description: <i>Anomalophylla plagipennis</i> sp. n. (Fig. 4Q–S, 8) <i>Type material.</i> Holotype: ♂ " China; Yunnan; 1995; Habashan mts.; 2500–3800 m 27°20'N 100°11'E; 3.–6.vi.; SE Slope; S. Be č va ř leg." (MMBC via TICB). Paratypes: 3 ♀♀ ­ same data as holotype (TICB, CA), 1 ♂ " CHINA VI, 1990 Lijiang leg. Bocák " (CA), 2 ♂♂ " China: N. Yunnan 30 km N of Lijiang 3000 m, 3.VII.1990 L. &amp; M. Bocák lgt." (NHMB). <i>Holotype description.</i> Length: 4.8 mm, length of elytra: 2.9 mm, width: 2.6 mm. Body oblong, black; legs and elytra reddish brown, the latter with apical half, sutural and lateral intervals black; dorsal surface dull; head and pronotum with long, dense, erect setae; pilosity on elytra moderately dense; pilosity yellowish brown. <i>Head:</i> Labroclypeus transverse, widest medially with lateral margins strongly convex, convergent anteriorly and toward base; anterior angles strongly rounded; lateral border and ocular canthus producing distinct blunt angle; anterior and lateral margin strongly reflexed; anterior margin moderately sinuate medially; surface almost flat medially, moderately shiny with double punctation; fine, glabrous punctures mixed with coarse, dense punctures each bearing a long, erect seta. Frontoclypeal suture distinct; weakly curved, slightly elevated; smooth area anterior to eye as wide as long. Ocular canthus moderately long and slender; finely, densely punctate; densely setose. Frons with double punctation; fine glabrous mixed with coarse, dense punctures each bearing a long, erect seta; punctation less dense, glabrous basally. Eyes small, ratio of diameter / interocular width: 0.47. Antenna with ten antennomeres, yellowish brown; club brown, with five equal in length antennomeres; club 2.5 times as long as remaining antennomeres combined, reflexed. Prementum weakly elevated, transversely carinate. <i>Pronotum:</i> widest at base; lateral margins in basal half almost straight and subparallel, in apical third strongly convex and convergent; anterior angles not produced and moderately rounded; posterior angles blunt, weakly rounded; anterior margin medially weakly convex with distinct, fine marginal line; basal margin with fine marginal line. Pronotal surface with dense, double punctation; fine, glabrous punctures mixed with large punctures bearing a long erect seta; pilosity moderately dense. Anterior and lateral borders setose; basal margin of hypomeron not produced ventrally, not transversely sulcate anterior to base. <i>Scutellum:</i> moderately long; apex sharp; with fine, dense punctures; minute setae present in punctures. <i>Elytra:</i> oblong, widest medially; striae indistinctly impressed, finely densely punctate; intervals flat, with fine, moderately dense punctures; punctures on odd intervals with long, erect setae, which are anteriorly longer and denser; sutural interval with robust, long, single seta. Epipleural edge fine, ending at strongly convex external apical angle of elytra; epipleura densely setose, strongly curved in anterior third of elytra; apical border chitinous, without short microtrichomes. <i>Venter:</i> Ventral surface dull with fine, dense punctures. Metasternum with dense, long setae, setae partially appressed, partially erect. Metacoxa almost glabrous; laterally with moderately dense, fine, long appressed setae. Abdominal sternites with indistinct transverse row of coarse punctures bearing thick setae between fine, dense punctation; all abdominal sternites with fine, long setae; tegument of abdominal sternites (60x magnification) with fine polygonal mesh pattern formed by microtrichomes; penultimate sternite at midline with longitudinally impressed line. Mesosternum between mesocoxae narrow, narrower than mesofemur, with irregularly scattered, strong setae. Ratio of length of metepisternum/ metacoxa: 1/1.67. Pygidium moderately convex, posteriorly shiny; with fine, dense punctures bearing fine, long setae; pilosity denser along apical margin; without smooth midline. <i>Legs:</i> slender with shiny surface. Femora with two longitudinal rows of setae; rows finely, densely punctate and setose; anterior edge of metafemur acute, lacking adjacent serrated line; posterior margin weakly convex with a few fine setae medially; ventral posterior margin weakly widened in apical half, posterior margin smooth ventrally and dorsally. Metatibia moderately slender, long, widest at apex; ratio width/length: 1/3.5; dorsal margin sharply carinate, smooth; with two groups of spines, basal group at one third, apical one at two thirds of metatibial length, basally with a few single spines in punctures; lateral face longitudinally convex with dense, fine punctures; ventral edge serrated, with four strong, long, equally spaced spines; medial face finely punctate, apex sharply truncate interiorly near tarsal articulation. Tarsomeres dorsally glabrous, coarsely punctate; ventrally with sparse, short setae; metatarsomeres dorsally without longitudinal impressions, ventrally with strongly serrated ridge adjacent to strong longitudinal carina, laterally without strong longitudinal carina; first metatarsomere slightly shorter than the following two tarsomeres combined, slightly longer than upper tibial spur. Protibia short, bidentate. Protarsal claws asymmetrical; basal tooth of inner protarsal claw widened, truncate apically. <i>Aedeagus:</i> Fig. 4Q S. <i>Intraspecific variation.</i> Length: 4.8 mm, length of elytra: 2.9 mm, width: 2.6 mm. Coloration variable, one paratype legs completely black, extension of dark portion of the reddish brown elytra half of elytral length or less. Density of punctation on dorsal surface variable. ♀: antennal club with three antennomeres and distinctly shorter than the remaining antennomeres combined; eyes equal in size to that of male. <i>Diagnosis. Anomalophylla plagipennis</i> strongly resembles <i>A. dongchuanensis</i>. It differs by the left paramere, which is medially tooth­like, widened, and distinctly sinuate basal to the widest section. The lateral apophysis of phallobase is in <i>A. plagipennis</i> narrower and more sharply pointed at apex. <i>Etymology.</i> From the combined Latin words <i>plaga</i> (stain) and <i>penna</i> (wing).
