Lectotype description. Length: 4.8 mm, length of elytra: 3.3 mm, width: 2.8 mm. Body oblong, legs blackish brown; pronotum reddish brown; elytra yellowish with dark lateral borders; dorsal surface dull; brown pilosity on head, pronotum, elytra. Head: Labroclypeus transverse, widest medially; with lateral margins strongly convex, strongly convergent anteriorly, weakly convergent toward base; anterior angles moderately 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 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 terminal seta. Frons dull; in anterior two thirds with coarse, dense punctures mixed with fine glabrous punctures; posterior punctation less dense and predominantly fine, almost glabrous; a few punctures behind frontoclypeal suture and beside the eyes bearing setae. Eyes small, ratio of diameter / interocular width: 0.49. Antenna with ten antennomeres, brown; club with five equal in length antennomeres; club twice as long as the remaining antennomeres combined, reflexed. Prementum weakly elevated, transversely carinate, distinctly concave apical to elevation. Pronotum: widest at base; lateral margins in posterior half subparallel, in anterior half strongly convex and convergent; anterior angles not produced, strongly rounded; posterior angles weakly rounded; anterior margin medially weakly convex with distinct, fine marginal line; basal margin medially without fine marginal line. Pronotal surface with moderately dense, double punctation; with fine, glabrous punctures mixed with large punctures bearing a long erect seta. Anterior and lateral borders setose; basal margin of hypomeron not produced ventrally, not transversely sulcate anterior to base. Scutellum : dark and moderately wide; apex moderately sharp; with fine, sparse punctures; medially narrowly impunctate; minute setae present in punctures. Elytra: oblong, widest in posterior third; striae weakly impressed, finely punctate; intervals flat; sutural interval convex; intervals with fine punctures only along the striae; a few punctures on the odd intervals bearing a long and erect seta; setae of sutural interval more robust. 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. Venter: Ventral surface dull with fine, dense punctures. Metasternum 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 abdominal 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 / 1.58. Pygidium moderately convex, dull; with fine, dense punctures; apical punctures bearing fine, moderately long setae; without smooth midline. Legs: slender with shiny surface. Femora with two longitudinal rows of setae; 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 / 3.1; dorsally sharply margined, dorsal edge finely serrate with two groups of spines, the 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 and sharply truncate. Tarsomeres dorsally glabrous and finely 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 distinctly shorter than the following two tarsomeres combined and slightly longer than the upper tibial spur. Protibia short, bidentate. Protarsal claws asymmetrical, basal tooth of inner protarsal claw widened and truncate apically. Aedeagus: Fig. 3G–J .

Diagnosis. Anomalophylla kozlovi differs from all known Anomalophylla species by the strongly rounded and not produced anterior angles of pronotum and by the short pilosity of elytra (much shorter than one interval width). It differs from Anomalophylla mawi ( Arrow, 1946) by the dorsal edge of metatibia being not serrate and by the distally widened basal lobe of the right paramere.
