), and hence unusual within the Asian Eulachnus fauna.

Paper presents the phenomenon of thanatosis or death-feigning in selected aphids species. This specific reaction was predominantly analysed on the example of aphid subfamily Lachninae. Individuals of this group were used in experiments, during which a thanatotic response was induced with various results.

The aphid genus Eulachnus in Europe is revised to include 12 species, using an integrative taxonomy approach, based on morphometric, molecular and biological traits. Fundatrix, apterous and alate viviparous female of a new species-Eulachnus stekolshchikovi Kanturski sp. nov.

Scanning electron microscopy (SEM) methods were used for the first time to elucidate the external morphology of the European species of the genus Eulachnus (Hemiptera: Aphididae: Lachninae), a representative genus of the conifer-feeding aphids tribe Eulachnini. We examined and compared the external morphology of apterous and alate viviparous females from the parthenogenetic generation as well as oviparous females and alate males belonging to the sexual generation. FE-SEM images based on HMDS and cryo-SEM preparation techniques revealed better image quality than the CPD technique in regard to surface tension and morphological signs of cell deteriorations (i.
