In the present paper, two new species of the leafhopper genus Mitjaevia Dworakowska, 1970 from Guizhou Province China are described and illustrated, i.e., Mitjaevia shibingensis sp. nov. and Mitjaevia dworakowskae sp. nov. A checklist to species of the genus and a key to distinguish the Chinese species of the genus are given and the female valvulae are described and figured for the first time.


Checklist, distribution, Homoptera, identification key, morphology, taxonomy


The leafhopper genus Mitjaevia Dworakowska, 1970 belongs to the tribe Erythroneurini of Typhlocybinae, with Erythroneura amseli Dlabola, 1961 as its type species; seventeen species are known, seven from China (see Checklist). Two new species from Guizhou Province, China are described and illustrated in this paper together with a checklist and key to species from China.

Materials and methods

Specimens for this study were collected by sweep-net. Morphological terminology used follows Dietrich (2005) and Song and Li (2013) and observations and drawings were made using Olympus SZX16 and BX53 microscopes. Habitus photos were taken using a KEYENCE VHX-5000 digital microscope. Body measurements are from the apex of the vertex to the tip of the forewing. All specimens examined are deposited in the collection of the School of Karst Science, Guizhou Normal University, China (GZNU).


Mitjaevia Dworakowska, 1970

Mitjaevia Dworakowska, 1970: 763.

Type species

Erythroneura amseli Dlabola, 1961, by original designation.


Species with distinctive dark brown markings; head distinctly narrower than pronotum; male pygofer with simple dorsal appendage and sometimes ventral appendage; subgenital plate with a series of lateral peg-like setae basally or subbasally and a few macrosetae centrally at midlength; style elongate with subapical extension and variably developed lateral lobe; aedeagus with shaft cylindrical or laterally compressed, with or without processes, with ventral gonopore, basal apodeme variably developed and preatrium distinct.


Palaearctic and Oriental Regions.


Dworakowska (1970: 763–765) gave a detailed description of this genus based on the three included species known at that time; based on subsequently included species a modified description was given by Song et al. (2011: 26–27) and Dmitriev (2020). In addition, the female valvulae are described and figured here for the first time. Although a diagnosis is given above, clearly further studies are needed to elucidate fully the diagnostic characters of the genus and to test if the genus is monophyletic in the light of the observed variation in male genitalia between species.
