Cimberis attelaboides (Fabricius, 1787) ( Figs. 1–19 )

Redescription. Body moderately elongate, slightly convex; integument shiny, black ( Fig. 1 ); legs, antennae, and tip of rostrum yellowish brown; body with long, decumbent setae; setae around eyes on dorsal and ventral side of head erect. Rostrum moderately long, 0.65–0.75X as long as prothorax, generally expanded apically, slightly curved; posterior to antennal insertion, both sides gradually and gently curved and slightly expanded toward eye, with 1 low median longitudinal carina on metarostrum. Eye large, broadly oval, protruding. Antenna sparsely setose, reaching eye with base of desmomere 3; with 7 desmomeres; scape short, slightly longer than desmomere 1, subequal in width; desmomere 1 distinctly shorter and wider than 2; desmomeres 2–6 subequal in width; desmomere 7 slightly wider than 6; club loosely 3-segmented, elongate, subequal in length to last 4 desmomeres. Pronotum isodiametrical to transverse, 1.00–1.10X as wide as long, widest at middle; moderately curved on sides; anterior edge more or less straight; posterior edge slightly rounded; disc flat; integument punctate. Elytra (together) about 1.75‒1.79X longer than wide, about 2.87‒3.07X longer than pronotum; basal elytral margin slightly emarginate. Hindwing as in Fig. 19 . Mesonotum and metanotum as in Figs. 12, 13 , respectively. Metendosternite ( Figs. 2, 11 ) with slightly long stalk, robust and long furcal arms; hemiductus welldeveloped. Femora clavate; tibiae with ventral edge slightly incurved, with 2 apical spurs. Ventrites of male and female as in Figs. 1, 10 . In female, ventrite 2 with pair of small and round setiferous patches; ventrites 3 and 4 with large, transverse, elliptical setiferous patch; intercoxal process acute. Genitalia and terminalia: Male. Tergites VII and VIII as in Fig. 9 . Sternite VIII ( Fig. 8 ) strongly pigmented, with 2 crescentic hemisternites and 1 short rod-like apodeme connected by very weak membranes. Sternite IX ( Fig. 8 ) long, straight, with short arms. Aedeagus (or parts thereof) as in Figs. 3–7 ; temones moderately long; internal sac with long, strong Jshaped flagellum and blade-like sclerite ( Fig. 6 ).

Female. Tergites VII and VIII as in Fig. 18 . Sternite VIII as in Fig. 16 ; moderately strongly pigmented, with long, straight apodemes. Coxites and styli as in Figs. 14, 15 ; styli strongly pigmented. Spermatheca C-shaped, evenly broadly rounded at both apices ( Figs. 14, 17 ).

Variation. Males. Measurements (n = 3): Rostrum: length 0.50–0.56 mm; maximum width 0.39–0.41 mm.Pronotum:medial length 0.64–0.86 mm, maximum width 0.70–0.86 mm. Elytra: medial length 1.96–2.48 mm, maximum combined width 1.12–1.39 mm. Antenna: length 1.59–1.94 mm.

Females. Measurements (n = 6): Rostrum: length 0.60–0.68 mm, maximum width 0.42–0.45 mm. Pronotum: medial length 0.76–0.88 mm, maximum width 0.76–0.91 mm. Elytra: medial length 2.54–2.71 mm, maximum combined width 1.45– 1.58 mm. Antenna: length 1.68–1.92 mm. Females differ distinctly from males in having setiferous patches on ventrites 2–4, but some females lack such patches on ventrite 2.

Distribution. ASIA: China (Inner Mongolia), Kazakhstan, North Korea, Russia (East Siberia, Far East, West Siberia), Turkey. EUROPE: Austria, Bulgaria, Denmark, Finland, France, Great Britain, Germany, Hungary, Italy, Latvia, Lithuania, Luxembourg, the Netherlands, Norway, Russia (Central, North and South European Territory), Poland, Spain, Sweden, Switzerland.

The family Nemonychidae , the subfamily Cimberidinae , the tribe Cimberidini , and the species C. attelaboides are here reported as new country records for the fauna of China.

Ecology. From 26 May to 2 June 2014, 360 adults of C. attelaboides were collected by beating the branches of Pinus sylvestris L. var. mongolica Litv. at Honghuaerji, Inner Mongolia ( Fig. 20 ). Adults of C. attelaboides were observed on the male cones ( Fig. 21 ). Some specimens of Magdalis Germar and Pissodes Germar were also collected on the same tree on which C. attelaboides individuals were collected. More specimens of C. attelaboides were found and collected on trees in poor condition ( Fig. 22 ).
