Scale bar: 0.2 mm.   FIGURE 11.Habitus (males) of  Lesteva: A—  L. elongata  sp. nov.; B—  L. erythra. Scale bar: 1.0 mm. Habitus as in Fig. 11A. Blackish brown; antennae and ocelli testaceous; elytra with distinct oblique testaceous maculae extending from the humeral angle to the suture at middle; femora fuscous, tibiae paler, tarsi yellowish. Body with pale pubescence, evident and recumbent. Head subtriangular, coarsely and sparsely punctate, widest across eyes; eyes moderately convex, 1.71 times longer than temples; ocelli distinct, distance between ocelli slightly more than twice as long as distance between ocellus and inner margin of eye. Antennae elongate, relative lengths of the antennomeres I–XI: 1.58: 1: 1.08: 1.08: 1.08: 1.17: 1.17: 1.08: 1.08: 1: 1.92. Pronotum subcordate, moderately convex and transverse, widest at anterior middle; lateral margins arcuate at anterior two-thirds and nearly straight at posterior third; punctation and pubescence similar to that on head; disc with shallow U-shaped depression. Scutellum subtriangular, surface with fine punctation and pubescence. Elytra subtrapezoidal, gradually dilated posteriorly, posterior angles broadly rounded; punctation and pubescence distinctly finer and sparser than those on pronotum. Abdomen broad, widest at segment IV (first visible abdominal segment) then narrowed posteriorly; surface of tergites closely covered with very fine punctation, without microsculpture; tomentose patches on first exposed tergite V small and less transverse. Male. Apical margin of the tergite VIII ( Fig. 13A) truncate; sternite VIII ( Fig. 13B) transverse, apical margin strongly concave; median lobe of the aedeagus ( Figs 14A–C) distinctly shorter than parameres, narrowing toward the apex; parameres somewhat asymmetrical, each slightly narrowed in anterior half, with four long apical setae; internal sac without sclerotized spines and without distinct dark membranous structures. Female. Abdominal sternite VIII without concavity apically. In other morphological characters similar with males.  Comparative notes.Based on the body size and coloration, as well as on the punctation and pubescence, the new species is most similar to  L. erythraMa, Li & Zhaofrom which it differs by the coloration of the legs, by the shape of maculae on elytra and morphology of the aedeagus. For illustrations of  L. erythrasee 11B, 13C–D, 14D–F and Ma, Li & Zhao (2012a: figs 2, 6–8).   Distribution and natural history. China: Zhejiang( Fig. 34). Some specimens were sifted from moss on rocks near a stream in mixed deciduous forests at Mt. East Tianmu, Zhejiang.   Etymology.The specific epithet alludes to the elongated parameres of the aedeagus. 2234227996 2005-05-09 2005-05-10 2005-05-09 Li China China 1080 Lin'an City Prov. 11 12 1 1 Zhejiang holotype 2234228004 SNUC China Cheng 11 12 1 Zhejiang holotype 2234227987 [309,1032,1989,2014] China CHINA 11 12 24 15 9 paratype 2234227995 [256,816,155,180] SNUC Cheng 12 13 5 4 1 2234227998 2006-05-19 Tang China Prov. 975 Mt.
