Redescription. Measurements (in mm) and ratios: BL 3.73–3.90; FL 2.76–2.84; HL 0.53–0.56; HW 0.65–0.68; PL 0.71–0.74; PW 0.90–0.96; EL 1.49–1.61; EW 1.33–1.43, HL/HW 0.77–0.86; PL/PW 0.74–0.80; EL/EW 1.09–1.16; HW/PW 0.70–0.73; PL/EL 0.44–0.48; AnL 1.35–1.38; AeL 0.63–0.69.
Habitus as in Fig. 12B. Reddish brown or darker; head, median dorsal portion of pronotum and abdomen blackish brown; antennomeres I–II and base of antennomere III rufo-testaceous, antennomeres IV–XI infuscate; elytra blackish brown, with obscure oblique fusiform reddish brown maculae, extending from shoulder toward suture in middle; tarsi yellowish. Pubescence pale, dense and recumbent on whole body.
Head subtriangular, coarsely and sparsely punctate, widest across eyes; eyes moderately prominent, 2.60 times longer than temples; ocelli distinct, distance between ocelli 2.30 times as long as distance between ocellus and inner margin of the compound eye. Antennae short, relative lengths of the antennomeres I–XI: 1.54: 1.08: 1.08: 1: 1: 1: 1: 1: 1.08: 1.08: 1.54.
Pronotum subcordate and somewhat convex in dorsal view, apparently transverse widest at anterior middle, with discal impression; lateral margins arcuate, with very deep foveae at middle, then narrowing anteriad and posteriad; punctation and pubescence similar to that of head. Scutellum subtriangular, finely and densely punctate.
Elytra subtrapezoidal, gradually dilated posteriorly, posterior angles broadly rounded, with crescent-shaped deep impression; punctation and pubescence distinctly finer and sparser than those on pronotum.
Abdomen broad, widest at segment IV, distinctly narrowed posteriorly; surface of each tergite somewhat closely covered with very fine punctation, with distinct microsculpture; middle of the tergites IV and V with pair of tomentose patches.
Male. Apical margin of tergite VIII (Fig. 13G) with weak concavity; sternite VIII (Fig. 13H) transverse, apical margin strongly concave; median lobe of aedeagus (Figs 15 D–F) wide apically, slightly shorter than parameres; parameres somewhat asymmetrical.
Female. Sternite VIII without concave apical margin, otherwise similar to males.
Comment. The original description is based on a female specimens collected in Mt. Qinling, Shaanxi (Rougemont 2000). The above records from Hebei represent new provincial records (Fig. 33). For illustrations of L. rufimarginata see Figs 17B, 18 G–H, 20D–F and Rougemont (2000: fig. 11).
