Review of the Chinese Stomis, with description of nine new taxa and a new key (Carabidae: Pterostichini) Author Sciaky, Riccardo text Zootaxa 2024 2024-10-14 5523 1 1 34 http://dx.doi.org/10.11646/zootaxa.5523.1.1 journal article 10.11646/zootaxa.5523.1.1 1175-5326 13933848 D8F096C8-5701-4FE8-B17A-77CA0126BB60 Stomis vignai ssp. taibashanensis Lassalle, 2003 stat. nov. Loc. typ.: Shaanxi , 2460 m , Mts Taibashan, N.O. Haozhenji . = Stomis fallettii Facchini, 2003 syn. nov. Loc. typ.: Shaanxi , Zhangliang, Fengxian. Lassalle (2003) described S. taibashanensis from Shaanxi , but almost at the same time Facchini (2003) described S. fallettii , also from Shaanxi . Examining the holotypes of S. taibashanensis and S. fallettii and more material collected later, I realized that the two are synonyms, sharing all their main features; S. fallettii was collected in a locality slightly different from that of S. taibashanensis , but it is certainly a synonym. The small tooth visible in dorsal view on the aedeagal apex is not represented in Lassalle’s drawing, but can be clearly observed on the specimens examined by me, among which a topotypical paratype . Lassalle’s work is dated June 2003 , while Facchini’s paper was published in December of the same year. Therefore I can state the new state: Stomis taibashanensis Lassalle, 2003 = S. vignai ssp. taibashanensis Lassalle, 2003 stat. nov. and the new synonymy: Stomis fallettii Facchini, 2003 = S. vignai ssp. taibashanensis Lassalle, 2003 syn. nov. Description. The combination of characters allowing to distinguish this subspecies are: length rather short ( 8.1–8.7 mm .), pronotal margins not sinuate towards base and less constricted than in the other subspecies ( Fig. 2 ), in most of the specimens with multiple anterolateral setae; elytra short and markedly oval; aedeagus long and slender, in lateral view feebly sinuate before apex ( Fig. 30 ). Ratios: El/Pl = 2.12; Ew/Pw = 1.25; El/Ew = 1.57. Material examined : Shaanxi , 2460 m , Mts Taibashan, N.O. Haozhenji : 1 Paratype ♂ ( CF ); Shaanxi , Zhangliang , Fengxian , 19.VII.2002 , leg. L. Falletti : Holotype ♂ of S. fallettii ( CF ) ; Shanxi, Tschingling Mts., Taibeichan Nat. res. (= Shaanxi , Qin Ling Shan , Taibaishan Nat. res. ), 33° 53’ N 107° 49’ E , 2000 m , 10.VIII.2005 , V. Patrikeev leg.: 1 ♂ ( CS ); Shaanxi , Taibai Shan Mts. , Houzhenzi vil. , 33° 52’ N 107° 44’ E , 1500–2700 m , A. Plutenko leg.: 2 ♂ ( CW ). Distribution . This subspecies seems limited to the central part of Qin Ling Shan, a mountain chain that goes from west to east from the eastern borders of Gansu , through all the province of Shaanxi to the western borders of Henan . The highest peak of this chain is the Taibai Shan, that reaches 3767 m a.s.l. The Qin Ling Shan also represents the watershed between the Huang He and the Yangtze Kiang river basins.
