Pterostichus (Tschitscherinea) filum ( Tschitschérine, 1897) View in CoL

Figure 6 View FIGURES 1–6

Chinese vernacular name: ũdzā±Ƥ

Tschitschérine 1897: 70 (Original: Feronia : subgen. Eunema ; holotype should be in MNHN, but probably missing; type locality: “Mou-Pin”); Jedlička 1962: 228.

Material examined. Non-type material: 1 female ( IZAS): “ Sichuan, Wolong, Wulidun, 2395m, Artificial larch forest, pitfall trap. 2004.VII.22–25, Xiaodong Yu leg. RG32–4, Institute of Zoology. ”

Diagnosis. This species is different from all the other members of this subgenus by the elytral interval 3 with only one setigerous pore. It is most similar to P. jiuzhaiicus sp. nov. Their comparison was already provided under the new species.

Supplementary description. BL = 9.5 mm, BW = 3.2 mm; eyes very small, tempora strongly swollen behind eyes, length greater than eyes, eyL/tpL = 0.52, maxim width of head at outer margin of tempora, HW/PW = 0.75. Pronotum parallel-sided, PW/PL = 1.03, PBW/PW = 0.83; anterior margin slightly wider than posterior margin, PAW/PBW = 1.04; lateral margins straight before posterior angles, posterior angles rectangular, not denticulate. Basal foveae densely punctate, without outer groove, inner groove faintly depressed. Elytra with transverse microsculpture; parascutellar pore absent; humerus with small stout tooth, faintly projected out; interval 3 with one setigerous pore near anterior third, adjacent to stria 2. Metatarsus slender in females, segment 1 with shallow outer-lateral ridge; males unknown.

Distribution. This species is known only from two close localities in Western Sichuan, the type locality Moupin in Baoxing county, and Wolong in Wenchuan county. ( Fig. 54 View FIGURES 54–57. 54 , pink)
