First discovery of the male of Teratura (Stenoteratura) kryzhanovskii (Bey-Bienko, 1957) (Orthoptera: Tettigoniidae: Meconematinae)

The subgenus Stenoteratura Gorochov, 1993 of the genus Teratura Redtenbacher, 1891 was proposed with Xiphidiopsis yunnanea Bey-Bienko, 1957 as the type species (Gorochov, 1993). The diagnosis of this subgenus is as follows: posterior processes of male 10th abdominal tergite narrow and rather short; cerci strongly curved, with teeth on the internal margins; apex of epiproct only with lateral hook-like processes; subgenital plate of female with short and wide apical half provided with 3 lobes. Up to now, the subgenus includes five species, namely T. (S.) bhutanica Ingrisch, 2002, T. (S.) janetscheki (Bey-Bienko, 1968), T. (S.) kryzhanovskii (Bey-Bienko, 1957), T. (S.) subtilis Gorochov et Kang, 2005, and T. (S.) yunnanea (Bey-Bienko, 1957) (Bey-Bienko, 1957, 1968; Ingrisch, 2002; Gorochov et al., 2005; Cigliano et al., 2018). Xiphidiopsis kryzhanovskii Bey-Bienko, 1957 was described based on the female type specimen collected in Jingdong, Yunnan. Later it was transferred to the subgenus Stenoteratura by Gorochov (1993). Until now, the male of this species is unknown. We collected a pair of specimens of this species (1 male and 1 female) in Jingdong, Yunnan Province in 2017. In this paper we describe the previously unknown male, give supplementary description of the female, and provide the morphological photographs. The specimens examined are preserved in the Museum of Hebei University (MHU).
