Batrisiella aurita Löbl, 1973: 92 View in CoL . Type locality: North Korea.

Material examined. 1 3, 2 ƤƤ, labeled ‘ CHINA: Zhejiang Prov. / Hangzhou City / Zhuantang Town, CAA / 15.iii.2010, alt. 10 m / Zhi-Zhou YU leg.’ New record to China.

Redescription. Male. Reddish brown, length 1.70. Head wider than long, HL 0.35, HW 0.40, coarsely punctate below antennal tubercles, median carina distinct, eyes with about 35 facets; antennae long ( Fig. 5 View FIGURES 5 – 9 ). Pronotum as long as wide, PL and PW 0.40, disc lacking punctuations. Elytra slightly wider than long, EL 0.60, EW 0.66. Metafemora slightly broadened at posterior half, covered with sensory setae. Abdomen wider than long, AL 0.35, AW 0.56; tergite IV ( Figs. 10–11 View FIGURES 10 – 15 ) larger than V–VII combined, excavation located near apex, lateral setiferous patches small and indistinct, width between discal carinae 0.27. Length of aedeagus ( Figs. 16, 22 View FIGURES 16 – 28 ) 0.27.

Female. Similar to male in size, length 1.70–1.75, HL 0.34–0.35, HW 0.39–0.40, PL 0.41–0.42, PW 0.39–0.41, EL 0.48–0.50, EW 0.61–0.65, AL 0.47–0.48, AW 0.56–0.61. Eyes with about 20 facets. Metafemora not broadened, lacking sensory setae. Abdominal tergites simple. Width of female genitalia ( Fig. 29 View FIGURES 29 – 33 ) 0.18.

Remarks. This species is closely related to B. satoi . They share the excavation of tergite IV being located near the apex, the presence of a pair of small setiferous patches lateral to the excavation, and the unmodified tergite V in the male. They may be distinguished by the smaller size, the lack of a filament structure in the excavation, the modified male metafemora, and by the shapes of the male and female genitalia of B. auritus .

Distribution. North Korea, East China.
