description: <i>Anomalophylla kangdingensis</i> sp. n. (Fig. 3N–P, 8) <i>Type material.</i> Holotype: ♂ " CHINA: W­Sichuan (Ganzi Tibet Auton. Pref. Kangding Co.) Daxue Shan, river valley 15 km S Kangding, 29°56'N / 101°58'E, 2800 m 26.VI.1999 leg. D. Wrase " (ZSM). <i>Holotype description.</i> Length: 5.8 mm, length of elytra: 3.7 mm, width: 3.0 mm. Body oblong, legs black; dorsal surface dull; head and pronotum with long, dense, yellowish brown, erect setae. <i>Head:</i> Labroclypeus transverse, widest at base; with lateral margins strongly convex, strongly convergent anteriorly, subparallel in basal half; anterior angles strongly rounded; lateral border and ocular canthus producing distinct blunt angle; anterior and lateral margin moderately reflexed; anterior margin shallowly sinuate medially; surface almost flat medially, moderately shiny with double punctation; coarse, dense punctures mixed with fine glabrous punctures; coarse punctures each bearing a long, erect seta. Frontoclypeal suture weakly incised, weakly curved; smooth area anterior to eye as wide as long. Ocular canthus long, slender; lateral margin concavely sinuate; finely, densely punctate with a few long setae. Frons dull; anterior two­thirds with coarse, dense punctures mixed with fine glabrous ones; punctation less dense posteriorly, predominantly fine, almost glabrous; a few punctures behind frontoclypeal suture adjacent to eyes bearing setae. Eyes small, ratio of diameter / interocular width: 0.5. Antenna with ten antennomeres, brown; club with five equal in length antennomeres; club 2.5 times as long as remaining antennomeres combined, reflexed. Prementum weakly elevated, transversely carinate; distinctly concave apical to elevation. <i>Pronotum:</i> widest at base; lateral margins in posterior half weakly convex, in anterior half strongly convex and convergent; anterior angles weakly produced, strongly rounded; posterior angles weakly rounded; anterior margin medially weakly convex with distinct, fine marginal line; basal margin medially without a fine marginal line. Pronotal surface with moderately dense, double punctation; fine, glabrous punctures mixed with large moderately dense punctures, each bearing a long erect seta. Anterior and lateral borders setose; basal margin of hypomeron not produced ventrally, not transversely sulcate anterior to base. <i>Scutellum:</i> dark and moderately wide; apex moderately sharp; with fine and sparse punctures; medially narrowly impunctate; minute setae present in punctures. <i>Elytra:</i> oblong, widest medially; striae weakly impressed, finely punctate; intervals weakly convex with fine punctures along striae; a few punctures on odd intervals bearing a long, appressed 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 glabrous adjacent to articulation of leg; elsewhere with 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 / 1.56. Pygidium moderately convex, dull; with fine, dense punctures; punctures bearing fine, moderately long setae; without smooth midline. <i>Legs</i>: slender with shiny surface. Femora with two longitudinal rows of setae; finely, densely punctate, 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 / 3.4; dorsal edge sharply carinate, finely serrate, 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 moderately dense, fine punctures; ventral edge serrated, with three strong, long, equally spaced spines; medial face impunctate; apex interiorly near tarsal articulation deeply, sharply truncate. Tarsomeres dorsally glabrous, finely punctate; ventrally with sparse, short setae; metatarsomeres dorsally without longitudinal impressions, ventrally with strongly serrated ridge adjacent to indistinct longitudinal carina, laterally with strong longitudinal carina; first metatarsomere distinctly shorter than following two tarsomeres combined, slightly longer than upper tibial spur. Protibia short, bidentate. Protarsal claws asymmetrical, basal tooth of inner protarsal claw apically widened, truncate. <i>Aedeagus:</i> Fig. 3N–P. <i>Diagnosis.</i> The new species differs from the similar <i>A. kozlovi</i> by the more produced anterior angles of the pronotum as well as by the shape of parameres (Fig. 3N–P). The right paramere is straight and posses a slightly longer basal lobe, the left paramere is not widened medially in dorsal view. <i>Etymology.</i> The new species is named according to its occurrence near to the city Kangding.
