Abstract

Although in “Fauna Sinica Insecta” 247 species of Phaneropterinae are recorded for China, there is not a single record of a species from the tribe Barbitistini. Herein, we newly record a small-sized and short-winged species of this tribe belonging to the genus Poecilimon (Fischer, 1853). We identified the species as Poecilimon intermedius (Fieber, 1853) which was collected in the Xinjiang Uygur Autonomous region, China. The records of the interesting species extend its distributional range in Asia. Detailed citations, description and necessary illustrations are provided.

Key words: Barbitistini, Poecilimon, China, new record of Phaneropterinae

Introduction

The tettigoniid subfamily Phaneropterinae is very rich in species in China. In the most recent review, over 247 spe- cies of this group were recorded in China, belonging to 47 genera from the five tribes Ducetiini, Elimaeini, Holo- chlorini, Mirollini and Phaneropterini (Kang et al. 2014). However, as an exception not any record and specimen of species from tribe Barbitistini was recorded from China. Species of the tribe Barbitistini are short-winged and mostly small-sized, and they are widely distributed in temperate forests, Taiga, and grassland in Western Eurasia. The tribe includes 14 valid genera and 282 species with 64 subspecies (Cigliano et al. 2019). Only a few species of Poecilimon Fischer extend into some countries of cen- tral Asia, and some species of Fieber and Brunner von Wattenwyl are only distributed in South Western Asia (mainly Turkey). The genus Poecilimon Fischer is one of the most species-rich genera of the Phaneropterinae. Currently it in- cludes 142 species with 40 subspecies, distributed from Europe to Central Asia. The species distributed most east- wards is P. intermedius (Fieber, 1853), a member of the Poecilimon ampliatus-group, which can easily be recog- nized by the red/dark midline of the pronotum (see Heller & Lehmann 2004; p.413 intermedius). P. intermedius is one of the few species known with obligate but diploid parthenogenetic reproduction (Lehmann et al. 2007; Lehmann et al. 2011). Males have never been found; some old records of males are considered as misidentifica- tions. However, a male may appear if the female loses one of her X-chromosomes in early embryonic development (Heller, personal communication). The auditory sensitivity was largely reduced in the parthenogenetic bushcricket females (Lehmann et al. 2007; Strauß et al. 2014), but hearing was clearly maintained (Lehmann 2012). P. inter- medius occurs in the Eastern European-West Asian xero-mesophytic steppe grasslands, which are probable natural habitat patches fragmented in the forest steppe zone (Kenyeres & Bauer 2008). Herein, we report for first time the tribe Barbitistini in temperate Betula platyphylla Sukaczev forest in Aletai area in Xinjiang Uygur Autonomous Region, China, represented by the interesting species P. intermedius. Thus the distribution range of the tribe Barbitistini, the genus Poecilimon and the species P. intermedius extends from West Europe to northwestern area of Central East Asia. The specimens are deposited in the Collection of Institute of Zool- ogy, Chinese Academy of Sciences.

Discussion

This is the first time that the tribe Barbitistini is recorded in China. Members of this tribe are difficult to identify to the genus or species level, especially for female specimens, due to large number of species and some unclear historical records. According to the female ovipositor, we judge that the specimens collected from Xinjiang belong to Poecilimon ampliatus species group with all species except one distributed in Eastern Europe and Turkey. Usu- ally it is better to add male for robust identification to species, however, one species P. intermedius of the group is obligately parthenogenetic with a huge range up to Siberia and Kirgistan (Bey-Bienko 1954). For the species P. intermedius (Fieber), the previous male records are probably due to misidentification (Heller & Lehmann 2004). Then for the time being, we identify Xinjiang female specimens as P. intermedius (Fieber).
