(Figs 51–53, 57–58)  
 Panzeria linguacercus Zeegers, 2017: 20. Holotype male (SDEI, not examined). Type locality: Russia, Khabarobsk.   
 Diagnosis. This species closely resembles P. rudis (Fallén), but may be distinguished from it by the wider frons, broader male cerci and female fore tarsus not dilated (Zeegers 2017). Parafacial bare; palpus yellow; apical scutellar setae present; 4 postsutural dorsocentral setae; anatergite bare; frons at narrowest point about 0.14–0.16 of head width in male, about 0.28–0.29 in female; female fore leg with weakly dilated apical 3 tarsomeres, 5th tarsomere slightly longer than wide.   
 Description. Body length: 9.2–13 mm.   
 Terminalia. Male: 6th abdominal tergite with thin grayish pruinosity, bearing a row of rather fine setae mixed with fine hairs near posterior margin, about 1/3 as long as syntergosternite 7+8, narrowly separated from the latter; syntergosternite 7+8 shining black; epandrium with very thin grayish pruinosity; cerci in dorsal view broad at base and narrowed posteriorly to basal 1/3, then parallel-sided to rounded apex, in lateral view nearly straight, evenly narrowed posteriorly, apex weakly curved and pointed; surstylus short and broad, nearly triangular, with long dense setae on anterodorsal portion and 3–4 short spines on apical portion; pregonite with a fine seta near middle.   
Female: 6th tergite short, rather narrowly separated mid-dorsally, a row of strong setae on posterior margin, mixed with some fine hairs; 6th and 7th spiracles on ventral portion of 6th tergite; 6th sternite 2 times as long as 6th tergite; 7th tergite separated mid-dorsally into hemitergites, about 1.5 times as long as 6th tergite, with a row of short, fine setae on posterior margin; 7th sternite nearly as long as 6th sternite, narrower than the latter; 8th tergite reduced to small hemitergites, about 1/2 as long as 7th tergite; epiproct small, wider than long, with 4 fine setae.  
 Material examined from Japan (all in KUM). Honshu: 1 female, Iwate Pref., Iwaizumi Town, Akka, 20.vii.2001, H. Shima; 1 female, Saitama Pref., Yorii, Mikayama, 15.v.1983, K. Hara; 1 male, Saitama, Yorii, Mt. Kanetsukido, 27.iv.1986, T. Nambu; 1 male, Saitama, Minano, Ohbuchi, 6.v.1976, K. Hara; 1 male, Saitama, Ohtaki, Irikawa, 23.v.1986, K. Hara. Shikoku: 1 male, Ehime Pref., Kumakogen, Yurano, 21.v.2007, Malaise trap, E. Yamamoto. Kyushu: 1 female, Fukuoka City, Mt. Aburayama, 15.v.1989, H. Shima; 1 male, Fukuoka Pref., Dazaifu City, Mt. Shioji, 4.v.2016, H. Shima; 2 males, Fukuoka Pref., Mt. Kusenbu, 24.v.2007, 26.v.2015, H. Shima; 1 male, Ohita Pref., Mts. Kuju, Yoshibu, 31.v.1979, H. Shima.   
 Distribution. Japan (Honshu, Shikoku, Kyushu); Russia (Khabarovsk).   
 Remarks. This species was recently described from Khabarovsk, Far East Russia (Zeegers 2017). Although I have not seen the type of P. linguacercus, I think the above Japanese specimens are well assignable to this species. Panzeria linguacercus occurs synchronically and sympatrically with P. rudis (Fallén), which is similar in general appearance and genital structure. It appears to be less common than P. rudis in Japan.
