description: <i>Anomalophylla ganhaiziensis</i> sp. n. (Fig. 4D–F, 8) <i>Type material.</i> Holotype: ♂ " Yunnan, 20–23.vii.1996, 27°05'N 100°13'E 3400 m, Yulong mts. Ganhaizi, Vit Kuban leg." (MMBC via TICB). <i>Holotype description.</i> Length: 6.1 mm, length of elytra: 3.6 mm, width: 3.1 mm. Body oblong, black, elytra dark­brown, in anterior third reddish brown; dorsal surface dull, head and pronotum with long, dense, erect setae; pilosity on elytra sparse; pilosity on head and anterior pronotum black, that of elytra yellowish brown. <i>Head:</i> Labroclypeus transverse, widest shortly behind middle 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 shallowly 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, slender; finely, densely punctate; densely setose. Frons with double punctation; fine, glabrous punctures mixed with coarse, moderately dense punctures each bearing a long, erect seta; basal punctation less dense, predominantly fine, almost glabrous. Eyes small, ratio of diameter / interocular width: 0.51. Antenna with ten antennomeres, brown; club darker 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 adjacent to base; lateral margins in basal half weakly convex and convergent anteriorly, in apical half strongly convex and convergent; anterior angles not produced, strongly rounded; posterior angles strongly 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 lacking at centre of disc; punctures each bearing a long erect seta; setae slightly directed anteriorly, weakly curved posteriorly. 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, sparse punctures; medially smooth; minute setae present in punctures. <i>Elytra:</i> oblong, widest medially; striae indistinctly impressed and finely, densely punctate; intervals weakly convex with fine, moderately dense punctures; punctures on all intervals with long, erect setae which are anteriorly longer, denser; punctures on even intervals only setose basally; sutural interval with robust, long single seta. Epipleural edge fine, ending at strongly convex external apical angle of elytra; epipleura densely setaceous, 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 near the articulation of the leg; elsewhere with fine, long appressed setae. Abdominal sternites with indistinct transverse row of coarse punctures bearing thick setae between fine, dense punctation; all 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, moderately long setae; without smooth midline. <i>Legs:</i> slender with shiny surface. Femora with two longitudinal rows of setae and 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 / 3.8; dorsally sharply margined; medial face of dorsal edge serrate, with two groups of spines, basal group at one quarter, 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 following two tarsomeres combined, one third of length longer than upper tibial spur. Protibia short, bidentate. Protarsal claws asymmetrical; basal tooth of inner protarsal claw widened, truncate apically. <i>Aedeagus:</i> Fig. 4D–F. <i>Diagnosis.</i> This species differs from the similar <i>A. huashanensis</i> by the shape of parameres (Fig. 4D–F): the medial dilatation of the left paramere is situated at the middle and sharply angled, while in <i>A. huashanensis</i> it is situated in the apical half of paramere, the basal lobe of <i>A. ganhaiziensis</i> is shorter than in <i>A. huashanensis</i>. <i>Etymology.</i> The new species is named after Ganhaizi, the type locality.
